The Milford, Utah FORGE team's proposed candidate site proceeded to Phase 2. To learn more about their findings you can review the Milford, Utah FORGE team's Phase 1 Report and data submissions on the Geothermal Data Repository.
The proposed Milford, Utah FORGE site is located in the Milford Energy Corridor in eastern Beaver County, Utah. The propose site will be built on private land and EGI has land access agreements with the three main land owners/administrators: Murphy-Brown LLC., Utah School Trust Lands, and the Bureau of Land Management. The proposed site is 10 mi (16 km) north of Milford, the closest town, and 217 mi (350 km) south of Salt Lake City. The project area is rural and covers approximately 15.5 mi2 (25 km2), and includes a deep hydrothermal exploration well.
Data obtained during the area’s long history of geothermal exploration and development has allowed the team to characterize the subsurface temperatures, rock types, seismicity, and groundwater systems. Geothermal development in the area began in the 1970’s east of the Forge site. Fifteen deep exploration and development wells and over 80 gradient wells were drilled, extensively logged and sampled in support of the exploration activities. These studies found temperatures as high as 446°F (230°C) at depth, but were unable to produce fluids. Temperature gradients and surrounding wells indicate the targeted zone is outside the boundaries of the Roosevelt Hot Springs hydrothermal system and that the site meets the requirements for temperature, depth, and rock.
- The University of Utah Seismic Stations has been recording seismic activity in the area since 1981.
- Beaver County has a rich history of renewable energy power, where the first liquid-dominated geothermal plant in the U.S. was commissioned at Roosevelt Hot Springs in 1984.
- The proposed Milford site is adjacent to a wind farm and solar PV plant.
