Alternative Intake Project Transmission Line and Interconnection

Alternative Intake Project Transmission Line and Interconnection

The Western Area Power Administration (Western) has prepared an Environmental Assessment (EA) to analyze a proposal to construct, operate, and maintain a new 3.6 mile long 69-kilovolt (kv) single circuit electrical transmission line and to provide a new interconnection to the Contra Costa Water District's (CCWD) Alternative Intake Project (AIP) located in the Sacramento-San Joaquin Delta within San Joaquin and Contra Costa Counties. Under the Proposed Action, Western would provide electric service to CCWD facilities including a new CCWD substation and pump station on the Victoria Canal. The EA evaluates Western's transmission line and interconnection (Proposed Action) for AIP. The proposed Action would extend Western's existing Tracy-Los Vaqueros 69-kV transmission line from near CCWD's existing Old River Pump Station, span Old River onto Victoria Island, and continue along existing dirt roads to the AIP's new power substation serving the new CCWD Victoria Canal Pump Station. Western would be responsible for constructing, operating, and maintaining the proposed transmission line.
