I Background
By Executive Order Governor David A Paterson created the State Energy Planning Board (SEPB) in April 2008 The Governor charged the Board with analyzing a broad range of matters related to the Statersquos energy systems including but not limited to the reliability of delivery networks for electricity natural gas and petroleum products and the interrelated effects of New Yorkrsquos production and use of energy on the Statersquos economy environment and transportation systems The Governorrsquos 2009 Energy Plan (Plan) will contain policies programs and strategies that will address these matters over the 2009 through 2018 planning horizon
As part of the Energy Plan an extensive multi-part computer modeling effort was undertaken to assess the effects of policies and programs recommended for adoption on a range of factors relevant to decision-makers Among them are the cost of electricity and capacity forecasted changes in the electricity and natural gas systems including the transfer capabilities of the transmission grid and emission levels of greenhouse gases and other pollutants
The NYISO supported the Statersquos development of the computer modeling effort by providing several technical white papers and reviewing the model assumptions and results
Based on the results of the Energy Plan assessment assumptions regarding the retirement or repowering of existing generating units and the installation of new units were made by the SEPB Working Group to meet the future capacity needs of the state and the environmental objectives The NYISO performed a reliability study using the GE Multi-Area Reliability Simulation (MARS) program version 292 The Reliability Study was conducted to verify that the SEPBrsquos assumed capacity modifications would not result in the violation of the Loss of Load Expectation (LOLE) criterion of once in 10 years (or 01 per year) as established by the Northeast Power Coordinating Council (NPCC) and the New York State Reliability Council (NYSRC) That criterion establishes that the resources available on the electric system in New York should be sufficient such that the probability of an unplanned outage on the bulk power grid is never greater than once in ten years
II Integrated Planning Model Analysis To support the Statersquos Integrated Planning Model (IPM) analysis the NYISO performed the following tasks
1 Provided to the State technical white papers in October and November 2008
2 Provided forecasting and other modeling assumptions used in the development of the 2009 Reliability Needs Assessment and 2009

III Reliability Assessment A Process
In order to assess the reliability of the capacity retirementsadditions resulting from the IPM study the NYISO modeled the SEPB Working Grouprsquos capacity recommendations in MARS and calculated the LOLE The SEPB Working Group developed two IPM base case models (Reference Cases) The first utilized the load forecast that was used in NYISO RNA study This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) and is referred to as the ldquoSEPB RNA Caserdquo The second reference case modelrsquos load forecast assumes that the full EEPS is achieved and is referred to as the ldquoSEPB 15 x 15 Caserdquo Since this case assumes a lower load forecast than the ldquoSEPB RNA Caserdquo it also assumes approximately 1500 MW less capacity The recommended capacity modifications for these two base (reference) cases are included as Exhibit C-1 in Appendix C
Four study years (2009 2012 2015 and 2018) were evaluated in MARS to determine the NYCA and Zonal LOLEs for each base case model
The following two scenarios were also evaluated for each of the two base cases
1 Addition of Nuclear Capacity Upstate 2 30 Renewable Portfolio Standard
More details regarding the development of the models for the Reliability Assessment are included in Appendix C
B Results 1 Base Models (Reference Cases)
No LOLE violations of 01 or greater occurred for all study years for both base cases provided that the assumed load forecast is

achieved However if the full 15 x 15 load forecast is not achieved an LOLE violation may occur for the ldquoSEPB 15 x 15 Caserdquo It was found that utilizing the higher load forecast from the ldquoSEPB RNA Caserdquo in the ldquoSEPB 15 x 15 Caserdquo an LOLE violation of 0102 would occur in NYCA in 2012 and would increase to 0627 by 2018
2 Scenarios i Upstate Nuclear Addition
a A scenario of adding 1600 MW of generic nuclear power upstate in 2018 was evaluated for each of the base cases This capacity addition was modeled by prorating the increase among the existing upstate nuclear facilities
b ldquoSEPB RNA Caserdquo i In addition to the 1600 MW upstate nuclear
addition this scenario also included the following capacity modifications as compared to the base ldquoSEPB RNA Caserdquo
1 Retiring of SA Carlson 27 MW in 2012
2 Retiring of Roseton 1 and 2 1144 MW in 2018
3 Shifted 20 MW of Wind Addition from 2012 to 2015
ii A NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 Retiring only one of the units result in a NYCA LOLE of 071 This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of both Roseton 1 and 2 units
c ldquoSEPB 15 x 15 Caserdquo i In addition to the 1600 MW upstate nuclear
addition this scenario also includes the following retirements as compared to the base ldquoSEPB 15 x 15 Caserdquo
1 East River Units 6 and 7314 MW in 2015
ii No LOLE violations occur through out the study period due to the low load forecast A
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 5
second case was run using the load forecast used in the ldquo SEPBRNA Caserdquo which is based on achieving only 30 of EEPS For this condition an LOLE violation of 0103 occurs in 2012 and increases to 087 in 2018
ii Scenario 2- 30 Renewable Portfolio Standard This scenario is similar to Scenario 1 with the following major differences
a Only Roseton 1 unit is retired b 3543 MW of additional wind capacity located
upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo It was found that no LOLE violations occur over the study period
IV Summary The NYISO worked closely with the SEPBrsquos Working Group to support their effort to address the future energy needs for the State NYISO shared their technical expertise provided input on the SEPB Working Grouprsquos model assumptions and commented on the results NYISO also completed a Reliability Assessment analysis in order to determine the impact of the recommended capacity modifications on the reliability of the system
Reliability Assessment Summary LOLE Results

