Utah's generating fleet in context
Utah holds 11.5 gigawatts of generating capacity as of May 2026, ranking 38th among the 51 largest power plant fleets in the nation. Natural gas supplies 35.2% of the state's nameplate capacity across 23 plants, making it the dominant fuel type. Coal provides 26.7% through just 4 plants, while solar has grown to 26.5% of capacity spread across 55 installations. Battery storage accounts for 4.5%, wind for 3.4%, and hydroelectric for 2.3%, with other sources making up the remaining 1.4%.
The five largest plants shape the fleet's profile. Hunter, a coal plant in Emery County, leads at 1,472 megawatts. Lake Side Power Plant, a natural gas facility in Utah County, reaches 1,247 megawatts, while the Intermountain Power Project in Millard County, also natural gas, comes in at 1,093 megawatts with its first units online in 2025. Huntington, another coal plant in Emery County, provides 1,016 megawatts, and Currant Creek, a natural gas installation in Juab County, adds 567 megawatts.
The state's generating fleet spans nearly a century of equipment. Cutler Hydro, first online in July 1927, ranks as the oldest plant still listed. The newest is Enterprise Storage, which came online in April 2026. This reflects both the durability of older assets and the rapid recent addition of battery storage capacity to the grid.
