Overview
Henrietta 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 as a key node in the regional transmission grid.
Henrietta Substation is an operational electrical substation located in California, United States. Owned and operated by Pacific Gas and Electric Company (PG&E), the facility is part of the high-voltage transmission network, operating at 230 kV. This voltage level classifies it as a major substation, typically serving to step down power from extra-high-voltage lines for regional distribution. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. PG&E, as the owner and operator, must comply with these standards to ensure grid stability. Located in California's Central Valley, the substation supports the region's agricultural and urban electricity demands. Its role in the grid is critical for maintaining reliable power supply, especially during peak demand periods. The facility contributes to the resilience of the local electrical infrastructure, serving communities and industries in the area.
Environmental context
The substation is situated in California's Central Valley, a region with hot summers and high electricity demand for air conditioning and agricultural irrigation. The facility's 230 kV voltage level indicates its importance in the transmission grid, connecting generation sources to load centers. Its location in a rural area may reduce direct environmental impact, but the substation's operation is subject to state and federal environmental regulations, including those related to electromagnetic fields and land use.