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

D Scenario 1- Upstate Nuclear Addition A scenario of adding 1600 MW of generic nuclear power upstate in 2018 was evaluated This capacity addition was modeled by prorating the increase among the existing upstate nuclear facilities and adding the

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

I Background
By Executive Order Governor David A Paterson created the State Energy Planning Board (SEPB) in April 2008 The Governor charged the Board with analyzing a broad range of matters related to the Statersquos energy systems including but not limited to the reliability of delivery networks for electricity natural gas and petroleum products and the interrelated effects of New Yorkrsquos production and use of energy on the Statersquos economy environment and transportation systems The Governorrsquos 2009 Energy Plan (Plan) will contain policies programs and strategies that will address these matters over the 2009 through 2018 planning horizon
As part of the Energy Plan an extensive multi-part computer modeling effort was undertaken to assess the effects of policies and programs recommended for adoption on a range of factors relevant to decision-makers Among them are the cost of electricity and capacity forecasted changes in the electricity and natural gas systems including the transfer capabilities of the transmission grid and emission levels of greenhouse gases and other pollutants
The NYISO supported the Statersquos development of the computer modeling effort by providing several technical white papers and reviewing the model assumptions and results
Based on the results of the Energy Plan assessment assumptions regarding the retirement or repowering of existing generating units and the installation of new units were made by the SEPB Working Group to meet the future capacity needs of the state and the environmental objectives The NYISO performed a reliability study using the GE Multi-Area Reliability Simulation (MARS) program version 292 The Reliability Study was conducted to verify that the SEPBrsquos assumed capacity modifications would not result in the violation of the Loss of Load Expectation (LOLE) criterion of once in 10 years (or 01 per year) as established by the Northeast Power Coordinating Council (NPCC) and the New York State Reliability Council (NYSRC) That criterion establishes that the resources available on the electric system in New York should be sufficient such that the probability of an unplanned outage on the bulk power grid is never greater than once in ten years
II Integrated Planning Model Analysis To support the Statersquos Integrated Planning Model (IPM) analysis the NYISO performed the following tasks
1 Provided to the State technical white papers in October and November 2008
2 Provided forecasting and other modeling assumptions used in the development of the 2009 Reliability Needs Assessment and 2009

