California: Next-Generation Geothermal Demonstration Launched
|Positive Impact:||Proving the technology for advanced EGS applications, this first-of-its-kind achievement successfully demonstrated that EGS technologies are commercially viable.|
|EERE Investment:||$7 million|
|Clean Energy Sector:||Renewable electricity generation|
At the outer edges of the largest operating geothermal field in the world, the Energy Department and project partner Calpine Corporation achieved the nation’s first sustained enhanced geothermal system (EGS) demonstration success in 2012. The Geysers EGS Demonstration project successfully created a new and distinct reservoir, yielding enough steam to produce 5 MW of electricity, a program milestone. Because of existing infrastructure, this EGS reservoir demonstrates that stimulating hot rock on the margins of existing hydrothermal fields can secure higher field productivity at low cost.
The Geothermal Technologies Office researches, develops, and validates innovative and cost-competitive technologies and tools to locate, access, and develop geothermal resources in the United States.
