Houston-based Sunnova Energy International, a provider of commercial and residential solar energy services, has teamed up with fintech platform Tenet Energy to help Americans buy electric vehicles and solar power systems.

The two companies will offer special discounts and financing plans to encourage Sunnova customers to switch to electric vehicles purchased through Tenet and Tenet customers to adopt Sunnova’s solar energy systems.

“Our suite of energy solutions — which includes EV chargers — addresses the concerns of higher electricity costs associated with fueling EVs while enabling buyers the convenience of charging from home as they electrify their transportation,” Michael Grasso, executive vice president and chief revenue officer at Sunnova, says in a news release.

The goal of the partnership is to enable homeowners to charge electric vehicles with solar power, which the companies say would lower utility and fuel costs.

“Our mission is to help Americans electrify their lives, starting with their vehicle,” says Alex Liegl, CEO of New York City-based Tenet. “EVs are an excellent way to begin your sustainability journey and save money, but they are also part of a broader energy system that works synergistically with other clean energy home assets like solar.”

Houston firm's portfolio co. goes online with solar, energy storage facility in Nevada

powering on

A portfolio company of Quinbrook Infrastructure Partners, an energy-focused investment manager with U.S. offices in Houston and New York, has flipped the switch on its solar power and battery energy storage system in Nevada’s Mojave Desert.

The portfolio company, Oakland, California-based Primergy Solar, says its Gemini Solar + Storage project near Las Vegas is now fully operational.

Gemini’s 1.8 million solar panels can generate up to 690 megawatts of power, enough to meet 10 percent of Nevada’s peak power demand. The panels are paired with 380 megawatts of four-hour battery storage.

“Gemini creates a blueprint for holistic and innovative clean energy development at mega scale, and we are proud to have brought this milestone project to life and to have delivered so many positive impacts across job creation, environmental stewardship, and local community engagement,” David Scaysbrook, co-founder and managing partner of Quinbrook, says in a news release.

Primergy says Gemini is the biggest solar-and-storage duo in the U.S.

“Achieving full commercial operations marks a significant technical and financial milestone for our team. We successfully navigated challenging supply chain and inflation issues through proactive planning and collaboration to bring this project online,” Primergy CEO Ty Daul says.

Primergy develops, owns, and operates utility-scale solar power and battery storage projects across the U.S. It manages projects in several U.S. energy markets, including the one served by the Electric Reliability Council of Texas (ERCOT).

As Gemini was taking shape, Primergy and Quinbrook closed on $1.9 billion in debt and tax equity financing for construction and development.

In October 2022, APG, the largest pension asset manager in the Netherlands, acquired a 49 percent ownership stake in Gemini on behalf of pension fund client ABP.

In April 2024, the remaining 51 percent share of the project was acquired by the $600 million Quinbrook Valley of Fire Fund. Funds associated with Blackstone Strategic Partners and Ares Management Infrastructure Secondaries were the lead investors.

Houston company secures $837M for trio of Texas energy storage projects

power move

Houston-based clean energy company Intersect Power has wrapped up $837 million in financing for the construction and operation of three standalone battery energy storage systems in Texas.

The money came in the form of debt financing, construction debt, and tax equity. The projects qualify for tax credits under the federal Inflation Reduction Act. Backers of the financing include Deutsche Bank, Morgan Stanley, and affiliates of HPS Investment Partners.

All three storage systems — Lumina I, Lumina II, and Radian — are expected to be online this year. Each system will be capable of storing 320 megawatts of solar power with a two-hour duration.

“Batteries will be a vital part of the energy transition and are the perfect complement to the billions of dollars of solar generation that we are building in California and Texas,” Sheldon Kimber, founder and CEO of Intersect, says in a news release.

Kimber says the storage systems will help Intersect Power triple the size of its portfolio over the next three years.

Intersect’s portfolio features 2.2 gigawatts of solar projects that are already operating, and 2.4 gigawatt hours of storage being operated or built. The company was founded in 2016.

Intersect recently signed a deal with Tesla Energy for 15.2 gigawatt hours of Megapack battery energy storage systems. The contract, which will deliver systems for Intersect projects in Texas and California, ends in 2030.

Houston entrepreneur launches new venture to shine light on sustainability

texas innovator

A Houston nuclear engineer and entrepreneur wants consumers to capture their own ray of sunlight to brighten the prospect of making clean energy a bigger part of the power grid.

Solar Slice Founder Nathan Childress says his new venture offers a fulfilling way to encourage and promote solar energy and a greener planet. An experienced entrepreneur, Childress also serves as founder and CEO of technology software company Macorva.

