  1. Northern California to Pacific Northwest/CanadaTransmission Line Steve Metague, PG&E February 29, 2008

  2. Project Overview This proposed line is intended to provide three main benefits. • Provides access to significant incremental renewable resources in Canada and the northwestern United States. • The proposed PNW/Canada - Northern California project will help improve regional transmission reliability. • The project will provide other market participants with beneficial opportunities to use the facilities. 7200 MW

  3. Legend: 500 kV AC AC or DC HVDC Project Overview • PG&E, along with an external project steering team, has recently completed broad stakeholder outreach and first steps of the planning process. • Project Steering team: • PG&E • Avista • PacifiCorp • Portland General Electric • British Columbia Transmission Corp • Potential Bidirectional rating: 3000 MW • Project Operating Date: late 2015 • Estimated project cost - $3-7 billion • Project Website: http://www.pge.com/mybusiness/customerservice/ nonpgeutility/electrictransmission/weccplanning Selkirk Sub Devil’s Gap Boardman Hub v Capt.
