In a new blog post spotlighting Houston-based geothermal power startup Fervo Energy, billionaire Bill Gates — a Fervo investor — predicts geothermal will eventually supply up to 20 percent of the world’s electricity, up from his previous estimate of as much as 5 percent.

Today, geothermal accounts for less than 1 percent of electricity generated around the world, according to the International Energy Agency. The agency forecasts geothermal will represent up to 15 percent of global power by 2050.

“Geothermal power will have a big role to play in our clean energy future, and it’s exciting to see companies like Fervo push the technology to new depths,” Gates wrote.

Gates’ more than $1 billion Breakthrough Energy Ventures fund has contributed to the $982 million pool of money that Fervo has raised since its founding in 2017. Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. Its valuation has been estimated at $1.4 billion.

The Microsoft billionaire published the blog post on his Gates Notes website after touring the site of Fervo’s Cape Station geothermal project, which is under construction in Utah. Fervo says Cape Station will be the world’s largest geothermal plant, capable of someday producing up to 2 gigawatts of power.

Earlier this year, Fervo raised $206 million to put toward the development of Cape Station. Of that amount, $100 million came from Breakthrough Energy Catalyst, a green tech investment program backed by Gates, according to Inc.com.

The first phase of Cape Station is scheduled to be completed in 2026, with first-year power generation pegged at 100 megawatts. An additional 500 megawatts of power-producing capacity is slated to go online in 2028.

“Geothermal is one of the most promising ways to deliver clean energy that’s reliable and affordable,” Gates wrote.

In the blog post, Gates praised the simplicity of geothermal energy.

“The interior of the Earth is incredibly hot, and the deeper you go, the hotter the ground becomes,” he explained. “If you pump fluid deep enough to be warmed by this heat and then pump it back to the surface, you can turn the hot liquid into steam and use it to spin turbines and generate electricity — just like many other types of power plants.”

Gates noted that horizontal drilling is one of Fervo’s biggest innovations. The company extends its wells horizontally by as much as 5,000 feet at the deepest point. It couples horizontal drilling with hydraulic fracturing, or fracking, to extract geothermal energy from rock formations.

Most wells at Cape Station are 8,000 to 9,000 feet deep, and the deepest one is 15,000 feet below the surface, Gates pointed out.

Gates also emphasized the water-conserving, closed-system setup at Cape Station.

“Geothermal energy is one of the more climate-friendly sources of power, but one of its downsides is how much water it uses. … Fervo’s technology captures all the water that would’ve been lost and recirculates it underground to keep the system running,” he wrote.

Fervo Energy lands $200 million in capital for new geothermal project

fresh funding

Houston-based Fervo Energy, a producer of geothermal power, has secured $205.6 million in capital to help finance its geothermal project in southern Utah.

The money will go toward the first and second phases of Cape Station, a geothermal energy plant being developed in Beaver County, Utah. Beaver County is roughly an equal distance between Salt Lake City and Las Vegas.

The $205.6 million in capital came from three sources:

$100 million in equity from Breakthrough Energy Catalyst, a Kirkland, Washington-based platform that invests in emissions-reducing projects.
$60 million addition to Fervo’s existing loan from Mercuria, a Swiss energy and commodities trader. The revolving loan now totals $100 million.
$45.6 million in additional bridge debt financing from XRL-ALC, an affiliate of Irvington, New York-based X-Caliber Rural Capital. X-Caliber is a USDA-approved lender. The initial bridge loan was $100 million.

The first phase of Cape Station will supply 100 megawatts of carbon-free electricity to the power grid starting next year. Another 400 megawatts of capacity is supposed to go online by 2028. Fervo has permission to expand Cape Station’s capacity to as much as 2 gigawatts. On an annual basis, 2 gigawatts can supply enough electricity to power about 1.4 million homes.

“These investments demonstrate what we’ve known all along: Fervo’s combination of technical excellence, commercial readiness, and market opportunity makes us a natural partner for serious energy capital. The confidence our investors have in Fervo and in the Cape asset affirms that next-generation geothermal is ready to play a defining role in America’s energy future,” David Ulrey, Fervo’s CFO, said in a news release.

CenterPoint and partners launch AI initiative to stabilize the power grid

AI infastructure

Houston-based utility company CenterPoint Energy is one of the founding partners of a new AI infrastructure initiative called Chain Reaction.

Software companies NVIDIA and Palantir have joined CenterPoint in forming Chain Reaction, which is aimed at speeding up AI buildouts for energy producers and distributors, data centers and infrastructure builders. Among the initiative’s goals are to stabilize and expand the power grid to meet growing demand from data centers, and to design and develop large data centers that can support AI activity.

“The energy infrastructure buildout is the industrial challenge of our generation,” Tristan Gruska, Palantir’s head of energy and infrastructure, says in a news release. “But the software that the sector relies on was not built for this moment. We have spent years quietly deploying systems that keep power plants running and grids reliable. Chain Reaction is the result of building from the ground up for the demands of AI.”

CenterPoint serves about 7 million customers in Texas, Indiana, Minnesota and Ohio. After Hurricane Beryl struck Houston in July 2024, CenterPoint committed to building a resilient power grid for the region and chose Palantir as its “software backbone.”

