Overview
- A new analysis by Utah State physicist Robert Davies estimates the campus would dump a 16-gigawatt thermal load into Hansel Valley, including 7 to 8 gigawatts of waste heat, driving roughly 5°F daytime and 28°F nighttime temperature spikes.
- Box Elder County commissioners advanced the plan after large protests, and residents have filed more than 3,800 formal objections to a related water-rights transfer and sought a countywide referendum.
- Developers say the site could draw up to 9 gigawatts and would run on on-site natural-gas generation rather than the state grid, which they argue will create thousands of jobs and aid U.S. AI efforts.
- Opponents warn cooling water demands could further stress the shrinking Great Salt Lake, and a University of Utah atmospheric scientist cited in an opinion piece estimated a full gas build-out could raise Utah’s annual CO2 emissions by more than 50%.
- The project now faces state reviews of water transfers and air and water permits, while parallel fights over incentives and siting have become common in U.S. data-center booms from Missouri to Michigan.
