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.

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.

Austin energy startup expands to Houston, offering electricity with backup batteries

power move

An Austin startup that sells electricity and couples it with backup power has entered the Houston market.

Base Power, which claims to be the first and only electricity provider to offer a backup battery, now serves the Houston-area territory served by Houston-based CenterPoint Energy. No solar equipment is required for Base Power’s backup batteries.

The company is initially serving customers in the Cy-Fair, Spring, Cinco Ranch and Mission Bend communities, and will expand to other Houston-area places in the future.

Base Power already serves customers in the Austin and Dallas-Fort Worth markets.

The company says it provides “a cost-effective alternative to generators and solar-battery systems in an increasingly unreliable power grid.”

“Houston represents one of the largest home backup markets in the world, largely due to dramatic weather events that strain the power grid,” says Base Power co-founder and CEO Zach Dell, son of Austin tech billionaire Michael Dell. “We’re eager to provide an accessible energy service that delivers affordable, reliable power to Houston homeowners.”

After paying a $495 or $995 fee that covers installation and permitting, and a $16- or $29-per-month membership fee, Base Power customers gain access to a backup battery and competitive energy rates, the company says. The startup is waiving the $495 setup fee for the first 500 Houston-area homeowners who sign up and make a refundable deposit.

With the Base Power backup package, electricity costs 14.3 cents per kilowatt-hour, which includes Base Power’s 8.5 cents per kilowatt-hour charge and rates charged by CenterPoint. The average electric customer in Houston pays 13 cents per kilowatt-hour, according to EnergySage.

“Base Power is built to solve a problem that so many Texans face: consistent power,” says Justin Lopas, co-founder and chief operating officer of Base Power and a former SpaceX engineer. “Houstonians can now redefine how they power their homes, while also improving the existing power grid.”

Founded in 2023, Base Power has attracted funding from investors such as Thrive Capital, Valor Equity Partners, Altimeter Capital, Trust Ventures, and Terrain. Zach Dell was previously an associate on the investment team at Thrive Capital.

Energy expert: What 2025 revealed about the evolution of Texas power

guest column

2025 marked a pivotal year for Texas’ energy ecosystem. Rising demand, accelerating renewable integration, tightening reserve margins and growing industrial load reshaped the way policymakers, utilities and the broader market think about reliability.

This wasn’t just another year of operational challenges; it was a clear signal that the state is entering an era where growth and innovation must move together in unison if Texas is going to keep pace.

What happened in 2025 is already influencing the decisions utilities, regulators and large energy consumers will make in 2026 and beyond. If Texas is going to remain the nation’s proving ground for large-scale energy innovation, this year made one thing clear: we need every tool working together and working smarter.

What changed: Grid, policy & the growth of renewables

This year, ERCOT recorded one of the steepest demand increases in its history. From January through September 2025, electricity consumption reached 372 terawatt-hours (TWh), a 5 percent increase over the previous year and a 23 percent jump since 2021. That growth officially positions ERCOT as the fastest-expanding large grid in the country.

To meet this rising load, Texas leaned heavily on clean energy. Solar, wind and battery storage served approximately 36 percent of ERCOT’s electricity needs over the first nine months of the year, a milestone that showcased how quickly Texas has diversified its generation mix. Utility-scale solar surged to 45 TWh, up 50 percent year-over-year, while wind generation reached 87 TWh, a 36 percent increase since 2021.

Battery storage also proved its value. What was once niche is now essential: storage helped shift mid-day excess solar to evening peaks, especially during a historic week in early spring when Texas hit new highs for simultaneous wind, solar and battery output.

Still, natural gas remained the backbone of reliability. Dispatchable thermal resources supplied more than 50 percent of ERCOT’s power 92 percent of the time in Q3 2025. That dual structure of fast-growing renewables backed by firm gas generation is now the defining characteristic of Texas’s energy identity.

But growth cuts both ways. Intermittent generation is up, yet demand is rising faster. Storage is scaling, but not quite at the rate required to fill the evening reliability gap. And while new clean-energy projects are coming online rapidly, the reality of rising population, data center growth, electrification and heavy industrial expansion continues to outpace the additions.

