Houston geothermal company picks up power purchase agreement in California

Houston-based Fervo Energy, a provider of geothermal power, has signed up one of the country’s largest utilities as a new customer.

Under two 15-year deals, Southern California Edison has agreed to buy a total of 320 megawatts of geothermal power from Fervo. Financial terms weren’t disclosed. The power will be enough to deliver electricity to the equivalent of 350,000 homes.

Southern California Edison, based in Rosemead, California, serves about 15 million people throughout a 50,000-square-mile area in California.

The utility will purchase the power from Fervo’s 400-megawatt Cape Station plant, which is under construction in southwest Utah. The plant’s first phase, providing 70 megawatts of power, is expected to be online by 2026.

“This announcement is another milestone in California’s commitment to clean zero-carbon electricity,” David Hochschild, chair of the California Energy Commission, says in a news release.

“Enhanced geothermal systems complement our abundant wind and solar resources by providing critical base load when those sources are limited,” he adds. “This is key to ensuring reliability as we continue to transition away from fossil fuels.”

In June, Fervo announced it would supply 115 megawatts of geothermal power for Google’s two data centers in Nevada. Two years ago, Fervo signed a deal with energy aggregators in California to supply 53 megawatts of geothermal power from Cape Station.

“As electrification increases and climate change burdens already fragile infrastructure, geothermal will only play a bigger role in U.S. power markets,” says Dawn Owens, Fervo's head of development and commercial markets.

Houston-based quantum energy technology startup Casimir Inc. has been awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force.

SpaceWERX is the innovation arm of the U.S. Space Force and a division within AFWERX, the incubator and innovation arm of the United States Department of the Air Force. The Air Force Research Laboratory and SpaceWERX, along with many other government agencies, help support innovation through the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) grants and contracts.

As part of the new contract, Casimir will work to refine a fully independent generator. Casimir’s solid-state power technology could support national security missions by providing reliable power even in difficult-to-service environments.

In May, Casimir emerged from stealth, netting a $12 million seed round to commercialize its quantum energy chip. The semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company aims to include the chips in large-scale energy systems that can power homes, commercial infrastructure and electric vehicles.

“This STTR funds some analysis work to address our proposed scaling approach of making our chips multi-layer to increase aggregate power,” Harold “Sonny” White, founder and CEO of Casimir, tells Energy Capital.

White adds that the company will work with Texas A&M to develop chip planarization techniques to support Casimir’s plans to scale. Additionally, White says the company is working with the U.S. Space Force to explore more applications for its technology.

“Casimir’s technology brings a new capability to the market in the form of our persistent power chips,” White adds. “This approach will be relevant to ultra-low-power electronics, and with the scaling approach we are developing, connected with the STTR work, will eventually be relevant to consumer electronics and beyond.”

Casimir has previously reported that it plans to commercialize its first-generation MicroSparc chip by 2028. The chips are expected to power devices for years without the need for replacements.

The total funding for this project has not yet been disclosed.
