Overview
Fair Oaks Substation is an operational 115 kV electrical substation in Sunnyvale, California, owned and operated by Pacific Gas & Electric (PG&E). It plays a key role in the regional power grid.
Fair Oaks Substation is an operational electrical substation located in Sunnyvale, California, United States. Owned and operated by Pacific Gas & Electric (PG&E), it operates at a voltage of 115 kV, classifying it as a medium-voltage substation within the broader transmission and distribution network. The facility is part of PG&E's extensive infrastructure serving the San Francisco Bay Area. The substation's 115 kV voltage level indicates its role in subtransmission or distribution, stepping down power from higher-voltage transmission lines for local distribution. As part of the US electrical grid, it operates under NERC reliability standards and FERC regulations, ensuring grid stability and compliance with mandatory reliability requirements. PG&E, as the owner and operator, adheres to these frameworks to maintain safe and reliable operations. Located in a densely populated urban area, Fair Oaks Substation supports the electrical needs of Sunnyvale and surrounding communities. Its strategic position within PG&E's network contributes to grid resilience and power delivery for residential, commercial, and industrial customers. The substation's operational status underscores its ongoing role in maintaining electricity supply in a region with high demand and technological industry presence.
Environmental context
