Solaris Assets has completed its acquisition of the majority of Sunnova Energy International’s residential solar assets. Houston-based Sunnova filed for Chapter 11 bankruptcy this summer after piling up billions of dollars in debt.

Meanwhile, Sunnova founder and former CEO John Berger has launched a Houston-based home energy services startup, Otovo USA, which just received more than $4 million in seed funding.

Solaris now owns Sunnova’s residential solar services platform and its solar generation and storage portfolio, along with leases, loans and power purchase agreements. Sunnova’s operations are being shifted to SunStrong Management, an Austin-based asset manager for the renewable energy sector.

“By bringing together SunStrong’s asset management expertise with Sunnova’s nationally scaled customer base, we are creating a stronger, more capable leader in the solar industry,” Brendon Merkley, CEO of SunStrong, said in a news release. “Our priority is to maintain the highest levels of service for customers as we expand our footprint as a premier solar asset servicer.”

In June, Sunnova sold its new-home business to homebuilder Lennar for $15.2 million and sold certain assets to investment firm Atlas SP Partners for $15 million.

As of December, Sunnova’s debt totaled nearly $10.7 billion, Reuters reported. Sunnova faced numerous challenges in its quest to survive, including higher interest rates, the reduction of solar incentives in California, and a shakeup in federal subsidies for renewable energy.

Sunnova filed for Chapter 11 bankruptcy in June. A month later, a bankruptcy judge approved the court-supervised sale of Sunnova. Solaris’ acquisition of Sunnova closed Sept. 3.

As SunStrong absorbs the bulk of Sunnova’s assets, Berger — who quit in March as Sunnova’s CEO — has formed a new business. He’s now the founder and CEO of Otovo USA, a partner of European residential power company Otovo.

Otovo USA offers solar power systems, solar batteries, standby generators, EV chargers, electric-load managers, and other power generation and management systems. Otovo’s AI-supported offerings are now available in Texas; the company plans to expand nationwide.

Otovo USA raised its seed funding from the EIC Rose Rock Venture Fund, which invests in energy startups.

“Otovo USA is here to help the millions of Americans with home energy services that are fed up with the complexities of warranties, juggling multiple vendors, and long repair times,” Berger said. The startup, he added, “is bringing customers what they really need: reliable power and a single partner accountable for keeping it up and running. It’s your power, backed by ours.”

The deadline to apply for the ATCE Startup Village Energy Startup Competition in Houston is fast approaching. Photo via atce.org

Global energy startup competition returns to Houston this fall

apply now

The Society of Petroleum Engineers' Annual Technical Conference and Exhibition (ATCE) takes place in Houston this fall, and with it comes its ATCE Startup Village Energy Startup Competition.

Held this year at the George R. Brown Convention Center on Oct. 21, the fast-paced pitch competition invites early stage, upstream technology ventures from around the world to present on their companies and technologies in front of venture capitalists, angel investors and industry leaders.

The deadline to apply for the competition is Friday, July 18. Apply here.

The ATCE Startup Village is a partnership between SPE and the Rice Alliance for Technology and Entrepreneurship. Ten primary finalists and two alternates are selected to participate in the competition, where they have the opportunity to win cash prizes and gain mentorship from industry leaders.

Finalists will present a seven-minute pitch, followed by an additional seven minutes of Q&A.

They will also have the opportunity to meet with a panel of industry experts during a private coaching session the week of Sept. 22. Winners will be announced at ATCE in Houston, and finalists and alternates will be notified in late August.

Judging is based on four main criteria:

Innovative technology
Commercial strategy and business plan
Market potential
Management team and advisors

The competition has awarded nearly $460,000 in prize money to startups through the competition to date, according to the ATCE's website. Past winners have come from Canada, France, the Netherlands, Brazil, Saudi Arabia and the United States.

Several Houston teams pitched at the 2024 competition during the 100th annual ATCE in New Orleans. The local teams included:

Decimetrix, led by CEO Alejandro Zotti, went on to win the Best in Show and People's Choice awards. Revolink Technology Company earned the Rising Star, or runner up, award.

Houston clean energy founder scores spot on Time's list of most influential leaders

what a coincidence

What do pop star Sabrina Carpenter and Houston geothermal energy founder Tim Latimer have in common? In addition to their successful summers in their respective industries, they both also were named influential leaders on the TIME100 Next list for 2024.

For the fifth year, Time magazine released the annual list that was established to honor influential leaders "who are not waiting long in life to make an impact," reads the announcement article, continuing, "TIME100 Next has no age requirements; its aim is to recognize that influence does not have them either, nor does leadership look like it once did."

Representing Houston, Latimer was selected for his work in geothermal energy innovation. His company, Fervo Energy, has reached numerous milestones over its seven years of existence, garnering partnerships with the likes of Google and Devon Energy and raising an estimated $531 million in venture capital investment. Last month, the company announced it received a $100 million bridge loan from an affiliate of Irvington, New York-based X-Caliber Rural Capital for the first phase of its ongoing Cape Station project, which is being touted as the world’s largest geothermal energy plant.

