J.J. Watt takes a run at energy sector with Base Power investment

Since retiring from the NFL three years ago, Houston Texans legend J.J. Watt has been exploring a new field—investing.

In 2023, the former defensive end and current CBS Sports football analyst bought a stake in English soccer team Burnley FC. A year later, he invested in the PopUp Bagels chain.

This summer, Watt made what may be his highest-profile investment yet. He contributed to a $1 billion Series D round for Austin-based energy startup Base Power, which has an office in Houston. It’s Watts’ first investment in the energy sector.

“I like companies that solve real problems, and Base is lowering power bills, protecting families, and building the whole thing themselves right here in Texas,” Watt said in a company news release.

“What impressed me wasn’t just how fast they’ve grown,” he adds. “It’s that they’ve already saved Texans millions on their power bills and kept thousands of homes running when the lights went out. That’s why I invested.”

Base Power is building a distributed network of residential batteries that’s designed to strengthen the grid and lower electrical bills. The startup now powers more than 30,000 homes in Texas, including the Houston area, and recently expanded to Illinois.

Base Power’s $1 billion round lifted its valuation to $13 billion. Since being founded in 2023, the startup has raised more than $2.5 billion.

“JJ is a legend in this state, and he earned that as much for how he shows up off the field as for what he did on it,” says Zach Dell, co-founder and CEO of Base Power. "He spent a full day with us asking every hard question he could think of, and then he switched to Base himself. We’re glad to have him partnering with us.”

Zach Dell is the only son of Austin billionaire Michael Dell, chairman and CEO of Round Rock-based Dell Technologies. Michael Dell grew up in Bellaire.

Houston-based quantum energy technology startup Casimir Inc. has been awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force.

SpaceWERX is the innovation arm of the U.S. Space Force and a division within AFWERX, the incubator and innovation arm of the United States Department of the Air Force. The Air Force Research Laboratory and SpaceWERX, along with many other government agencies, help support innovation through the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) grants and contracts.

As part of the new contract, Casimir will work to refine a fully independent generator. Casimir’s solid-state power technology could support national security missions by providing reliable power even in difficult-to-service environments.

In May, Casimir emerged from stealth, netting a $12 million seed round to commercialize its quantum energy chip. The semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company aims to include the chips in large-scale energy systems that can power homes, commercial infrastructure and electric vehicles.

“This STTR funds some analysis work to address our proposed scaling approach of making our chips multi-layer to increase aggregate power,” Harold “Sonny” White, founder and CEO of Casimir, tells Energy Capital.

White adds that the company will work with Texas A&M to develop chip planarization techniques to support Casimir’s plans to scale. Additionally, White says the company is working with the U.S. Space Force to explore more applications for its technology.

“Casimir’s technology brings a new capability to the market in the form of our persistent power chips,” White adds. “This approach will be relevant to ultra-low-power electronics, and with the scaling approach we are developing, connected with the STTR work, will eventually be relevant to consumer electronics and beyond.”

Casimir has previously reported that it plans to commercialize its first-generation MicroSparc chip by 2028. The chips are expected to power devices for years without the need for replacements.

The total funding for this project has not yet been disclosed.
