Austin-based startup Base Power, which offers battery-supported energy in the Houston area and other regions, has raised $1 billion in series C funding—making it one of the largest venture capital deals this year in the U.S.

VC firm Addition led the $1 billion round. All of Base Power’s existing major investors also participated, including Trust Ventures, Valor Equity Partners, Thrive Capital, Lightspeed Venture Partners, Andreessen Horowitz (a16z), Altimeter, StepStone Group, 137 Ventures, Terrain, Waybury Capital, and entrepreneur Elad Gil. New investors include Ribbit Capital, Google-backed CapitalG, Spark Capital, Bond, Lowercarbon Capital, Avenir Growth Capital, Glade Brook Capital Partners, Positive Sum and 1789 Capital Management.

Coupled with the new $1 billion round, Base Power has hauled in more than $1.27 billion in funding since it was founded in 2023.

Base Power supplies power to homeowners and the electric grid through a distributed storage network.

“The chance to reinvent our power system comes once in a generation,” Zach Dell, co-founder and CEO of Base Power, said in a news release. “The challenge ahead requires the best engineers and operators to solve it, and we’re scaling the team to make our abundant energy future a reality.”

Zach Dell is the son of Austin billionaire and Houston native Michael Dell, chairman and CEO of Round Rock-based Dell Technologies.

In less than two years, Base Power has developed more than 100 megawatt-hours of battery-enabled storage capacity. One megawatt-hour represents one hour of energy use at a rate of one million watts.

Base Power recently expanded its service to the city of Houston. It already was delivering energy to several other communities in the Houston area. To serve the Houston region, the startup has opened an office in Katy.

The startup also serves the Dallas-Fort Worth and Austin markets. At some point, Base Power plans to launch a nationwide expansion.

To meet current and future demand, Base Power is building its first energy storage and power electronics factory at the former downtown Austin site of the Austin American-Statesman’s printing presses.

“We’re building domestic manufacturing capacity for fixing the grid,” Justin Lopas, co-founder and chief operating officer of Base Power, added in the release. “The only way to add capacity to the grid is [by] physically deploying hardware, and we need to make that here in the U.S. ... This factory in Austin is our first, and we’re already planning for our second.”

Austin energy startup Base Power opens Katy office & expands Houston service

power move

An Austin startup that pairs electricity with backup power has started doing business in Houston.

Base Power announced this spring that it was entering the Houston market, with an initial focus on Cy-Fair, Spring, Cinco Ranch and Mission Bend. Now, Base Power is offering its service to households within the city of Houston.

To support its growth in the Houston area, Base Power has opened an office and warehouse in Katy. More than 30 people now work there. Plans to expand the Katy location are underway.

Base Power provides electricity that’s complemented by home backup power. Homes don’t need to be using solar power to sign up for Base Power’s service.

The startup said its service automatically supplies power to a home when the electric grid fails.

“Unlike traditional backup systems with high upfront costs, Base earns revenue by providing services to the grid — enabling Houstonians to get reliable backup and real savings,” Base Power said.

In addition to its standard service, Base Power has begun offering technology known as the Generator Recharge Port. This component allows a portable generator to plug into the Base battery system to recharge batteries during extended power outages.

“Houston has long been the energy capital of Texas, yet it has also endured some of the nation’s most painful lessons about unreliable power,” said Zach Dell, co-founder and CEO of Base Power. “We see Houston not just as a place to expand, but as a proving ground for how the future of energy should work — resilient, dependable, and built to serve homeowners when it matters most.”

Dell is the only son of Austin tech billionaire Michael Dell, a Houston native.

Base Power’s expansion in Houston adds to its Texas presence. The company now serves homeowners in the Houston, Dallas-Fort Worth and Austin areas. A partnership with homebuilder Lennar and collaborations with two utilities, GVEC and the Bandera Electric Cooperative, are helping drive Base Power’s business.

Base Power has raised more than $270 million in funding since its founding in 2023. This includes a $200 million series B round that will help finance construction of the company’s first factory in Texas and help fuel Base Power’s national expansion.

