Construction is underway on the Casa Diablo-IV (CD4) binary geothermal project in Mammoth Lakes, California. The project will be the first new geothermal power plant built within the California Independent System Operator balancing authority in the last 30 years.

Incorporating an innovative closed-loop binary process to eliminate the natural carbon emissions associated Source: Silicon Valley Clean Energywith flash steam geothermal energy production, the facility will deliver 14 MW of power to Central Coast Community Energy and Silicon Valley Clean Energy through a contract signed with Ormat Technologies. In total, the project will provide 30 MW of electricity, enough to power 22,000 homes and offset 160,000 tons of carbon dioxide annually. The remaining 16 MW of power will be allocated to the city of Colton in Southern California.

CD4 is estimated to bring over $13 million in economic benefits to the Mammoth Lakes region and will create more than 180 construction jobs.
