Project Description

The Mariposa Energy Project (MEP) is located in northeastern Alameda County, approximately 7 miles northwest of Tracy, 7 miles east of Livermore, 6 miles south of Byron, and approximately 2.5 miles west of the community of Mountain House. The facility is southeast of the intersection of Bruns Road and Kelso Road on a 10-acre portion of a 158-acre parcel (known as the Lee Property) immediately south of the Pacific Gas and Electric Company Bethany Compressor Station and 230 kilovolt Kelso Substation.

MEP is a 200-megawatt (MW) natural gas-fired, simple-cycle generating facility consisting of four General Electric (GE) LM6000 PC-SPRINT combustion turbine generators and associated equipment. Linear facilities include a 580-foot natural gas pipeline and a 1.8-mile water connection with the Byron Bethany Irrigation District.

On July 30, 2015, the California Energy Commission approved a Post-Certification Amendment (TN 205635) for the installation of supplemental, temporary water storage tanks for use during a possible water curtailment. The backup temporary water supply tanks were necessary to ensure an adequate water supply to MEP if water delivery was curtailed.

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.