Installed Reserve Margin
3 Reviewed and provided comments to the SEPB Working Grouprsquos Assumption Matrix attached in Appendix A
4 Reviewed and provided comments on the SEPB Working Grouprsquos transmission topology included in Appendix B
5 Reviewed the SEPB Working Grouprsquos results from the IPM model and raised concerns regarding the fuel pricing imports and exports capacity levels environmental allowances and emission levels
6 Reviewed and provided comments on the first draft of the State Energy Planning Board preliminary assessment
III Reliability Assessment A Process
In order to assess the reliability of the capacity retirementsadditions resulting from the IPM study the NYISO modeled the SEPB Working Grouprsquos capacity recommendations in MARS and calculated the LOLE The SEPB Working Group developed two IPM base case models (Reference Cases) The first utilized the load forecast that was used in NYISO RNA study This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) and is referred to as the ldquoSEPB RNA Caserdquo The second reference case modelrsquos load forecast assumes that the full EEPS is achieved and is referred to as the ldquoSEPB 15 x 15 Caserdquo Since this case assumes a lower load forecast than the ldquoSEPB RNA Caserdquo it also assumes approximately 1500 MW less capacity The recommended capacity modifications for these two base (reference) cases are included as Exhibit C-1 in Appendix C
Four study years (2009 2012 2015 and 2018) were evaluated in MARS to determine the NYCA and Zonal LOLEs for each base case model
The following two scenarios were also evaluated for each of the two base cases
1 Addition of Nuclear Capacity Upstate 2 30 Renewable Portfolio Standard
More details regarding the development of the models for the Reliability Assessment are included in Appendix C
B Results 1 Base Models (Reference Cases)
No LOLE violations of 01 or greater occurred for all study years for both base cases provided that the assumed load forecast is
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 4
achieved However if the full 15 x 15 load forecast is not achieved an LOLE violation may occur for the ldquoSEPB 15 x 15 Caserdquo It was found that utilizing the higher load forecast from the ldquoSEPB RNA Caserdquo in the ldquoSEPB 15 x 15 Caserdquo an LOLE violation of 0102 would occur in NYCA in 2012 and would increase to 0627 by 2018
2 Scenarios i Upstate Nuclear Addition
a A scenario of adding 1600 MW of generic nuclear power upstate in 2018 was evaluated for each of the base cases This capacity addition was modeled by prorating the increase among the existing upstate nuclear facilities
b ldquoSEPB RNA Caserdquo i In addition to the 1600 MW upstate nuclear
addition this scenario also included the following capacity modifications as compared to the base ldquoSEPB RNA Caserdquo
1 Retiring of SA Carlson 27 MW in 2012
2 Retiring of Roseton 1 and 2 1144 MW in 2018
3 Shifted 20 MW of Wind Addition from 2012 to 2015
ii A NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 Retiring only one of the units result in a NYCA LOLE of 071 This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of both Roseton 1 and 2 units
c ldquoSEPB 15 x 15 Caserdquo i In addition to the 1600 MW upstate nuclear
addition this scenario also includes the following retirements as compared to the base ldquoSEPB 15 x 15 Caserdquo
1 East River Units 6 and 7314 MW in 2015
ii No LOLE violations occur through out the study period due to the low load forecast A
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 5
second case was run using the load forecast used in the ldquo SEPBRNA Caserdquo which is based on achieving only 30 of EEPS For this condition an LOLE violation of 0103 occurs in 2012 and increases to 087 in 2018
ii Scenario 2- 30 Renewable Portfolio Standard This scenario is similar to Scenario 1 with the following major differences
a Only Roseton 1 unit is retired b 3543 MW of additional wind capacity located
upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo It was found that no LOLE violations occur over the study period
IV Summary The NYISO worked closely with the SEPBrsquos Working Group to support their effort to address the future energy needs for the State NYISO shared their technical expertise provided input on the SEPB Working Grouprsquos model assumptions and commented on the results NYISO also completed a Reliability Assessment analysis in order to determine the impact of the recommended capacity modifications on the reliability of the system

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included
a Poletti 8907 MW
3 The transfer limits used in the Base Case of the 2009 RNA were included
4 All external area loads and capacity data were held constant through out the study period
B SEPB RNA Case
1 Load Forecast The ldquoSEPB RNA Caserdquo utilizes the load forecast used in the 2009 RNA Base Case This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) as shown in Table 1

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

I Background
By Executive Order Governor David A Paterson created the State Energy Planning Board (SEPB) in April 2008 The Governor charged the Board with analyzing a broad range of matters related to the Statersquos energy systems including but not limited to the reliability of delivery networks for electricity natural gas and petroleum products and the interrelated effects of New Yorkrsquos production and use of energy on the Statersquos economy environment and transportation systems The Governorrsquos 2009 Energy Plan (Plan) will contain policies programs and strategies that will address these matters over the 2009 through 2018 planning horizon
As part of the Energy Plan an extensive multi-part computer modeling effort was undertaken to assess the effects of policies and programs recommended for adoption on a range of factors relevant to decision-makers Among them are the cost of electricity and capacity forecasted changes in the electricity and natural gas systems including the transfer capabilities of the transmission grid and emission levels of greenhouse gases and other pollutants
The NYISO supported the Statersquos development of the computer modeling effort by providing several technical white papers and reviewing the model assumptions and results
Based on the results of the Energy Plan assessment assumptions regarding the retirement or repowering of existing generating units and the installation of new units were made by the SEPB Working Group to meet the future capacity needs of the state and the environmental objectives The NYISO performed a reliability study using the GE Multi-Area Reliability Simulation (MARS) program version 292 The Reliability Study was conducted to verify that the SEPBrsquos assumed capacity modifications would not result in the violation of the Loss of Load Expectation (LOLE) criterion of once in 10 years (or 01 per year) as established by the Northeast Power Coordinating Council (NPCC) and the New York State Reliability Council (NYSRC) That criterion establishes that the resources available on the electric system in New York should be sufficient such that the probability of an unplanned outage on the bulk power grid is never greater than once in ten years
II Integrated Planning Model Analysis To support the Statersquos Integrated Planning Model (IPM) analysis the NYISO performed the following tasks
1 Provided to the State technical white papers in October and November 2008
2 Provided forecasting and other modeling assumptions used in the development of the 2009 Reliability Needs Assessment and 2009