Although trained in nuclear power plant design, solar power drew his interest as a cheaper and more accessible alternative, and Childress tells InnovationMap that he thinks that the transition to cleaner energy, in Texas especially, needs to step up.

With energy demand skyrocketing, and the push toward renewable solutions, solar seems like a safe bet for Childress, a former competitive high-stakes poker player. Childress cites a recent Yale University study that says 63 percent of Americans “feel a personal responsibility to help reduce global warming.”

But some studies show that 80 to 90 percent of the money invested into fighting climate change “aren’t going to things that people actually consider helpful,” he says.

“They’re more just projects that sound good, that are not actually taking any action,” says Childress, who has called Houston home for 25 years. He received his doctorate in medical physics at M.D. Anderson Cancer Center, where he worked on software that provided radiation therapy for patients.

The initial Kickstarter fundraising round, which will be launched soon, will finance the construction of one utility-scale solar farm, on about five to 10 acres, which would produce about 1 megawatt, or 1,000 kilowatts, of clean energy. The plant would make enough energy to power about 200 average homes.

Childress says interest has been strong, with several thousand signed up on the Kickstarter launch list. Some who are signed up expressed interest in a subscription, he said, and that may be offered later. Initially, though, for a one-time purchase of $95, a Solar Slice client can purchase one virtual 50W slice of solar power, produced by the farm. Over its lifetime, Childress says, that one purchase can offset three tons of carbon dioxide.

The app tracks carbon offsetting, and energy production for the slice, showing a client “exactly how much I have helped the climate, here’s exactly how (many) emissions I have prevented from putting in the atmosphere,” he says.

The energy produced by five slices can offset the average American’s carbon footprint for a year, and the power generated by the solar farm will be sold to the electric grid. As clients purchase more slices, they can earn eco-credits to donate to other climate-friendly partners, to plant trees or create pollinator habitats.

While Solar Slice is a for-profit venture, contributors won’t get rich or even make money from their purchase. Rather, it provides validation.

“Our focus is maximizing the real world impact, not for financial gain. This is not something people sign up (for) to make money. We’re really clear about that,” Childress says. “I want to show that it’s possible to have a for-profit company that is sustainable, that does good work.

“And hopefully, we can be part of the spirit…for a bigger movement, and for consumers and business, especially, to do things that matter.”

The largest U.S. solar plants are in Nevada and California, and those states are sites under consideration, but Childress says Texas is the most likely home for the initial project. The ten largest utility-scale solar plants in Texas by capacity are all in far west or central parts of the state, according to the state comptroller’s office.

Childress has a team of four, who are handling the marketing, plant design and site scouting, and hopes to hire five to 10 more, depending on response and growth. He says the Solar Slice consumer can directly connect in real time to the contribution that their purchase will make toward a green energy future.

“That was our inspiration..let’s start something that is really making a difference..and making really clear to the individuals what’s being done,” he says.

Solar energy has become a growing source of power for Texas, comprising about 6 percent of the state’s energy generation, as of 2022, the comptroller’s office says.

The state ranks first in projected growth of solar energy over the next five years, with more than 9,500 operating solar plants, and many thousands more announced, according to the state Public Utility Commission.

“We would absolutely love to make this into something where we are building plants around the nation, around the world,” Childress he says.

However, resistance to alternative energy projects like solar and wind, especially on a large scale, remains in some quarters.

Obtaining site permits for swaths of land can be also a challenge. For example, a recent survey by Berkeley Lab of 123 professionals from 62 unique, large-scale wind and solar energy facilities showed that about one-third of wind and solar siting applications in the past five years were canceled.

Half of the projects experienced delays of six months or longer. And according to the survey, developers expect the trend to continue, and become more expensive to address.

However, another Berkeley Lab survey of residents who live within three miles of a solar power plant showed that most view the plant positively. The larger the plant, the more negative the response in the survey. The smaller the farm, the more positive the reactions.

Childress says many of the common objections to utility-scale solar farms are misguided, and incorrect. For example, the concern that they would take over available farmland or take up too much space.

He says that even if the entire U.S. power grid relied solely on solar power, the plants would occupy not even a half percent of available land, which is about one percent farmland.

Houston company nears completion of innovative solar-powered street lights project

light the way

Houston-based EnGoPlanet is nearing completion of what it touts as the largest installation of solar-powered street lights in the U.S.

