High-voltage substation construction and transformer work across Utah. Here is the grid ESS operates in.
Coal remains Utah's largest single electricity source at roughly 46 percent of generation, though its share has declined as plants reduced output or retired. Natural gas supplies about 33 percent, and renewables provide close to 20 percent, led by utility-scale solar with smaller amounts of wind, hydroelectric, and geothermal. The coal units at the Intermountain Power Plant near Delta stopped generating in November 2025 as the site converts to hydrogen-capable natural gas turbines.
Utah is shifting away from coal toward natural gas and rapidly growing solar, which requires new dispatchable capacity, storage, and transmission to maintain reliability. Load growth from data centers and industrial development along the Wasatch Front is increasing demand. Integrating large amounts of variable solar and connecting new generation to load centers are the state's primary transmission and distribution challenges.
Shown as regional context, the major electric utilities and grid organizations operating in Utah. ESS builds substations and installs EHV apparatus across the western grid and has mobilized wherever the work is since 1978.