The startup’s investors include Andreessen Horowitz, Lightspeed Venture Partners, Valor Equity Partners, Thrive Capital, Altimeter, Terrain and Trust.

Texas energy startup closes $200M round to fund first factory in the state

fresh funding

Base Power, an Austin-based startup that provides battery-powered home energy services and just entered the Houston market, has raised $200 million in series B funding.

The money will help finance the construction of Base Power’s first factory in Texas. A site for the factory hasn’t been announced. The cash will also go toward the national expansion of Base Power’s services.

Andreessen Horowitz, Lightspeed Venture Partners and Valor Equity Partners co-led the round, with participation from existing investors such as Thrive Capital, Altimeter, Terrain, and Trust.

As part of the fundraising, Lee Fixel of Addition and Antonio Gracias of Valor Equity Partners are joining Base Power’s board of directors.

Last year, the startup landed $68 million in a series A funding round.

Base Power, founded in 2023, specializes in developing battery storage for energy that it provides to residential customers. Its partners include homebuilder Lennar and the Bandera Electric Cooperative, which supplies power to customers in seven Hill Country counties. Earlier this year it began serving the Houston-area territory serviced by CenterPoint Energy.

“Our rapid expansion has allowed us to power up thousands of Texans in just a few months, while driving their energy costs down and power reliability up,” Zach Dell, co-founder and CEO of Base Power, says in a news release. “With this investment, we will continue to innovate on new grid solutions, establish our domestic manufacturing capabilities, and accelerate adoption nationally.”

Dell’s father is Austin tech billionaire Michael Dell. He founded the company with Justin Lopas.

ExxonMobil expands Gulf Coast CCS business with Louisiana deal

carbon contract

Spring-based energy powerhouse ExxonMobil has picked up another project in the carbon capture and storage (CCS) market.

Natural gas pipeline operator Williams Cos. has tapped ExxonMobil to transport and store up to one metric ton per year of CO2 from Williams’ natural gas collection and processing plant in southwest Louisiana’s Haynesville Shale.

Williams will transport natural gas via its Louisiana Energy Gateway pipeline, then process the natural gas and deliver it to the Gulf Coast for export as liquefied natural gas (LNG). The LNG will be used in power generation, residential and commercial heating, and industrial processes.

Williams recently agreed to acquire Momentum Midstream for up to $5.5 billion to expand Williams’ LNG presence in the Haynesville Shale. Haynesville is the country’s third-largest producer of natural gas.

Once the deal closes, Williams will own a $1.5 billion project in southwest Louisiana that will expand capacity of the Transco natural gas distribution system. The system serves power and LNG-export customers. Williams will also gain over 4,000 miles of pipeline and more than one million acres.

While Williams is based in Tulsa, Oklahoma, it has a significant presence in Houston. Last month, Green Street’s Real Estate Alert reported Williams bought the 64-story, 1.4 million-square-foot Williams Tower south of The Galleria from Invesco Real Estate for more than $300 million. The company will occupy about 360,000 square feet in the skyscraper for its Houston hub.

Williams employs about 800 people in Bayou City, including roughly 700 who work at Williams Tower, and plans to hire another 100 by the end of this year.

The Williams deal is ExxonMobil’s seventh CCS contract. ExxonMobil’s CCS portfolio supports LNG, lower-carbon-intensity steel, ammonia, natural gas processing, industrial gases and methanol.

ExxonMobil has established a “carbon superhighway” along the Gulf Coast to fuel its CCS business. The company owns and operates a more than 1,300-mile CO2 pipeline system, the largest in the U.S.

“Carbon capture is becoming an increasingly important part of industrial operations, but capture alone doesn’t solve the problem of high emissions,” says ExxonMobil. “What matters next is how CO2 is transported, used, and stored.”

ExxonMobil’s CCS initiatives are aimed at capturing a chunk of the rapidly growing CCS market in the U.S. Straits Research forecasts the market will grow from $5.66 billion this year to $13.56 billion by 2034.

