AltaRock Energy

AltaRock Energy Inc., headquartered in Seattle, Washington and having a technology development office in Sausalito, California, is a privately held corporation that focuses on the development of geothermal energy resources and Enhanced Geothermal Systems (EGS). AltaRock has filed patent applications and holds exclusive licenses for related intellectual property related to EGS. In 2008, it started its first project near The Geysers to demonstrate the ability of EGS to be a reliable, renewable and clean source for the production of electric power.

AltRock’s efforts to expand EGS technologies are supported by a 2006 Massachusetts Institute of Technology (MIT) report that concluded EGS has the potential to provide 100 GWe (gigawatts of electricity) or more for the U.S. by 2050.

Founded in 2007 by serial entrepreneur Andrew Perlman and his business partners, AltaRock has received backing from investors such as Google.org, Advanced Technology Ventures, and Vulcan Capital, as well as demonstration grant funding from the United States Department of Energy (DOE).
