Low temp geothermal: "PureCycle® geothermal power plant at Chena Hot Springs Resort in Alaska was selected as Project of the Year in the renewable/sustainable energy category by Power Engineering magazine.  .. The Chena Hot Springs Resort in Alaska has the first geothermal power plant in the state. It also is the site of the lowest temperature geothermal resource (165°F) ever used for commercial power generation in the world. The resort’s UTC Power PureCycle® geothermal system was commissioned in August and provides power for the resort’s on-site electrical needs. All 44 buildings at the resort – including a greenhouse, hotel, cabins and ice museum – are linked by a geothermal district heating system."  More info:  "Although output from the installation is considered small for a base load power plant, the Chena plant represents a huge leap forward for moderate geothermal development and greatly expands the number of geothermal resources that can be economically developed. Prior to the operation of the power plant at Chena, the lowest temperature geothermal resource ever developed for commercial power generation was 208 F."  9:29:11 AM