“It’s not every day you get to witness the birth of a new American industry, but that’s exactly what’s happening right now at the U.S. Gulf Coast,” Dominic Genetti, senior vice president of CCS at ExxonMobil, wrote in an article published last year on the company’s website.

Fervo Energy, Mercury Fund leaders named first experts in residence for TEX-E

energy mentors

Two leading companies in Houston's clean energy scene have been named the Texas Exchange for Energy & Climate Entrepreneurship's first experts in residence.

TEX-E announced this month that Houston-based geothermal unicorn Fervo Energy and venture capital firm Mercury Fund have joined the nonprofit's new Expert-in-Residence partnership. The program aims to connect TEX-E Fellows with "the people and organizations shaping the future of energy and entrepreneurship."

The 2026 TEX-E Fellows were named in June and include 67 students from six Texas universities and the Massachusetts Institute of Technology. Nineteen are from Houston universities. See the full list here.

Through the Expert-in-Residence program, fellows will be able to network and work with:

"More than anything, students need the determination and creativity to step outside of their comfort zones and tackle problems that lack clear answers. At Fervo, we've consistently bet on young people who lack traditional 'hard skills' but are willing to embrace uncertainty and learn on the job. That open-mindedness will take students far," Jewett said in a prepared statement. Fervo named Jewett as COO in June.

TEX-E was founded in 2022 through partnerships with MIT Martin Trust Center for Entrepreneurship and Greentown Labs. It works with university students from six schools: Rice University, University of Houston, Prairie View A&M University, The University of Texas at Austin, Texas A&M University and MIT.

The organization named Houston venture capital and innovation leader Sandy Guitar as its new executive director last year. Guitar previously served as general partner and managing director at Houston-based VC firm HX Venture Fund and is co-founder of Weathergage Capital.

TEX-E is known for its student track within the Energy Venture Day and Pitch Competition at CERAWeek. It awarded $50,000 to student teams from the University of Texas and Rice University. Read more here.

BP to sell Houston’s Archaea Energy after $4.1 billion bet on biogas

RNG exit

Oil and gas conglomerate BP is unloading its Houston-based U.S. renewable natural gas business just four years after buying it.

The British company announced the planned sale of Archaea during its most recent earnings call but offered few details.

On the call, BP’s new CEO, Meg O’Neill, said her company had put Archaea on the market and already had attracted interest from potential buyers. BP acquired Houston-based Archaea Energy, the country’s largest producer of renewable natural gas (RNG), in 2022 for about $4.1 billion.

BP, whose North American headquarters is in Houston, is streamlining its portfolio. As such, O’Neill said Archaea represents a “capital intense” approach to biogas instead of the “capital light” approach BP now favors.

“If there’s somebody who sees an opportunity to create additional value, who will invest in that business, who will build on the foundation, because our team has made really good progress in improving the profitability of that business, then that will be a good outcome,” O’Neill told Wall Street analysts.

The proposed sale of Archaea is part of BP’s effort to sell about $20 billion in assets by the end of next year.

Archaea captures biogas, a natural byproduct of waste decomposition at landfills and dairy farms, and converts it into electricity or RNG. This process leads to cleaner air, less odor, and more sustainable energy than traditional fossil fuels.

Archaea was slated to be a cornerstone of BP’s plan to boost its biogas supply by roughly 600 percent to the equivalent of about 70,000 barrels of oil per day.

Bioenergy had been identified as one of bp’s five pillars of its multibillion-dollar energy transition initiative.

Another pillar: EV charging. Last month, BP agreed to sell its EV charging business in Austria to Switzerland’s Volenergy, along with 250 BP-branded stores and a fleet of business vehicles.

“By concentrating our capital on the assets and markets where BP can be most competitive and best serve customers, we are strengthening our balance sheet and creating a stronger downstream portfolio,” Richard Harding, interim executive vice president of downstream at BP, said of the Volenergy deal.