The project, which relies on EnGoPlanet’s ENGO Utility program, is in Calhoun County. It features 300 solar-powered, motion-activated street lights and 20 camera-equipped power poles at several Calhoun County parks. Port Lavaca, close to 130 miles southwest of Houston, is the county seat of Calhoun County.

Calhoun County Commissioner David Hall calls the project “a game-changer for innovation in the sustainable energy space.”

The solar-powered street lights were made according to DarkSky guidelines designed to reduce nighttime light pollution.

The lighting project is part of a 15-year initiative aimed at boosting Calhoun County’s commitment to solar and other forms of renewable energy.

“Our work in Calhoun County is a prime example of how collaboration and innovative thinking can create not just economic value, but also profound social and environmental impact. Municipalities and counties should explore many available grants through the Inflation Reduction Act to help fund renewable energy initiatives for their communities,” Petar Mirovic, CEO of EnGoPlanet, says in a news release.

Calhoun County is just one of several places where EnGoPlanet, founded in 2019, has installed solar-powered street lights. Others include Houston, Dallas, Montenegro, Qatar, and Serbia.

Houston nonprofit flips switch on solar panel project thanks to sustainability grant

shine on

A Houston-area farm is one step closer to operating completely off-grid thanks to new solar panels installed with funding provided by a grant.

In a step towards a greener future, Hope Farms, a 7-acre farm operated by a Houston nonprofit organization, Recipe for Success Foundation, unveiled 18 new solar panels on Tuesday. This significant move is part of a collective effort to completely transition the farm to solar power, demonstrating its commitment to sustainability.

“The industry (solar power) itself is intimidating to people,” Gracie Cavner, founder and CEO of Hope Farms and Recipe for Success, tells EnergyCapital. “Part of our work is to inspire people to replicate what we're doing. We want to show that things aren't as hard as you think they are.”

The nonprofit organization is recognized in Houston for its work in addressing childhood obesity, with a long held mission of demystifying the common misconceptions around healthy eating. It is now tackling another challenge: dispelling the myth that solar power implementation is difficult. Hope Farms' latest initiative will not only further its energy independence, it will also show that adopting renewable energy, similar to embracing healthy food choices, is a feasible option.

The 18 solar panels will power the farm's composting toilet facility and all of the electricity used in its barn, which acts as its market stand and kitchen. Its next green phase is fast approaching and will implement solar panels on top of its flower studio, where the farm's internet and security systems reside. Its final phase will install a water well pump.

“We really did a lot of direct learning,” Cavner said. “We worked directly with solar engineers, not somebody with a company that benefited from us making one decision or another. I feel like more people would have solar if they realized they could do that.”

This is not the first green step Hope Farms has taken thanks to a Green Mountain Energy Sun Club grant, and certainly not the last. Last year, the farm cut the ribbons to its rainwater capture system that now saves roughly 95,000 gallons of water per year by capitalizing on the city’s abundant rainfall.

Since the farms beginning in 2016, it has relied on solar, even when it was only fields lit by a few lights. Soon, Hope Farms will be completely off-grid, running its entire operation on sustainable resources.

“With this expansion, I feel like it’s going to be taking the rock out of the middle of the river,” Cavner said. “It’s going to open up this train and make it easier for anybody to jump in and do it. The first step is kicking the door open and making more people want to pursue it.”

Geothermal exec on Houston expansion, commercialization and more

Q&A

Challenges in the energy transition often center around two questions: Where will organizations find the resources? And how will projects be financed?

XGS Energy's next-gen closed-loop geothermal well architecture addresses both issues head-on. The California-based company saw massive growth in the Houston market last year and recently completed a 100-meter field demonstration in central Texas, marking a major milestone for its technology's commercialization and potential for scale.

In an interview with EnergyCapital, Axel-Pierre Bois, XGS's Chief Technology Officer, shares what drew him to the geothermal space, why XGS is expanding in Houston and what the company's plans are for the year ahead.

How does XGS Energy's technology address the biggest challenges in geothermal energy?

XGS Energy is developing a geothermal system that decouples geothermal energy from its traditional dependence on water and geology to deliver affordable, clean energy anywhere there is hot rock.

Historically, geothermal resources have been hard to locate, as conventional systems require the overlap of hot rock, porous and permeable geology, and abundant water to produce energy, limiting their potential to a few select hot spots worldwide. Instead of relying on an underground fracture network that drives the geology and water requirements, the base component of XGS’s system is a single well, in which fluid is pumped to a hot rock resource and then returned to the surface through a tube-in-shell design, creating a sealed, closed loop. This allows XGS to produce geothermal energy anywhere where there is hot rock, unlocking terawatt-scale potential in the U.S. alone.

