BACKGROUND The Transmission Agency of Northern California (TANC), a California Joint Powers Agency, was formed in 1984 to assist its publicly owned members in providing cost effective energy supplies to their customers through long -term ownership of essential high voltage transmission lines within California and the Western United States. TANC's current membership includes the cities of Alameda, Biggs, Gridley, Healdsburg, Lodi, Lompoc, Palo Alto, Redding, Roseville, Santa Clara, and Ukiah; the Sacramento Municipal Utility District; the Modesto Irrigation District; and the Turlock Irrigation District. The Plumas- Sierra Rural Electric Cooperative is an associate member of TANG. TANC currently owns approximately 87 percent of the California- Oregon Transmission Project, a high voltage transmission line from the Pacific Northwest to Northern California. The Western Area Power Administration (Western), an agency within the Department of Energy (DOE), markets and delivers Federal hydroelectric power to rural electric cooperatives, municipalities, public utility districts, Federal and State agencies, Native American tribes, and irrigation districts. In addition, utilities transmitting non Federal power may buy transmission capacity on Western's system. Western owns and operates more than 17,000 miles of high voltage transmission lines. PROJECT DESCRIPTION TANC and Western propose to construct and upgrade approximately 600 miles of 230 kilovolt (kV) and 500 -kV transmission lines and associated equipment facilities in Northern California. The project is designed to provide new access to renewable energy resources in Northern California, Northwestern Nevada, and the Pacific Northwest; enhance the California- Oregon Intertie; reduce existing congestion and system losses; increase the load- carrying capability and reliability of Northern California's transmission system; improve the reliability of Western's existing Balancing Authority Area; and relieve existing electrical transmission system constraints in Northern California. The project area consists of five segments of transmission line corridors that extend from Northeastern California near Susanville, west to Redding, south to Tracy, and then southwest to Santa Clara and southeast to Turlock. A map of the preliminary proposed route is provided as Attachment 1. Pleasanton would be affected the West Segment, described below. The West Segment would include two, double- circuit, 230 -kV transmission lines from the Tracy area to Santa Clara and Newark. Maps of the proposed West Segment alignments are included as Attachment 2. The first would include adding new transmission lines to the existing transmission towers between Tracy and an existing substation in Eastern Livermore and building 30 to 40 miles of new 230 -kV transmission line from the Livermore substation to a new substation in Santa Clara. The second transmission line would follow a southwesterly path from PG &E's existing Tesla Substation east of Livermore to PG &E's existing substation in Newark. The two transmission lines would follow the same alignment just south of the existing substation Page 2 of 4
