About This Project

Cobb, California
Expected December 31, 2025

OME acquired the Bottle Rock Project wellfield from Alta Rock Energy in September 2022. The Bottle Rock Power Project was originally a 55MW facility in the Geysers Known Geothermal Resource Area near Cobb, CA. The project was originally owned by California Department of Water Resources and has changed ownership several times since its original operation in 1980. The project has been in a non-operational state since 2015 due to lack of steam to operate at the expected levels. OME intends to install a new 8.0 MW facility at the existing plant site and is currently working through the permitting process to begin construction. OME anticipates the project will come online in 2025.