Installed Reserve Margin
3 Reviewed and provided comments to the SEPB Working Grouprsquos Assumption Matrix attached in Appendix A
4 Reviewed and provided comments on the SEPB Working Grouprsquos transmission topology included in Appendix B
5 Reviewed the SEPB Working Grouprsquos results from the IPM model and raised concerns regarding the fuel pricing imports and exports capacity levels environmental allowances and emission levels
6 Reviewed and provided comments on the first draft of the State Energy Planning Board preliminary assessment
III Reliability Assessment A Process
In order to assess the reliability of the capacity retirementsadditions resulting from the IPM study the NYISO modeled the SEPB Working Grouprsquos capacity recommendations in MARS and calculated the LOLE The SEPB Working Group developed two IPM base case models (Reference Cases) The first utilized the load forecast that was used in NYISO RNA study This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) and is referred to as the ldquoSEPB RNA Caserdquo The second reference case modelrsquos load forecast assumes that the full EEPS is achieved and is referred to as the ldquoSEPB 15 x 15 Caserdquo Since this case assumes a lower load forecast than the ldquoSEPB RNA Caserdquo it also assumes approximately 1500 MW less capacity The recommended capacity modifications for these two base (reference) cases are included as Exhibit C-1 in Appendix C
Four study years (2009 2012 2015 and 2018) were evaluated in MARS to determine the NYCA and Zonal LOLEs for each base case model
The following two scenarios were also evaluated for each of the two base cases
1 Addition of Nuclear Capacity Upstate 2 30 Renewable Portfolio Standard
More details regarding the development of the models for the Reliability Assessment are included in Appendix C
B Results 1 Base Models (Reference Cases)
No LOLE violations of 01 or greater occurred for all study years for both base cases provided that the assumed load forecast is
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 4
achieved However if the full 15 x 15 load forecast is not achieved an LOLE violation may occur for the ldquoSEPB 15 x 15 Caserdquo It was found that utilizing the higher load forecast from the ldquoSEPB RNA Caserdquo in the ldquoSEPB 15 x 15 Caserdquo an LOLE violation of 0102 would occur in NYCA in 2012 and would increase to 0627 by 2018
2 Scenarios i Upstate Nuclear Addition
a A scenario of adding 1600 MW of generic nuclear power upstate in 2018 was evaluated for each of the base cases This capacity addition was modeled by prorating the increase among the existing upstate nuclear facilities
b ldquoSEPB RNA Caserdquo i In addition to the 1600 MW upstate nuclear
addition this scenario also included the following capacity modifications as compared to the base ldquoSEPB RNA Caserdquo
1 Retiring of SA Carlson 27 MW in 2012
2 Retiring of Roseton 1 and 2 1144 MW in 2018
3 Shifted 20 MW of Wind Addition from 2012 to 2015
ii A NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 Retiring only one of the units result in a NYCA LOLE of 071 This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of both Roseton 1 and 2 units
c ldquoSEPB 15 x 15 Caserdquo i In addition to the 1600 MW upstate nuclear
addition this scenario also includes the following retirements as compared to the base ldquoSEPB 15 x 15 Caserdquo
1 East River Units 6 and 7314 MW in 2015
ii No LOLE violations occur through out the study period due to the low load forecast A
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 5
second case was run using the load forecast used in the ldquo SEPBRNA Caserdquo which is based on achieving only 30 of EEPS For this condition an LOLE violation of 0103 occurs in 2012 and increases to 087 in 2018
ii Scenario 2- 30 Renewable Portfolio Standard This scenario is similar to Scenario 1 with the following major differences
a Only Roseton 1 unit is retired b 3543 MW of additional wind capacity located
upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo It was found that no LOLE violations occur over the study period
IV Summary The NYISO worked closely with the SEPBrsquos Working Group to support their effort to address the future energy needs for the State NYISO shared their technical expertise provided input on the SEPB Working Grouprsquos model assumptions and commented on the results NYISO also completed a Reliability Assessment analysis in order to determine the impact of the recommended capacity modifications on the reliability of the system
Reliability Assessment Summary LOLE Results
SEPB RNA Case No violation SEPB 15 x 15 Case No violation if full 15 x 15 EEPS is
achieved A violation in 2012 may occur if only 30 of the EEPS is achieved
Scenario 1 Upstate Nuclear SEPB RNA Case A violation occurs in 2018 if both Roseton Units are retired No violation occurs if at least one Roseton unit remains in-service SEPB 15 x 15 Case No violation if full 15 x 15 EEPS is achieved A violation in 2012 may occur if only 30 of the EEPS is achieved
Scenario 2 30 Renewable Portfolio Standard

