The proposed transmission line is a 230 kV three-phase AC line running from north of Lethbridge, Alberta, to Great Falls, Montana. In Alberta, the line will be connected to the existing 240 kV line (923L) through a new substation Picture Butte 120S located 15 km northeast of the existing North Lethbridge 370S substation. In addition to the substation connection facilities the substation will also contain a 240/230kV phase-shifting transformer to control the amount and direction of power flowing on the line. From the proposed substation, the transmission line will head east and south before leaving Alberta and entering Montana. The line will continue southward through Montana to a new mid point station, Marias Substation, and then on to Great Falls. At Great Falls, the line will connect to an existing NorthWestern Energy (NWE) substation.

The MATL project will have a normal rating of 300 MW. The line will be operated by the AESO in Alberta and by NWE in Montana.

The project has received approval the Alberta Utilities Commission (AUC), National Energy Board (NEB) as well as other responsible Federal, Provincial authorities.

North South Transmission Reinforcement – P737

500 4/2015 1 This project consists of two 1000 MW 500 kV line-commutated HVDC lines to alleviate transmission congestion along the SOK cut-plane. These two transmission lines are mandated by the Alberta

Legislature as a Critical Transmission Infrastructure (CTI) project in the Electric Status Amendment Act, 2009. The need for this line was re-affirmed by the Minister of Energy in February 2012. East Alberta Tie-Line (EATL) connects the Heartland 500 kV substation in the Fort Saskatchewan Area to the new Newell 240 kV substation in the Brooks Area. It will be built as bi-pole line with 1000 MW monopole converters using remaining conductor as metallic return. The project was approved by the Alberta Utilities Commission on November 15, 2012.

West Alberta Tie-Line (WATL) connects from new Sunnybrook substation near Genesee substation in the Wabamun Area to Langdon substation which is also the

terminal of 1201L 500kV BC-Alberta Tie-line. It will be built as bi-pole line with 1000 MW mono-pole converters using remaining conductor as metallic return. The project was approved by the Alberta Utilities Commission on December 6, 2012.

The addition of these two HVDC lines will significantly increase the North to South transfer capability (SOK limit) within Alberta. As the 1201L 500 kV Alberta to BC export capability is limited by the SOK limit, the addition of these two lines will increase the Total Transfer Capability of 1201L.

This impact will be quantified by Inter-Tie Rating Studies and HVDC OperationsStudies scheduled to be completed by the end of 2014.

The estimated ISD of WATL is April 2015 and ISD of EATL is December 2014.

Lower Valley Area Reinforcement Project

345/138/115 2016 1 A 345/161-kV transformer at PacifiCorp’s (PAC) Goshen Substation currently serves the Lower Valley area. Three transmission lines serve load out of Goshen. The Goshen-Drummond 161-kV line serves mostly Fall River loads and provides back-up service to Lower Valley. The Goshen- Swan Valley 161-kV line serves most of the Lower Valley load. The Goshen-Palisades 115-kV line serves the Palisades Generating Plant and some Lower Valley load.BPA constructed a second Swan Valley-Teton line in 2000 and upgraded the Goshen-Drummond line to 161-kV in 2002. These upgrades increased the reliability of the Fall River system and helped support load growth in the Jackson Hole area, but did not increase the transmission capability to the southern part of Lower Valley’s system. Capacitor banks have been installed at Targhee, Tincup, Teton, and Madison.PAC has constructed a new 345/138-kV Three Mile Knoll Substation a couple of miles north of their existing Caribou switching station. This new substation includes a new 345-kV interconnection with Idaho Power. Idaho Power’s Bridger-Goshen 345-kV line is looped into the new Three Mile Knoll 345/138-kV Substation which includes two new 345/138-kV, 650 MVA transformers. For the Lower Valley Area reinforcement Project, BPA will construct Hooper Springs 200 MVA 138/115-kV Substation adjacent to PAC's Three Mile Knoll Substation.

