Geothermal Energy in Alaska

In one line

Alaska geothermal regions and projects.

Geothermal energy in Alaska comes from three geothermally active regions: the Interior hot springs, the Southeast hot springs and the Ring of Fire volcanoes. The state’s operating geothermal power plant is at Chena Hot Springs Resort.[1]

Chena Hot Springs

Chena Hot Springs Resort has 680 kilowatts of generating capacity from organic Rankine cycle generators. Its 165°F water is described as the lowest temperature for an operating geothermal power plant in the world. The source dates a 16-ton absorption chiller at the resort to 2005 but gives no start year for the power plant.[1]

Akutan

The City of Akutan drilled exploratory wells in Hot Springs Bay Valley in 2010 and 2017. They found shallow water over 350°F, but flow rates were too low to produce electricity.[1]

Mount Spurr

The state awarded geothermal leases to Ormat Technologies in 2008 for tracts about 80 miles west of Anchorage, and drilling in 2011 did not reach temperatures able to support a power plant.[1]

Makushin

Exploration in the 1980s near Mount Makushin, outside Dutch Harbor, indicated that tens of megawatts could be generated, and newer plans for the resource are described as evolving.[1]