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included
a Poletti 8907 MW
3 The transfer limits used in the Base Case of the 2009 RNA were included
4 All external area loads and capacity data were held constant through out the study period
B SEPB RNA Case
1 Load Forecast The ldquoSEPB RNA Caserdquo utilizes the load forecast used in the 2009 RNA Base Case This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) as shown in Table 1

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

III Reliability Assessment A Process
In order to assess the reliability of the capacity retirementsadditions resulting from the IPM study the NYISO modeled the SEPB Working Grouprsquos capacity recommendations in MARS and calculated the LOLE The SEPB Working Group developed two IPM base case models (Reference Cases) The first utilized the load forecast that was used in NYISO RNA study This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) and is referred to as the ldquoSEPB RNA Caserdquo The second reference case modelrsquos load forecast assumes that the full EEPS is achieved and is referred to as the ldquoSEPB 15 x 15 Caserdquo Since this case assumes a lower load forecast than the ldquoSEPB RNA Caserdquo it also assumes approximately 1500 MW less capacity The recommended capacity modifications for these two base (reference) cases are included as Exhibit C-1 in Appendix C
Four study years (2009 2012 2015 and 2018) were evaluated in MARS to determine the NYCA and Zonal LOLEs for each base case model
The following two scenarios were also evaluated for each of the two base cases
1 Addition of Nuclear Capacity Upstate 2 30 Renewable Portfolio Standard
More details regarding the development of the models for the Reliability Assessment are included in Appendix C
B Results 1 Base Models (Reference Cases)
No LOLE violations of 01 or greater occurred for all study years for both base cases provided that the assumed load forecast is
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 4
achieved However if the full 15 x 15 load forecast is not achieved an LOLE violation may occur for the ldquoSEPB 15 x 15 Caserdquo It was found that utilizing the higher load forecast from the ldquoSEPB RNA Caserdquo in the ldquoSEPB 15 x 15 Caserdquo an LOLE violation of 0102 would occur in NYCA in 2012 and would increase to 0627 by 2018
2 Scenarios i Upstate Nuclear Addition
a A scenario of adding 1600 MW of generic nuclear power upstate in 2018 was evaluated for each of the base cases This capacity addition was modeled by prorating the increase among the existing upstate nuclear facilities
b ldquoSEPB RNA Caserdquo i In addition to the 1600 MW upstate nuclear
addition this scenario also included the following capacity modifications as compared to the base ldquoSEPB RNA Caserdquo
1 Retiring of SA Carlson 27 MW in 2012
2 Retiring of Roseton 1 and 2 1144 MW in 2018
3 Shifted 20 MW of Wind Addition from 2012 to 2015
ii A NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 Retiring only one of the units result in a NYCA LOLE of 071 This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of both Roseton 1 and 2 units
c ldquoSEPB 15 x 15 Caserdquo i In addition to the 1600 MW upstate nuclear
addition this scenario also includes the following retirements as compared to the base ldquoSEPB 15 x 15 Caserdquo
1 East River Units 6 and 7314 MW in 2015
ii No LOLE violations occur through out the study period due to the low load forecast A
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 5
second case was run using the load forecast used in the ldquo SEPBRNA Caserdquo which is based on achieving only 30 of EEPS For this condition an LOLE violation of 0103 occurs in 2012 and increases to 087 in 2018
ii Scenario 2- 30 Renewable Portfolio Standard This scenario is similar to Scenario 1 with the following major differences
a Only Roseton 1 unit is retired b 3543 MW of additional wind capacity located
upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo It was found that no LOLE violations occur over the study period
IV Summary The NYISO worked closely with the SEPBrsquos Working Group to support their effort to address the future energy needs for the State NYISO shared their technical expertise provided input on the SEPB Working Grouprsquos model assumptions and commented on the results NYISO also completed a Reliability Assessment analysis in order to determine the impact of the recommended capacity modifications on the reliability of the system
Reliability Assessment Summary LOLE Results
SEPB RNA Case No violation SEPB 15 x 15 Case No violation if full 15 x 15 EEPS is
achieved A violation in 2012 may occur if only 30 of the EEPS is achieved
Scenario 1 Upstate Nuclear SEPB RNA Case A violation occurs in 2018 if both Roseton Units are retired No violation occurs if at least one Roseton unit remains in-service SEPB 15 x 15 Case No violation if full 15 x 15 EEPS is achieved A violation in 2012 may occur if only 30 of the EEPS is achieved