Raver 500/230 kV Transformer

500/230 2016 1 This purpose of this project is to improve load service reliability to the Puget Sound area and Northern Intertie. The Puget Sound and Northern Intertie (PSANI) area transmission system is a winter peaking system that primarily consists of the interconnected systems of BPA, Puget Sound Energy (PSE), Seattle City Light (SCL), Snohomish PUD (SPUD), Tacoma Power Utilities (TPU), and British Columbia Transmission Company (BCTC), which serve Seattle, Tacoma, Olympia, and surrounding areas.The Puget Sound Area is a highly congested network due to large concentrations of load and varying local generation patterns, which are further stressed by transfer levels between the US and Canada on the Northern Intertie. Winter peak loads are typically the worst, combined with lower local generation patterns and high exports to Canada. Through a joint Columbia Grid study effort, several system fixes have been agreed to by BPA, SCL, and PSE. They include several 115kV and 230kV PSE and SCL line upgrades, a BPA RAS upgrade and a new BPA 500/230kV transformer. The PSANI Reinforcements projects are scheduled to be completed in full by fall 2018. The Raver 500/230kV transformer addition is scheduled for completion in fall 2016.The most limiting outage for the South Puget Sound area is a common corridor N-2 Tacoma- Raver #2 and Raver-Covington #1, which results in loss of two 500/230kV banks in the area. Other N-2 common corridor outages result in a loss of two 500/230kV banks either at Tacoma, Covington, or Maple Valley substations and cause severe loading on the remaining transformer banks. Once the Raver 500/230kV transformer addition is completed, the severity of these N-2 outages will be greatly reduced, mitigating overloads, and resulting in greater reliability to load service and operational flexibility for the Southern Puget Sound Area. The project also helps to reduce the risk of curtailment or redispatch events in the Puget Sound Area for certain outage conditions.The plan of service is to install a 1300 MVA transformer at Raver substation. A new 230kV substation will be developed adjacent to the existing 500kV substation. The high side of the new transformer will terminate at Raver 500 KV. The Tacoma-Raver

#1 and #2 500 KV lines are currently jumpered together and operated as double circuit 500kV for about 10 miles from Raver until it reaches Covington substation. The corridor for both circuits runs adjacent to Covington 230kV station and in the same corridor as the Raver-Covington #1 and #2 500 KV circuits. The project will reconfigure the Tacoma-Raver 500 KV lines by removing jumpers and reterminating the Tacoma-Raver #2 circuit into Covington 230 KV and Raver 230 KV Substations. The Tacoma-Raver #2 line will be renamed and operated as the Raver-Covington #3 230 KV line. The plan of service also requires reconfiguring the Covington 230 KV bus, adding a new sectionalizing breaker and 2 bus tie breakers.

.5 3800 MW The Pacific DC Intertie (PDCI) provides a direct current (DC) intertie between The Dalles Oregon, and Los Angeles, CA. The current PDCI is rated at 3100 MW.

The PDCI Uprate project would increase the capacity by 700 MW from 3100 MW to 3800 MW. This project replaces the convertors at the Celilo HVDC terminal and re-conductors a small section of the DC transmission line. To reach the full 3800 MW will require the southern partner (LA Department of Water and Power) will need to reinforce the AC system on the southern end, upgrade some DC line sections, and make minor changes to their terminal equipment.

Montana to Washington 500 2018 .5 In 2010, Bonneville Power Administration (BPA) conducted a Network Open Season (NOS) to determine projects needed for requests for long-term firm transmission service. During the NOS process, entities requested the use of BPA's transmission system to transmit their power.

The studies found that there was not enough available transmission capacity to accommodate all requests for long-term service from BPA's Garrison Substation in Western Montana to load centers west of the Cascades and to market hubs serving the entire Northwest power market. Wind generation facilities built and proposed in the region have greatly increased the amount of planned generation in Montana seeking load and markets in the Northwest. As a result, BPA is proposing several reinforcements on BPA's transmission system at Garrison, Hot Springs, Bell, Dworshak, and Hatwai Substations.