Geothermal systems have also struggled to secure project financing, as many systems have historically faced high levels of unplanned cost risk due to factors including water loss and production uncertainty. XGS’s sealed, closed-loop system ensures that it can provide reliable, predictable electricity throughout its lifespan. XGS also boosts the cost-competitiveness of its system through our major innovation, a proprietary thermally conductive materials system that is installed downhole around each well, increasing the heat transferred to the closed-loop system by 30-50%.

What has drawn you to a career in the geothermal energy space?

I have been in the subsurface industry for over 30 years, developing technical solutions for companies in the fields of geosciences, underground storage, upstream oil and gas, and geothermal heat harvesting to help improve their overall economic, ethical and environmental footprints. In 2009, I founded Curistec, a technology company providing research, engineering and technical services for geomechanics, wellbore integrity, well abandonment, cement design and cement and rock testing. A few years back, Curistec assisted with the Iceland Deep Drilling Project, helping to develop cement formulations for superhot geothermal well applications to enable drilling in high-temperature environments. As I looked toward the future, it became clear that next-generation geothermal technologies would transform the geothermal energy industry and open new markets worldwide. Curistec had been working closely with the XGS Energy team as technology partners for several years, so joining the team directly to help shape the technology development was an exciting opportunity to help develop and deploy a new system to unlock the full terawatt-scale potential of geothermal energy.

Tell us about the 100-meter field demonstration in central Texas completed in 2024 — what all did you and your team learn from the test?

Our 100-meter field demonstration in central Texas marked a significant step in our progress toward deploying geothermal energy in a commercial setting. With this field operation, we successfully demonstrated our ability to mix, pump and place our thermally conductive materials system at a commercial scale, using off-shelf tools and technologies. This was a significant milestone, taking us from theoretical models and laboratory tests to field-scale operations, proving that our novel geothermal system is operationally viable in real-world well conditions.

The completion of the Texas field demonstration advanced XGS into the new wave of geothermal innovators that are putting real steel in the ground. In 2024, we kicked off construction at our commercial-scale demonstration in California and are excited to share updates in the year ahead.

Last year, XGS Energy leased over 10,000 square feet of office space in Memorial City. How has Houston's business community and opportunities benefitted the company?

Houston, the epicenter of the oil and gas industry, has become a hub of energy innovation, offering attractive incentives for growing companies like XGS. The region’s workforce, which is home to some of the best subsurface engineers and operational talent in the energy sector, was a key factor for XGS when we were planning our operational roadmap. This expertise, paired with proximity to our partners in the field services industries, like cementing and drilling, is both apracticaland tactical advantage for XGS.

We’ve built a strong technical and operational team here at XGS, with experience from the oil and gas industry, utilities and power project developers. XGS is planning for continued growth in the Houston area, leveraging the region’s leading engineering and operational workforce and its intensifying interest in supporting the energy transition.

What are XGS Energy's goals for 2025?

In 2024, the XGS Energy team made significant progress toward our goal of providing clean, round-the-clock energy with our solid-state geothermal system. In 2025, XGS Energy will be focused on deploying its geothermal system at a commercial scale, starting with the completion of our full-scale prototype in California. XGS will also continue accelerating our commercial traction, expanding our already robust and highly differentiated geothermal resource evaluation toolkit, advancing our global project pipeline, and growing our team to strengthen our operational capability and capacity.

Environmentalists say Trump's energy order would subvert Endangered Species Act

In The News

Environmental groups concerned about loss of protections for vanishing animals see one of President Donald Trump’s early executive orders as a method of subverting the Endangered Species Act in the name of fossil fuel extraction and corporate interests.

Trump declared an energy emergency via executive order earlier this week amid a promise to “drill, baby, drill.” One section of the order states that the long-standing Endangered Species Act can’t be allowed to serve as an obstacle to energy development.

That language is a pathway to rolling back protections for everything from tiny birds like the golden-cheeked warbler to enormous marine mammals like the North Atlantic right whale, conservation groups said Wednesday. Some vowed to fight the order in court.

The Endangered Species Act has been a hurdle for the development of fossil fuels in the U.S. for decades, and weakening the act would accelerate the decline and potential extinction of numerous endangered species, including whales and sea turtles, said Gib Brogan, a campaign director with conservation group Oceana.

“This executive order, in a lot of ways, is a gift to the oil and gas industry and is being sold as a way to respond to the emergency declaration by President Trump,” Brogan said. “There is no emergency. The species continue to suffer. And this executive order will only accelerate the decline of endangered species in the United States.”

