Open Mountain Energy and Power Planet have officially entered a cooperation agreement to develop enhanced geothermal at the Star Peak site in Nevada.
Open Mountain Energy LLC (OME), and Power Planet Inc (PP) have signed a cooperation agreement to develop enhanced geothermal systems (EGS), specifically at the Star Peak geothermal power project within OME’s Humboldt House geothermal resource area in Nevada. The partners aim to conduct technology verification and commercial development of EGS, eyeing an initial 19.8 MW development, with possibility of large-scale projects ranging from 100 MW to 200 MW.
OME is a wholly owned subsidiary of the Kaishan Group. The cooperation agreement follows up on the signing of the term sheet between the two parties earlier this year. According to the previous announcement, the goal is to start drilling operations within twelve months of the contract signing.
The Star Peak project was chosen as the site of the technology verification as it already has a proven resource base, existing power generation infrastructure, and grid connection. This would allow for better resource characterization and a pathway for revenue generation should the EGS pilot prove successful. According to a 2011 study, the Humboldt House block possess 200 to 500 MW of EGS resource potential.
OME currently has two operational geothermal power projects in the United States – the aforementioned Star Peak project, and the 4-MW Whitegrass No.1 binary geothermal power plant in Yerington, Nevada. It holds the licenses for several other geothermal areas, including the non-operational Bottle Rock geothermal power plant, which the company acquired in 2022.
The Kaishan Group has global presence in the geothermal sector, with wholly or partially controlled projects in Indonesia, Kenya, the United States, Türkiye, and Hungary.
