Overview
Cooley Landing Substation is an operational electrical substation in California, owned and operated by Pacific Gas and Electric Company (PG&E). It operates at 115 kV, serving the local grid.
Cooley Landing Substation is an operational electrical substation located in California, United States. Owned and operated by Pacific Gas and Electric Company (PG&E), it plays a role in the regional transmission and distribution network. The substation operates at a voltage of 115 kV, which is typical for sub-transmission or distribution-level infrastructure in the US grid. As part of PG&E's network, Cooley Landing Substation is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulations. These frameworks ensure grid stability and compliance with mandatory reliability requirements. The 115 kV voltage level indicates it likely serves as a distribution substation, stepping down power from higher transmission voltages to serve local communities. The substation's location in California places it within a region with diverse energy resources and a strong focus on renewable integration. PG&E's infrastructure supports millions of customers, and substations like Cooley Landing are critical for maintaining reliable electricity supply. The facility contributes to grid resilience and supports the state's energy transition goals.
Environmental context
The substation is situated in a region with a Mediterranean climate, where seasonal variations influence energy demand. Its urban-proximate location means it supports residential and commercial loads, with potential environmental considerations related to land use and electromagnetic fields. The 115 kV voltage level is typical for distribution, and the facility's age and technology are standard for the area.
