Overview
PG&E Substation is an operational electrical substation in California, United States, owned and operated by Pacific Gas and Electric Company. It operates at voltage levels of 115 kV and 70 kV.
PG&E Substation is an electrical substation located in California, United States, owned and operated by Pacific Gas and Electric Company (PG&E). The facility is operational and serves as a key node in the regional power grid, stepping down transmission voltages for local distribution. The substation operates at voltage levels of 115 kV and 70 kV, typical for sub-transmission and distribution infrastructure in the United States. As part of PG&E's network, it is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) oversight, ensuring grid stability and compliance with mandatory reliability requirements. This facility plays a critical role in delivering electricity to communities in central California, supporting residential, commercial, and industrial loads. Its location near San Luis Obispo County positions it within a region that combines agricultural, urban, and coastal energy demands, highlighting its importance to local energy resilience.
Environmental context
The substation is situated in a region of California with a Mediterranean climate, characterized by dry summers and mild winters. The surrounding area includes both urban and agricultural land uses, with proximity to the Pacific coast. Electrical infrastructure like this substation must consider wildfire risk, a significant environmental factor in California, leading to enhanced vegetation management and grid hardening practices. The facility's voltage levels and operational status indicate it is part of the backbone transmission network, which is essential for integrating renewable energy sources such as solar and wind power common in the region.