"At a time when emission reductions are vital, energy demand has surged to a record high as a boom in AI and data centers pushes our nation’s grid to the brink," writes Tom Steyer, co–executive chair of Galvanize Climate Solutions, which invests in Fervo Energy, in a Time article. "Leveraging multiple forms of renewable energy will be critical to meeting this demand and advancing the climate transition.

"One such solution is geothermal, which could eliminate close to 800 megatonnes of emissions annually by 2050," he continues. "Latimer uses fracking technology to supercharge the output of geothermal wells. Last year, in collaboration with Google, his startup piloted a first-of-its-kind commercial-scale power plant, and in November, the Nevada plant (Project Red) began pumping electricity into Google data centers. Getting juice to the grid is a key milestone for energy startups—and one many never reach."

In an interview with InnovationMap for the Houston Innovators Podcast, Latimer reported that Fervo is growing and scaling at around a 100x pace. While Fervo's first project, Project Red, included three wells, Project Cape, a Southwest Utah site, will include around 100 wells with significantly reduced drilling cost and an estimated 2026 delivery. Latimer says there are a dozen other projects like Project Cape that are in the works.

"It's a huge ramp up in our drilling, construction, and powerplant programs from our pilot project, but we've already had tremendous success there," Latimer says of Project Cape. "We think our technology has a really bright future."

While Latimer looks ahead to the rapid growth of Fervo Energy, he says it's all due to the foundation he put in place for the company, which has a culture built on the motto, "Build things that last."

“You’re not going to get somewhere that really changes the world by cutting corners and taking short steps. And, if you want to move the needle on something as complicated as the global energy system that has been built up over hundreds of years with trillions of dollars of capital invested in it – you’re not going to do it overnight," he says on the show. "We’re all in this for the long haul together."

Houston initiative selected for DOE program developing hubs for clean energy innovation

community focus

Houston has been selected as one of the hubs backed by a new program from the United States Department of Energy that's developing communities for clean energy innovation.

The DOE's Office of Technology Transitions announced the the first phase of winners of the Energy Program for Innovation Clusters, or EPIC, Round 3. The local initiative is one of 23 incubators and accelerators that was awarded $150,000 to support programming for energy startups and entrepreneurs.

The Houston-based participant is called "Texas Innovates: Carbon and Hydrogen Innovation and Learning Incubator," or CHILI, and it's a program meant to feed startups into the DOE recognized HyVelocity program and other regional decarbonization efforts.

EPIC was launched to drive innovation at a local level and to inspire commercial success of energy startups. It's the third year of the competition that wraps up with a winning participant negotiating a three-year cooperative agreement with OTT worth up to $1 million.

“Incubators and Accelerators are uniquely positioned to provide startups things they can't get anywhere else -- mentorship, technology validation, and other critical business development support," DOE Chief Commercialization Officer and Director of OTT Vanessa Z. Chan says in a news release. “The EPIC program allows us to provide consistent funding to organizations who are developing robust programming, resources, and support for innovative energy startups and entrepreneurs.”

CHILI, the only participant in Texas, now moves on to the second phase of the competition, where they will design a project continuation plan and programming for the next seven months to be submitted in September.

Phase 2 also includes two national pitch competitions with a total of $165,000 in cash prizes up for grabs for startups. The first EPIC pitch event for 2024 will be in June at the 2024 Small Business Forum & Expo in Minneapolis, Minnesota.

Last fall, the DOE selected the Gulf Coast's project, HyVelocity Hydrogen Hub, as one of the seven regions to receive a part of the $7 billion in Bipartisan Infrastructure Law. The hub was announced to receive up to $1.2 billion — the most any hub will get.

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.

"Revterra is thrilled to be a founding member of the EnergyTech Nexus community," Ben Jawdat, founder and CEO of kinetic battery technology company Revterra, added. "Building a strong network of collaborators, customers, and investors is critical for any startup — particularly when you're building novel hardware. The Energytech Nexus community has been incredible at bringing all of the right stakeholders together."

Other partners, many of which have a strong presence in Houston, include:

BBVA
EarthX
Endress+Hauser
Goodwin
Greenbackers Investment Capital
ISR Energy
Latham & Watkins LLP
Ormazabal
Repsol
STX Next
XGS Energy

Jason Ethier, co-founding partner of EnergyTech Nexus, said that partnerships with these companies will be "pivotal" in supporting the organization's community of founders and Houston's broader energy transition sector.

“The Energy and Climate industry deploys over $1.5 trillion in capital every year to meet our growing energy demands. Our global founding partners recognize that this energy must be delivered reliably, cost effectively, and sustainably, and have committed to ensuring that technology developed without our ecosystem can find a path to market through testing and piloting in real-world conditions," Ethier said. "The ecosystem they support here solidifies Houston as the global nexus for the energy transition.”

EnergyTech Nexus also recently announced a "strategic ecosystem partnership" with Greentown Labs, aimed at accelerating growth for clean energy startups. Read more here.
