As Texas places a $350 million bet on nuclear energy, a budget and policy adviser for Gov. Greg Abbott has been tapped to head the newly created Texas Advanced Nuclear Energy Office.

Jarred Shaffer is now director of the nuclear energy office, which administers the $350 million Texas Advanced Nuclear Development Fund. The fund will distribute grants earmarked for the development of more nuclear reactors in Texas.

Abbott said Shaffer’s expertise in energy will help Texas streamline nuclear regulations and guide “direct investments to spur a flourishing and competitive nuclear power industry in the Lone Star State. Texas will lead the nuclear renaissance.”

The Texas Nuclear Alliance says growth of nuclear power in the U.S. has stalled while China and Russia have made significant gains in the nuclear sector.

“As Texas considers its energy future, the time has come to invest in nuclear power — an energy source capable of ensuring grid reliability, economic opportunity, and energy and national security,” Reed Clay, president of the alliance, said.

“Texas is entering a pivotal moment and has a unique opportunity to lead. The rise of artificial intelligence and a rebounding manufacturing base will place unprecedented demands on our electricity infrastructure,” Clay added. “Meeting this moment will require consistent, dependable power, and with our business-friendly climate, streamlined regulatory processes, and energy-savvy workforce, we are well-positioned to become the hub for next-generation nuclear development.”

Abbott’s push for increased reliance on nuclear power in Texas comes as public support for the energy source grows. A 2024 survey commissioned by the Texas Public Policy Institute found 55 percent of Texans support nuclear energy. Nationwide support for nuclear power is even higher. A 2024 survey conducted by Bisconti Research showed a record-high 77 percent of Americans support nuclear energy.

Nuclear power accounted for 7.5 percent of Texas’ electricity as of 2024, according to the Nuclear Energy Institute, but made up a little over 20 percent of the state’s clean energy. Currently, four traditional reactors produce nuclear power at two plants in Texas. The total capacity of the four nuclear reactors is nearly 5,000 megawatts.

Because large nuclear plants take years to license and build, small factory-made modular reactors will meet much of the shorter-term demand for nuclear energy. A small modular reactor has a power capacity of up to 300 megawatts. That’s about one-third of the generating power of a traditional nuclear reactor, according to the International Atomic Energy Agency.

A report from BofA Global Research predicts the global market for small nuclear reactors could reach $1 trillion by 2050. These reactors are cheaper and safer than their larger counterparts, and take less time to build and produce fewer CO2 emissions, according to the report. Another report, this one from research company Bloomberg Intelligence, says soaring demand for electricity — driven mostly by AI data centers — will fuel a $350 billion boom in nuclear spending in the U.S., boosting output from reactors by 63 percent by 2050.

Global nuclear capacity must triple in size by 2050 to keep up with energy demand tied to the rise of power-gobbling AI data centers, and to accomplish decarbonization and energy security goals, the BofA report says. Data centers could account for nine percent of U.S. electricity demand by 2035, up from about four percent today, according to BloombergNEF.

As the Energy Capital of the World, Houston stands to play a pivotal role in the evolution of small and large nuclear reactors in Texas and around the world. Here are just three of the nuclear power advancements that are happening in and around Houston:

Houston is poised to grab a big chunk of the more than 100,000 jobs and more than $50 billion in economic benefits that Jimmy Glotfelty, a former member of the Texas Public Utility Commission, predicts Texas will gain from the state’s nuclear boom. He said nuclear energy legislation signed into law this year by Abbott will provide “a leg up on every other state” in the race to capitalize on the burgeoning nuclear economy.

“Everybody in the nuclear space would like to build plants here in Texas,” Inside Climate News quoted Glotfelty as saying. “We are the low-regulatory, low-cost state. We have the supply chain. We have the labor.”

Rice University team finds economical way to recycle data center heat into power

waste not

As data centers expand, their energy demands rise as well. Researchers at Rice University have discovered a way to capture low-temperature waste heat from data centers and convert it back into usable power.

The team has introduced a novel solar thermal-boosted organic Rankine cycle (ORC)—a power system that uses a safe working fluid to make electricity from heat. The design incorporates low-cost rooftop flat-plate solar collectors, which warm the data center’s coolant stream before it enters the ORC. The findings, published in Solar Energy, show that the additional “solar bump” helps surpass the technical roadblocks with data center waste, which has typically been too cool to generate power on its own.

