objectives29
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
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

technical study activities
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

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

objectives and resources
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 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
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.
