The end of the solar tax credit is not the end of the solar industry. Photo by Kindel Media/Pexels

Texas still has its best solar days ahead of it, even as federal tax credit sunsets

Guest Column

If you follow energy policy, you already know that Congress repealed the 30% residential solar tax credit. This poses a significant challenge for continued growth in the market. It also provides an opportunity for the industry to grow in a smart, consumer-friendly way. That’s why in Texas, the story is what happens next: The state and the market are continuing to make going solar much simpler, better, and cheaper.

Policies are moving in the right direction. For example, starting this month, a bipartisan permitting reform takes effect that will cut red tape for home solar and batteries. It lets licensed third-party professionals review plans and perform inspections, requires agencies to post standardized rules and fees online, and allows homeowners to start work once those third-party approvals are submitted. It also shifts negligence liability to the third-party reviewer, thereby reducing municipal risk while accelerating safe, code-compliant installs. In plain English: fewer bottlenecks, faster installs, and lower “soft costs.”

As a result, Houston is already piloting the National Renewable Energy Lab’s free SolarAPP+ to auto-approve standard solar designs, which cuts roughly 12 days from typical timelines. Independent analyses estimate that these automated permitting rules could trim rooftop solar costs by thousands. In other words, even small, costless policy changes like this can save you almost as much money as the huge solar tax credit did, and these great reforms are happening all the time, and they make the process much more convenient and reliable.

While Texas is making solar simpler, it’s also helping consumers have a good experience when going solar. As of this month, Texas law now also requires solar salespeople to register with the Texas Department of Licensing and Regulation. The same bill standardizes contracts and provides for mandatory disclosures of upfront cost and financing terms. The whole solar industry benefits when customers have a good solar experience. Word of mouth is vital to keeping solar shining.

There's yet another pro-solar Texas law that's also going into effect this month: in addition to SB 1202 (streamlining solar permits) and SB 1036 (regulating solar sales tactics), the legislature is also supporting the dissemination of information about your options when going solar via SB 1697. You can read more about these three brand-new pro-solar state laws here.

The end of the solar tax credit is not the end of the solar industry. Far from it.

EPA scraps $7B solar program, stripping Texas of hundreds of millions in clean energy funds

funding cut

The U.S. Environmental Protection Agency is ending a $7 billion Biden-era program that was supposed to enable low-income Americans to access affordable solar power. The program, which EPA Administrator Lee Zeldin called a “boondoggle,” would have benefited more than 900,000 U.S. households.

In line with the EPA’s action, the Lone Star State is losing a $249.7 million grant awarded last year to the Harris County-led Texas Solar for All Coalition. The grant money would have equipped more than 46,000 low-income and disadvantaged communities and households in Texas with residential solar power. The nonprofit Solar United Neighbors organization said Texas had already begun to roll out this initiative.

Also slipping out of Texas’ hands are:

  • A more than $156 million 19-state grant awarded to the Clean Energy Fund of Texas in partnership with the Bullard Center for Environmental and Climate Justice at Houston’s Texas Southern University. The Clean Energy Fund is a Houston-based “green bank” that backs investments in solar and wind power.
  • Part of a $249.3 million multistate grant awarded to the Community Power Coalition’s Powering America Together Program. The nonprofit Inclusive Prosperity Capital organization leads the coalition.
  • Part of a $249.8 million multistate grant awarded to the Solar Access for Nationwide Affordable Housing Program, led by the nonprofit GRID Alternatives organization.

In a post on the X social media platform, Zeldin said the recently passed “One Big Beautiful Bill” killed the Greenhouse Gas Reduction Fund, which would have financed the $7 billion Solar for All program.

“The bottom line is this: EPA no longer has the statutory authority to administer the program or the appropriated funds to keep this boondoggle alive,” Zeldin said.

Anya Schoolman, executive director of Washington, D.C.-based Solar United Neighbors, accused the EPA of illegally terminating the Solar for All program. She said ending the program “harms families struggling with rising energy costs and will cost us good local jobs.”

U.S. Sen. Bernie Sanders, a Vermont independent, joined Schoolman in alleging the EPA’s “outrageous” action is illegal. Sanders introduced the legislation that established the Solar for All program.

The senator lashed out at President Trump for axing the program in order “to protect the obscene profits of his friends in the oil and gas industry.”

Houstonians, here's your sign to score solar panels at a discount. Photo by Kindel Media/Pexels

Houston rolls out discounts on solar installation to move the needle on lower-carbon options

expert panels

A city of Houston initiative is offering a discounted rate for solar panel installation for homeowners and small businesses.

