Q3 2016 Project Tracking Report 3

EXECUTIVE SUMMARY

SPP actively monitors and supports the progress of transmission expansion projects, emphasizing the importance of maintaining accountability for areas such as grid regional reliability standards, firm transmission commitments and Tariff cost recovery.

Each quarter SPP staff solicits feedback from the project owners to determine the progress of each approved transmission project. This quarterly report charts the progress of all SPP Transmission Expansion Plan (STEP) projects approved either directly by the SPP Board of Directors (Board) or through a FERC filed service agreement under the SPP Open Access Transmission Tariff (OATT).

The reporting period for this report is February 1, 2016 through April 30, 2016. Table 1 provides a summary of all projects in the current Project Tracking Portfolio (PTP), which includes all Network Upgrades in which construction activities are ongoing, or construction has completed but not all the close-out requirements have been fulfilled in accordance to Section 13 of Business Practice 7060. The PTP includes all active Network Upgrades including transmission lines, transformers, substations, and devices.

Table 1 below summarizes the PTP for this quarter. Figures 1 reflects the percentage cost of each upgrade type in the PTP. Figure 2 shows the percentage cost of each project status in the PTP.

NTC PROJECT SUMMARY

In adherence to the OATT and Business Practice 7060, SPP issues Notifications to Construct (NTCs) to Designated Transmission Owners (DTOs) to commence the construction of Network Upgrades that have been approved or endorsed by the Board intended to meet the construction needs of the STEP, OATT, or Regional Transmission Organization (RTO).

Figure 3 reflects project status within each source study, and Table 2 provides the supporting data. Figure 4 shows the amount of estimated cost by in-service year for all Network Upgrades that have been issued an NTC or NTC-C. Note: Figures 3 and 4, and Table 2 provide data for all projects for which SPP has issued an NTC or NTC-C, regardless of completion date, and therefore include data from Network Upgrades no longer included in PTP.

NTC ISSUANCE Twenty-two new NTCs were issued since the last quarterly report totaling an estimated $521.7 million.

Five NTCs were issued as a result of the completion of Aggregate Studies, SPP-2014-AG1-AFS-6 and SPP-2015-AG1-AFS-6. The total estimated cost of the Network Upgrades listed in these NTCs is $6.1 million.

NTC No. 200384 was issued to Southwestern Public Service Co. (SPS) as a result of the Delivery Point Addition Study, DPA-2013-JUN-342. The total estimated cost of the two Network Upgrades listed in this NTC is $4.6 million.

NTC No. 200385 was issued to Mid-Kansas Electric Company (MKEC) after the Board in April 2016 concluded the Transmission Owner Selection Process for the Competitive Upgrade to build a new 21-mile 115 kV line from Walkemeyer to North Liberal. The estimated cost of the Network Upgrade is $8,325,610.

Ten NTCs and three Notification to Construct with Conditions (NTC-C) were issued as a result of the Board approval of the 2016 Integrated Transmission Planning Near-Term Assessment (ITPNT). The total estimated cost of the Network Upgrades described in these NTCs is $499.5 million.

One Generation Interconnection NTC was issued to Oklahoma Gas & Electric Company (OGE) for a Network Upgrade estimated to cost $20,000.

PROJECT STATUS SUMMARY SPP assigns a project status to all Network Upgrades based on the projected in-service dates provided by the DTOs relative to the Need Date determined for the project. Project status definitions are provided below:

• Complete: Construction complete and in-service • Closed Out: Construction complete and in-service; all close-out requirements fulfilled • On Schedule < 4: On Schedule within 4-year horizon • On Schedule > 4: On Schedule beyond 4-year horizon • Delayed: Projected In-Service Date beyond Need Date; interim mitigation provided or

project may change but time permits the implementation of project • Within NTC Commitment Window: NTC/NTC-C issued, still within the 90-day written

commitment to construct window and no commitment received • Within NTC-C Project Estimate Window: Within the NTC-C Project Estimate (CPE)

window • Within RFP Response Window: RFP issued for the project • Re-evaluation: Project active; pending re-evaluation • Suspended: Project suspended; pending re-evaluation

Figure 6 reflects a summary of project status by upgrade type on a cost basis.

BALANCED PORTFOLIO

Approved in April 2009, the Balanced Portfolio was an initiative to develop a group of economic transmission upgrades that benefit the entire SPP region, and to allocate those project costs regionally. The projects that were issued NTCs as a result of the study include a diverse group of projects, estimated to add approximately 702 miles of new 345 kV transmission line to the SPP system.

The total cost estimate of $831.4 million for the projects making up the Balanced Portfolio decreased by less than 1% from the previous quarter’s total.

All the projects making up the Balanced Portfolio have been completed and placed into service. A final reallocation of Revenue Requirements for deficient Zone(s) will be performed once all actual costs have been reported.

Figure 7 below depicts a historical view of the total estimated cost of the Balanced Portfolio. Table 9 provides a project summary of the projects making up the Balanced Portfolio.

PRIORITY PROJECTS

In April 2010 the Board and Members Committee approved for construction a group of "priority" high voltage electric transmission projects estimated to bring benefits of at least $3.7 billion to the SPP region over 40 years. The projects issued NTCs as a result of the study are estimated to add 291 miles of new single circuit 345 kV transmission line and 435 miles of double circuit 345 kV transmission to the SPP region.

In October 2010 the Board approved an overall cost increase for the Priority Projects due to line rerouting and addition costs for reactive compensation. The total cost estimate for the Priority Projects after the variances were approved was $1.42 billion.

The total cost estimate of $1.32 billion for the projects included in the Priority Projects report decreased by less than 1% from the previous quarter’s total.

Figure 8 below depicts a historical view of the total estimated cost of the Priority Projects. Table 10 provides a project summary of the projects making up the Priority Projects. Table 11 lists construction status updates for the Priority Projects not yet completed.

2012 ITP10

In January 2012 the Board approved the first Integrated Transmission Planning 10-Year Assessment (ITP10). The projects approved as a part of the report ranged from comprehensive regional solutions to local reliability upgrades to address the expected reliability, economic, and policy needs of the studied 10- year horizon. The approved portfolio from the 2012 ITP10 is expected to add approximately 513 circuit miles of new 345 kV transmission.

All the projects from the 2012 ITP10 are currently in the planning or construction phases. The first 2012 ITP10 project expected to complete is the new Matthewson 345 kV substation and second 345 kV circuit from Matthewson to Cimarron projected to be energized in July 2016.

Figure 9 below depicts a historical view of the total estimated cost of the 2012 ITP10 projects. Table 12 provides a summary of the projects approved as part of the 2012 ITP10.

OUT-OF-BANDWIDTH PROJECTS

In adherence to the Business Practice 7060, SPP reports projects that have updated cost values that exceed their established baseline values based upon a ±20% bandwidth. Variances are determined by total project cost.

Two projects with a cost estimate greater than $5 million were identified as having exceeded the ±20% bandwidth requirement during the reporting period.

Table 13 provides summary information and Table 14 lists the cost detail for the out-of-bandwidth projects for Q2 2016.
