XGS Energy and California Community Power (CC Power) have announced the execution of a Geothermal Exploration, Offtake, and Development Engagement (GEODE) to support the development of a 115-MW next-generation geothermal project in California. The agreement highlights XGS’s readiness to execute at scale to support CC Power’s member agencies, collectively representing more than 2.7 million customers across nine California Community Choice Aggregators (CCAs).

“Geothermal energy offers a renewable resource that can provide valuable round-the-clock reliability that cannot be provided by California’s existing portfolio,” said Alexander Morris, General Manager of CC Power.

“This GEODE Agreement with XGS allows CC Power to thoughtfully build relationships with geothermal developers like XGS Energy who are unlocking incremental geothermal capacity within California that supports local reliability, jobs, and investment.”

XGS’s water-independent system aims to harness the further geothermal potential of California by enabling the development of dry, hot rock resources. XGS’s recent commercial-scale demonstration in Inyo County, California showcased its ability to efficiently develop and operate projects within the state.

The announcement further expands XGS’s multi-gigawatt U.S. West development pipeline, which includes a 150 MW grid-connected project in New Mexico for which the company recently announced partnerships with Vallourec and Baker Hughes. XGS anticipates advancing a similar industrial execution ecosystem of trusted, scale-ready partners in California to accelerate deployment. XGS is actively developing multiple California project sites.

“California has been clear about what it needs: clean, firm power that can be delivered at scale and on a near-term timeline,” said Dr. Lucy Darago, Chief Commercial Officer of XGS Energy.

“Our partnership with CC Power sends a strong demand signal for next-generation geothermal, and XGS is ready to deliver – using a water-independent system designed to unlock California’s vast hot rock resources and provide reliable power for communities across the state.”
