Welcome to the Montana Geothermal Website

Publication: Consumer's Guide to Geothermal Energy in Montana


The Montana Geothermal Program was established by Sage Resources of Missoula, the U.S. Department of Energy (DOE), and the State of Montana in May, 2005. The goal of this program is to identify and update geothermal information for Montana. This website provides the access to regional, site-specific and general geothermal energy information applicable to site development in Montana.

The potential for geothermal development in Montana, and all Western states, continues to be assessed. The Department of Energy's GDOET program has compiled information from such analyses, which indicates that Montana has more than 25,000 square miles of high-potential sites and areas.

Specific information for 50 geothermal sites is now available on this site. The site-specific information includes location, physical surface conditions (temperature, flow, etc.), reservoir characteristics, geology and existing uses. The site profiles include site maps and a direct link to digital maps. The maps can be expanded for a broader view, combined with photographic views of detailed areas or used as general area locations. In addition, the website contains a database of physical and chemical data for more than 300 geothermal springs or wells throughout the state. There are also links to additional site information from geothermal evaluations by the Geo-Heat Center, the Geothermal Resources Council, the U.S. Geological Survey (USGS) and the Montana Bureau of Mines. Future educational activities will be also be posted on this site. General geothermal information is also available for geothermal uses applicable for Montana sites or uses.

Montana has the potential to develop significant new sources of geothermal energy. Increasing the domestic sources of clean energy is one of the most critical problems facing our nation, according to policymakers. The National Energy Policy encourages development of clean and diverse sources of energy. Geothermal energy can help supply clean, naturally occurring sources of both electrical energy and direct-heat substitutes. This website and the geothermal database are first steps toward developing these resources.
