Fervo Energy has announced the execution of two power purchase agreements (PPAs) with one of the US’ largest utility companies, Southern California Edison (SCE), for the provision of 320MW worth of geothermal energy to 350,000 homes across the state’s southern region.

SCE will purchase the power from Fervo Energy’s 400MW Cape Station project currently under construction in Utah, with the first 70MW phase of the project scheduled to be operational by 2026.

California Energy Commission Chair, David Hochschild, commented how the 15-year agreement marks “another milestone in California’s commitment to clean, zero-carbon electricity” and the enhanced geothermal systems will “complement our abundant wind and solar resources by providing critical baseload when those sources are limited.”

Californian promise

In 2021, the California Public Utilities Commission issued a mid-term reliability (MTR) mandate which requires utilities to produce 1,000MW of non-weather-dependent, non-battery, zero0emission energy to increase the reliability of the state’s electric grid. This movement catalysed demand for geothermal energy within California.

Dawn Owens, VP and Head of Development & Commercial Markets for Fervo Energy, said, “Geothermal stands as the dependable and adaptable solution for California’s journey towards a fully decarbonised grid. As electrification increases and climate change burdens already fragile infrastructure, geothermal will only play a bigger role in the US power markets.

“Fervo looks forward to continuing to meet these needs, providing firm, clean power to help balance California’s energy portfolio.”
