Ultra-fast EV charging bays coming to Waffle House locations in Texas and beyond

power breakfast

Scattered, smothered and ... charged?

Starting next year, EV drivers can connect to ultra-fast charging stations at select Waffle House locations throughout Texas, courtesy of bp pulse.

The EV arm of British energy giant bp announced a strategic partnership with the all-day breakfast chain this week. The company aims to deploy a network of 400kW DC fast chargers and a mix of CCS and NACS connectors at Waffle House locations in Texas, Georgia, Florida, and other restaurants in the South.

Each Waffle House site will feature six ultra-fast EV charging bays, allowing drivers to "(enjoy) Waffle House’s 24/7 amenities," the announcement reads.

“Adding an iconic landmark like Waffle House to our growing portfolio of EV charging sites is such an exciting opportunity. As an integrated energy company, bp is committed to providing efficient solutions like ultra-fast charging to support our customers’ mobility needs," Sujay Sharma, CEO of bp pulse U.S., said in a news release. "We’re building a robust network of ultra-fast chargers across the country, and this is another example of third-party collaborations enabling access to charging co-located with convenient amenities for EV drivers.”

The news comes as bp pulse continues to grow its charging network in Texas.

The company debuted its new high-speed electric vehicle charging site, known as the Gigahub, at the bp America headquarters in Houston last year. In partnership with Hertz Electrifies Houston, it also previously announced plans to install a new EV fast-charging hub at Hobby Airport. In a recent partnership with Simon Malls, bp also shared plans to install EV charging Gigahubs at The Galleria and Katy Mills Mall.

bp has previously reported that it plans to invest $1 billion in EV charging infrastructure by 2030, with $500 million invested in by the end of 2025.

Houston hypersonic engine co. completes first successful test flight

Taking Off

Houston-based Venus Aerospace successfully completed the first U.S. flight test of its proprietary engine at a demonstration at Spaceport America in New Mexico.

Venus’ next-generation rotating detonation rocket engine (RDRE) is supported by a $155,908 federal Small Business Innovation Research (SBIR) grant from NASA and aims to enable vehicles to travel four to six times the speed of sound from a conventional runway. The recent flight test was the first of an American-developed engine of its kind.

"With this flight test, Venus Aerospace is transforming a decades-old engineering challenge into an operational reality,” Thomas d'Halluin, managing partner at Airbus Ventures, an investor in Venus, said in a news release. “Getting a rotating detonation engine integrated, launch-ready, and validated under real conditions is no small feat. Venus has shown an extraordinary ability to translate deep technical insight into hardware progress, and we're proud to support their bold approach in their attempt to unlock the hypersonic economy and forge the future of propulsion."

Venus’ RDRE operates through supersonic shockwaves, called detonations, that generate more power with less fuel. It is designed to be affordable and scalable for defense and commercial systems.

The RDRE is also engineered to work with the company's air-breathing detonation ramjet, the VDR2, which helps enable aircraft to take off from a runway and transition to speeds exceeding Mach 6. Venus plans for full-scale propulsion testing and vehicle integration of this system. Venus’ ultimate goal is to develop a Mach 4 reusable passenger aircraft, known as the Stargazer M4.

"This milestone proves our engine works outside the lab, under real flight conditions," Andrew Duggleby, Venus co-founder and chief technology officer, said in the release. "Rotating detonation has been a long-sought gain in performance. Venus' RDRE solved the last but critical steps to harness the theoretical benefits of pressure gain combustion. We've built an engine that not only runs, but runs reliably and efficiently—and that's what makes it scalable. This is the foundation we need that, combined with a ramjet, completes the system from take-off to sustained hypersonic flight."

The hypersonic market is projected to surpass $12 billion by 2030, according to Venus.

"This is the moment we've been working toward for five years," Sassie Duggleby, CEO and co-founder of Venus Aerospace, added. "We've proven that this technology works—not just in simulations or the lab, but in the air. With this milestone, we're one step closer to making high-speed flight accessible, affordable, and sustainable."

Investment giant to acquire TXNM Energy for $11.5 billion

m&a moves

Blackstone Infrastructure, an investment giant with $600 million in assets under management, has agreed to buy publicly traded TXNM Energy in a debt-and-stock deal valued at $11.5 billion.

TXNM Energy is the parent company of Lewisville-based Texas New Mexico Power (TNMP), which supplies electricity to more than 270,000 homes and businesses throughout Texas. Its Houston-area service territory includes Alvin, Angleton, Brazoria, Dickinson, Friendswood, La Marque, League City, Sweeny, Texas City and West Columbia.

Once Blackstone Infrastructure wraps up the deal in the second half of 2026, Albuquerque, New Mexico-based TXNM will no longer be a public company. But TNMP’s headquarters will remain in Texas and its rates will continue to be set by the Public Utility Commission of Texas. TNMP was founded in 1934.

Blackstone Infrastructure is affiliated with investment powerhouse Blackstone Inc., which has $1.2 trillion in assets under management and is the world’s largest investment manager.

“TNMP has done an excellent job of meeting its customers’ growing demand for electricity and supporting the communities it serves,” Sean Klimczak, Blackstone’s global head of infrastructure, said in a news release. “We look forward to utilizing our long-term investment commitments to support TNMP as they continue on this path of high-demand growth across Texas.”

During TXNM’s fourth-quarter earnings call in February, Chairwoman and CEO Patricia Vincent-Collawn said the company’s five-year Texas capital investment plan had grown by more than $1 billion.

“Our future is so bright with these increased investment levels that we are now targeting earnings growth of 7 percent to 9 percent through 2029,” Vincent-Collawn said.

“Our financial expectations are driven by the continued expansion of grid infrastructure supporting growth and reliability in our Texas service territory,” she added.

In 2024, TXNM reported revenue of $1.96 billion, up 1.7 percent from the previous year.
