A report on Arizona's renewable energy resources commissioned by Arizona's three largest utilities, Arizona Public Service (APS), Salt River Project and Tucson Electric Power (TEP), identified more than 5,000 megawatts (MW) of untapped renewable energy resources in Arizona.Two geothermal sites in eastern Arizona, Clifton and Gillard hot springs, were estimated to be able to produce 20 and 15 MW of electricity, respectively, for a total of 215 GWh/year. Because the production tax credit will expire before they can be brought online, there costs will be high, but comparable to solar power currently.
AZGS received well cores from the Clifton prospect, which are available for research.