This year's Solar Switch Houston deal produces an average savings of $5,315 for each Houstonian who registers with Solar Switch, according to a news release from the city, which partnered with the nonprofit Solar United Neighbors. It's the third time the organizations have teamed up to provide the discount.

“We had great success with the first two rounds of Solar Switch Houston where residents were provided with a trusted information source and a substantial group discount,” City of Houston Interim Chief Resilience and Sustainability Officer Nicholas Hadjigeorge says in the release. “I am confident that the savings attained in the third round of the program will play a crucial role for residents deciding if solar is the right choice."

The organization vetted solar installers, factoring in "product quality, warranties, company financial stability, and history of customer satisfaction," per the news release. These installers then participated in a reverse auction to provide the discounted services. Those interested in learning more can head to SolarSwitch.com/Houston.

"Everyone deserves to benefit from generating their own solar energy. That’s why we designed Solar Switch – to make installing solar affordable and straightforward for more Houstonians than ever before," America Garcia, Texas program director for Solar United Neighbors, says in the release. "I’m excited to see how much we can broaden the reach and benefits of solar group buying with the continuation of Solar Switch Houston."

Houston charges up new program to help locals buy and install affordable solar panels

sunny days

Alternative-energy-seeking locals now have a sunny way to buy into a solar. The City of Houston has launched Texas Solar SwitchHouston, a new program aimed at helping Houstonians purchase and install rooftop solar panels and battery storage.

In partnership with Solar United Neighbors, the Solar Switch program offers hassle-free way to purchase solar panels by creating a massive, group discount for residents, be it home or small business needs.

This comes with the new Inflation Reduction Act’s clean energy incentives and is part of the City of Houston's Climate Action Plan goal to generate 5 million MWh per year of local solar, per a press release. Customers who install solar also receive a 30-percent tax credit, thanks to the The Inflation Reduction Act.

Registration for the program is free and available online. The City of Houston assures that there is "no obligation for homeowners to purchase solar panels." Discounts and installers are determined through a competitive auction process, per the City.

"With energy prices increasing, homeowners and small businesses are looking for opportunities to save on their energy bills and increase their resilience to climate-related events," said Mayor Sylvester Turner. "Texas Solar Switch Houston provides our community with a simple and straightforward way to become better informed about solar energy and access a competitive offer from a vetted, experienced solar installation company."

Signed and passed into law by the Biden Administration in August, the Inflation Reduction Act will invest some $369 billion in domestic energy production and manufacturing with a goal of reducing carbon emissions by 40 percent by 2030. That federal mandate means locals can now take steps towards power backup, while potentially easing up on the beleaguered Texas grid.

“More and more Houstonians are looking to solar and battery storage for self-sufficiency, which has the added benefit of making our grid more resilient,” said Hanna Mitchell, Texas program director for Solar United Neighbors, in a statement. “With the recent passage of the IRA, now is a particularly good time to go solar.”

Houston AI startup rolls out platform to reshape oil and gas workflows

AI for energy

Houston-based Collide is looking to solve AI issues in the energy industry from within.

Co-founded by former oil roughneck Collin McLelland, the company has developed AI software for operators and field teams, shaped by firsthand oilfield experience. Its AI-native platform “retrieves and synthesizes data from authoritative sources to deliver accurate, cited, and energy-focused insights to oil and gas professionals,” according to the company.

“Oil and gas has a graveyard full of technology that was technically impressive and operationally useless,” McLelland tells Energy Capital. “The reason is almost always the same: the people who built it didn't understand what they were actually solving for. When you're an outsider, you see workflows and try to automate them. When you're an insider, you understand why those workflows exist—the regulatory constraints, the physical realities, the liability concerns, the trust dynamics between operators and service companies.”

Collide’s large language model, known as RIGGS, performed well in recent benchmarking results when taking a standardized petroleum engineering (SPE) exam, the company reports. The exam assesses understanding from conceptual terminology to complex mathematical problem-solving.

According to Collide, RIGGS achieved a score of 67.5 percent on a 40-question subset of the SPE petroleum engineering exam, outperforming other large language models like Grok 4 (62.5 percent), Claude Sonnet 4.5 (52.5 percent) and GPT 5.1 (4 percent).

RIGGS completed the test in 15 minutes, while Grok took two hours. Collide hopes over the next few months, RIGGS will receive a score between 75 percent to 80 percent accuracy.

