TANC selects Sargent & Lundy as project engineer for transmission expansion

Chicago, IL, March 2, 2009 — The Transmission Agency of Northern California (TANC) has selected Sargent & Lundy LLC as the engineer for their planned TANC Transmission Program (TTP). The program, said the company, will enhance the reliability and power delivery capability of the Northern California transmission grid and provide increased access to local California-based renewable energy resources through a system of 230-kV and 500-kV transmission lines and substations.

There has been limited new major transmission infrastructure built in northern California since TANC placed the California-Oregon Transmission Project (COTP) in service in 1993.

TTP consists of four TANC Project segments — north, central, west, and east — and is expected to ultimately include several hundred miles of new 230kV and 500kV transmission lines, seven new substations, upgrades to over 90 miles of existing lines, and modifications to five existing substations. The range of the program covers much of the Sacramento Valley in north central California, from Ravendale to the San Francisco Bay Area.

The targeted initial in-service date is 2014.
