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.”

Houston company acquired by private equity firm, plans to expand support of energy transition

M&A

A Houston-based infrastructure services platform has been acquired by an energy industry-focused private equity firm.

Saber Power Services announced last month that it has been acquired by an investor group led by Greenbelt Capital Management from funds managed by Oaktree Capital Management. The acquisition was in partnership with funds managed by Schroders Capital, StepStone Group, and Wafra Inc., according to the company's news release.

Saber, founded in 2010, is an electrical services firm that provides design, construction, testing, and maintenance services and solutions across the energy spectrum — renewables, battery storage, utility, industrial, and energy infrastructure markets. The company's customers are located throughout Texas and the Southeast.

“With over a decade of experience, the Saber Power team has demonstrated its ability to provide a safe, reliable and high-performance service offering that excels in complex environments," Brian Bratton, CEO of Saber, says in the release. "We are excited for Saber’s next chapter and believe this investment from Greenbelt demonstrates the market leading position of our business and our customers’ trust in the quality of our work."

The terms of the deal were not disclosed, but some of Saber’s management team will maintain ownership of a significant stake in the company, according to the news release. Greenbelt, the acquiring party, secured debt and equity financing from Blackstone Credit.

“We are excited to partner with Greenbelt and look forward to supporting Saber with the next phase of its growth," say Blackstone representatives in the release. "Blackstone Credit invests in market leading energy-transition companies and believes Saber is well-positioned to play an important role in this space.”

“The energy landscape is rapidly evolving as electrification trends continue to impact commercial and industrial end markets," Sam Graham, principal at Greenbelt, says. "Both physical assets and power markets will need to adapt to support load shifting, bi-directional power flows, and meaningfully increased power demand, all of which require increased grid complexity and strengthens demand for Saber’s specialized engineering, design, construction and maintenance services.”

Chris Murphy, partner at Greenbelt, adds that modernization of the grid is an important sector focus for the company.

"We believe Saber’s end-to-end service platform is critical to facilitate the growing penetration of distributed energy resources across the grid, as well as meet the increasing demands of mass-scale industrial electrification," he says. "We are thrilled to partner with Saber’s experienced and talented executive team and believe our history of investing across the new energy economy will allow us to help accelerate the Company’s growth.”

ERCOT approves $9.4B project to improve grid, meet data center demand

power project

The Electric Reliability Council of Texas, which manages the electric grid for 90 percent of Texans, is undertaking a $9.4 billion project to improve the reliability and efficiency of statewide power distribution. The initiative comes as ERCOT copes with escalating demand for electricity from data centers and cryptocurrency-mining facilities.

The project, approved Dec. 9 by ERCOT’s board, will involve building a 1,109-mile “super highway” of new 765-kilovolt transmission lines. One kilovolt equals 1,000 volts of electricity.

According to the Hoodline Dallas news site, the $9.4 billion project represents the five- to six-year first phase of ERCOT’s Strategic Transmission Expansion Plan (STEP). Hoodline says the plan, whose price tag is nearly $33 billion, calls for 2,468 miles of new 765-kilovolt power lines.

STEP will enable ERCOT to “move power longer distances with fewer losses,” Hoodline reports.

Upgrading the ERCOT grid is a key priority amid continued population growth in Texas, along with the state’s explosion of new data centers and cryptocurrency-mining facilities.

ERCOT says about 11,000 megawatts of new power generation capacity have been added to the ERCOT grid since last winter.

But in a report released ahead of the December board meeting, ERCOT says it received 225 requests this year from large power users to connect to its grid — a 270 percent uptick in the number of megawatts being sought by mega-users since last December. Nearly three-fourths (73 percent) of the requests came from data centers.

Allan Schurr, chief commercial officer of Houston-based Enchanted Rock, a provider of products and services for microgrids and onsite power generation, tells Energy Capital that the quickly expanding data center industry is putting “unprecedented pressure” on ERCOT’s grid.

“While the state has added new generation and transmission capacity, lengthy interconnection timelines and grid-planning limitations mean that supply and transmission are not keeping pace with this rapid expansion,” Schurr says. “This impacts both reliability and affordability.”

For families in Texas, this could result in higher energy bills, he says. Meanwhile, critical facilities like hospitals and grocery stores face a heightened challenge of preventing power outages during extreme weather or at other times when the ERCOT grid is taxed.

“I expect this trend to continue as AI and high-density computing grow, driving higher peak demand and greater grid variability — made even more complex by more renewables, extreme weather and other large energy users, like manufacturers,” Schurr says.

According to the Pew Research Center, data centers accounted for 4 percent of U.S. electricity use in 2024, and power demand from data centers is expected to more than double by 2030. Data centers that support the AI boom make up much of the rising demand.

In September, RBN Energy reported more than 10 massive data-center campuses had been announced in Texas, with dozens more planned. The Lone Star State is already home to roughly 400 data centers.

“Texas easily ranks among the nation’s top states for existing data centers, with only Virginia edging it out in both data-center count and associated power demand,” says RBN Energy.

Federal judge strikes Trump order blocking wind energy development

wind win

In a win for clean energy and wind projects in Texas and throughout the U.S., a federal judge struck down President Donald Trump’s “Day One” executive order that blocked wind energy development on federal lands and waters, the Associated Press reports.

Judge Patti Saris of the U.S. District Court for the District of Massachusetts vacated Trump’s executive order from Jan. 20, declaring it unlawful and calling it “arbitrary and capricious.”

