Overview
Stoker Substation is an operational electrical substation in Arizona, United States, owned and operated by Salt River Project. It operates at 69 kV, serving the regional grid.
Stoker Substation is an operational electrical substation located in Arizona, United States. Owned and operated by Salt River Project, a major utility in the Southwest, this facility plays a role in the regional power distribution network. The substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level infrastructure. As part of the U.S. electrical grid, Stoker Substation operates under the regulatory framework established by the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards. These standards ensure grid stability and security. The 69 kV voltage level places this substation in a medium-voltage category, often used to distribute power from larger transmission lines to local distribution networks. The substation's location in Arizona places it within a region experiencing growing electricity demand due to population growth and economic development. Salt River Project's management ensures the facility supports reliable power delivery to residential, commercial, and industrial customers. The substation's operational status contributes to the overall resilience of the local electrical infrastructure.
Environmental context
The substation is situated in an arid desert environment typical of central Arizona, where high summer temperatures and low humidity pose challenges for electrical equipment cooling and vegetation management. The surrounding area is a mix of urban and agricultural land uses, with the substation likely supporting nearby communities and irrigation pumping. The 69 kV voltage level indicates a role in distributing power to local loads, with environmental considerations including heat dissipation and wildfire risk mitigation.
