Utah's generating fleet in context
Utah's installed generating capacity stands at 12.3 GW across 133 plants, ranking 37th of the 50 states and DC. Natural gas provides 33% of the state's capacity with 4,052 MW in 23 plants, while solar accounts for 31.3% with 3,848 MW spread across 58 installations. Coal contributes 24.9% through just 4 plants totaling 3,058 MW. Battery storage, wind, hydro, and other sources make up the remainder, at 4.2%, 3.1%, 2.1%, and 1.3% respectively.
The largest plant by capacity is Hunter, a coal facility with 1,472 MW. Lake Side Power Plant, a natural gas station with 1,247 MW, ranks second, followed by Intermountain Power Project at 1,093 MW, also natural gas. Huntington, another coal plant, holds 1,016 MW. Green River Energy Center — Hybrid, a solar facility, rounds out the five largest with 800 MW. These plants represent substantial portions of the state's fleet.
Utah's generating fleet spans from Granite, which came online in August 1896, through newly commissioned plants completed in June 2026. This range encompasses more than a century of power infrastructure development and reflects the state's evolving energy portfolio.