The challenge was led by a group of state attorneys general from 17 states and Washington, D.C., which was led by New York Attorney General Letitia James. The coalition pushed back against Trump's order , arguing that the administration didn’t have the authority to halt project permitting, and that efforts would critically impact state economies, the energy industry, public health and climate relief efforts.

White House spokesperson Taylor Rogers told the Associated Press that wind projects were given unfair treatment during the Biden Administration and cited that the rest of the energy industry suffered from regulations.

According to the American Clean Power Association, wind is the largest source of renewable energy in the U.S. It provides 10 percent of the electricity generated—and growing. Texas leads the nation in wind electricity generation, accounting for 28 percent of the U.S. total in 2024, according to the U.S. Energy Information Administration.

Several clean-energy initiatives have been disrupted by recent policy changes, impacting Houston projects.

The Biden era Inflation Reduction Act’s 10-year hydrogen incentive was shortened under Trump’s One Big Beautiful Bill Act, prompting ExxonMobil to pause its Baytown low-carbon hydrogen project. That project — and two others in the Houston region — also lost federal support as part of a broader $700 million cancellation tied to DOE cuts.

Meanwhile, Texas House Democrats have urged the administration to restore a $250 million Solar for All grant that would have helped low-income households install solar panels.

Texas launches cryptocurrency reserve with $5 million Bitcoin purchase

Digital Deals

Texas has launched its new cryptocurrency reserve with a $5 million purchase of Bitcoin as the state continues to embrace the volatile and controversial digital currency.

The Texas Comptroller’s Office confirmed the purchase was made last month as a “placeholder investment” while the office works to contract with a cryptocurrency bank to manage its portfolio.

The purchase is one of the first of its kind by a state government, made during a year where the price of Bitcoin has exploded amid the embrace of the digital currency by President Donald Trump’s administration and the rapid expansion of crypto mines in Texas.

“The Texas Legislature passed a bold mandate to create the nation’s first Strategic Bitcoin Reserve,” acting Comptroller Kelly Hancock wrote in a statement. “Our goal for implementation is simple: build a secure reserve that strengthens the state’s balance sheet. Texas is leading the way once again, and we’re proud to do it.”

The purchase represents half of the $10 million the Legislature appropriated for the strategic reserve during this year’s legislative session, but just a sliver of the state’s $338 billion budget.

However, the purchase is still significant, making Texas the first state to fund a strategic cryptocurrency reserve. Arizona and New Hampshire have also passed laws to create similar strategic funds but have not yet purchased cryptocurrency.

Wisconsin and Michigan made pension fund investments in cryptocurrency last year.

The Comptroller’s office purchased the Bitcoin the morning of Nov. 20 when the price of a single bitcoin was $91,336, according to the Comptroller’s office. As of Friday afternoon, Bitcoin was worth slightly less than the price Texas paid, trading for $89,406.

University of Houston energy economist Ed Hirs questioned the state’s investment, pointing to Bitcoin’s volatility. That makes it a bad investment of taxpayer dollars when compared to more common investments in the stock and bond markets, he said.

“The ordinary mix [in investing] is one that goes away from volatility,” Hirs said. “The goal is to not lose to the market. Once the public decides this really has no intrinsic value, then it will be over, and taxpayers will be left holding the bag.”

The price of Bitcoin is down significantly from an all-time high of $126,080 in early October.

Lee Bratcher, president of the Texas Blockchain Council, argued the state is making a good investment because the price of Bitcoin has trended upward ever since it first launched in early 2009.

“It’s only a 16-year-old asset, so the volatility, both in the up and down direction, will smooth out over time,” Bratcher said. “We still want it to retain some of those volatility characteristics because that’s how we could see those upward moves that will benefit the state’s finances in the future.”

Bratcher said the timing of the state’s investment was shrewd because he believes it is unlikely to be valued this low again.

The investment comes at a time that the crypto industry has found a home in Texas.

Rural counties have become magnets for crypto mines ever since China banned crypto mining in 2021 and Gov. Greg Abbott declared “Texas is open for crypto business” in a post on social media.

The state is home to at least 27 Bitcoin facilities, according to the Texas Blockchain Council, making it the world’s top crypto mining spot. The two largest crypto mining facilities in the world call Texas home.

The industry has also come under criticism as it expands.

Critics point to the industry’s significant energy usage, with crypto mines in the state consuming 2,717 megawatts of power in 2023, according to the comptroller’s office. That is enough electricity to power roughly 680,000 homes.

Crypto mines use large amounts of electricity to run computers that run constantly to produce cryptocurrencies, which are decentralized digital currencies used as alternatives to government-backed traditional currencies.

A 2023 study by energy research and consulting firm Wood Mackenzie commissioned by The New York Times found that Texans’ electric bills had risen nearly 5%, or $1.8 billion per year, due to the increase in demand on the state power grid created by crypto mines.

Residents living near crypto mines have also complained that the amount of job creation promised by the facilities has not materialized and the noise of their operation is a nuisance.

“Texas should be reinvesting Texan’s tax money in things that truly bolster the economy long term, living wage, access to quality healthcare, world class public schools,” said state Sen. Molly Cook, D-Houston, who voted against the creation of the strategic fund. “Instead it feels like they’re almost gambling our money on something that is known to be really volatile and has not shown to be a tide that raises all boats.”

State Sen. Charles Schwertner, R-Georgetown, who authored the bill that created the fund, said at the time it passed that it will allow Texas to “lead and compete in the digital economy.”