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8

shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

achieved However if the full 15 x 15 load forecast is not achieved an LOLE violation may occur for the ldquoSEPB 15 x 15 Caserdquo It was found that utilizing the higher load forecast from the ldquoSEPB RNA Caserdquo in the ldquoSEPB 15 x 15 Caserdquo an LOLE violation of 0102 would occur in NYCA in 2012 and would increase to 0627 by 2018
2 Scenarios i Upstate Nuclear Addition
a A scenario of adding 1600 MW of generic nuclear power upstate in 2018 was evaluated for each of the base cases This capacity addition was modeled by prorating the increase among the existing upstate nuclear facilities
b ldquoSEPB RNA Caserdquo i In addition to the 1600 MW upstate nuclear
addition this scenario also included the following capacity modifications as compared to the base ldquoSEPB RNA Caserdquo
1 Retiring of SA Carlson 27 MW in 2012
2 Retiring of Roseton 1 and 2 1144 MW in 2018
3 Shifted 20 MW of Wind Addition from 2012 to 2015
ii A NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 Retiring only one of the units result in a NYCA LOLE of 071 This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of both Roseton 1 and 2 units
c ldquoSEPB 15 x 15 Caserdquo i In addition to the 1600 MW upstate nuclear
addition this scenario also includes the following retirements as compared to the base ldquoSEPB 15 x 15 Caserdquo
1 East River Units 6 and 7314 MW in 2015

second case was run using the load forecast used in the ldquo SEPBRNA Caserdquo which is based on achieving only 30 of EEPS For this condition an LOLE violation of 0103 occurs in 2012 and increases to 087 in 2018
ii Scenario 2- 30 Renewable Portfolio Standard This scenario is similar to Scenario 1 with the following major differences
a Only Roseton 1 unit is retired b 3543 MW of additional wind capacity located
upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo It was found that no LOLE violations occur over the study period
IV Summary The NYISO worked closely with the SEPBrsquos Working Group to support their effort to address the future energy needs for the State NYISO shared their technical expertise provided input on the SEPB Working Grouprsquos model assumptions and commented on the results NYISO also completed a Reliability Assessment analysis in order to determine the impact of the recommended capacity modifications on the reliability of the system

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included
a Poletti 8907 MW
3 The transfer limits used in the Base Case of the 2009 RNA were included
4 All external area loads and capacity data were held constant through out the study period
B SEPB RNA Case
1 Load Forecast The ldquoSEPB RNA Caserdquo utilizes the load forecast used in the 2009 RNA Base Case This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) as shown in Table 1

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

second case was run using the load forecast used in the ldquo SEPBRNA Caserdquo which is based on achieving only 30 of EEPS For this condition an LOLE violation of 0103 occurs in 2012 and increases to 087 in 2018
ii Scenario 2- 30 Renewable Portfolio Standard This scenario is similar to Scenario 1 with the following major differences
a Only Roseton 1 unit is retired b 3543 MW of additional wind capacity located
upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo It was found that no LOLE violations occur over the study period
IV Summary The NYISO worked closely with the SEPBrsquos Working Group to support their effort to address the future energy needs for the State NYISO shared their technical expertise provided input on the SEPB Working Grouprsquos model assumptions and commented on the results NYISO also completed a Reliability Assessment analysis in order to determine the impact of the recommended capacity modifications on the reliability of the system
Reliability Assessment Summary LOLE Results
SEPB RNA Case No violation SEPB 15 x 15 Case No violation if full 15 x 15 EEPS is
achieved A violation in 2012 may occur if only 30 of the EEPS is achieved
Scenario 1 Upstate Nuclear SEPB RNA Case A violation occurs in 2018 if both Roseton Units are retired No violation occurs if at least one Roseton unit remains in-service SEPB 15 x 15 Case No violation if full 15 x 15 EEPS is achieved A violation in 2012 may occur if only 30 of the EEPS is achieved
Scenario 2 30 Renewable Portfolio Standard

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included
a Poletti 8907 MW
3 The transfer limits used in the Base Case of the 2009 RNA were included
4 All external area loads and capacity data were held constant through out the study period
B SEPB RNA Case
1 Load Forecast The ldquoSEPB RNA Caserdquo utilizes the load forecast used in the 2009 RNA Base Case This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) as shown in Table 1

