Marsh Landing Generating Station (MLGS) is located north of the City of Antioch in Contra Costa County on a 27-acre industrial site north of Wilbur Avenue.
The project is a nominal 760-megawatt (MW) facility consisting of four combustion turbines operating in simple-cycle mode, consisting of four Siemens 5000F combustion turbine units operating in simple-cycle mode.
MLGS provides Battery Energy Storage System (BESS) and associated equipment provides an additional output of 11.5 MW and 10.5 megawatt hours, designed to start the gas turbines and to restart the power plant in the event of a grid blackout to support the California Independent System Operator’s directed restoration of the electrical grid in response to an emergency condition (also known as “black start” capability).
On March 12, 2019, the California Energy Commission approved a Post-Certification Amendment (TN 227326) to allow the installation of a battery energy storage system to provide Black Start service in response to a need identified by the California Independent System Operator.
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.
