THERMO - If everything goes as planned, Utah's Raser Technologies Inc.
within the next four to six weeks will begin generating up to 14 megawatts
of electricity from its new geothermal power plant in Beaver County.
To hear Raser's management and fans such as Sen. Orrin Hatch tell it, the
firm is launching a new era of energy production with its plant capable of
producing electricity from low-temperature geothermal wells that until now
weren't viewed as hot enough to produce power.
"Our low-temperature technology can make geothermal a mainstream source of
energy for the nation," Raser Chief Executive Brent Cook said Thursday,
after a ribbon-cutting ceremony at the plant located about 35 miles west of
Beaver.
Once completed, the plant will have cost about $50 million to build.
It will supply the bulk of its power - 10 megawatts - to Anaheim, Calif.,
which is under contract to purchase the power for $78 per megawatt. The
other four megawatts will be used to run the geothermal plant. A megawatt is
enough to serve about 750 homes.
The plant uses a new and relatively untested technology developed by UTC
Power, which is a division of United Technologies Corp. and a sister company
to Carrier Corp., known for its heating and air conditioning products.

operations, said the Raser plant is the first significant deployment of the
company's "PureCycle" technology.
"To date, we have two units installed in Alaska, two in New Mexico and one
in Guatemala," Fox said.
Each PureCycle generator - there are 50 now installed at Raser's plant -
will generate about 280 kilowatts of electricity. "They basically operate
like an air conditioning unit, only in reverse," Fox said. "Hot water goes
in and is used to heat a fluid that turns a turbine. Kilowatts [and cooled
water] come out."
Cook said Raser is working on eight other geothermal projects, including
seven in the western U.S. and one in Indonesia. But he acknowledged that the
nation's credit crisis could slow their development.
The plant is named in honor of Hatch, who introduced legislation that helped
make the financing of the geothermal plant possible.
Hatch, who attended the ribbon-cutting ceremony, lauded the company for
moving quickly to get the plant up and running, with the drilling of the
geothermal wells starting a year ago and construction taking just six
months. He noted that it typically takes five to seven years to develop a
geothermal plant.
"If Raser can continue to replicate this successful model, it will unlock
this country's most abundant and practical sources of renewable energy," he
said.
