$135 million Houston battery storage facility breaks ground

coming soon

SMT Energy and CenterPoint Energy have partnered with utility infrastructure solutions provider Irby Construction Company to break ground on a 160 megawatt battery energy storage system (BESS) located in the Houston zone of the ERCOT market.

“We are proud to be underway and deliver this grid-strengthening project to Houston,” Kevin Midei, SVP of engineering, procurement and construction, at SMT Energy, said in a news release.

The BESS, SMT Houston IV, is expected to support grid stability, deliver fast-response power during peak demands and provide resiliency and renewable integration. The project is expected to be online by 2026 and store and dispatch enough electricity to power 8,800 homes in Texas annually.

SMT Energy is the project owner and developer, and CenterPoint Energy will serve as the interconnecting utility, integrating the system into Houston’s broader electrical network,” according to the companies. Irby Construction will serve as the engineering, procurement, and construction (EPC) contractor, and construction of the project is expected to be completed by July. On May 14, the companies broke ground with a ribbon-cutting ceremony to symbolize the start of the build.

“Projects like this demonstrate how collaboration and forward-thinking infrastructure come together to power a more resilient energy future,” Tony Gardner, SVP and chief customer officer at CenterPoint, said in a news release. “At CenterPoint, we recently completed nearly 90 percent of our overall grid resiliency improvements. This is one more action we are taking to build a more resilient and reliable grid to better serve our customers.”

In March, Colorado-based SMT Energy secured $135 million in funding for the SMT Houston IV, led by Macquarie and KeyBanc Capital Markets as joint lead arrangers. In 2023, SMT Energy and joint venture partner SUSI Partners announced plans to add 10 battery storage projects to Texas, which would double capacity from 100 megawatts to 200 megawatts in the Houston and Dallas areas.

In 2019, Irby began construction on the Manatee BESS site with Florida Power and Light (FPL), which was the world’s largest BESS project at the time. Irby has built over 30 BESS sites and has more than 20 currently under construction or contract.

Engie signs deal to supply wind power for Texas data center

wind deal

Houston-based Engie North America, which specializes in generating low-carbon power, has sealed a preliminary deal to supply wind power to a Cipher Mining data center in Texas.

Under the tentative agreement, Cipher could buy as much as 300 megawatts of clean energy from one of Engie’s wind projects. The financial terms of the deal weren’t disclosed.

Cipher Mining develops and operates large data centers for cryptocurrency mining and high-performance computing.

In November, New York City-based Cipher said it bought a 250-acre site in West Texas for a data center with up to 100 megawatts of capacity. Cipher paid $4.1 million for the property.

“By pairing the data center with renewable energy, this strategic collaboration supports the use of surplus energy during periods of excess generation, while enhancing grid stability and reliability,” Engie said in a news release about the Cipher agreement.

The Engie-Cipher deal comes amid the need for more power in Texas due to several factors. The U.S. Energy Information Administration reported in October that data centers and cryptocurrency mining are driving up demand for power in the Lone Star State. Population growth is also putting pressure on the state’s energy supply.

Last year, Engie added 4.2 gigawatts of renewable energy capacity worldwide, bringing the total capacity to 46 gigawatts as of December 31. Also last year, Engie signed a new contract with Meta (Facebook's owner) and expanded its partnership with Google in the U.S. and Belgium.

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.

Syzygy unveils plans for groundbreaking sustainable aviation fuel facility

coming soon

Houston-based Syzygy Plasmonics announced plans to develop what it calls the world's first electrified facility to convert biogas into sustainable aviation fuel (SAF).

The facility, known as NovaSAF 1, will be located in Durazno, Uruguay. It is expected to produce over 350,000 gallons of SAF annually, which would be considered “a breakthrough in cost-effective, scalable clean fuel,” according to the company.

"This is more than just a SAF plant; it's a new model for biogas economics," Trevor Best, CEO of Syzygy Plasmonics, said in a news release. "We're unlocking a global asset class of underutilized biogas sites and turning them into high-value clean fuel hubs without pipelines, costly gas separation, or subsidy dependence.”

The project is backed by long-term feedstock and site agreements with one of Uruguay's largest dairy and agri-energy operations, Estancias del Lago, while the permitting and equipment sourcing are ongoing alongside front-end engineering work led by Kent.

Syzygy says the project will result in a 50 percent higher SAF yield than conventional thermal biogas reforming pathways and will utilize both methane and CO2 naturally found in biogas as feedstocks, eliminating the need for expensive CO2 separation technologies and infrastructure. Additionally, the modular facility will be designed for easy replication in biogas-rich regions.

The new facility is expected to begin commercial operations in Q1 2027 and produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel. The company says that once fully commercialized the facility will produce SAF at Jet-A fuel cost parity.

“We believe NovaSAF represents one of the few viable pathways to producing SAF at jet parity and successfully decarbonizing air travel,” Best added in the release.
