PROVO — Raser Technologies Inc. said Wednesday it has begun drilling on a geothermal production well in the Escalante Desert in central Utah for use in another geothermal power plant.

Raser said it is negotiating with a California utility to buy the power that would be generated at the site, which it said would represent the first geothermal power facility built in Utah in 17 years.

Brent Cook, Raser's chief executive officer, said the site could generate up to 10 megawatts of electricity, which would be enough to power about 7,000 typical homes.