“Never before have technology and energy been so intertwined in determining the future course of American innovation, commercial growth, and economic security,” Jason Wells, chairman, president, and CEO of CenterPoint added in the release.

In November, the utility company got the go-ahead from the Public Utility Commission of Texas for a $2.9 billion upgrade of its Houston-area power grid. CenterPoint serves 2.9 million customers in a 12-county territory anchored by Houston.

A month earlier, CenterPoint launched a $65 billion, 10-year capital improvement plan to support rising demand for power across all of its service territories.

ERCOT approves $9.4B project to improve grid, meet data center demand

power project

The Electric Reliability Council of Texas, which manages the electric grid for 90 percent of Texans, is undertaking a $9.4 billion project to improve the reliability and efficiency of statewide power distribution. The initiative comes as ERCOT copes with escalating demand for electricity from data centers and cryptocurrency-mining facilities.

The project, approved Dec. 9 by ERCOT’s board, will involve building a 1,109-mile “super highway” of new 765-kilovolt transmission lines. One kilovolt equals 1,000 volts of electricity.

According to the Hoodline Dallas news site, the $9.4 billion project represents the five- to six-year first phase of ERCOT’s Strategic Transmission Expansion Plan (STEP). Hoodline says the plan, whose price tag is nearly $33 billion, calls for 2,468 miles of new 765-kilovolt power lines.

STEP will enable ERCOT to “move power longer distances with fewer losses,” Hoodline reports.

Upgrading the ERCOT grid is a key priority amid continued population growth in Texas, along with the state’s explosion of new data centers and cryptocurrency-mining facilities.

ERCOT says about 11,000 megawatts of new power generation capacity have been added to the ERCOT grid since last winter.

But in a report released ahead of the December board meeting, ERCOT says it received 225 requests this year from large power users to connect to its grid — a 270 percent uptick in the number of megawatts being sought by mega-users since last December. Nearly three-fourths (73 percent) of the requests came from data centers.

Allan Schurr, chief commercial officer of Houston-based Enchanted Rock, a provider of products and services for microgrids and onsite power generation, tells Energy Capital that the quickly expanding data center industry is putting “unprecedented pressure” on ERCOT’s grid.

“While the state has added new generation and transmission capacity, lengthy interconnection timelines and grid-planning limitations mean that supply and transmission are not keeping pace with this rapid expansion,” Schurr says. “This impacts both reliability and affordability.”

For families in Texas, this could result in higher energy bills, he says. Meanwhile, critical facilities like hospitals and grocery stores face a heightened challenge of preventing power outages during extreme weather or at other times when the ERCOT grid is taxed.

“I expect this trend to continue as AI and high-density computing grow, driving higher peak demand and greater grid variability — made even more complex by more renewables, extreme weather and other large energy users, like manufacturers,” Schurr says.

According to the Pew Research Center, data centers accounted for 4 percent of U.S. electricity use in 2024, and power demand from data centers is expected to more than double by 2030. Data centers that support the AI boom make up much of the rising demand.

In September, RBN Energy reported more than 10 massive data-center campuses had been announced in Texas, with dozens more planned. The Lone Star State is already home to roughly 400 data centers.

“Texas easily ranks among the nation’s top states for existing data centers, with only Virginia edging it out in both data-center count and associated power demand,” says RBN Energy.

Federal judge strikes Trump order blocking wind energy development

wind win

In a win for clean energy and wind projects in Texas and throughout the U.S., a federal judge struck down President Donald Trump’s “Day One” executive order that blocked wind energy development on federal lands and waters, the Associated Press reports.

Judge Patti Saris of the U.S. District Court for the District of Massachusetts vacated Trump’s executive order from Jan. 20, declaring it unlawful and calling it “arbitrary and capricious.”

The challenge was led by a group of state attorneys general from 17 states and Washington, D.C., which was led by New York Attorney General Letitia James. The coalition pushed back against Trump's order , arguing that the administration didn’t have the authority to halt project permitting, and that efforts would critically impact state economies, the energy industry, public health and climate relief efforts.

White House spokesperson Taylor Rogers told the Associated Press that wind projects were given unfair treatment during the Biden Administration and cited that the rest of the energy industry suffered from regulations.

According to the American Clean Power Association, wind is the largest source of renewable energy in the U.S. It provides 10 percent of the electricity generated—and growing. Texas leads the nation in wind electricity generation, accounting for 28 percent of the U.S. total in 2024, according to the U.S. Energy Information Administration.

Several clean-energy initiatives have been disrupted by recent policy changes, impacting Houston projects.

The Biden era Inflation Reduction Act’s 10-year hydrogen incentive was shortened under Trump’s One Big Beautiful Bill Act, prompting ExxonMobil to pause its Baytown low-carbon hydrogen project. That project — and two others in the Houston region — also lost federal support as part of a broader $700 million cancellation tied to DOE cuts.

Meanwhile, Texas House Democrats have urged the administration to restore a $250 million Solar for All grant that would have helped low-income households install solar panels.