The software could potentially help oil and gas companies produce accurate outputs and automate trivial workflows, which can open up valuable time for engineers and teams to work on other pressing matters, according to McLelland.

“Collide exists because we sat in those seats — we were the engineers, the operators, the field guys,” he says. ”RIGGS scoring higher on the PE exam versus the frontier labs isn't a party trick. It's evidence that the model understands petroleum engineering the way a petroleum engineer does, because it was built by people who do.”

RIGGS was trained on Collide’s Spindletop hardware and is supported by a vast library of information, as well as a reasoning engine and validation layer that uses logic to solve problems.

“Longer term, we see RIGGS as the intelligence layer that sits underneath every operator's workflow — not a chatbot you open in a browser, but something embedded in the tools engineers already use,” McLelland says. “The goal is to give every engineer the knowledge and pattern recognition of a 30-year veteran, on demand."

According to McLelland, Collide is already building toward reservoir analysis and production optimization, automated regulatory compliance (Railroad Commission filings, W-10s, G-10s), workover report generation, and engineering decision support in the field for near-term use cases. In March, Collide and Texas-based oil and gas operator Winn Resources announced a collaboration to automate the time-intensive process of filing monthly W-10 and G-10 forms with the Texas Railroad Commission, completing what’s normally a multi-hour task in under 30 minutes. Collide reports that Winn’s infrastructure now automates regulatory filings and provides real-time visibility into data gaps, which has reduced processing time by over 95 percent.

“Before Collide, I'd spend hours manually keying in filings,” Buck Crum, director of operations, said in a news release. “(In March), we had 50 wells to file and I was done in 20 minutes. It does the majority of the heavy lifting while keeping me in control. That human-in-the-loop approach saves meaningful time and gives us greater confidence in our compliance and reporting.”

Collide was originally launched by Houston media organization Digital Wildcatters as “a professional network and digital community for technical discussions and knowledge sharing.” After raising $5 million in seed funding led by Houston’s Mercury Fund last year, the company said it would shift its focus to rolling out its enterprise-level, AI-enabled solution.

Oxy officially announces CEO transition, names successor

new leader

Houston-based Occidental (Oxy) has officially announced its longtime CEO's retirement and her successor.

Oxy shared last week that Vicki Hollub will retire June 1. Reuters first reported Hollub's plan to retire in March, but a firm date had not been set. Hollub will remain on Oxy's board of directors.

Richard Jackson, who currently serves as Oxy's COO, will replace Hollub in the CEO role.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years," Hollub shared in a news release. "Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition. “I look forward to supporting Richard and the Board through my continued role as a director.”

Hollub has held the top leadership position at Oxy since 2016 and has been with the energy giant for more than 40 years. Before being named CEO, she served as COO and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Hollub also played a key role in leading Oxy's future as a "carbon management company."

Jackson has been with Oxy since 2003. He has held numerous leadership positions, including president of U.S. onshore oil and gas, president of low carbon integrated technologies, general manager of the Permian Delaware Basin and enhanced oil recovery oil and gas, vice president of investor relations, and vice president of drilling Americas.

He was instrumental in launching Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others, according to the company. He also serves on the Oil and Gas Climate Initiative’s Climate Investment Board and the American Petroleum Institute’s Upstream Committee. He holds a bachelor's degree in petroleum engineering from Texas A&M University.

Jackson was named COO of Oxy in October 2025. In his new role as CEO, he will also join the board of directors, effective June 1.

“I am grateful to be appointed President and CEO of Occidental and excited about the opportunity to execute from the strong position and capabilities that we built under Vicki’s leadership,” Jackson added in the release. “It means a lot to me personally to be a part of our Occidental team. I am committed to delivering value from our significant and high-quality resource base. We have a tremendous opportunity to focus on organic improvement and execution to deliver meaningful value for our employees, shareholders and partners.”

Texas data center proposed by U.S. Army could use more power than El Paso

Big Data

The U.S. Army is proposing developing a gargantuan, 3-gigawatt data center complex on Fort Bliss property that within a few years would consume more electricity than all of El Paso Electric’s 460,000 customers combined – even as questions about its development, water usage and air pollution remain unanswered.

If built, it would be the third major data center project in the El Paso region, along with Meta Platform’s $10 billion facility in Northeast and the $165 billion Project Jupiter campus that Oracle and OpenAI are building in Santa Teresa, New Mexico. The combined scale and size of the three facilities could quickly transform the Borderland into one of the nation’s core hubs of power generation and AI infrastructure.