The research was supported by the Alliance for Sustainable Energy LLC, the National Renewable Energy Laboratory and the U.S. Department of Energy.

“There’s an invisible river of warm air flowing out of data centers,” Laura Schaefer, the Burton J. and Ann M. McMurtry Chair of Mechanical Engineering at Rice and co-author of the paper, said in a news release. “Our question was: Can we nudge that heat to a slightly higher temperature with sunlight and convert a lot more of it into electricity? The answer is yes, and it’s economically compelling.”

Traditionally, electric heat pumps have been used to raise temperatures before recovery, but the benefits were limited because the pumps consumed significant extra power.

Kashif Liaqat, a graduate student in mechanical engineering at Rice, and Schaefer achieved a "temperature lift” by using solar energy to create thermoeconomic models. They modeled affordable, low-profile rooftop solar collectors that fed into an ORC and tied into a liquid-cooling loop. The collectors were validated against industry tools and tested at some of America’s largest data center hubs in Ashburn, Virginia, and Los Angeles, which provided varying climate challenges.

The system recovered 60 percent to 80 percent more electricity annually from the same waste heat, with a 60 percent boost in Ashburn and an 80 percent boost in Los Angeles, according to Rice. It also achieved over 8 percent higher ORC efficiency during peak hours, and an increase in annual average efficiency. The approach also lowered the cost of electricity from the recovered power by 5.5 percent in Ashburn and by 16.5 percent in Los Angeles.

“What the industry considers a weakness becomes a strength once you add solar,” Liaqat said in a news release. “That’s great news for modern data centers.”

Next up, the team will look to pilot its hybrid system in operational sites and explore thermal storage, which the researchers hope could bank solar heat during the day to assist with energy recovery efforts at night.

grid boost

Hitachi Energy, whose U.S. headquarters is in Houston, has earmarked more than $1 billion to manufacture infrastructure for the U.S. electric grid, which is coping with greater power demand from data centers and AI platforms.

Of that sum, $457 million is dedicated to building a power transformer factory in Virginia. Hitachi Energy said it’ll be the largest facility of its kind in the U.S.

“Power transformers are a linchpin technology for a robust and reliable electric grid and winning the AI race. Bringing production of large power transformers to the U.S. is critical to building a strong domestic supply chain for the U.S. economy and reducing production bottlenecks, which is essential as demand for these transformers across the economy is surging,” said Andreas Schierenbeck, CEO of Switzerland-based Hitachi Energy, which generates revenue of about $16 billion.

The Hitachi announcement aligns with various priorities of the Trump administration. The White House is promoting more U.S.-based manufacturing, more power to accommodate data centers and AI, and greater use of U.S. energy resources.

“If we are going to win the AI race, reindustrialize, and keep the lights on, America is going to need a lot more reliable energy,” U.S. Energy Secretary Chris Wright said.

Engie launches next-generation data center development in Texas

coming soon

Houston-based Engie North America has entered into an agreement with Wyoming-based Prometheus Hyperscale to develop liquid-cooled data centers at select renewable and battery storage energy facilities along Texas’ I-35 corridor. Its first AI-ready data center compute capacity sites are expected to go live in 2026.

“By leveraging our robust portfolio of wind, solar, and battery storage assets — combined with our commercial and industrial supply capabilities and deep trading expertise — we're providing integrated energy solutions that support scalable, resilient, and sustainable infrastructure," David Carroll, chief renewables officer and SVP of ENGIE North America, said in a news release.

Prometheus plans to use its high-efficiency, liquid-cooled data center infrastructure in conjunction with ENGIE's renewable and battery storage assets. Both companies believe they can meet the growing demand for reliable, sustainable compute capacity, which would support AI and other more demanding workloads.

"Prometheus is committed to developing sustainable, next-generation digital infrastructure for AI," Bernard Looney, chairman of Prometheus Hyperscale, said in the release. "We cannot do this alone—ENGIE's existing assets and expertise as a major player in the global energy transition make them a perfect partner as we work to build data centers that meet market needs today and tomorrow."

On-site power generation provider Conduit Power will assist Prometheus for near-term bridging and back-up solutions, and help tenants to offset project-related carbon emissions through established market-based mechanisms.

More locations are being planned for 2027 and beyond.

"Our collaboration with Prometheus demonstrates our shared approach to finding innovative approaches to developing, building and operating projects that solve real-world challenges,” Carroll added in the release.

