BOISE, IDAHO--(Marketwired - April 22, 2014) - U.S. Geothermal Inc. (NYSE MKT:HTM)(TSX:GTH) (the "Company"), a leading renewable energy company focused on the development, production and sale of electricity from geothermal energy, announced today that it has successfully completed the previously announced acquisition of Ram Power, Corp.'s ("Ram") Geysers project for a total of $6.4 million in cash. The Ram subsidiaries included in the acquisition are Western Geopower, Inc., Skyline Geothermal Holdings, Inc., and Etoile Holdings, Inc., which in turn includes all membership interests in Mayacamas Energy LLC and Skyline Geothermal LLC.

"Acquiring this project with 5 completed production/injection wells, having enough total initial steam production for roughly 30 megawatts gross, is a huge head start. We are currently evaluating two development approaches for this project: the first involves obtaining a new PPA to replace the previously expired PPA's and constructing a new power plant; while the second option involves selling steam to one of several companies currently operating power plants in the Geysers," said Dennis Gilles, Chief Executive Officer of U.S. Geothermal Inc. "Having over $90 million previously invested in the project will allow us to finish development at substantially reduced costs, and with drilling risk significantly reduced given that most of the wells needed have already been completed. We are very excited to advance the Geysers project to its completion."

Additional details regarding the acquisition can be found in the initial April 7, 2014 press release:
