Goals Supporting Coordination

Develop ideas to ensure robust proposals brought to sub-regional &
regional engagement

Avoid duplication of study work and facilities constructed

Ensure efficient use of resources, siting, permitting, environmental

Regional view of transmission requirements necessary long term

NW Transmission Hub concept formulated

Optimize current expansion plans from commercial as well as technical
views

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

Plan of Service

Initial Plan of Service:
 HVAC facilities from Selkirk-Devil’s GapNEO 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

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.

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.
64
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!