As electric bills rise, evidence mounts that data centers share blame

Data Talk

Amid rising electric bills, states are under pressure to insulate regular household and business ratepayers from the costs of feeding Big Tech's energy-hungry data centers.

It's not clear that any state has a solution and the actual effect of data centers on electricity bills is difficult to pin down. Some critics question whether states have the spine to take a hard line against tech behemoths like Microsoft, Google, Amazon and Meta.

But more than a dozen states have begun taking steps as data centers drive a rapid build-out of power plants and transmission lines.

That has meant pressuring the nation's biggest power grid operator to clamp down on price increases, studying the effect of data centers on electricity bills or pushing data center owners to pay a larger share of local transmission costs.

Rising power bills are “something legislators have been hearing a lot about. It’s something we’ve been hearing a lot about. More people are speaking out at the public utility commission in the past year than I’ve ever seen before,” said Charlotte Shuff of the Oregon Citizens’ Utility Board, a consumer advocacy group. “There’s a massive outcry.”

Not the typical electric customer

Some data centers could require more electricity than cities the size of Pittsburgh, Cleveland or New Orleans, and make huge factories look tiny by comparison. That's pushing policymakers to rethink a system that, historically, has spread transmission costs among classes of consumers that are proportional to electricity use.

“A lot of this infrastructure, billions of dollars of it, is being built just for a few customers and a few facilities and these happen to be the wealthiest companies in the world,” said Ari Peskoe, who directs the Electricity Law Initiative at Harvard University. “I think some of the fundamental assumptions behind all this just kind of breaks down.”

A fix, Peskoe said, is a “can of worms" that pits ratepayer classes against one another.

Some officials downplay the role of data centers in pushing up electric bills.

Tricia Pridemore, who sits on Georgia’s Public Service Commission and is president of the National Association of Regulatory Utility Commissioners, pointed to an already tightened electricity supply and increasing costs for power lines, utility poles, transformers and generators as utilities replace aging equipment or harden it against extreme weather.

The data centers needed to accommodate the artificial intelligence boom are still in the regulatory planning stages, Pridemore said, and the Data Center Coalition, which represents Big Tech firms and data center developers, has said its members are committed to paying their fair share.

But growing evidence suggests that the electricity bills of some Americans are rising to subsidize the massive energy needs of Big Tech as the U.S. competes in a race against China for artificial intelligence superiority.

Data and analytics firm Wood Mackenzie published a report in recent weeks that suggested 20 proposed or effective specialized rates for data centers in 16 states it studied aren’t nearly enough to cover the cost of a new natural gas power plant.

In other words, unless utilities negotiate higher specialized rates, other ratepayer classes — residential, commercial and industrial — are likely paying for data center power needs.

Meanwhile, Monitoring Analytics, the independent market watchdog for the mid-Atlantic grid, produced research in June showing that 70% — or $9.3 billion — of last year's increased electricity cost was the result of data center demand.

States are responding

Last year, five governors led by Pennsylvania's Josh Shapiro began pushing back against power prices set by the mid-Atlantic grid operator, PJM Interconnection, after that amount spiked nearly sevenfold. They warned of customers “paying billions more than is necessary.”

PJM has yet to propose ways to guarantee that data centers pay their freight, but Monitoring Analytics is floating the idea that data centers should be required to procure their own power.

In a filing last month, it said that would avoid a "massive wealth transfer” from average people to tech companies.

At least a dozen states are eyeing ways to make data centers pay higher local transmission costs.

In Oregon, a data center hot spot, lawmakers passed legislation in June ordering state utility regulators to develop new — presumably higher — power rates for data centers.

The Oregon Citizens’ Utility Board says there is clear evidence that costs to serve data centers are being spread across all customers — at a time when some electric bills there are up 50% over the past four years and utilities are disconnecting more people than ever.

New Jersey’s governor signed legislation last month commissioning state utility regulators to study whether ratepayers are being hit with “unreasonable rate increases” to connect data centers and to develop a specialized rate to charge data centers.

In some other states, like Texas and Utah, governors and lawmakers are trying to avoid a supply-and-demand crisis that leaves ratepayers on the hook — or in the dark.

Doubts about states protecting ratepayers

In Indiana, state utility regulators approved a settlement between Indiana Michigan Power Co., Amazon, Google, Microsoft and consumer advocates that set parameters for data center payments for service.

