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.

Energy transition opportunities are heading to Texas and beyond, according to these experts

incoming

The energy industry in Houston, Texas, and beyond is gearing up for new opportunities within the energy transition, as a recent Houston event and its lineup of experts shared.

At the inaugural ENERGYEAR USA 2023, panelists outlined how their companies are opting into a more personable approach to building sustainable energy solutions – and sustainable communities.

“Most of our renewable projects are in very rural areas. We come to communities that don’t have enough money to invest in their schools, their kids. There’s not a lot of opportunity,” explains David Carroll, chief renewables officer and senior vice president of the North America region for Engie.

“We come in and invest a lot in the construction phase, but after that, we have workers that live there. We are often one of the largest taxpayers in that area,” Carroll continues. “We can provide them cash profit, provide them the tax base, so that we can help provide a future in many of these rural communities that were struggling before we got there.”

Engie, which has closed several coal plants globally ahead of schedule to work toward meeting their commitment to Net Zero by 2045, isn’t the only organization that emphasizes purpose in its pursuit of energy equity.

Power Electronics, the global leader in renewable energy storage, finds purpose through re-purposing field technicians. For the past five years, the organization has transformed talent with electrical equipment experience from the oil and gas industry into renewables. The company doesn’t plan on slowing down, either.

“We are proud to announce here today [that over] the next two years, we will create more than 500 jobs as the largest ever manufacturer of solar inverter and intermediate scale battery inverters in the U.S.,” shares David Salvo, CEO of Power Electronics. “We start manufacturing EV chargers in Houston later this year and are committed to U.S. manufacturing job creation.”

The company saw a need for setting up a Texas manufacturing facility to support growth and was impressed by the volume of Houston talent possessing a deep understanding of both mechanical and electrical equipment from their tenure in upstream oil and gas.

“It is easier to find people here [like that] than anywhere else,” Salvo tells EnergyCapitalHTX. “That is a fact.”

Explosive growth for the region has barely even begun, with expected investments in Texas alone exceeding $60 billion dollars in large scale renewables.

“Because of these investments that we are making, we are able to create good paying jobs… and meet climate goals of getting to a Net Zero economy by 2050,” Jeff Marootian, U.S Department of Energy senior advisor, tells Katie Mehnert, CEO of Ally Energy and DOE Ambassador, during their fireside chat.

“Partnership between government and private sector, ultimately, is creating these opportunities,” Marootian says. “Our challenge is to help identify, help train, help build up that generation of workforce.”

As a final note on the trifecta of purpose, partnering, and governance, Erika Bierschbach, vice president of energy market operations and resource planning for Austin Energy, challenges the power and utilities industry to embrace statistical models over deterministic ones when forecasting energy supply and demand. The upstream oil and gas sector embraced this practice years ago to improve production optimization processes.

On the subject of green energy employment, a recent report found that Houston is a successful hub when it comes to clean energy jobs. SmartAsset, a personal finance website, recently ranked the Houston metro area as the fifth best place in the U.S. for green jobs, which pay an average of 21 percent more than other jobs. And actually, the study found that 2.23 percent of workers in the Houston area hold down jobs classified as “green.”

Houston-based ‘grid in a box’ provider Branch Energy raises $33M

fresh funding

Houston-based startup Branch Energy, which offers a self-contained “grid in a box,” has collected $33 million in a Series B round.

Piva Capital and Clean Energy Ventures led the round, according to a news release. Active Impact Investments, Whitecap Venture Partners, Prelude Ventures, Zero Infinity Partners and Inovia Capital also contributed to the round.

In 2024, Branch raised $10.8 million in an oversubscribed Series A round.

Branch’s business model

Branch, which launched in 2021, says its proprietary Arc “grid in a box” contains everything needed to store and supply electricity. A container about the size of a parking space holds an industrial-grade battery, grid connection equipment, cooling capabilities, autonomous controls and cloud-based management software.

