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 geothermal company grows relationship with Google to provide power to Nevada

powering up

Houston-based Fervo Energy’s geothermal energy soon will help power the world’s most popular website.

Through a first-of-its-kind proposal, Las Vegas-based public utility NV Energy would supply 115 megawatts of geothermal power generated by Fervo for Google’s two data centers in Nevada. Financial terms weren’t disclosed.

In 2021, Google teamed up with Fervo to develop a pilot project for geothermal power in Nevada. Two years later, electricity from this project started flowing into the Nevada grid serving the two Google data centers. Google spent $600 million to build each of the centers, which are in Henderson, a Las Vegas suburb, and Storey County, which is east of Reno.

The proposed agreement with NV Energy would bring about 25 times more geothermal power capacity to the Nevada grid, Google says, and enable more around-the-clock clean power for the search engine company’s Nevada data centers.

A data center gobbles up 10 to 50 times the energy per square foot of floor space that a typical office building does, according to the U.S. Department of Energy.

“NV Energy and Google’s partnership to develop new solutions to bring clean … energy technology — like enhanced geothermal — onto Nevada’s grid at this scale is remarkable. This innovative proposal will not be paid for by NV Energy’s other customers but will help ensure all our customers benefit from cleaner, greener energy resources,” Doug Cannon, president and CEO of NV Energy, says in a Google blog post.

Utility regulators still must sign off on the proposal.

“If approved, it provides a blueprint for other utilities and large customers in Nevada to accelerate clean energy goals,” Cannon says.

Japanese company launches solar module manufacturing at Houston-area plant

solar plant

A local subsidiary of a Japanese solar equipment manufacturer recently began producing solar modules at a new plant in Humble.

TOYO Co. Ltd.’s TOYO Solar LLC subsidiary can produce 1 gigawatt worth of solar modules per year at a 567,140-square-foot plant it leases in Lovett Industrial’s Nexus North Logistics Park on Greens Road. TOYO Solar’s next phase will accommodate 2.5 gigawatts’ worth of solar module manufacturing. The subsidiary eventually plans to expand manufacturing capacity to 6.5 gigawatts.

For now, TOYO Solar operates only one assembly line at the Humble plant. Once TOYO Solar has five assembly lines up and running, it could employ as many as 750 manufacturing workers there, according to Connect CRE.

TOYO says the plant enlarges its U.S. footprint “to be closer to the majority of its clients, meet the demand for American-made solar panels, and contribute to the growing demand for secure, sustainable energy solutions as demands on the grid continue to rise.”

Last month, TOYO purchased the remaining 24.99 percent stake in TOYO Solar to make it a wholly owned subsidiary. TOYO entered the Houston-area market through its 2024 acquisition of a majority stake in Solar Plus Technology Texas LLC.

NRG makes latest partnership to grow virtual power plant

VPP partners

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
