Background
Purpose: status update for several proposed projects significant to Northwest
All projects currently in or will be in WECC Phase 1 Rating Process
Began January 2008 with Transmission Coordinated Work Group (TCWG)
Goal is submission of Phase 1 reports in Q4
Sponsors are reasonably on schedule
Each project sponsor will be submitting an individual Project Phase 1 Rating report to WECC
Expectations are that projects enter Phase 2 relatively close together in the fourth quarter of 2008 or Q1 2009

Coordination A number of project sponsors are planning construction in the Northwest
in the 2010-2015 period and the study work is being coordinated. Their projects have the following characteristics: Currently in (or soon to be in) WECC Phase 1 Rating process Planning to submit their Comprehensive Progress Reports in 4Q, 2008 and
1Q, 2009 Agree to use a common study methodology
Projects that meet such characteristics include: Walla Walla-McNary (PacifiCorp) Hemingway-Captain Jack (PacifiCorp) West of McNary Project (BPA) I-5 Corridor Reinforcement BPA) Idaho-Northwest Project (Idaho Power and Others) Southern Crossing Project (PGE) Canada-Northwest-California (CNC) Project (PG&E and Others) CNC Project - Devil’s Gap Interconnection (Avista) Dry Creek-Coyote (Avista) Northern Lights Project (TransCanada) West Coast Cable (Sea Breeze)
The project sponsors have formed the Transmission Coordination Work Group (TCWG).

WECC Phase 1 Rating Process Update
Regional Planning Report completed and submitted – November 2007.
WECC Phase 1 has been coordinated with the Transmission Coordination Work Group (TCWG).
Three generation scenarios were developed to support delivery of 3000 MW of renewable resources in British Columbia, the Pacific Northwest, or Northern California/Nevada:
3000 MW of renewable generation from BC CNC project loaded to 3000 MW south of Selkirk
1500 MW of renewable generation from both BC and the Pacific Northwest CNC project loaded to 3000 MW south of the NEO Station
1500 MW of renewable generation from both BC and Northern California/Nevada CNC project loaded to 3000 MW south of the Cottonwood Area Substation.
2015 Heavy Summer base case has been used modeling the system with and without the CNC Project.
The WECC Phase I rating studies conducted to establish a north-to-south rating show: The initial Plan of Service is viable. Rating for the project segments is 3000 MW, N-S. Other proposed projects at Neo Station needed to support the HVDC terminal. Other proposed projects at Cottonwood needed to support the potential HVDC terminal. Generation tripping of power scheduled on CNC (up to 3000 MW) is required for CNC
facility outages.

WECC Rating Process Next Steps Phase 1 Comprehensive Progress Report (CPR)
Project Sponsors to e-mail the draft to Stakeholders for comment by12/1/2008.
Stakeholders include TCWG members and Big Tent attendees who request a draft copy.
Stakeholder comments requested by 12/10/2008. Final CPR and request to move to Phase 2 will be submitted to WECC by
12/16/2008.
Project sponsors are scheduled to initiate the WECC Phase 1 rating process to establish a south-to-north rating in January 2009 Studies will be coordinated through the TCWG.
Project sponsors expect to initiate the WECC Phase 2 rating process 60-days after submitting the Phase 1 CPR to WECC (mid-February).
Entities wanting to participate in the WECC Phase 1 (S-N) or Phase 2 (N-S) process should join the TCWG through the Northwest Power Pool website: http://www.nwpp.org/tcwg/ Please copy Ben Morris at [email protected]

Objectives and Resources
The Avista interconnection to the PG&E Canada to Northern California 500 kV Project will provide up to 500 MW of access from the “Main Stem” Project to the Avista transmission system, providing access to renewable resources in the Northwest and Canada.
The interconnection will also provide access to the “Main Stem” 500 kV Project for resources, including renewables, located within the Avista service territory.
The project may also allow Avista to integrate some of its existing thermal resources to its loads over its own transmission, and may allow for additional imports of economy energy into the Avista system.
Potential wind resources that may require export capacity from various locations on the Avista system include, but are not limited to, wind farms near Spokane, Othello and Clarkston, Washington, as well as Grangeville and Lewiston, Idaho. Avista presently has 10 pending interconnections.
Order 2004 Sensitive
Project Update (since July, 2008)
Avista has completed the technical study work to support the WECC Regional Planning / WECC Phase I Rating submittal as projected in July. The studies indicate that the interconnection is feasible and that there are no adverse impacts to neighboring systems from this interconnection.
Avista anticipated a joint Regional Planning / Phase I submittal for the study work, and a first draft of this report was provided to the TCWG at its October 23, 2008 meeting in Portland, Oregon. TCWG recommended that the draft report be split into two submittals. Avista has incorporated comments received at the TCWG meeting into the Regional Planning Report and has submitted that report to WECC. Comments on the report are due December 12, 2008. The Phase I report should be submitted to WECC within the next six weeks.
Avista is also working with other PG&E Project Teams (Permitting and Public Affairs) for the PG&E Canada to California project.

Project Update (since July, 2008)
Avista has begun the technical study work to support the WECC Regional Planning and WECC Phase I Rating submittals. The studies that have been completed indicate that the interconnection is feasible and that there are no adverse impacts to neighboring systems from this interconnection. The project may require phase shifting transformers as well as series compensation. The project may, at a future date, also interconnect at the NEO Station.
Avista has formally approached PacifiCorp to see if this project and the PacifiCorp Walla Walla – McNary (NEO) project might be able to utilize a common right-of-way or common transmission structures, and the two companies are now engaged in such discussions.
Avista will be hosting a kickoff meeting for the WECC Regional Planning and Phase I Study efforts for this project in the near future. Please stay tuned!
