Tri-Valley 2002 Capacity Increase Project

Welcome to the California Public Utilities Commissionís (CPUC) web site for the Tri-Valley 2002 Capacity Increase Project. Pacific Gas & Electric Company (PG&E) submitted Application Number 99-11-025 on November 22, 1999. The application requested authority to construct and operate two new substations, 13.4 miles of 230 kilovolt (kV) transmission lines, and related upgrades to existing facilities in the Cities of Dublin, Livermore, Pleasanton, and San Ramon, and in portions of unincorporated Alameda and Contra Costa Counties adjacent to these cities.

The Tri-Valley Project was approved by CPUC Decision D.01-10-029 on October 10, 2001, and construction began in September 2002. Information on construction is presented here, listing the most recent reports first. Additional information on the project is available at the other links below:
