Overview
Centennial Substation is an operational electrical substation in the United States, operating at 138 kV. It plays a key role in regional grid stability and power distribution.
Centennial Substation is an operational electrical substation located in the United States, with coordinates 40.732752, -111.989624. Operating at a voltage of 138 kV, it is classified as a transmission-level substation, which is typical for medium-scale grid infrastructure supporting urban and industrial loads. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for bulk power systems. The 138 kV voltage level is common for sub-transmission networks that connect distribution systems to higher-voltage transmission lines, facilitating efficient power flow. Centennial Substation contributes to the electrical infrastructure of the region by stepping down voltage for local distribution or interconnecting generation sources. Its operational status ensures continued support for grid stability and electricity supply to surrounding communities, aligning with sector standards for safety and reliability.
Environmental context
The substation is located in an urban or suburban area near Salt Lake City, Utah, where electrical infrastructure supports a mix of residential, commercial, and industrial demand. The 138 kV voltage level indicates moderate environmental footprint, with typical considerations for electromagnetic fields and land use. Modern substations often incorporate SF6-free switchgear and noise mitigation measures to reduce local impact.