Additionally, reconductoring is being proposed totaling 12 miles on the Dworshak-Taft No. 1 500-kilovolt (kV) line and a new series compensation substation is being proposed along the Garrison-Taft No. 1 and No. 2 500-kV lines, both of which would allow BPA to accommodate the requests for transmission service in this area. These reinforcements would increase the firm east-to-west transfer capability of the West of Garrison and West of Hatwai paths by primarily increasing the series compensation in existing 500-kV lines in the area.

Gateway West Transmission Project

500/230 2020-2024 6 The Gateway West project was jointly announced by Idaho Power and PacifiCorp (Rocky Mountain Power) in May 2007, to build and operate approximately 900 miles of new high-voltage transmission lines between the Windstar substation near Glenrock, Wyoming and the Hemingway substation near Melba, Idaho. The Gateway West – Stage 1 project will include approximately 150 miles of 230 kilovolt (kV) lines in Wyoming and approximately 800 miles of 500 kV lines in Wyoming and Idaho. Gateway West– Stage 2 transmission facilities primarily consist of a second set of 500 kV circuits from southern Wyoming to western Idaho.PacifiCorp reported in the 2011 Annual Progress Report submission that the third party requests and financial commitments that are necessary to support the Energy Gateway – Stage 2 facilities have not materialized. Therefore, PacifiCorp indicated that it would continue to pursue WECC path ratings for Stage 1 of Energy Gateway only at that time, and will not further pursue ratings for Stage 2 facilities. This Energy Gateway Project status update was also reported to TSS at the April 20-22, 2011, meeting in Westminster, Co.For Gateway West – Stage 1 transmission paths located west of Populus [specifically Borah West and Midpoint West], Idaho Power was the project sponsor for each of the path ratings studied; additionally for Gateway West transmission paths located east of Populus [specifically TOT 4A, Aeolus West, Path C and Bridger/Anticline West], PacifiCorp was the project sponsor for the path ratings studied. At the completion of the Phase 2 path rating process, TOT 4A transmission path was granted Phase 3 status on December 13, 2010; Aeolus West, Bridger/Anticline West and Path C transmission paths were granted Phase 3 status on January 5, 2011; and Borah West and Midpoint West transmission paths were granted Phase 3 status on July 21, 2011.Both the Gateway West and Gateway South siting and permitting requirements are currently being reviewed separately under the National Environmental Policy Act (NEPA) process. Future changes to the Energy Gateway Project facilities and configuration may be influenced by the NEPA process and permitting requirements until this process concludes, which today expected to conclude for Gateway West in 2013 and for Gateway South in 2015. At the conclusion of the NEPA process, specific path rating performance issues relative to any necessary changes in Energy Gateway Project facilities and configuration will be addressed with affected Project Review Groups – rather than approach the group with “piece wise” changes, at the time each change becomes known throughout the NEPA process.Based on the agreement between PacifiCorp and Idaho Power, executed in early 2012, PacifiCorp will assume responsibility for sponsoring all Gateway West transmission facilities through the NEPA process and through the project construction agreement phase.

substation near Richfield, Utah to the Red Butte substation in southwestern Utah. PacifiCorp is leading the planning effort and managing the WECC rating process for the project. The Gateway South project entered Phase 2 in January 2009. Of the transmission paths associated with the project, the Aeolus South path was granted Phase 3 status on December 16, 2010 while the TOT 2B/2C Paths should be granted Phase 3 status in the first quarter of 2011. PacifiCorp is proposing this transmission project because of native load growth and the need to deliver renewable resources from Wyoming to PacifiCorp retail load centers. PacifiCorp forecasts that its load on the Wasatch Front of Utah will double in the next 20 years. Additionally, PacifiCorp has an independent obligation, pursuant to its Open Access Transmission Tariff, to plan for and expand its transmission system based upon the needs of its native load and network customers along with eligible customers that agree to expand the transmission system.

