A French utility company is buying the bulk of Houston-based Broad Reach Power’s battery energy storage business in a deal carrying an equity value of more than $1 billion.

Engie, has agreed to purchase the majority of the startup’s battery storage business from EnCap Energy Transition Fund I and three investment partners — New York City-based Yorktown Partners, Switzerland-based Mercuria Energy, and New York City-based Apollo Infrastructure Funds.

“This acquisition is fully in line with Engie’s strategy: It will contribute to the development of a low-carbon, affordable, and resilient energy system where flexible assets will play a critical role alongside renewables,” says Catherine MacGregor, the utility’s CEO.

Broad Reach launched in 2019 with backing from EnCap Energy Transition, an arm of Houston-based private equity firm EnCap Investments. Apollo Global Management, an asset manager that controls Apollo Infrastructure Funds, bought a 50 percent stake in Broad Reach in 2021.

The deal includes 350 megawatts of grid-scale battery assets that already are operating and 880 megawatts of assets under construction, primarily in the territory served by the Electric Reliability Council of Texas (ERCOT). It also includes a 1.7-gigawatt pipeline of battery storage projects that are in the advanced stage of development and a significant pipeline of early-stage projects.

In July, Broad Reach said it had lined up $435 million in credit facilities to support the 880 megawatts’ worth of systems under construction in Texas and California.

The Broad Reach acquisition does not include the company’s 1.8-gigawatt portfolio of solar and wind power projects, or its four gigawatt-hours’ worth of battery storage in the Mountain West.

The deal is expected to close in the fourth quarter of this year. The purchase price wasn’t disclosed, but the Bloomberg news service reports the deal will cause Engie to “take a $1.6 billion hit” to it net debt.

Shawn Cumberland, managing partner of EnCap and chairman of Broad Reach, calls Broad Reach “the top battery storage player in the U.S. market.” And Corinne Still, an infrastructure partner at Apollo, refers to Broad Reach as “the leading and most innovative” battery energy storage operator in North America.

“It has been a terrific honor and pleasure to be part of the rapid growth of the U.S. energy storage sector from the very beginning and see our company grow into one of the top developers,” says Doug Moorehead, founder and COO of Broad Reach.

Houston startup raises $12M to commercialize quantum energy chip technology

seed funding

Houston-based Casimir has emerged from stealth with a $12 million seed round to commercialize its quantum energy chip.

The round was led by Austin-based Scout Ventures. Lavrock Ventures, Cottonwood Technology, Capital Factory, American Deep Tech, and Tim Draper of Draper Associates also participated in the round. The oversubscribed round exceeded the company’s original $8 million target, according to a news release.

Casimir’s semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company plans to commercialize its first-generation MicroSparc chip by 2028.

The MicroSparc chip measures 5 millimeters by 5 millimeters and is designed to produce 1.5 volts at 25 microamps, comparable to a small rechargeable battery, without degradation and no replacement cycle.

“Casimir represents exactly the kind of breakthrough dual-use technology Scout Ventures was built to back,” Brad Harrison, founder and managing partner at Scout Ventures, said in the release. “This is based on 100 years of science and we’re finally approaching a commercial product … We’re proud to lead this round and support Casimir’s journey from applied science to deployed technology.”

Casimir says it aims to scale its technology across the ”full power spectrum,” including large-scale energy systems that can power homes, commercial infrastructures and electric vehicles.

Casimir's scientific work has been supported by DARPA-funded nanofabrication research and its technology was incubated at the Limitless Space Institute (LSI). LSI is a nonprofit that works to innovate interstellar travel and was founded by Kam Ghaffarian. Technology investor and serial entrepreneur Ghaffarian has been behind companies like X-energy, Intuitive Machines, Axiom Space and Quantum Space.

Harold “Sonny” White, founder and CEO of Casimir, believes the technology can power devices for years without replacements.

“Millions of devices will operate for years without a battery ever needing to be replaced or recharged because we have engineered a customized Casimir cavity into hardware capable of producing persistent electrical power,” White added in the release. “I spent nearly two decades at NASA studying how we power humanity’s future. That work led me to the Casimir effect and the quantum vacuum, where new tools have allowed us to build on a century of scientific knowledge and bring abundant power to the world.”

Electric truck charging network expands to Houston-Dallas freight corridor

electric trucking

Greenlane Infrastructure, an electric public charging station developer and operator, is expanding outside of its home state of California and into Texas.

The Santa Monica-based company plans to launch its high-power charging sites along the Dallas–Houston I-45 corridor, which is one of the highest-volume commercial trucking routes in the country, according to a news release from Greenlane.

The sites will feature 6-8 pull-through lanes with chargers supporting combined charging system (CCS) and megawatt charging system (MCS) connectors that allow electric truck drivers to recharge their vehicles during standard rest periods. They will also offer tractor parking and charging, as well as operations that will allow for overnight stops.

Drivers can reserve chargers in advance, monitor charging activity in real time, and manage billing from the Greenlane Edge platform.

“Our customers are making commitments to electrify their fleets, and they need a charging network that can grow alongside them,” Patrick Macdonald-King, CEO of Greenlane, said in the release. “This is the first leg of the Texas triangle, one of the more important freight arteries in the country, so bringing high-power charging there is the next logical step in building a network that serves how freight moves across America.”

Greenlane is also expanding across the West Coast, with five locations under development in California and Nevada. It opened its flagship Greenlane Center in Colton, California, in April 2025. The company plans to open locations in Blythe, California, and Port of Long Beach this year.

Greelane was founded in 2023 as a joint venture between Daimler Truck North America, NextEra Energy Resources and BlackRock. It has secured partnerships with electric long-haul truck developer Windrose Technology, Velocity Truck Centers and Volvo Trucks North America.
