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.

Micro-nuclear reactor to launch next year at Texas A&M innovation campus

nuclear pilot

The Texas A&M University System and Last Energy plan to launch a micro-nuclear reactor pilot project next summer at the Texas A&M-RELLIS technology and innovation campus in Bryan.

Washington, D.C.-based Last Energy will build a 5-megawatt reactor that’s a scaled-down version of its 20-megawatt reactor. The micro-reactor initially will aim to demonstrate safety and stability, and test the ability to generate electricity for the grid.

The U.S. Department of Energy (DOE) fast-tracked the project under its New Reactor Pilot Program. The project will mark Last Energy’s first installation of a nuclear reactor in the U.S.

Private funds are paying for the project, which Robert Albritton, chairman of the Texas A&M system’s board of regents, said is “an example of what’s possible when we try to meet the needs of the state and tap into the latest technologies.”

Glenn Hegar, chancellor of the Texas A&M system, said the 5-megawatt reactor is the kind of project the system had in mind when it built the 2,400-acre Texas A&M-RELLIS campus.

The project is “bold, it’s forward-looking, and it brings together private innovation and public research to solve today’s energy challenges,” Hegar said.

As it gears up to build the reactor, Last Energy has secured a land lease at Texas A&M-RELLIS, obtained uranium fuel, and signed an agreement with DOE. Founder and CEO Bret Kugelmass said the project will usher in “the next atomic era.”

In February, John Sharp, chancellor of Texas A&M’s flagship campus, said the university had offered land at Texas A&M-RELLIS to four companies to build small modular nuclear reactors. Power generated by reactors at Texas A&M-RELLIS may someday be supplied to the Electric Reliability Council of Texas (ERCOT) grid.

Also in February, Last Energy announced plans to develop 30 micro-nuclear reactors at a 200-acre site about halfway between Lubbock and Fort Worth.

Rice University partners with Australian co. to boost mineral processing, battery innovation

critical mineral partnership

Rice University and Australian mineral exploration company Locksley Resources have joined together in a research partnership to accelerate the development of antimony processing in the U.S. Antimony is a critical mineral used for defense systems, electronics and battery storage.

Rice and Locksley will work together to develop scalable methods for extracting and utilizing antimony. Currently, the U.S. relies on imports for nearly all refined antimony, according to Rice.

Locksley will fund the research and provide antimony-rich feedstocks and rare earth elements from a project in the Mojave Desert. The research will explore less invasive hydrometallurgical techniques for antimony extraction and explore antimony-based materials for use in batteries and other energy storage applications.

“This strategic collaboration with Rice marks a pivotal step in executing Locksley’s U.S. strategy,” Nathan Lude, chairman of Locksley Resources, said in a news release. “By fast-tracking our research program, we are helping rebuild downstream capacity through materials innovation that the country urgently requires.”

Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Materials Science and Nanoengineering at Rice, is the principal investigator of the project.

“Developing scalable, domestic pathways for antimony processing is not only a scientific and engineering challenge but also a national strategic priority,” Ajayan said in the news release. “By combining Rice’s expertise in advanced materials with Locksley’s resources, we can address a critical supply chain gap and build collaborations that strengthen U.S. energy resilience.”

The Rice Advanced Materials Institute (RAMI) will play a major role in supporting the advancement of technology and energy-storage applications.

“This partnership aligns with our mission to lead in materials innovations that address national priorities,” Lane Martin, director of RAMI, said in a news release. “By working with Locksley, we are helping to build a robust domestic supply chain for critical materials and support the advancement of next-generation energy technologies.”

Expert examines how far Texas has come in energy efficiency

Guest Column

Texas leads the nation in energy production, providing about one-fourth of the country’s domestically produced primary energy. It is also the largest energy-consuming state, accounting for about one-seventh of the nation’s total energy use, and ranks sixth among the states in per capita energy consumption.

However, because Texas produces significantly more energy than it consumes, it stands as the nation’s largest net energy supplier. October marked National Energy Awareness Month, so this is an ideal time to reflect on how far Texas has come in improving energy efficiency.

Progress in Clean Energy and Grid Resilience

Texas continues to lead the nation in clean energy adoption and grid modernization, particularly in wind and solar power. With over 39,000 MW of wind capacity, Texas ranks first in the country in wind-powered electricity generation, now supplying more than 10% of the state’s total electricity.

This growth was significantly driven by the Renewable Portfolio Standard (RPS), which requires utility companies to produce new renewable energy in proportion to their market share. Initially, the RPS aimed to generate 10,000 MW of renewable energy capacity by 2025. Thanks to aggressive capacity building, this ambitious target was reached much earlier than anticipated.

Solar energy is also expanding rapidly, with Texas reaching 16 GW of solar capacity as of April 2024. The state has invested heavily in large-scale solar farms and supportive policies, contributing to a cleaner energy mix.

Texas is working to integrate both wind and solar to create a more resilient and cost-effective grid. Efforts to strengthen the grid also include regulatory changes, winterization mandates, and the deployment of renewable storage solutions.

While progress is evident, experts stress the need for continued improvements to ensure grid reliability during extreme weather events, when we can’t rely on the necessities for these types of energy sources to thrive. To put it simply, the sun doesn’t always shine, and the wind doesn’t always blow.

Federal Funding Boosts Energy Efficiency

In 2024, Texas received $22.4 million, the largest share of a $66 million federal award, from the U.S. Department of Energy’s Energy Efficiency Revolving Loan Fund Capitalization Grant Program.

The goal of this funding is to channel federal dollars into local communities to support energy-efficiency projects through state-based loans and grants. According to the DOE, these funds can be used by local businesses, homeowners, and public institutions for energy audits, upgrades, and retrofits that reduce energy consumption.

The award will help establish a new Texas-based revolving loan fund modeled after the state’s existing LoanSTAR program, which already supports cost-effective energy retrofits for public facilities and municipalities. According to the Texas Comptroller, as of 2023, the LoanSTAR program had awarded more than 337 loans totaling over $600 million.

In addition to expanding the revolving loan model, the state plans to use a portion of the DOE funds to offer free energy audit services to the public. The grant program is currently under development.

Building on this momentum, in early 2025, Texas secured an additional $689 million in federal funding to implement the Home Energy Performance-Based, Whole House (HOMES) rebate program and the Home Electrification and Application Rebate (HEAR) program.

This investment is more than five times the state’s usual energy efficiency spending. Texas’s eight private Transmission and Distribution Utilities typically spend about $110 million annually on such measures. The state will have multiple years to roll out both the revolving loan and rebate programs.

However, valuable federal tax incentives for energy-efficient home improvements are set to expire on December 31, 2025, including:

  • The Energy Efficiency Home Improvement Credit allows homeowners to claim up to $3,200 per year in federal income tax credits, covering 30% of the cost of eligible upgrades, such as insulation, windows, doors, and high-efficiency heating and cooling systems.
  • The Residential Clean Energy Credit provides a 30% income tax credit for the installation of qualifying clean energy systems, including rooftop solar panels, wind turbines, geothermal heat pumps, and battery storage systems.

As these incentives wind down, the urgency grows for Texas to build on the positive gains from the past several years despite reduced federal funding. The state has already made remarkable strides in clean energy production, grid modernization, and energy-efficiency investments, but the path forward requires a strategic and inclusive approach to energy planning. Through ongoing state-federal collaboration, community-driven initiatives, and forward-looking policy reforms, Texas can continue its progress, ensuring that future energy challenges are met with sustainable and resilient solutions.
