Project Objectives

Enhance access to significant incremental renewable resources in Canada and the Pacific Northwest.

Improve regional transmission reliability.

Provide market participants with beneficial opportunities to use the facilities.

Use WECC’s open stakeholder planning process.

Plan of Service Initial Plan of Service:

HVAC facilities from Selkirk-Devil’s Gap-NEO Station

HVDC facilities from NEO Station to Collinsville with possible third terminal at Cottonwood

HVAC facilities from Collinsville to Tracy Voltage support at the interconnecting

substations Remedial Actions – tripping of generation

scheduled on the project for outages of the project facilities

Project is dependent on other projects to be installed in the 2010-2015 period. Such projects: accommodate CNC Project Sponsors’ use

of CNC, or increase AC system strength to support AC

to DC conversion at the terminal stations


58

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.


59

WECC Rating Process Next Steps Phase 1 Comprehensive Progress Report (CPR)

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.



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.

Objectives and Resources

The interconnection will allow Avista access to other renewable resources in the Northwest as well as in Canada.

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.



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!