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included
a Poletti 8907 MW
3 The transfer limits used in the Base Case of the 2009 RNA were included
4 All external area loads and capacity data were held constant through out the study period
B SEPB RNA Case
1 Load Forecast The ldquoSEPB RNA Caserdquo utilizes the load forecast used in the 2009 RNA Base Case This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) as shown in Table 1

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012

Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included
a Poletti 8907 MW
3 The transfer limits used in the Base Case of the 2009 RNA were included
4 All external area loads and capacity data were held constant through out the study period
B SEPB RNA Case
1 Load Forecast The ldquoSEPB RNA Caserdquo utilizes the load forecast used in the 2009 RNA Base Case This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) as shown in Table 1

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included
a Poletti 8907 MW
3 The transfer limits used in the Base Case of the 2009 RNA were included
4 All external area loads and capacity data were held constant through out the study period
B SEPB RNA Case
1 Load Forecast The ldquoSEPB RNA Caserdquo utilizes the load forecast used in the 2009 RNA Base Case This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) as shown in Table 1

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included
a Poletti 8907 MW
3 The transfer limits used in the Base Case of the 2009 RNA were included
4 All external area loads and capacity data were held constant through out the study period
B SEPB RNA Case
1 Load Forecast The ldquoSEPB RNA Caserdquo utilizes the load forecast used in the 2009 RNA Base Case This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) as shown in Table 1

2 Capacity Modifications Exhibit C-1 includes the capacity modifications provided by the SEPB Working Group for inclusion in the reliability analysis The generic capacity additions shown as being located in multiple zones were entered into MARS by prorating the values across the zones based on the existing generator capacity type located in those zones The amount of generic capacity included in each zone is also shown in Exhibit C-1
Table 2 below summarizes the total capacity changes by generator type as compared to the base model for the ldquoSEPB RNA Caserdquo

II MARS Results A Base Model
For comparison purposes Table 5 below provides the LOLE results for the Base Model for each NY zone and for the overall NY Control Area (NYCA) for each study year This is based on the 2009 RNA Base Case load forecast (achieving 30 EEPS) and the capacity values

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included
a Poletti 8907 MW
3 The transfer limits used in the Base Case of the 2009 RNA were included
4 All external area loads and capacity data were held constant through out the study period
B SEPB RNA Case
1 Load Forecast The ldquoSEPB RNA Caserdquo utilizes the load forecast used in the 2009 RNA Base Case This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) as shown in Table 1

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included
a Poletti 8907 MW
3 The transfer limits used in the Base Case of the 2009 RNA were included
4 All external area loads and capacity data were held constant through out the study period
B SEPB RNA Case
1 Load Forecast The ldquoSEPB RNA Caserdquo utilizes the load forecast used in the 2009 RNA Base Case This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) as shown in Table 1

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included
a Poletti 8907 MW
3 The transfer limits used in the Base Case of the 2009 RNA were included
4 All external area loads and capacity data were held constant through out the study period
B SEPB RNA Case
1 Load Forecast The ldquoSEPB RNA Caserdquo utilizes the load forecast used in the 2009 RNA Base Case This load forecast is based on achieving 30 of the Energy Efficiency Portfolio Standard (EEPS) as shown in Table 1

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

I MARS Base Case Models A Model Assumptions
1 Study Period The Reliability Study looks out over a 10 year period from 2009 to 2018 The years studied include 2009 2012 2015 and 2018
2 Base Model A base model was created by modifying the 2009 Installed Reserve Margin (IRM) model Modifications to this one year IRM model are necessary in order to include known changes that will take place over the planning period as determined in the 2009 Reliability Needs Assessment (RNA) Base Case This base model was used as the starting point for creating the two study cases being evaluated The following modifications were made based to the 2009 Reliability Needs Assessment (RNA) Base Case
i The following generation additions and uprates which were included in the Base Case of the 2009 RNA were added
a Empire Generating (Besicorp) 660 MW b Blenheim-Gilboa Unit 1 30 MW c Blenheim-Gilboa Unit 2 30 MW d Nine Mile Point Unit 2 168 MW
ii The following generator retirements which were included in the Base Case of the 2009 RNA were included

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

B SEPB RNA Case Table 6 below provides the LOLE results for the base ldquoSEPB RNA Caserdquo The resultant LOLE criterion of 01 per year is not violated for any area for any study year Therefore the SEPB assumed capacity modifications will not negatively impact the Statersquos reliability provided that 30 of the EEPS is achieved In fact the SEPB capacity modification assumptions improves the LOLE for Zones I J and NYCA

