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.

Houston energy and innovation leaders come together at Argonne National Laboratory

The view from heti

Nearly 20 companies from Houston, ranging from global multinationals to innovative startups, joined the team at Argonne National Laboratory in Lemont, Illinois, for a full day of meetings, discussions, and networking focused on advancing innovation, commercialization, and industry collaboration.

The fly-in organized by the Houston Energy Transition Initiative, provided a unique opportunity for companies to engage directly with Argonne researchers, technical experts, and leadership while gaining a deeper understanding of the laboratory’s world-class capabilities. Participants explored how national laboratories can help bridge the gap between breakthrough research and commercial deployment, particularly in areas critical to U.S. competitiveness and economic growth.

The significance of this engagement extends beyond a single visit. While the U.S. Department of Energy operates 17 national laboratories, none is located along the Gulf Coast, a region uniquely home to industry, infrastructure, and energy systems at commercial scale. HETI’s continued work with the national laboratories helps bridge that geographic and operational gap by connecting world-class scientific research with companies that understand how to scale and deploy technologies. The Argonne fly-in also created space to address practical barriers to collaboration, including complex agreements and lengthy contracting timelines, and to explore ways to establish partnership frameworks more efficiently.

Explore HETI’s key takeaways from the fly-in:

1. Scaling Technologies for Commercial Use

A central theme was the importance of scale-up infrastructure and the role Argonne plays in helping companies reduce technical and manufacturing risks. Participants learned how facilities such as the Materials Engineering Research Facility (MERF) support the transition from laboratory discoveries to pilot-scale production and ultimately commercial manufacturing. These capabilities are especially valuable for companies working to move promising technologies from concept to market.

The discussions also highlighted Argonne’s extensive work in critical materials, battery recycling, advanced manufacturing, and supply chain resilience. Attendees learned about initiatives including the ReCell Center, AI-enabled materials discovery, and advanced modeling tools that can help businesses understand supply chain vulnerabilities and evaluate mitigation strategies. These capabilities have applications across energy, chemicals, manufacturing, semiconductors, defense, and emerging technologies.

2. Creating Pathways for Collaboration

Another key takeaway was the importance of engaging early. Companies do not need to arrive with a fully developed project or solution. Argonne offers multiple pathways for collaboration, including sponsored research, user facility access, technology licensing, pilot-scale testing, and Cooperative Research and Development Agreements (CRADAs). These partnerships help companies access specialized expertise, facilities, and analytical tools that can accelerate innovation and commercialization

3. Building Connections Across Industry and Research

The fly-in reinforced the value of relationship building. Bringing together nearly 20 organizations in one place created meaningful opportunities for collaboration, knowledge sharing, and identifying future projects.

The conversations throughout the day demonstrated a shared commitment to strengthening domestic innovation, developing resilient supply chains, and creating pathways to bring new technologies to market.

Fervo produces first geothermal power at flagship Utah project

energy milestone

Fervo Energy’s flagship project in Utah just generated its first geothermal power.

The electricity is now flowing to the power grid from one of Cape Station’s three generation units, Houston-based Fervo said in a news release. This represents an early but important milestone for the project, as the unit isn’t scheduled to deliver contracted power until Oct. 1.

The achievement, coming four months after Fervo’s roughly $2.2 billion IPO, demonstrates the viability of enhanced geothermal systems (EGS).

“This is a gamechanger for the geothermal industry. It establishes EGS as the defining new power generation technology of our time, and we believe it shows that the commercial and technical maturity of EGS is ready to meet the urgent need for reliable, clean power,” Tim Latimer, co-founder and CEO of Fervo, said in the release.

The plant’s two other units are scheduled to launch commercial operations on Jan. 1.

The three units make up the project’s 99-megawatt first phase. The next phase, which will add 400 megawatts of capacity, is under construction. The second phase is set to go online in 2028.

Altogether, Cape Station will provide more than 4 gigawatts of capacity, with 900 megawatts already spoken for. The 900 megawatts of contracted electricity would be enough to power nearly 1 million U.S. homes per year.

“Cape Station works because we treated the subsurface like an engineering challenge,” Jack Norbeck, co-founder and chief technology officer of Fervo, added in the release. “Years of drilling, completion design, subsurface modeling, and flow testing led to this moment, and this is the validation that matters most.”

Enhanced geothermal continuously draws on heat that’s deep underground, producing electricity around the clock regardless of weather or time of day. That makes it one of the only carbon-free resources capable of constant power delivery, which is critical for data centers and AI infrastructure.
