PROJECT SUMMARY

In February 2011, the Department of Energy issued a $97 million loan guarantee to finance USG Oregon, a 22-MW geothermal power plant, located at the Neal Hot Springs in eastern Oregon. USG Oregon started commercial operations in November 2012.

TECHNOLOGY INNOVATION

USG Oregon uses a more efficient method of extracting thermal energy from subterranean hot water, potentially allowing development of geothermal power from lower temperature wells that were previously considered uneconomical. Its “supercritical binary geothermal cycle” technology was developed and manufactured in the U.S.  As opposed to older geothermal power generators, USG Oregon utilizes geothermal generators supplied by Turbine Air Systems (TAS) that feature a more environmentally friendly R-134a refrigerant as the working fluid. In geothermal power plants using older technology, the geothermal well has to provide higher-temperature heat to generate the steam that turns turbines and generates electricity.

ECONOMIC IMPACT

USG Oregon created 150 construction jobs and is expected to support 10 permanent jobs.

CLIMATE BENEFIT

USG Oregon is expected to generate 149,000 megawatt-hours of clean energy per year. It is expected to prevent 86,000 metric tons of carbon dioxide emissions annually.
