Solar energy company to open new tech center in Houston

A Houston energy services company has announced the upcoming opening of a state-of-the-art energy testing and integration technologies hub.

Sunnova Energy International Inc. will open the Sunnova Adaptive Technology Center in 2024. The center, which will come sometime in the first quarter of the year, is part of Sunnova Adaptive Home, Sunnova Adaptive Business, and Sunnova Adaptive Community service offerings. Founded in Houston in 2012, Sunnova aims to “create a better energy service at a better price.”

The ATC will house Sunnova technologies, including a microgrid system powered by a grid simulator and a solar array simulator with the ability to replicate various grid and solar array conditions. An interchangeable inverter and battery test beds, and a fully-functioning model home equipped with full-sized appliances, including a range, oven, refrigerator and HVAC system, will also be part of the new ATC.

This will assist Sunnova engineering teams to perform system level validation to integrate disparate technologies for reliable operation during various grid, solar and home conditions. The ATC will also be the home for service technicians that help with customer issues.

"We've always been committed to ensuring high standards of quality and service excellence for our customers," William J. (John) Berger, CEO at Sunnova, says in a news release. "With the ATC, both our customers and dealers can trust that they are partnering with a company that has an unwavering focus on innovative technologies, integrated energy solutions, quality control, and service excellence."

This announcement comes just two months after the completed expansion of Sunnova’s Global Command Center, which is a similar facility that works with cutting-edge technologies, and customer service. The ATC will also continue to develop its customer-facing experiences like the Sunnova App, and its Sunnova Sentient technology platform, which works with energy management.

“The ATC won’t be a static configuration, but a responsive, flexible arrangement that will effectively pull together top, industry-leading technologies to deliver customized energy solutions to our customers,” Michael Grasso, executive vice president and chief revenue officer at Sunnova, says in the release. “It’s a tremendous effort to qualify hardware and integrate all the technologies we work with – but doing all of this ensures the services reaching our customers are top of the line.”

Houston-based Quaise Energy is looking to raise $200 million to support the development of a 50-megawatt superhot geothermal plant in Oregon.

The company is seeking $100 million in Series B funding, plus an additional $100 million from grants, debt and project-level finance, a representative from the company tells Energy Capital. Axios first reported the news late last month.

Quaise specializes in terawatt-scale geothermal power. It is known for its millimeter-wave drilling technology, which was developed at MIT.

The company's Project Obsidian development in central Oregon will combine conventional drilling with its millimeter-wave technology. Quaise says the project, targeted to come online in 2030, could be the first commercial plant to operate in superhot rock, a more efficient and abundant resource, but one that requires more advanced and durable drilling technology.

Quaise says Obsidian would initially generate 50 megawatts of "always-on" power and would be designed to add 200 megawatts as additional wells are developed. A power-purchase deal has already been signed for the initial 50 megawatts with an undisclosed customer.

A representative from the company says Quaise would also use the funding to continue advancing its millimeter-wave technology and prepare it for commercialization.

Last year, the company drilled to a depth of about 330 feet using its millimeter-wave technology at its field site in Central Texas.

“Our progress this year has exceeded all expectations,” Carlos Araque, CEO and president of Quaise Energy, said at the time. “We’re drilling faster and deeper at this point than anyone believed possible, proving that millimeter-wave technology is the only tool capable of reaching the superhot rock needed for next-generation geothermal power. We are opening up a path to a new energy frontier.”

Canary Media reports that Quaise plans to drill to nearly 3,300 feet later this year and to deploy its millimeter-wave technology at its power plant in 2027.

Quaise raised $21 million in a Series A1 financing round in 2024 and a $52 million Series A in 2022. Major investors include Prelude Ventures, Safar Partners, Mitsubishi Corporation, Nabors Industries, TechEnergy and others.

Quaise was one of eight Houston-area companies to appear on Time magazine and Statista’s list of America’s Top GreenTech Companies of 2025.
