Base Power raises B to reinvent Texas’ grid with home batteries

Austin-based Base Power just raised $1 billion in Series C funding to accelerate its mission to modernize the Texas grid, one home battery at a time.

Addition led the round, with support from existing and new investors. The fresh capital will help Base scale up operations, grow its team, and build out domestic manufacturing to meet surging demand for resilient, distributed home batteries.

Base Power is a licensed electricity provider operating in Texas’s deregulated electricity market, and it functions as a virtual power plant (VPP). Its model is simple but transformative: customers pay a monthly fee for energy, installation, and a home battery – no rooftop solar required. When the grid is up, Base’s networked batteries help stabilize it; when it goes down, the battery keeps the lights on at home.

“The chance to reinvent our power system comes once in a generation,” said Zach Dell, Base Power’s CEO and cofounder. “We’re scaling the team to make our abundant energy future a reality.”

In under two years, Base has already deployed more than 100 megawatt-hours (MWh) of residential battery capacity, making it one of the fastest-growing distributed energy platforms in the US. The company’s rapid growth has been fueled by organic customer demand, partnerships with major homebuilders like Lennar, and collaborations with forward-thinking utilities.

Base Power currently serves homeowners across the Dallas–Fort Worth, Houston, and Austin regions, and plans to expand nationwide. To support that growth, the company is building its first factory, an energy storage and power electronics manufacturing hub at the former Austin American-Statesman printing press site in downtown Austin.

The company also recently qualified for Texas’s Aggregated Distributed Energy Resource (ADER) program, which allows distributed batteries to participate directly in the grid market. That means extra reliability for the state and lower costs for customers through shared revenue from grid services.

“The only way to add capacity to the grid is by deploying hardware — and we need to make that here in the US, ourselves,” said Justin Lopas, Base’s COO and cofounder. “This factory in Austin is our first, and we’re already planning for our second. We’re building the tools and systems to reindustrialize America and reinvent the grid.”

Electrek’s Take

Texas’s grid struggles, from heatwaves to winter blackouts, make Base Power’s model timely. Linking home batteries to a virtual power plant offers home backup and grid support. (I was part of a VPP in Vermont, and I can’t stress enough how great it is, especially in power outages.)

With $1 billion in new funding and a planned Austin factory, Base aims to scale fast. For context, Tesla deployed over 31 GWh of storage in 2024, but that figure includes utility-scale Megapacks as well as residential Powerwalls because Tesla didn’t separate out the two in its report. Sunrun’s VPPs now include 20,000+ customers across nine states, and it supplies significant grid support in California. Base’s 100 MWh so far is much smaller, but as a licensed electricity provider, not just a technology platform, its focused Texas rollout and participation in the state’s ADER program could position it as a nimble challenger in the growing VPP space.
