Overview
Herndon 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 230 kV, serving the regional grid.
Herndon 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 key role in the state's electrical infrastructure. The substation operates at a voltage of 230 kV, classifying it as a high-voltage transmission asset within the PG&E network. As a 230 kV substation, Herndon Substation is part of the high-voltage transmission system that interconnects power generation sources with distribution networks. In the United States, such facilities are subject to reliability standards set by the North American Electric Reliability Corporation (NERC) and regulated by the Federal Energy Regulatory Commission (FERC). PG&E, as the operator, must comply with these standards to ensure grid stability and security. The substation's location in California places it within a region with diverse energy resources, including renewable generation. Its role in stepping down voltage for local distribution or interconnecting transmission lines is critical for maintaining reliable electricity supply to surrounding communities. The operational status indicates ongoing contribution to the grid's resilience and capacity.
Environmental context
The substation is situated in California's Central Valley, a region with a Mediterranean climate and significant agricultural activity. Electrical infrastructure like Herndon Substation supports the integration of renewable energy sources, such as solar and wind, which are prevalent in the area. The facility's high-voltage operation helps minimize transmission losses, contributing to overall energy efficiency.