The startup installs Arc systems at warehouses, hotels, factories, stores and other commercial properties. Each system arrives on a flatbed truck and can be online within two days, Branch says.

Under Branch’s business model, a property owner avoids upfront payment for an Arc system.

Aside from equipping a host business with an Arc system, Branch serves as the business’ power provider. The startup says it guarantees savings on the host’s energy bills and delivers backup power during outages.

Branch generates revenue by sending the battery’s stored power to the grid or to customers like hyperscale data centers. It also benefits by shifting energy from low-cost periods at night to high-cost periods during daily power peaks.

The startup handles permitting, installation, insurance and operations for each Arc system. The host provides a parking-lot-sized plot of land for the system.

Alex Ince-Cushman, co-founder and CEO of Branch, says the startup’s “grid in a box” can quickly meet the substantial power requirements of hyperscale data centers.

“We can do it on the timeline of a delivery, not a construction project. Our customers don’t lift a finger, don’t pay a dime and get guaranteed savings,” Ince-Cushman said in the release.

Entering the Illinois market

Branch already operates in Texas and is entering the Illinois market.

PJM, which operates Illinois’ power grid, recently paved the way for major energy users like data centers to connect to the grid sooner when they rely on their own electricity generation. PJM’s territory covers roughly 1.2 million commercial buildings and represents 20 percent of U.S. power demand, according to Branch.

“Grids around the country need the distributed capacity that [the Arc] system can supply, especially in states with fast-growing power demand like Texas and Illinois,” Lee Larson, principal at Piva Capital added in the release.

To keep up with that demand, Branch plans to build tens of thousands of Arc systems in the U.S.

A multibillion-dollar company in the making?

Daniel Goldman, co-founder and managing partner of Clean Energy Ventures, said Branch holds the potential to become a multibillion-dollar competitor in the emerging market for distributed power.

“With utility-scale generation and storage challenged by interconnect and siting constraints, behind-the-meter commercial, and industrial storage sites have become the ultimate market opportunity with ease of interconnect, ability to combine distributed AI data centers, and identifiable savings in rapidly growing markets,” Goldman said.

Kanin Energy raises up to $100M for waste-heat-to-power projects

fresh funding

Kanin Energy, a member of the Greentown Labs climatech and energy incubator in Houston, recently raised as much as $100 million in capital to grow its energy-as-a-service platform.

S2G Investments led a round of up to $50 million, and the Canada Growth Fund chipped in an additional $50 million. The money will primarily support Kanin’s development and operation of waste-heat-to-power projects.

Kanin—founded in 2020 in Calgary, Alberta, Canada—builds and runs onsite power assets for large-scale energy users. The startup says its energy-as-a-service offering lowers power costs, boosts power reliability and decreases emissions.

The company operates a waste-heat-to-power project at Ohio’s University of Dayton. The project supplies zero-emission electricity.

Kanin has a pipeline of projects totaling about 50 megawatts of capacity. This includes a waste-heat-to-power plant at the Phillips 66 Mewbourn gas-processing plant near Greeley, Colorado.

“Kanin was built on the belief that industrial facilities already hold the solution to their own energy challenges, they just need the right partner to execute,” Janice Tran, CEO of Kanin, who is based in Houston, said in a release. “At a time when power costs continue to rise, [our] solutions are an important tool for our industrial customers to manage their costs, operations, and emissions.”

Marisa Sweeney, principal at S2G, says waste heat is a largely underused resource for lowering power costs, alleviating grid congestion and improving power reliability.

The waste-heat-to-power process captures thermal energy from industrial activities and converts it to electricity. This happens without using extra fuel or generating more emissions.

Kanin says up to 58 percent of energy consumed by industrial processes is lost as waste heat. This heat winds up in the atmosphere at thousands of facilities in North America, including oil-and-gas operations, cement plants, and steel mills, the startup says.

Kanin was founded in 2020 in Calgary, Alberta, Canada. It opened offices at Greentown Labs Houston in July 2022.
