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)

Submitted Regional Planning Project Report to WECC Planning
Coordination Committee and Technical Studies Subcommittee on October
30th for 30 day review.
Studies demonstrate the Project’s effectiveness during heavy load
conditions occurring either in the winter or late spring / early summer.
The east – west proposed rating was determined using a WECC 2017
Heavy Winter case, and a WECC 2015 Heavy Summer case.
Generation in the Northwest was dispatched to achieve 1,500 MW of
flow on Southern Crossing in the winter and 1,400 MW in the summer
meeting WECC Reliability Criteria.
Presented preliminary WECC Phase 1 study results to TCWG
Begun critical issues analysis work for proposed ROW

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.

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.

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!
