Creelman Substation is an operational electrical substation located in San Diego County, California, United States. Owned and operated by San Diego Gas & Electric (SDG&E), it operates at a voltage level of 69 kV, classifying it as a sub-transmission or distribution substation within the regional power grid. As part of SDG&E's network, the substation is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulation for transmission-level assets. The 69 kV voltage level is typical for distribution substations that step down power from higher transmission voltages to serve local communities and industrial customers. The substation plays a role in maintaining grid stability and reliability for the surrounding area. Its operational status ensures continued electricity supply to residential, commercial, and industrial users in the region, supporting San Diego County's energy needs.
Environmental context
The substation is located in a semi-arid region of Southern California, where wildfire risk is a significant environmental concern for electrical infrastructure.
