Summary
HB 401 would direct the Office of Energy Development and the Utah Geological Survey to study whether operating or decommissioned coal-fired power plant sites have geothermal potential (feasibility assessment of subsurface temperatures, steam quality, production potential and infrastructure suitability); the committee passed the bill unanimously with a favorable recommendation.
Representative Watkins presented HB 401 as a limited, exploratory measure to assess geothermal potential at current or former coal-fired power plant locations. The sponsor said the bill is intended as a low-cost, information-gathering study and is not intended to replace operating coal plants.
"We're just trying it's kind of a very low level, but kinda smart way to look at to see if there's anything there," Representative Watkins said, describing planned study elements, which include assessing subsurface temperature, steam quality, potential electricity production, infrastructure suitability and estimated capital and economic impacts.
Representative Peck asked whether producing such a study could later be used to argue for taking coal plants offline. The sponsor replied the study is exploratory and not aimed at replacing existing coal facilities. Jake Garfield, deputy director of the Utah Office of Energy Development, told the committee his office is "excited about the potential for geothermal development in the state" and said, "we do not... think there's certainly room for both geothermal power and coal power in Utah," indicating the office expects both resource types to have roles in meeting demand.
Representative Dominguez said the bill provides an opportunity for districts with legacy power or mining sites to explore additional resource uses. Public commenters who joined online expressed support for the study's potential to identify clean-energy options.
Representative Peck moved that HB 401 be favorably passed as introduced; the committee voted in favor and the motion passed unanimously. The bill will advance from committee with a favorable recommendation.
