Geothermal Heating in Boise

Administered by the Boise Public Works Department, the largest direct use system in the United States supplies energy-efficient heat to over 55 businesses in the downtown core area. Direct use systems not only provide heat to buildings, but also provide hot water for recreation (developed hot springs resorts), greenhouses (heating), and aquaculture (raising warm-water fish and aquatic plants).

After a recent upgrade to the City's geothermal system, the city of Boise now injects 100% of the water back into the aquifer. 100-percent injection was made possible by constructing a supply pipeline behind several businesses on River Street. Completion of the supply line provides an estimated additional 20-million gallons of water for proposed future projects, such as possible expansion onto the Boise State University campus. The water savings is enough to heat 500,000 square feet of buildings per year.

Currently, four independent heating districts operate geothermal systems within Boise. The Boise Public Works Department operates and collects fees for the system that serves the downtown core area. The State of Idaho operates the system that heats the Idaho State Capitol and several other buildings with in the Capitol Mall area. The Veterans Administration (VA) provides service to the VA campus, and the Boise Warm Springs Water District provides service to the residential properties in the vicinity of Warm Springs Avenue.