C SEPB 15 x 15 Case Table 7 below provides the LOLE results for the base ldquoSEPB 15 x 15 Caserdquo Even though there is less capacity assumed for this case the lower load forecast is sufficient enough such that the LOLE drops as compared to the base model or the base ldquoSEPB RNA Caserdquo
However if the 15 x 15 load forecast is not achieved reliability violations may occur as early as 2012 for this given capacity condition Table 8
wwwnyisocom State Energy Planning Board Study NYISO Input and Reliability Analysis | August 11 2009 | 18
shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

A second case was run using the load forecast used in the ldquoSEPB RNA Caserdquo which is based on achieving only 30 of EEPS Table 12 includes the results of this case which shows that a NYCA LOLE violation of 0103 would occur in 2012 and increases to 087 in 2018

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

shows the results based on using the capacity assumptions for the ldquoSEPB 15 x 15 Caserdquo but only achieving the 30 of the EEPS as assumed it the ldquoSEPB RNA Caserdquo This shows that the LOLE would exceed 01 by 2012 and would exceed 06 by 2018 The primary differences impacting these LOLE results is that the ldquoSEPB 15 x 15 Caserdquo retires nearly 1000MW more and installs nearly 500MW less in fossil fuel plants than the ldquoSEPB RNA Caserdquo This will result in a much lower reliable system if the loads arenrsquot sufficiently reduced to offset this lack of generation capacity

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

1 SEPB RNA Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the following changes as compared to the base ldquoSEPB RNA Caserdquo
i Retiring of SA Carlson 27MW in 2012 ii Retiring of Roseton 1 and 2 1144MW in 2018 iii Shifted 20MW of Wind Addition from 2012 to 2015
Table 10 shows the LOLE results for the SEPB RNA Case- Upstate Scenario and indicates that a NYCA LOLE violation of 0276 would occur in 2018 An LOLE violation in Zones I and J would also occur This indicates that the addition of the nuclear capacity upstate is not sufficient to offset the retirement of the Roseton 1 and 2 units located downstate due to transmission limitations

Two additional runs were completed to determine the impact of retiring the Roseton units If both Roseton units are kept in-service the NYCA LOLE reduces to 002 If only one unit is retired the resulting NYCA LOLE would be 071
2 SEPB 15 x 15 Case- Upstate Nuclear Scenario Exhibit C-2 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis In addition to the 1600 MW upstate nuclear addition this scenario also includes the retirement of East River Units 6 and 7 (314MW) in 2015 as compared to the base ldquoSEPB 15 x 15 Caserdquo
Table 11 shows the LOLE results for the SEPB 15 x 15 Case-Upstate Scenario No LOLE violations would occur through out the study period due to the low load forecast

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

As shown in the base ldquoSEPB 15 x 15 Caserdquo if the full EEPS load forecast is not achieved a resource adequacy violation would occur The increase in the NYCA LOLE from 627 in the base ldquoSPEB 15 x 15 Caserdquo to 087 in this scenario indicates that adding 1600 MW nuclear capacity upstate is not sufficient enough to offset the retirement of the East River units located downstate
E Scenario 2- 30 Renewable Portfolio Standard Exhibit C-3 includes the capacity modifications provided by SEPB Working Group for inclusion in the reliability analysis This scenario is similar to Scenario 1 with the following major differences
i Only Roseton 1 unit is retired ii 3543 MW of additional wind capacity located upstate is included
This scenario was only run for the ldquoSEPB RNA Caserdquo As shown in Table 13 it was found that no LOLE violations would occur No further study was completed for this scenario

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period

III Summary A Base Cases
1 The capacity modifications as recommended by SEPB through out the study period for the two base cases would not result in an LOLE violation of once in 10 years provided that the corresponding load forecast is achieved However if the full energy portfolio standard load forecast is not achieved then a violation may occur in the ldquoSEPB 15 x 15 Caserdquo starting in year 2012
B Scenario Cases 1 The capacity modifications provided for the SEPB RNA Case- Upstate
Nuclear scenario would result in an LOLE violation in 2018 if both Roseton Units are retired This violation is eliminated if only one unit is retired No LOLE violation occurs for the SEPB 15 x 15 Case- Upstate Nuclear scenario if the full EEPS is achieved However a violation may occur in 2012 if the full load reduction is not achieved
2 The capacity modifications provided for the SEPB 15 x 15 Case- 30 RPS scenario resulted in no LOLE violations through out the study period
