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.

Houston-based climatech startup Aquanta Vision achieved key milestones in 2025 for its enhanced methane-detection app and has its focus set on future funding.

Among the achievements was the completion of the National Science Foundation’s Advanced Sensing and Computation for Environmental Decision-making (ASCEND) Engine. The program, based in Colorado and Wyoming, awarded a total of $3 million in grants to support the commercialization of projects that tackle critical resilience challenges, such as water security, wildfire prediction and response, and methane emissions.

Aquanta Vision’s funding went toward commercializing its NETxTEN app, which automates leak detection to improve accuracy, speed and safety. The company estimates that methane leaks cost the U.S. energy industry billions of dollars each year, with 60 percent of leaks going undetected. Additionally, methane leaks account for around 10 percent of natural gas's contribution to climate change, according to MIT’s climate portal.

Throughout the months-long ASCEND program, Aquanta Vision moved from the final stages of testing into full commercial deployment of NETxTEN. The app can instantly identify leaks via its physics-based algorithms and raw video output of optical gas imaging cameras. It does not require companies to purchase new hardware, requires no human intervention and is universally compatible with all optical gas imaging (OGI) cameras. During over 12,000 test runs, 100 percent of leaks were detected by NETxTEN’s system, according to the company.

The app is geared toward end-users in the oil and gas industry who use OGI cameras to perform regular leak detection inspections and emissions monitoring. Aquanta Vision is in the process of acquiring new clients for the app and plans to scale commercialization between now and 2028, Babur Ozden, the company’s founder and CEO, tells Energy Capital.

“In the next 16 months, (our goal is to) gain a number of key customers as major accounts and OEM partners as distribution channels, establish benefits and stickiness of our product and generate growing, recurring revenues for ourselves and our partners,” he says.

The company also received an investment for an undisclosed amount from Marathon Petroleum Corp. late last year. The funding complemented follow-on investments from Ecosphere Ventures and Odyssey Energy Advisors.

Ozden says the funds will go toward the extension of its runway through the end of 2026. It will also help Aquanta Vision grow its team.

Ozden and Marcus Martinez, a product systems engineer, founded Aquanta Vision in 2023 and have been running it as a two-person operation. The company brought on four interns last year, but is looking to add more staff.

Ozden says the company also plans to raise a seed round in 2027 “to catapult us to a rapid growth phase in 2028-29.”
