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.

How Corrolytics is tackling industrial corrosion and cutting emissions

now streaming

Corrosion is not something most people think about, but for Houston's industrial backbone pipelines, refineries, chemical plants, and water infrastructure, it is a silent and costly threat. Replacing damaged steel and overusing chemicals adds hundreds of millions of tons of carbon emissions every year. Despite the scale of the problem, corrosion detection has barely changed in decades.

In a recent episode of the Energy Tech Startups Podcast, Anwar Sadek, founder and CEO of Corrolytics, explained why the traditional approach is not working and how his team is delivering real-time visibility into one of the most overlooked challenges in the energy transition.

From Lab Insight to Industrial Breakthrough

Anwar began as a researcher studying how metals degrade and how microbes accelerate corrosion. He quickly noticed a major gap. Companies could detect the presence of microorganisms, but they could not tell whether those microbes were actually causing corrosion or how quickly the damage was happening. Most tests required shipping samples to a lab and waiting months for results, long after conditions inside the asset had changed.

That gap inspired Corrolytics' breakthrough. The company developed a portable, real-time electrochemical test that measures microbial corrosion activity directly from fluid samples. No invasive probes. No complex lab work. Just the immediate data operators can act on.

“It is like switching from film to digital photography,” Anwar says. “What used to take months now takes a couple of hours.”

Why Corrosion Matters in Houston's Energy Transition

Houston's energy transition is a blend of innovation and practicality. While the world builds new low-carbon systems, the region still depends on existing industrial infrastructure. Keeping those assets safe, efficient, and emission-conscious is essential.

This is where Corrolytics fits in. Every leak prevented, every pipeline protected, and every unnecessary gallon of biocide avoided reduces emissions and improves operational safety. The company is already seeing interest across oil and gas, petrochemicals, water and wastewater treatment, HVAC, industrial cooling, and biofuels. If fluids move through metal, microbial corrosion can occur, and Corrolytics can detect it.

Because microbes evolve quickly, slow testing methods simply cannot keep up. “By the time a company gets lab results, the environment has changed completely,” Anwar explains. “You cannot manage what you cannot measure.”

A Scientist Steps Into the CEO Role

Anwar did not plan to become a CEO. But through the National Science Foundation's ICorps program, he interviewed more than 300 industry stakeholders. Over 95 percent cited microbial corrosion as a major issue with no effective tool to address it. That validation pushed him to transform his research into a product.

Since then, Corrolytics has moved from prototype to real-world pilots in Brazil and Houston, with early partners already using the technology and some preparing to invest. Along the way, Anwar learned to lead teams, speak the language of industry, and guide the company through challenges. “When things go wrong, and they do, it is the CEO's job to steady the team,” he says.

Why Houston

Relocating to Houston accelerated everything. Customers, partners, advisors, and manufacturing talent are all here. For industrial and energy tech startups, Houston offers an ecosystem built for scale.

What's Next

Corrolytics is preparing for broader pilots, commercial partnerships, and team growth as it continues its fundraising efforts. For anyone focused on asset integrity, emissions reduction, or industrial innovation, this is a company to watch.
