Elko, a small town (population 15,000) located in the desert country of Northeast Nevada has for the last several years quietly been going about the development of not one, but two geothermal district heating systems. The Elko Heat Company (EHC) system, operated by a private entity and serving the downtown area, has been in operation since 1982. The Elko County School District (ECSD) system, in operation since 1986, serves a large group of municipal customers on the east side of town
