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.

On May 19, 2014, the California Energy Commission (CEC) approved a Post-Certification Amendment (PCA) (TN 202345) allow MSCC to remove to from service approximately 9,000 feet of the steam distribution system, isolating the furthest portion of the distribution system. This would allow MSCC to maintain pressure and quality throughout the distribution system at the reduced flow rates.

On May 19, 2014, the CEC approved a PCA (TN 202346) to allow the upgrade of existing Dry Low-NOx 9 (DLN9) combustion systems (Units A and B) to the latest revision DLN1+Turndown Enhance combustion systems.

On June 14, 2016, the CEC approved a PCA (TN 211855) to allow the divestiture of the remaining portion of the existing steam distribution line to Aera Energy, LLC.

Power Plant Certification and Exemption Processes

As required by the Warren-Alquist Act, the Energy Commission monitors Commission-certified energy projects throughout construction, operation, and closure to ensure compliance with the conditions of certification imposed by the Commission’s Final Decision for approving the projects.
