Project Description

The Watson Cogeneration Plant is located on 21.7 acres adjacent to the Tesoro Carson Refinery in the city of Carson, Los Angeles County. The project area is zoned Heavy Manufacturing and is surrounded by existing refineries and other industrial facilities. Process steam is provided to the adjacent Refinery.

WCP is a 385-megawatt (MW) combined-cycle, cogeneration facility consisting of four parallel combustion gas turbine generators /heat recovery steam generator trains, two parallel steam turbine-driven power generator trains, associated auxiliaries and utilities, a control room, an electrical substation and a transmission line.

The electrical power generated in the WCP is sold to the Southern California Edison (SCE) Company via a high voltage transmission line connecting the VCP with the SCE Hinson Substation.

On April 11, 2012, the California Energy Commission approved an Application for Certification (09-AFC-01C) to add a 5th train to the existing project, the Watson Cogeneration Steam and Electric Reliability Project; however, the project was officially terminated by the Energy Commission on July 8, 2015 at the owner’s request.
