Transmission Agency of Northern California Transmission Project

Environmental analysis to be terminated

Western is cancelling the preparation of the environmental impact statement for the proposed Transmission Agency of Northern California Transmission Project. TANC has announced that it cannot undertake a detailed environmental analysis of the proposed project that would have involved new and upgraded 230-kV and 500-kV transmission lines, substations and related facilities in northern California.

Western is responsible for the reliable and secure operation of the Federal transmission system.  The needs to enhance reliability, relieve transmission congestion and access renewable energy resources remain.

About the TANC Transmission Project

The Transmission Agency of Northern California and Western propose to coordinate development of the proposed TANC Transmission Project, which includes new and upgraded 230-kV and 500-kV transmission lines, substations, and related facilities.  The Project would 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.

While details and plans for the proposed Project and alternatives are still being developed and refinements will continue through the public scoping process, the proposed Project would consist of five segments of transmission line corridors that generally extend from northeastern California through the Central Valley and split westward to the San Francisco Bay area and eastward to the Sierra foothills. As more information becomes available, we will post it on this site.  Check back often for updates throughout the environmental process.