The Endangered Species Act has existed for more than 50 years and is widely credited by scientists and environmentalists with helping save iconic American species such as the bald eagle from extinction. A key section of the act directs federal agencies to work to conserve endangered and threatened species and use their authorities to protect them.

Trump's order declaring a national energy emergency took direct aim at the authority provided by the Endangered Species Act. It orders federal departments to treat energy production as an emergency, which could help expedite approval of energy projects that might otherwise be held up.

The order also convenes a committee to “identify obstacles to domestic energy infrastructure specifically deriving from implementation of the ESA or the Marine Mammal Protection Act,” another landmark conservation law. It states the committee could consider regulatory reforms, including “species listings,” as part of its work.

The Trump administration did not respond to a request for comment on the executive order. The order defines energy mostly as fossil fuels such as crude oil and and coal and does not include renewable energies such as wind power. It also states that energy production is an emergency because “an affordable and reliable domestic supply of energy is a fundamental requirement for the national and economic security of any nation.”

While environmentalists herald the Endangered Species Act as a landmark law, pro-development and free market interests have long criticized it for holding up the building of energy, infrastructure, housing and other projects. Some, including the influential Heartland Institute, applauded Trump's declaration of an energy emergency this week.

Conservatives have also decried the Endangered Species Act as inefficient. It took the U.S. Fish and Wildlife Service years to follow the process of potentially delisting the golden-cheeked warbler, a small songbird that breeds only in the forests of central Texas, said Connor Mighell, an attorney with Texas Public Policy Foundation, a free market research institute.

Trump's executive order could help stop the Endangered Species Act from resulting in drawn-out permitting processes and lengthy litigation, said Brent Bennett, energy policy director for Texas Public Policy Foundation.

“We're hoping that can improve some of the permitting processes and remove some of these barriers,” Bennett said.

But the act is critical to maintaining species threatened with extinction, environmentalists said. They cite whales such as the North Atlantic right whale, which numbers less than 400 and is vulnerable to collisions with ships and entanglement in fishing gear, as an example of an animal that must be protected under the act. The Rice's whale, which numbers even fewer and is vulnerable to disruption from oil drilling in the Gulf of Mexico, is another prime example, environmentalists said.

The nation's symbol, the bald eagle, is a perfect example of the importance and effectiveness of the Endangered Species Act, said Andrew Bowman, president of the conservation group Defenders of Wildlife.

“President Trump’s election to office did not come with a mandate to deny Americans a clean and healthy environment or destroy decades of conservation successes that have ensured the survival and recovery of some of America’s most iconic species, including the bald eagle, which was newly named our country’s national bird and is only with us today thanks to the Endangered Species Act," Bowman said.

Texas ranks as No. 2 manufacturing hub in U.S., behind only California

by the numbers

Texas ranks among the country’s biggest hubs for manufacturing, according to a new study.

The study, conducted by Chinese manufacturing components supplier YIJIN Hardware, puts Texas at No. 2 among the states when it comes to manufacturing-hub status. California holds the top spot.

YIJIN crunched data from the U.S. Census Bureau, International Trade Administration, and National Association of Manufacturers to analyze manufacturing activity in each state. The study weighed factors such as number of manufacturing establishments, number of manufacturing employees, total value of manufacturing output, total manufacturing exports and manufacturing’s share of a state’s gross domestic product.

Here are Texas’ figures for those categories:

19,526 manufacturing establishments
847,470 manufacturing employees
Total manufacturing output of $292.6 billion
Total manufacturing exports of $291.9 billion
11.3 percent share of state GDP

According to Texas Economic Development & Tourism, the state’s largest manufacturing sectors include automotive, tech, petroleum, chemicals, and food and beverage.

“The Lone Star State is truly a manufacturing powerhouse,” the state agency says.

In an October speech, Texas Gov. Greg Abbott praised the state’s robust manufacturing industry.

“We are proud that Texas is home to a booming manufacturing sector,” he said. “Thanks to our strong manufacturing sector, ‘Made in Texas’ has never been a bigger brand.”

Houston is a cornerstone of Texas’ manufacturing industry. The region produces more than $75 billion worth of goods each year, according to the Greater Houston Partnership. That makes Houston the second-ranked U.S. metro area for manufacturing GDP. The more than 7,000 manufacturing establishments in the area employ over 223,000 people.

“As one of the most important industrial bases in the world, Houston has access to many global markets thanks to its central location within the U.S. and the Americas,” the partnership says.