The publicly-traded investment firm Carlyle Group would pay to build and operate the Fort Bliss data center – one of several planned in a national rollout under President Donald Trump’s administration to rapidly increase artificial intelligence technology for the Department of Defense.

At Fort Bliss, the Army is “targeting an initial operating capacity of about 100 megawatts on the compute side” by next year, David Fitzgerald, deputy undersecretary of the Army, said during a meeting with reporters April 22. An official estimated cost for the project has yet to be released.

By 2029, the complex on military land in far East El Paso would require 3 gigawatts of electricity, Fitzgerald said. By comparison, El Paso Electric currently maintains about 2.9 gigawatts of generation capacity across its entire system that spans from Hatch, New Mexico, to Van Horn, Texas. The highest customer demand the power company has ever seen was just over 2.3 gigawatts during the summer of 2023.

And whether most El Pasoans are on board with the rapid buildout of another data center here is not a question that Army leadership is asking at this point.

“What we’re trying to do is find where are the common interests, common ground that we can solve for?” Fitzgerald said, referring to coordinating with El Paso city leaders on the data center project.

“The state of modern warfare and future warfare is largely going to depend on the ability to capture, process and utilize massive amounts of data,” he said. “So, the reality is, this is a strategic priority, not just for the Army, but for the entire Department of War. So, we need these capabilities, and we need to put them somewhere.”

Combined-cycle natural gas turbines are the “most likely” source of electricity generation for the facility, said Jeff Waksman, an assistant secretary of the Army and former member of Trump’s first administration.

Waksman said the facility would undergo environmental review before construction starts.

Still, there are far more outstanding questions than answers about the proposed Fort Bliss data center.

It’s unclear if the facility would connect to El Paso Water’s water system. The city-owned water utility pointed out that Fort Bliss Water provides water service for the installation. However, El Paso Water can provide “backup” service to the base, according to the project solicitation documents.

“EPWater was just recently brought into the discussion, and we only have preliminary information,” El Paso Water said in a statement. “The construction and water use would be entirely on federal property.”

El Paso Electric said it’s also uncertain whether the data center will connect to the utility’s power grid and will figure that out in the future. To date, the Army hasn’t made a formal request for service from El Paso Electric.

Officials from the U.S. Army “confirmed that questions regarding the power source and whether it will be connected to the regional grid remain under review and have plans to establish a data center with a projected demand of 3 gigawatts,” El Paso Electric said in a statement. “Ultimately, decisions about these matters will be made by Fort Bliss leadership, and we defer to them for further comment.”

A representative with Carlyle Group at a recent community meeting didn’t answer questions or provide details about the proposed data center facility and the related power generation source.

Carlyle Group did not respond to a request for comment.

Army officials said they don’t yet have a definitive agreement in place with Carlyle, which was conditionally selected to enter into exclusive negotiations, so few details are finalized.

However, the Army has set a short timeline to start operating by late 2027. That means construction will have to start soon, Fitzgerald said.

“The ideal endstate is that we would be at least (operational) by the end of ’27, which is moving pretty quick,” Fitzgerald said. “That would mean construction would need to begin in the not-so-distant future.”

Water, electricity concerns

Meeting three gigawatts of electricity demand with natural gas-fired turbines – cited by Army officials as the most likely power source – would likely produce huge amounts of greenhouse gases in a central area of El Paso, such as carbon dioxide, as well as other harmful pollutants including particulate matter.

And even if the data center doesn’t take service from El Paso Water and instead receives water from wells managed by Fort Bliss, it would rely on groundwater pumped out of the Hueco Bolson aquifer, the city’s main source of water.

The solicitation issued by the Army cites water risk for El Paso as “extremely high” and notes that most of Fort Bliss’ water supply comes from wells within the installation.

Fitzgerald said the Army is aware of the public’s concern that the data center could unsustainably guzzle El Paso’s groundwater to cool the data center’s computer servers. He said the facility will be “water neutral.”

It’s also not clear how the project could replace the same amount of water that it consumes.

It’s possible the Kay Bailey Hutchison Desalination Plant – co-owned by El Paso Water and the U.S. Army – could play a role in making the data center water neutral. But El Paso Water said it has no details about how the data center facility could achieve water neutrality.

El Paso Water is “more than willing to continue to share ideas for best practices in sustainability to help protect our regional water resources,” the utility said in its statement.

