Melones Substation: 115 kV Electrical Substation in California, USA

Melones 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 network. As part of PG&E's infrastructure, it plays a role in distributing electricity across the region. 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 a major investor-owned utility, adheres to these standards to ensure grid stability. The 115 kV voltage level is typical for subtransmission or distribution substations that connect local distribution networks to higher-voltage transmission lines. Environmentally, Melones Substation is situated in a rural area of California, near the foothills of the Sierra Nevada. Its operation supports the integration of renewable energy sources, such as hydropower from the nearby Melones Reservoir, and contributes to the resilience of the local grid. The substation's location in a seismically active region necessitates robust engineering to withstand earthquakes, ensuring continuous power supply to communities.
