Utah's largest solar and battery storage project is officially online
Utah's largest solar and battery storage project has officially come online. The facility combines solar power generation with large-scale battery storage, marking a significant step in the state's renewable energy capacity.
Background
- Utah's largest combined solar-plus-battery facility, covering 4,500 acres in Iron County, is now operational. It's a 600 MW solar farm paired with 2,400 MWh of battery storage — enough to power roughly 180,000 homes for a few hours after sunset.
- The project was developed by Enyo Renewable Energy (owned by South Korea's SK Group) and is operated by Utah Municipal Power Agency (UMPA), a utility serving 11 member cities across the state.
- This is part of a broader U.S. trend: as solar and wind generation grow, battery storage is rapidly being added to shift renewable power into evening hours when demand peaks.
- The project's size is notable — at 600 MW solar / 2,400 MWh storage, it rivals or exceeds other large hybrid plants in the Intermountain West, a region previously dominated by coal-fired power.
