Geothermal Study Amendments
HB 401 directs Utah's Office of Energy Development to study whether geothermal energy facilities can be developed at or near existing or retired coal power plants. The study must assess underground heat levels, infrastructure suitability, potential electricity output, costs, and economic impacts for each site, with results published online by December 31, 2027. The office must report annually to the Public Utilities, Energy, and Technology Committee before November meetings. This procedural bill affects the Office of Energy Development and coal plant sites, but does not fund construction or alter energy regulations.
