Is the Production of Geothermal Energy in The Geysers a “Public Nuisance”?

On September 15, less than a fortnight after AltaRock Energy halted its geothermal drilling in The Geysers, the Anderson Springs Community Alliance (ASCA), a small but formidable opponent of the AltaRock project, fired another salvo: this time charging the area’s main producer of geothermal energy with a public nuisance.

In a formal complaint and petition addressed to the Board of Supervisors of Lake and Sonoma Counties for “Remedy of Ongoing Public Nuisance from Geothermal Earthquakes Caused by Operations of Calpine Corp./Geysers Power Company, LLC at The Geysers,” ASCA specifically cited a September 5 magnitude 2.8 earthquake as the latest of more than a thousand magnitude 2.0 or higher temblors epicentered within five miles of Anderson Springs since 2000. These, ASCA contends, constitute an ongoing public nuisance. [A link to the complaint will be posted here when it goes online.]

According to the complaint, “Most residents of Anderson Springs were awakened by the jolt and noise of this earthquake; many were Continue reading “Is the Production of Geothermal Energy in The Geysers a “Public Nuisance”?”

Enhanced Geothermal Energy Project Halted in The Geysers

Steam-powered electricity generation in The GeysersLate in 2008, George Bush’s Department of Energy committed $6 million to Sausalito-based AltaRock Energy (as part of a consortium…see addendum below) for energy production using Enhanced Geothermal Systems (EGS). EGS technology works by by injecting water down a deep well into hot rock, fracturing the rock and creating steam which is piped to the surface where it turns turbines and generates electricity. Yesterday, the project was halted due to drilling problems.
