Overview
CPM Substation is an operational electrical substation in California, owned and operated by Pacific Gas and Electric Company. It operates at a voltage of 115 kV, serving the regional grid.
CPM Substation is an operational electrical substation located in California, United States, owned and operated by Pacific Gas and Electric Company (PG&E). The facility operates at a voltage of 115 kV, classifying it as a medium-voltage substation within the broader transmission and distribution network. As part of PG&E's infrastructure, it plays a role in delivering electricity to customers in the region. The substation's technical specifications include a voltage level of 115 kV, which is typical for sub-transmission or distribution substations that step down power from higher transmission voltages. 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) for interstate aspects. PG&E, as a major investor-owned utility, operates under the jurisdiction of the California Public Utilities Commission (CPUC) for intrastate matters. CPM Substation contributes to the stability and reliability of the local electrical grid, supporting residential, commercial, and industrial loads in the surrounding area. Its location in California, a state with a diverse energy mix including renewable sources, underscores its role in integrating and distributing power. The substation's operational status ensures continued service to the community, aligning with PG&E's commitment to safe and reliable electricity delivery.
Environmental context
The substation is situated in a region of California characterized by a Mediterranean climate with hot, dry summers and mild, wet winters. The area is prone to wildfire risks, which can impact electrical infrastructure through vegetation contact and equipment damage. PG&E has implemented enhanced vegetation management and grid hardening measures to mitigate these risks. The substation's voltage level and urban proximity influence its environmental footprint, with considerations for electromagnetic fields and land use.
