Houston solar company expands in Puerto Rico, receives DOE funding

island opportunities

A Houston renewable energy company has announced two initiatives that are hoping to provide more grid stability on the island of Puerto Rico.

Sunnova announced that it's expanding its Sunnova Sentient Virtual Power Plant platform. The company has also been selected by the United States Department of Energy’s Grid Deployment Office to be a part of a $440 million investment from the Puerto Rico Energy Resilience Fund.

Sunnova's VPP platform is expanding in Puerto Rico through a collaboration between the Sunnova Power Flex Program and LUMA's Customer Battery Energy Sharing program in Puerto Rico. This plan is "to transform the role of distributed solar and storage customers in enhancing grid stability during peak demand periods, all while offering them financial incentives for their participation," according to Sunnova's release.

Puerto Rican residents can opt into the Sunnova Flex Power Program and will be compensated for the power supplied by their batteries. According to Sunnova, a battery could earn up to $1,000 for this first pilot year.

“We are incredibly excited about the possibilities that our industry-leading VPP platform—delivered to our customers through our Sunnova Flex Power Program—holds for the people of Puerto Rico,” John Berger, CEO of Sunnova, says in the release. “As we continue to spearhead the transition towards a cleaner and more robust future, extending our VPP platform will not only help reshape the energy landscape in Puerto Rico but also empower our valued customers to play an integral role in bolstering grid stability. We eagerly anticipate the transformative impact this program will have on our customers and the Puerto Rican community at large.”

Sunnova has 52,000 solar and storage customers on the island and has installed storage to a capacity of 800 MWh.

“We're excited to collaborate with Sunnova on this important initiative, which signifies a major step in our ongoing efforts to enhance energy reliability for Puerto Rico. We're dedicated to achieving a more stable energy supply, reducing disruptions, and securing a resilient energy future, ultimately benefiting the people of Puerto Rico,” Jessica Laird, VP of Customer Experience at LUMA, says in the statement.

Sunnova's selection by the DOE Grid Deployment Office makes the company one of the eight to receive chunk of a $440 million commitment to install rooftop solar and batteries in PR.

Houston expert on importance of messaging when scaling an energy transition company

comms 101

Several years ago, Kelsey Hultberg decided to make a pivot. Looking for a role with career growth opportunities, the communications professional thought she'd find something at an oil and gas company, but then she met John Berger, founder and CEO of Sunnova, who was looking for someone to stand up their communications team amidst the solar energy company's growth.

"He hooked me," Hultberg shares on the Houston Innovators Podcast. "He said, 'I've got big plans for this company. I see where this energy industry is going, I see that we're prime for a transition, and I want to take this company public.' And I started a few weeks later."

Hultberg has been telling the story for Sunnova — which equips customers with solar and storage technology, providing them with energy independence — ever since, through scaling, new technologies, and its IPO in 2019.

Each phase of the company represented different challenges for Hultberg and her communications team. As she explains on the podcast, consistently conveying a strong message is key in any industry, but especially energy.

"Communication is critical," Hultberg says, "having a strategy and really being able to articulate who you are, what you stand for, what is your mission, what is your vision — and really beyond that, what is your strategy for how you move forward. ... You can never say the same thing to the same people too many times, especially when you're a company that some people have never heard of before."

And while there's a unique challenge to communications for energy transition companies, Hultberg says she views it as a huge opportunity as long as you have the right structure in place.

"Of course communications and being as strategic as possible with the story that you're telling and the narrative that you're weaving for your different audiences, but then you layer on an industry that's rapidly changing and is tumultuous at times," she says. "Being able to come back to the core mission and values is really incredible."

Hultberg says that when she originally joined the team in 2017, she thought a solar energy company in Houston was an interesting choice — and it was. Texas was not one of Sunnova's biggest markets at the time, Hultberg explains, but things are different now.

"Over the last couple of years, especially after Winter Storm Uri, where you saw a lot of people go without power. ... We had a lot of customers say, 'That can't happen again,'" she says. "You're seeing the adoption and uptick in solar in storage because they are looking for grid reliability and affordability and they aren't getting it from their utility providers."

MIT Technology Review released its list of 15 Climate Tech Companies to Watch this year, and Fervo Energy, a Houston-based, rapidly scaling geothermal energy company made the cut.

"Fervo’s enhanced geothermal approach promises to significantly expand the areas where we could tap into the carbon-free and nearly limitless source of energy beneath our feet. Geothermal offers the added advantage of generating electricity around the clock and calendar, making it an ideal clean source to fill in the gaps as grids increasingly come to rely on fluctuating renewables like solar and wind," reads the writeup on the company.

"It could provide a much cheaper or less controversial way of fixing that fundamental challenge in cleaning up the grid than building giant battery plants or adding nuclear power reactors, respectively," the MIT Technology Review continues.

Fervo, which announced earlier this year that its commercial pilot project has resulted in continuous carbon-free geothermal energy production, has raised $187 million since it was founded in 2017.

The article points to not only the accomplishments of the startup, but also the challenges it faces, including further proving out its technology's "effectively, affordably, and consistently on larger scales."

UH lands $8M in federal funding for fusion energy research

fusion funding

The University of Houston will receive $8 million in federal funding from the U.S. Department of Energy for its work on fusion technology to help power data centers and medical work.

Venkat Selvamanickam, professor at UH’s Cullen College of Mechanical and Aerospace Engineering and director of the Advanced Manufacturing Institute, has been tasked to lead the research on superconducting magnets that he said will make compact fusion reactors possible.

“Beyond fusion, superconductors can transform how we deliver power to data centers, enable highly efficient motors and generators and improve electric power devices,” Selvamanickam said in a news release. “They also enable critical applications such as MRI and proton beam therapy for cancer treatment. I want society to experience the broad benefits this remarkable technology can provide.”

