Overview
Cottonwood Substation is an operational electrical substation in California, owned and operated by Pacific Gas and Electric Company. It handles voltages of 230 kV and 115 kV, serving the regional grid.
Cottonwood Substation is an operational electrical substation located in California, United States. Owned and operated by Pacific Gas and Electric Company (PG&E), the facility plays a key role in the state's electrical infrastructure. With voltage levels of 230 kV and 115 kV, it is classified as a high-voltage substation, critical for transmitting electricity over long distances and interconnecting with the broader grid. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. PG&E, as the owner and operator, adheres to these standards to ensure grid stability and safety. The facility's dual voltage capability allows it to step down power from transmission to sub-transmission levels, serving both industrial and residential customers in the region. As part of California's extensive electrical network, Cottonwood Substation supports the integration of renewable energy sources, such as solar and wind, which are prevalent in the state. Its location in a seismically active area necessitates robust engineering to withstand earthquakes. The substation's operational status ensures reliable power delivery to communities and industries, contributing to the region's economic vitality.
Environmental context
The substation is situated in a region with a Mediterranean climate, characterized by hot, dry summers and mild, wet winters. Its location in a seismically active zone requires infrastructure designed to withstand earthquakes. The facility's role in the grid supports the integration of renewable energy, reducing reliance on fossil fuels and aiding California's clean energy goals.