Chinook Project +/- 500 kV DC 2017 .1 3000 MW 1 Chinook is a 500 kV, direct current, 3000 MW transmission line from south-central Montana to the Eldorado Valley in southern Nevada with a potential future 750 MW intermediate converter station near the Borah substation in south-eastern Idaho. The Regional Planning process was complete in November 2009. TransCanada conducted an Open Season for the Chinook project that closed on December 16, 2010. Bids totaling 1500 MW were received; however they were not accepted as the amount was insufficient to justify allocating capacity at this time. TransCanada may decide to hold a new open season process, if regulatory uncertainties get resolved and if Montana energy project developers express sufficient interest in a new open season. It is not unusual for projects of this scale to test the market a number of times. The fact that a project is not successful in one open season does not mean that a project is dead and, indeed, other transmission projects in the west have had multiple open seasons. The project cost is $3 billion with an ISD of 2017.

Havre to Rainbow 161kV Rebuild / Upgrade

161 2022 .75 This project is on-hold status due to high priority oil load growth. Western’s 103 mile Havre – Verona – Rainbow 161kV transmission line was constructed and energized in 1935. It electrically parallels NorthWestern Energy’s (NWE’s) Havre – Rainbow 161kV circuit. These two circuits maintain separate rights-of-ways with two crossings. Western intends to rebuild its circuit in segments, at 230kV specification. Each segment is anticipated to be complete and re-energized in approximately one month. The existing right-of-way is inadequate and will be expanded in most areas and re-

routed in others. An Environmental Assessment (EA) is complete for this project and has been issued for final publication. The first 30 mile segment between Havre and Verona is complete, along with 1 mile at the Rainbow / Great Falls end for re-termination into NorthWestern Energy’s (NWE's) Great Falls Substation in conjunction with Project 2) described below. In 2011, 14 miles of reroute and reconstruction began in the Loma, MT area and was approximately one-third complete when crews were re-dispatched due to storm damage in Eastern Montana / Western North Dakota (East Grid WAUE BA). Due to both storm damage and dramatic oil exploration load growth in the Eastern Montana / Western North Dakota area, this project has been placed on-hold for approximately 5 years, with approximately 5 years of construction remaining prior to completion. Therefore, target completion is estimated to be 2022. Once the project resumes, construction will again continue during non-peak loading periods only. Upon completion of each segment, the line will continue to be energized at 161kV until such time that conversion to 230kV is required. Additional system impact study analyses will be required with stakeholder approval prior to the 230kV voltage conversion. No interruption of customer service during construction is anticipated with this project. The project will receive a single 1 mile reroute this summer, near Carter, to raise the highway crossing for accommodation of extra large/tall shipments of pre-fabricated tanks North of Great Falls, MT.

Havre Substation Upgrade 161/115/12.47 Fall/ 2014 .2 Western currently owns, operates and maintains the Havre 161/115/12.47kV Substation. Upgrades are a result of needed relaying replacements and a new 115 kV interconnect for network load.

Laramie River Station 345/230 kV Transformer #2

345/230 8/2014 600 MVA This project consists of the addition of a second 345/230kV 600MVA transformer at the Laramie River Station (LRS) switchyard in southeast Wyoming. It will connect to the existing 345kV and 230kV buses within the LRS switchyard. The in service date is August 2014. The transformer will be owned by the Missouri Basin Power Project (MBPP). This transformer will primarily function as an in service spare unit for the MBPP. No increase in system intact path ratings is expected; therefore the WECC path rating process is not necessary. Prior outage limits on the TOT3 path and LRS generation limits may be increased as determined by future operating studies. Under some conditions a LRS generation prior outage can contribute to TOT3 limits due to overload of the existing transformer. Also prior outage of elements of the LRS 345kV transmission system can cause LRS generation limitations due to overload of the existing transformer. The second transformer will improve system capacity in these situations.

to Existing Nixon-Kelker (NX-KE) Line

b) Currently, there is only one transmission line from the CSU-owned Front Range Power Plant that generates 460 MW at summer peak. The purpose of this project is to provide a second line out of the plant to connect with an existing CSU transmission line.c) The termination point for the existing 230kV NX-KE line will be removed from the Nixon 230kV bus and the line will be re-routed into the Front Range Power Plant substation which it is only a few hundred feet from the existing line. Rather than two identical NX-KE lines, CSU will now have one 230kV line from Nixon to Kelker and one 230kV line from Front Range Power Plant to Kelker.d) The expected date of release to operations is December 2015.e) The expected operating voltage is 230kV.f) The project is not expected to have a significant impact on the operation of the WECC interconnected electric system because CSU is a small, relatively self-contained system. Changing the termination point of this existing 230kV line has very little impact on the CSU system and even less impact on the WECC system. The project provides a reliability improvement for CSU under certain Category C or D outages.