UH is one of 23 institutions selected to share part of $134 million from the DOE’s Fusion Energy Sciences division. The total funding is split across two initiatives: $128 million for the Fusion Innovation Research Engine (FIRE) and $6.1 million for the Innovation Network for Fusion Energy program, according to the university.

UH will partner with the FIRE Collaborative for the research, which looks to understand why superconducting magnets in fusion reactors break down and work on developing solutions to make them more resilient.

“The advantage of fusion is it’s clean and it does not require storage. Solar energy can’t be used at night, and wind energy depends on wind conditions,” Selvamanickam added in the release. “Our goal is to make fusion a truly viable energy source.”

Energy expert on Houston's advantage: Building affordability and reliability for all

Guest Column

As the energy capital of the world, Houston has been at the forefront of innovation, powering industries and communities for generations. Many Houston families, however, are facing a reality that undermines our leadership: high energy bills and ongoing concerns about grid reliability.

Affordability and reliability are not just technical issues; they’re equity issues. To remain the world leader in energy, we must ensure that every household has access to affordable and dependable power.

Affordability: The First Step Toward Equity

According to the recent 2025 study by The Texas Energy Poverty Research Institute, nearly 80% of low- to moderate-income Houstonians scaled back on basic needs to cover electric bills. Rising costs mean some Houstonians are forced to choose between paying their utility bill or paying for groceries.

Additionally, Houston now has the highest poverty rate among America’s most populous cities. Energy should not be a privilege for only half of our city’s population. That’s why affordability needs to be at the center of Houston’s energy conversation.

Several practical solutions exist to help address this inequity:

  • We can increase transparency in electricity pricing and help families better understand their electricity facts labels to make smarter choices.
  • We can expand energy efficiency programs, like weatherizing homes and apartments, swapping out old light bulbs for LEDs, and adopting smart thermostats.
  • Incentives to help families invest in these changes can deliver long-term benefits for both them and apartment complex owners.

Many small changes, when combined, can add up to significant savings for families while reducing overall demand on the grid.

Reliability: A Shared Community Priority

The memories of Hurricane Beryl, Derecho, and Winter Storm Uri are still fresh in the minds of Texans. We saw firsthand the fragility of our grid and how devastating outages are to families, especially those without resources to handle extreme weather. Reliability of the grid is an issue of public health, economic stability, and community safety.

Houston has an opportunity to lead by embracing innovation. Grid modernization, from deploying microgrids to expanding battery storage, can provide stability when the system is under stress. Partnerships between utilities, businesses, and community organizations are key to building resilience. With Houston’s innovation ecosystem, we can pilot solutions here that other regions will look to replicate.

Energy Equity in Action

Reliable, affordable energy strengthens equity in tangible ways. When households spend less on utilities, they have more to invest in their children’s education or save for the future. When power is stable, schools remain open, businesses continue to operate, and communities thrive. Extending energy efficiency programs across all neighborhoods creates a fairer, more balanced system, breaking down inequities tied to income and geography.

Studies show that expanding urban green spaces such as community gardens and tree-planting programs can lower neighborhood temperatures, reduce energy use for cooling, and improve air quality in disadvantaged areas, directly reducing household utility burdens.

In Houston, for example, the median energy burden for low-income households is 7.1% of income, more than twice that of the general population, with over 20% of households having energy burdens above 6%.

Research also demonstrates that community solar programs and urban cooling investments deliver clean, affordable power, helping to mitigate heat stress and making them high-impact strategies for energy equity and climate resilience in vulnerable neighborhoods.

Public-Private Partnerships Make the Difference

The solutions to affordability and reliability challenges must come from cross-sector collaboration. For example, CenterPoint Energy offers incentives through its Residential and Hard-to-Reach Programs, which support contractors and community agencies in delivering energy efficiency upgrades, including weatherization, to low-income households in the greater Houston area.

Nonprofits like the Houston Advanced Research Center (HARC) received a $1.9 million Department of Energy grant to lead a weatherization program tailored for underserved communities in Harris County, helping to lower bills and improve housing safety

Meanwhile, the City of Houston’s Green Office Challenge and Better Buildings Initiative bring private-sector sponsors, nonprofits, and city leadership together to drive energy reductions across millions of square feet of commercial buildings, backed by training and financial incentives. Together, these partnerships can result in real impact that brings more equity and access to affordable energy.

BKV Energy is committed to being part of the solution by promoting practical, consumer-focused strategies that help families save money and use energy more efficiently. We offer a suite of programs designed to provide customers with financial benefits and alleviate the burden of rising electricity bills. Programs like BKV Energy’s demonstrate how utilities can ease financial strain for families while building stronger customer loyalty and trust. Expanding similar initiatives across Houston would not only lower household energy burdens but also set a new standard for how energy companies can invest directly in their communities.

By proactively addressing affordability, energy companies can help ensure that rising costs don’t disproportionately impact vulnerable households. These efforts also contribute to a more resilient and equitable energy future for Houston, where all residents can access reliable power without sacrificing financial stability.

Houston as a Blueprint

Houston has always been a city of leadership and innovation, whether pioneering the space race, driving advancements in medical research at the Texas Medical Center, or anchoring the global energy industry. Today, our challenge is just as urgent: affordability and reliability must become the cornerstones of our energy future. Houston has the expertise and the collaborative spirit to show how it can be done.

By scaling innovative solutions, Houston can make energy more equitable, strengthening our own community while setting a blueprint for the nation. As the energy capital of the world, it is both our responsibility and our opportunity to lead the way to a more equitable future for all.

Energy startup Base Power raises $1 billion series C round

fresh funding

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.”
