Infrastructure Program
To address the region’s transmission needs, BPA developed a transmission infrastructure program in 2001 to focus on: Maintaining reliable transmission service to
population centers. Restoring or enhancing transfer capability across
key paths. Providing margin so the system can be
maintained. Evaluating and investing in non-wires alternatives.
6
Infrastructure Accomplishments
First major line construction in the Northwest since 1987.
Invested more than $1 billion over four years. Two 500-kV lines completed, one under way. Modernized the nation's largest direct current
terminal (Celilo Converter - 3100 MW). Several projects to upgrade local load service.

Non Wires Solutions
Potential Measures Demand response Energy efficiency Distributed generation Appropriately sited large generation
Objectives Find least-cost solutions to transmission limitations Provide equivalent reliability to a transmission fix Benefits of transmission deferral
Time value of money Option value of delaying costly investments

Integrated Planning Concept
Objective: Achieve an adequate and least-cost plan in a functionally separated industry.
Premise: Most commitments to long-term transmission, particularly those that require expansion, are tied to utility power purchase agreements.
Concept: Establish a coordinated planning cycle that links individual utility resource planning with a region-wide transmission open season.
Benefits: Improves our ability to develop transmission when needed. Provides for a regional adequacy assessment.
