Overview
Corcoran Substation is an operational electrical substation in California, United States, owned and operated by Pacific Gas and Electric Company. It operates at a voltage of 115 kV, serving the local grid.
Corcoran Substation is an operational electrical substation located in California, United States. Owned and operated by Pacific Gas and Electric Company (PG&E), this facility plays a role in the regional transmission and distribution network. The substation operates at a voltage of 115 kV, which is typical for sub-transmission or distribution-level infrastructure in the United States. As part of PG&E's extensive grid, Corcoran Substation is subject to regulatory oversight by the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards. These standards ensure the stability and security of the bulk power system. The substation likely employs modern automation and protection systems, such as those based on IEC 61850, to enhance operational efficiency and grid resilience. The substation's location in California's Central Valley places it in a region with significant agricultural and industrial energy demand. Its role in distributing power to local communities and businesses underscores its importance to the area's economic activity. The facility's operational status and integration into PG&E's network contribute to the reliability of electricity supply in the region.
Environmental context
The substation is situated in the Central Valley of California, a region characterized by intensive agriculture and a Mediterranean climate with hot, dry summers. The facility's operation supports local energy needs, including irrigation pumping and food processing. While substations have minimal direct environmental impact, their role in grid stability is critical for integrating renewable energy sources, such as solar farms common in the area. The 115 kV voltage level indicates a distribution-level asset, which typically has lower environmental footprint compared to high-voltage transmission lines.
