BPA Network Open Season Update
Anders Johnson, BPA
28
Objectives

One of BPA’s most important strategic objectives is to ensure an
adequate electric power infrastructure for the Pacific Northwest

Network Open Season (NOS) is a key way to meet planning,
expansion, and reliability obligations to BPA’s Network (NT) and
Point-to-Point (PTP) customers

This project is aimed at better managing BPA’s transmission queue
and determining priorities for new transmission

BPA wants to encourage new resource development, including
development of renewable resources
29
Overview

BPA offered transmission service to all entities that requested
service on BPA’s Network (excluding interties)
 The customer committed to purchasing transmission by signing
a precedent agreement (PTSA)
 BPA’s commitment is contingent on providing service at
embedded-cost rates and completing environmental work
 BPA will perform a cluster study and commercial infrastructure
analysis

Project steering team: Avista Corp, BCTC, PacifiCorp, Portland
General, PG&E

Milestones reached:

Initiated Regional Planning 12/16/2006.
 Completed Regional Planning 11/1/2007.
 Initiated Phase 1 Rating Process 10/31/2007.
 Completed load and resources, technical feasibility and economic
screening analysis. Reports posted on project website 11/1/2007.

Milestones planned for 2008




Develop Preliminary Plan of Service – August-September 2008.
Complete Phase 1 Studies – September 2008.
Begin Phase 2 Studies (following PCC/TSS acceptance of Phase 1
Studies) – expected by November-December 2008.
Continue to perform pre-permitting studies including environmental and
design activities – throughout 2008-2009.
52
Technical Study Activities

Developed 2015 heavy summer case and 2017 heavy winter benchmark
and project base cases and shared the data with TCWG members.

Developed two and three terminal HVDC models for power flow and
dynamic studies and shared the information with TCWG members.

Developed wind generator model for power flow and dynamic studies.

Working with TCWG members reviewed project interconnection alternatives
in Oregon:
 Boardman HVDC alternative
 Olallie HVDC alternative
 Southern Oregon Hub alternative
 Station K alternative – development in progress

Completed preliminary power flow studies and shared the information with
TCWG members for review and comment.

September 2008 – Issue draft Phase 1 report including preliminary plan of
service.
53
Preliminary Findings

Preliminary findings suggest that desired rating of 3000 MW (north-south) is
feasible for all segments of the project from Selkirk-BC to Northern
California terminal at Collinsville

Among the interconnection alternatives evaluated in the technical studies,
the Southern Oregon Hub alternative had more adverse impact on the
existing PACI intertie requiring mitigation measures at added cost.

Based on preliminary technical studies, routing studies and considerations
for regional benefits, the preliminary plan of service includes:
 500 kV AC from Selkirk to the Olallie area via Devils Gap and the
Boardman Hub
 500 kV HVDC from the Olallie area termination to Collinsville area
substation in Northern California
 A potential third terminal in the Cottonwood area of Northern
California
 500 kV AC from Collinsville to Tesla/Tracy


The Avista interconnection to the PG&E Canada to Northern California 500
kV Project will provide up to 500 MW of access to the “Main Stem” Project
from the Avista transmission system for renewable resources in the Avista
service territory.

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 resources are wind resources located in various locations on the
Avista system, including but not limited to wind farms near Spokane,
Othello, Lewiston, and Clarkston Washington, as well as Grangeville, Idaho.
Avista presently has 12 interconnection requests pending.
58
Background, Study Work, and Future Meetings:

Avista announced a Regional Planning Process that will run concurrently
with a WECC Phase I Rating Process. The letter announcing these
processes went to the WECC Committees and other stakeholders in the
fourth quarter of 2007.

Preliminary studies that have been run on this project indicate that a
500/230 kV interconnection at Devils Gap with the associated 230 kV
construction is feasible. The studies further indicate that a phase shift angle
of plus 20 degrees to minus 40 degrees will be sufficient to satisfy the goal
of a bi-directional rating of 500 MW. There may be a requirement to trip the
interconnection and some generation for some outages. Studies continue.

Avista hosted an initial meeting in Spokane on 2-29-08, and will be hosting
a second meeting in the near future to review the first draft of our study
report.