As far as electricity generation, Army officials said they don’t know if El Paso Electric would build a new power plant to serve the data center. It’s also possible that Carlyle Group or another private company could build its own power generation source for the data center that’s isolated from the power grid El Pasoans use every day.

“We have to decide whether El Paso Electric is going to be the ones building whatever is coming, or if this is going to be some independent power producer,” Waksman said.

El Paso Electric is planning to develop a 366 megawatt power plant made up of over 800 small gas generators to power Meta’s data center. The utility will build more generation in the coming years to meet 1 gigawatt of total demand from Meta’s facility. Meanwhile, as the technology giant Oracle develops Project Jupiter, the company said Monday it is seeking to power the campus using 2.45 gigawatts of fuel cell power systems provided by the company Bloom Energy.

For perspective, 3.45 gigawatts – the combined projected demand of those two major data centers – is enough electricity to power as many as a million homes, depending on the time of day and weather.

The Fort Bliss project would have to meet environmental regulatory requirements, and the developer needs to include a plan for providing utilities and infrastructure needs such as access to the facility, according to a request for proposals issued by the Army in December 2025. Army officials emphasized the project would not impact El Pasoans’ water or electric bills.

Who is Carlyle Group?

Carlyle Group is a global investment management firm that oversees $477 billion of assets from entities such as pension funds.

The company invests that money by buying businesses ranging from wine producers to Asian telecommunications companies, or by developing infrastructure projects such as renewable energy generation and data centers. The company in 2025 posted distributable earnings of nearly $1.7 billion on $4.8 billion in revenue.

The Army wants to build the facility at Fort Bliss in partnership with Carlyle because the installation has a large amount of available, unused land and because of the water and electricity infrastructure already in place in El Paso, Fitzgerald said.

The Carlyle data center planned for El Paso is part of a wider U.S. military effort to quickly build infrastructure that supports the use of artificial intelligence — both on the battlefield and in running its day-to-day operations, according to government documents.

Army officials nodded to the use of AI in drone warfare and targeting systems. And a hyperscale data center facility can also securely house information such as the military’s cloud database that details pay and entitlements for every U.S. soldier, said Maj. Gen. Curtis Taylor, commanding general of the 1st Armored Division and Fort Bliss.

Data centers are “essential parts of power projection,” Taylor said. “But we have to protect those servers. And that’s why there’s great utility in building that infrastructure on military installations.”

The Fort Bliss facility would be located on a plot of land near the intersection of Loop 375 and Montana Avenue. The site is just east of the Camp East Montana immigrant detention facility, and near El Paso Electric’s gas-fired Montana power station.

The plan is for Carlyle to utilize the majority of the data center’s capacity for its business needs, and the military would have access to a more secure portion of the data center for its own uses.

The Army is developing another similar data center project in Dugway, Utah. Other Army bases identified as potential sites include Fort Hood in Texas and Fort Bragg in North Carolina.

The U.S. Air Force in October issued a solicitation saying it is “accepting proposals for the development of Artificial Intelligence data centers,” on unused land at different bases, including in California, Georgia, Arizona and Tennessee. The push was enabled by executive orders signed by Trump that seek to speed up permitting and development timelines for AI data centers.

Would the Fort Bliss data center pay taxes?

A privately-financed data center on Fort Bliss would likely have to pay some taxes – unlike on-base government facilities – but there’s a lot of uncertainty.

Carlyle Group is leasing the land for the data center under an “enhanced use lease” that allows branches of the military to rent under-used land on bases.

Land on federal installations is not subject to state or local taxes. However, the statute that authorizes the U.S. military to lease excess land to private entities says that “the interest of a lessee of property leased under this section may be taxed by State or local governments.”

So, while the land the data center is built on would not be subject to taxation, the structures housing the data center could be subject to local property taxes.

But it depends on how the deal is structured, including factors such as whether Carlyle or the Army ultimately takes ownership of the buildings.

The Army in January awarded a contract to Korean-owned Hanwha Defense USA, which will invest $1.3 billion to develop a munitions factory at a base in Pine Bluff, Arkansas, using an enhanced use lease.

Fitzgerald, the Army undersecretary, acknowledged the public pushback to other data centers such as Meta and Project Jupiter. But he said the Army wants to ensure the project is developed “the right way.”

“There are always elements that will kind of make this an ‘us versus them’ sort of a construct, but I don’t think we view it that way from the Army,” he said. “I think there’s a path here that will benefit not just the installation, but the community as well.”
