Project Description

The Midway Sunset Cogeneration Company (MSCC) project is located in Fellows, Kern County, California, approximately 40 miles west of Bakersfield.

MSCC is a 225-megawatt cogeneration facility that also produces steam to aid in thermally enhanced oil recovery. The facility is comprised of three GE Frame 7E combustion turbine generators (CTGs). The three CTGs were designed to produce electricity for sale to utilities and across the fence to the steam host. The steam host purchases all the steam generated by the CTGs for use in oil recovery.

Since commissioning of the project, output, oil production and, subsequently, steam demand has declined. Starting in November 2010, the steam host required steam from only two CTGs, four years later from only one CTG. Since the original steam distribution system was designed for steam output from three CTGs, steam production from one CTG was not enough to maintain the required pressure, temperature, and quality at distant injection wells.

In 2014, MSCC upgraded from Dry Low-NOx 9 (DLN9) combustion systems to DLN1+Turndown Enhanced combustion systems.

Power Plant Certification and Exemption Processes

The CEC has the exclusive authority to certify all thermal power plants 50 megawatts (MW) and larger and related facilities proposed for construction in California. The Application for Certification (AFC) process is a certified regulatory program under the California Environmental Quality Act (CEQA). As a certified regulatory program, the CEC does not prepare environmental impact reports (EIRs) in an AFC proceeding, but instead prepares environmental assessment documents that are functionally equivalent to EIRs. A certificate issued by the CEC is in lieu of any permit, certificate, or similar document otherwise required by any state, local or regional agency, or federal agency to the extent permitted by federal law, and supersedes any applicable statute, ordinance, or regulation of any state, local, or regional agency, or federal agency to the extent permitted by federal law.