San Luis Valley-Calumet-Comanche Transmission Project

230/345 After 2015

.4 1000-1500 MW

The project consists of two basic sections and is a joint project with Xcel Energy. The first section consists of approximately ninety‐five (95) miles of new, double‐circuit 230 kV transmission, built from the San Luis Valley Substation to a new Calumet Substation, which would be located approximately six (6) miles north of the existing Tri‐State Walsenburg Substation. The second section consists of approximately forty‐five (45) miles of 19 new double‐circuit 345 kV transmission line from Calumet Substation to the existing Comanche Station near Pueblo. The project will improve local system performance and reliability, and will facilitate potential generation as part of Xcel Energy’s response to Colorado Senate Bill 07-100 which calls for development of transmission facilities to deliver power from renewable resource zones in Colorado. The project was initially planned to be in service in 2015. However, the project in service date has been delayed and will be determined after Colorado PUC and other stake holder input. This project is not expected to impose any significant impacts on the reliability of the WECC interconnected system.

system owned by Xcel Energy to deliver power to Tri-State’s loads in the PSCo Balancing Authority area. Since Tri-State has load in both the PSCo Balancing Authority area and the WACM Balancing Authority area, Tri-State desires the flexibility to directly deliver the output of the J.M. Shafer station to either Balancing Authority. Tri-State can do so by interconnecting the J.M. Shafer station directly to the Greenhouse Substation and constructing a Greenhouse to Henry Lake 230 kV line. Tri-State forecasts an increasing need for additional balancing resources in the WACM BA to comply with the State of Colorado’s Renewal Portfolio Standards. The J.M. Shafer to Greenhouse to Henry Lake230kV project will permit Tri-State to utilize the J.M. Shafer station as a balancing resource in the WACM BA. The project will also improve transmission reliability by providing a second transmission source directly to the J.M. Shafer station and mitigates the problem of losing the entire station for a single line outage.

North Gila-Imperial Valley #2 500 kV Project

500 Q3/2018 8 1 2The 85 mile NG-IV #2 500kV project is a major intertie expansion between the North Gila area (southwest Arizona) and the Imperial Valley area (southern California); this line would parallel the existing North Gila-Imperial Valley line (also known as the Southwest Power Link, or SWPL), with an expected separation of 250 feet from the existing SWPL. The potential for a second circuit would be proposed to be constructed on the same set of structures, and would potentially loop in and out of the existing Highline 230 kV substation along the Highline Canal. The second circuit could be operated at 230kV initially until the operational and scheduling need develops over the years to potentially operate at 500kV. An additional alternative that we have been asked to review by the PCRG is to have a single 500kV line and with the loop-in to the existing Highline 230kV station. Review is currently underway of this configuration.

Gates – Gregg 230kV Line Project

230 12/2022 .5 This project is to construct a 68 mile long 230kV DCTL from Gates to Gregg with one side strung. This project will improve reliability in the Greater Fresno area, allow greater operational flexibility of the three units at the Helms Pumped Storage Plant (PSP), and help integrate renewable resources within California. Since the proposed Gates – Gregg 230kV line will be in parallel with the existing Gates – Gregg 230kV line that is one of the Path 15 lines, this project will trigger re-definition of Path 15.In the 2012/13 Transmission Plan Process, the CAISO recommended and approved the Gates - Gregg 230kV transmission line, constructed as a double circuit line. One of the circuits is to be strung initially (by 2022 or earlier), and the other will be strung in the future after demand has increased sufficiently (anticipated in the 2025-2027 timeframe).In June 2013, the consortium of PG&E, MidAmerican Transmission and Citizens Energy submitted a bid to CAISO for the Gates-Gregg 230kV transmission line and was awarded the project in November 2013.
