Project Description

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

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.
