The Bureau of Land Management (BLM) and the U.S. Forest Service Inyo National Forest on August 13 signed the Record of Decision approving a new 40-megawatt geothermal project near Mammoth Lakes, California. The Casa Diablo IV Geothermal Development Project will be built on lands administered by the Inyo National Forest and on private lands within four existing federal geothermal leases. The project will include construction of a new geothermal power plant, up to 16 new production and injection wells, multiple pipelines, and an electric transmission line.

Ormat Nevada Inc. will develop the project on public and private land. When completed, the project would produce enough energy to power 36,000 homes. See the BLM press release.
