USGS issues new Geothermal Assessment - Washington State has 30,000 MW potential of EGS
Posted on October 5th, 2008 by Lawrence Molloy
In the first comprehensive assessment since 1978, the US Geologic Survey has issued a new survey of the hydrothermal and EGS potential of the Western United States. Building from recent assessments by the Western Governors Association, State Geologic Surveys, private data and federal assessment they issue conservative, mean and low probability estimates. The study included resources greater than 90 degrees C and up to a depth of 6km. Pristine lands and lands proximal to National Parks were excluded. A total of 241 geothermal sites were identified.
Washington State’s identified resources are 0.25% of the national assessment and expand to 1.25% of the potential when EGS is included.
