Overview
San Jose Substation B is an operational electrical substation owned by Pacific Gas and Electric Company in San Jose, California, operating at 115 kV.
San Jose Substation B is a key electrical substation located in San Jose, California, owned and operated by Pacific Gas and Electric Company (PG&E). The facility operates at a voltage of 115 kV, placing it in the medium-voltage range typical for distribution and sub-transmission substations serving urban and suburban areas. As part of PG&E's extensive network, it plays a role in delivering electricity to the San Jose metropolitan 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 and safety. The 115 kV voltage level is common for substations that step down power from higher transmission voltages for local distribution. San Jose Substation B contributes to the electrical infrastructure of the San Jose area, supporting residential, commercial, and industrial customers. Its urban location underscores its importance in maintaining reliable power supply to a densely populated region. The facility's operational status and integration into PG&E's grid highlight its role in the broader California electricity network.
Environmental context
Located in an urban area of San Jose, the substation's environmental context involves proximity to residential and commercial zones. Electrical substations like this one are designed to minimize environmental impact through containment of potential oil leaks and electromagnetic field management. The facility's age and technology are typical for a substation of its voltage class, with standard switchgear and transformers that meet current environmental regulations.