Kerwin Olsen, of the Citizens Action Council of Indiana, a consumer advocacy group, signed the settlement and called it a “pretty good deal” that contained more consumer protections than what state lawmakers passed.

But, he said, state law doesn't force large power users like data centers to publicly reveal their electric usage, so pinning down whether they're paying their fair share of transmission costs "will be a challenge.”

In a March report, the Environmental and Energy Law Program at Harvard University questioned the motivation of utilities and regulators to shield ratepayers from footing the cost of electricity for data centers.

Both utilities and states have incentives to attract big customers like data centers, it said.

To do it, utilities — which must get their rates approved by regulators — can offer “special deals to favored customers” like a data center and effectively shift the costs of those discounts to regular ratepayers, the authors wrote. Many state laws can shield disclosure of those rates, they said.

In Pennsylvania, an emerging data center hot spot, the state utility commission is drafting a model rate structure for utilities to consider adopting. An overarching goal is to get data center developers to put their money where their mouth is.

“We’re talking about real transmission upgrades, potentially hundreds of millions of dollars,” commission chairman Stephen DeFrank said. “And that’s what you don’t want the ratepayer to get stuck paying for."

ERCOT steps up grid innovation efforts to support growing power demand

grid boost

As AI data centers gobble up more electricity, the Electric Reliability Council of Texas (ERCOT) — whose grid supplies power to 90 percent of Texas — has launched an initiative to help meet challenges presented by an increasingly strained power grid.

ERCOT, based in the Austin suburb of Taylor, said its new Grid Research, Innovation, and Transformation (GRIT) initiative will tackle research and prototyping of emerging technology and concepts to “deeply understand the implications of rapid grid and technology evolution, positioning ERCOT to lead in the future energy landscape.”

“As the ERCOT grid continues to rapidly evolve, we are seeing greater interest from industry and academia to collaborate on new tools and innovative technologies to advance the reliability needs of tomorrow’s energy systems,” ERCOT President and CEO Pablo Vegas said in a news release. “These efforts will provide an opportunity to share ideas and bring new innovations forward, as we work together to lead the evolution and expansion of the electric power grid.”

In conjunction with the GRIT initiative, ERCOT launched the Research and Innovation Partnership Engagement (RIPE) program. The program enables partners to work with ERCOT on developing technology aimed at resolving grid challenges.

To capitalize on ideas for grid improvements, the organization will host its third annual ERCOT Innovation Summit on March 31 in Round Rock. The summit “brings together thought leaders across the energy research and innovation ecosystem to explore solutions that use innovation to impact grid transformation,” ERCOT said.

“As the depth of information and industry collaboration evolves, we will continue to enhance the GRIT webpages to create a dynamic and valuable resource for the broader industry to continue fostering strong collaboration and innovation with our stakeholders,” said Venkat Tirupati, ERCOT’s vice president of DevOps and grid transformation.

ERCOT’s GRIT initiative comes at a time when the U.S. is girding for heightened demand for power, due in large part to the rise of data centers catering to the AI boom.

A study released in 2024 by the Electric Power Research Institute (EPRI) predicted electricity for data centers could represent as much as 9.1 percent of total power usage in the U.S. by 2030. According to EPRI, the share of Texas electricity consumed by data centers could climb from 4.6 percent in 2023 to almost 11 percent by 2030.

A report issued in 2024 by the federal government’s Lawrence Berkeley National Laboratory envisions an even faster increase in data-center power usage. The report projected data centers will consume as much as 12 percent of U.S. electricity by 2028, up from 4.4 percent in 2023.

In 2023, the EPRI study estimated, 80 percent of the U.S. electrical load for data centers was concentrated in two states, led by Virginia and Texas. The University of Texas at Austin’s Center for Media Engagement reported in July that Texas is home to 350 data centers, second only to Virginia.

“The U.S. electricity sector is working hard to meet the growing demands of data centers, transportation electrification, crypto-mining, and industrial onshoring, while balancing decarbonization efforts,” David Porter, EPRI’s vice president of electrification and sustainable energy strategy, said. “The data center boom requires closer collaboration between large data center owners and developers, utilities, government, and other stakeholders to ensure that we can power the needs of AI while maintaining reliable, affordable power to all customers.”

Fervo Energy spotlighted by Bill Gates as geothermal’s global growth driver

geothermal predictions

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.
