CA Central Valley Transmission Expansion to Begin

LCG, September 16, 2003Energy officials announced that $330 million has been provided for electricity transmission expansion along a California bottleneck.

Pacific Gas & Electric Company (PG&E), Trans-Elect, and the Western Area Power Administration (WAPA) have formed a public-private partnership to construct the transmission upgrade, which will expand Path 15, an 84-mile, high-voltage line in Californias Central Valley.

PG&E has agreed to pay for improving interconnections to add the new line to existing infrastructure. Trans-Elect will own 72 percent of transmission rights on the new line, and WAPA will own and maintain the lines.

The project was contracted for $87.8 million to Arizona-based Maslonka & Associates.

Path 15 consists of three 500-kV lines between Northern and Southern California. However, between Los Banos and Gates substations, only two lines were constructed. A third line will add 1,500 megawatts of transmission capacity.

The California Independent System Operator voted to upgrade path 15 in June 2002 and expects the improved transmission to save Californians between $100 and $300 million per year.