A recent forecast from the Texas Legislative Study Group projects demand could climb another 14 percent by mid-2026, tightening reserve margins unless meaningful additions in capacity, or smarter systemwide usage, arrive soon.

What 2025 meant for the energy ecosystem

The challenges of 2025 pushed Texas to rethink reliability as a shared responsibility between grid operators, generation companies, large load customers, policymakers and consumers. The year underscored several realities:

1. The grid is becoming increasingly weather-dependent. Solar thrives in summer; wind dominates in spring and winter. But extreme heat waves and cold snaps also push demand to unprecedented levels. Reliability now hinges on planning for volatility, not just averages.

2. Infrastructure is straining under rapid load growth. The grid handled multiple stress events in 2025, but it required decisive coordination and emerging technologies, such as storage methods, to do so.

3. Innovation is no longer optional. Advanced forecasting, grid-scale batteries, demand flexibility tools, and hybrid renewable-gas portfolios are now essential components of grid stability.

4. Data centers and industrial electrification are changing the game. Large flexible loads present both a challenge and an opportunity. With proper coordination, they can help stabilize the grid. Without it, they can exacerbate conditions of scarcity.

Texas can meet these challenges, but only with intentional leadership and strong public-private collaboration.

The system-level wins of 2025

Despite volatility, 2025 showcased meaningful progress:

Renewables proved their reliability role. Hitting 36 percent of ERCOT’s generation mix for three consecutive quarters demonstrates that wind, solar and batteries are no longer supplemental — they’re foundational.

Storage emerged as a real asset for reliability. Battery deployments doubled their discharge records in early 2025, showing the potential of short-duration storage during peak periods.

The dual model works when balanced wisely. Natural gas continues to provide firm reliability during low-renewable hours. When paired with renewable growth, Texas gains resilience without sacrificing affordability.

Energy literacy increased across the ecosystem. Communities, utilities and even industrial facilities are paying closer attention to how loads, pricing signals, weather and grid conditions interact—a necessary cultural shift in a fast-changing market.

Where Texas goes in 2026

Texas heads into 2026 with several unmistakable trends shaping the road ahead. Rate adjustments will continue as utilities like CenterPoint request cost recovery to strengthen infrastructure, modernize outdated equipment and add the capacity needed to handle record-breaking growth in load.

At the same time, weather-driven demand is expected to stay unpredictable. While summer peaks will almost certainly set new records, winter is quickly becoming the bigger wild card, especially as natural gas prices and heating demand increasingly drive both reliability planning and consumer stress.

Alongside these pressures, distributed energy is set for real expansion. Rooftop solar, community battery systems and hybrid generation-storage setups are no longer niche upgrades; they’re quickly becoming meaningful grid assets that help support reliability at scale.

And underlying all of this is a cultural shift toward energy literacy. The utilities, regulators, businesses, and institutions that understand load flexibility, pricing signals and efficiency strategies will be the ones best positioned to manage costs and strengthen the grid. In a market that’s evolving this fast, knowing how we use energy matters just as much as knowing how much.

The big picture: 2025 as a blueprint for a resilient future

If 2025 showed us anything, it’s that Texas can scale innovation at a pace few states can match. We saw record renewable output, historic storage milestones and strong thermal performance during strain events. The Texas grid endured significant stress but maintained operational integrity.

But it also showed that reliability isn’t a static achievement; it’s a moving target. As population growth, AI and industrial electrification and weather extremes intensify, Texas must evolve from a reactive posture to a proactive one.

The encouraging part is that Texas has the tools, the talent and the market structure to build one of the most resilient and future-ready power ecosystems in the world. The test ahead isn’t whether we can generate enough power; it’s whether we can coordinate systems, technologies and market behavior fast enough to meet the moment.

And in 2026, that coordination is precisely where the opportunity lies.

Blackstone clears major step in acquisition of TXNM Energy

power deal

A settlement has been reached in a regulatory dispute over Blackstone Infrastructure’s pending acquisition of TXNM Energy, the parent company of Texas-New Mexico Power Co. , which provides electricity in the Houston area. The settlement still must be approved by the Public Utility Commission of Texas.

