The Metcalf Energy Center (MEC), is located in southern San Jose approximately one-half mile west of the PG&E Metcalf substation. The project site is at the southern base of Tulare Hill in northern Coyote Valley of South San Jose to the west of Monterey Highway just south of the Metcalf Road intersection. The site is bordered by Fisher Creek to the north and west and the Union Pacific Railroad right-of-way to the east. Blanchard Road is to the south.
MEC is a nominal 600-megawatt combined-cycle, natural gas-fired power plant with a 230 kilovolt (kV) switchyard and approximately 200 feet of new 230 kV transmission line. Natural gas for the facility is delivered via an approximately one mile 16-inch pipeline connecting to an existing Pacific Gas & Electric (PG&E) transmission backbone pipeline that runs along the eastern side of U.S. Route 101. Recycled water for cooling is supplied by the South Bay Water Recycling Program (SBWR) and is delivered from a tap into SBWR’s existing main pipeline in eastern San Jose via a 20-inch, 7.3-mile pipeline.
On November 24, 2020, California Energy Commission staff approved the installation of additional temperature sensors, instrumentation, controls, and piping, and replacement of existing hot gas path components including turbine blades, nozzles, and associated structural elements. The equipment upgrades will reduce the turbine heat rate, generating more power from the same amount of fuel, thereby resulting in an increased output by 30 MW. The upgrades were completed in May 2021.
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.