Aside from Public Utility Commission staffers, participants in the settlement include TXNM Energy, Texas cities served by Texas-New Mexico Power, the Texas Office of Public Utility Counsel, Texas Industrial Energy Consumers, Walmart and the Texas Energy Association for Marketers.

Texas-New Mexico Power, based in the Dallas-Fort Worth suburb of Lewisville, supplies electricity to more than 280,000 homes and businesses in Texas. Ten cities are in Texas-New Mexico Power’s Houston-area service territory:

  • Alvin
  • Angleton
  • Brazoria
  • Dickinson
  • Friendswood
  • La Marque
  • League City
  • Sweeny
  • Texas City
  • West Columbia

Under the terms of the settlement, Texas-New Mexico Power must:

  • Provide a $45.5 million rate credit to customers over 48 months, once the deal closes
  • Maintain a seven-member board of directors, including three unaffiliated directors as well as the company’s president and CEO
  • Embrace “robust” financial safeguards
  • Keep its headquarters within the utility’s Texas service territory
  • Avoid involuntary layoffs, as well as reductions of wages or benefits related to for-cause terminations or performance issues

The settlement also calls for Texas-New Mexico Power to retain its $4.2 billion five-year capital spending plan through 2029. The plan will help Texas-New Mexico Power cope with rising demand; peak demand increased about 66 percent from 2020 to 2024.

Citing the capital spending plan in testimony submitted to the Public Utility Commission, Sebastian Sherman, senior managing director of Blackstone Infrastructure, said Texas-New Mexico Power “needs the right support to modernize infrastructure, to strengthen the grid against wildfire and other risks, and to meet surging electricity demand in Texas.”

Blackstone Infrastructure, which has more than $64 billion in assets under management, agreed in August to buy TXNM Energy in a $11.5 billion deal.

Neal Walker, president of Texas-New Mexico Power, says the deal will help his company maintain a reliable, resilient grid, and offer “the financial resources necessary to thrive in this rapidly changing energy environment and meet the unprecedented future growth anticipated across Texas.”

Constellation and Calpine's $26B clean energy megadeal clears final regulatory hurdle

big deal

Baltimore-based nuclear power company Constellation Energy Corp. received final regulatory clearance this month to acquire Houston-based Calpine Corp. for a net purchase price of $26.6 billion.

The acquisition has the potential to create America’s “largest clean energy provider,” the companies reported when the deal was first announced in January.

The Department of Justice approved the acquisition contingent on Calpine divesting several assets, including one in the Houston area.

The company agreed to divest the Jack Fusco Energy Center natural gas-fired combined cycle facility in Richmond, Texas; four generating assets in the Mid-Atlantic region; and other natural gas plants in Pennsylvania and Corpus Christi, Texas.

The Federal Energy Regulatory Commission, the Public Utility Commission of Texas and the New York Public Service Commission previously approved the deal. The companies can move toward closing the acquisition once the court finalizes the stipulation and order.

"We are very pleased to reach a settlement that allows us to bring together two magnificent companies to create a new Constellation with unprecedented scale, talent and capability to better serve our customers and communities while building the foundation for America’s next great era of growth and innovation," Joe Dominguez, president and CEO of Constellation, said in a news release. "We thank the Department for its professionalism and tireless work reviewing this transaction through these many months. It’s now time for us to complete the transaction, welcome our new colleagues from Calpine, and together begin our journey to light the way to a brilliant tomorrow for all."

Andrew Novotny, CEO of Calpine, will continue to lead the Calpine business and Constellation's fleet of natural gas, hydro, solar and wind generation, according to the company. He will report to Dominguez and also serve as senior executive vice president of Constellation Power Operations.

Constellation is considered one of the top clean energy producers in the U.S. Earlier this month, the company was approved to receive a $1 billion loan from the Department of Energy's Energy Dominance Financing Program to restart its 835-megawatt nuclear reactor in Pennsylvania known as Crane Clean Energy Center.

"Work to restart the reactor comes at a time of unprecedented electric demand growth from electrification and the new data centers needed to support a growing digital economy and to help America win the AI race," a news release from the company reads. "Crane will support grid stability by delivering reliable, around-the-clock electric supply."
