The winds of change in power generation are sweeping through Texas.

Texas outpaced all other states in various categories of power generation in 2024, according to a new report from Ember, an energy think tank. The report shows:

  • Texas contributed more (12 terawatt-hours) to the country’s 64 terawatt-hour rise in solar generation last year than any other state.
  • Texas installed more solar (7.4 gigawatts) and battery (3.9 gigawatt) capacity than any other state.
  • Texas installed more utility-scale battery capacity (3.9 gigawatts) than any other state.
  • Texas saw the second biggest increase (eight terawatt-hours) in natural gas generation in 2024. Only Virginia, at 10 terawatt-hours, ranked higher.
  • Texas ranked second among the states for the biggest drop in production of coal-fueled power (6.07 terawatt-hours), preceded only by Wyoming (6.3 terawatt-hours).

Overall, coal represented 14 percent of power generation in Texas last year, with the combination of wind and solar at 30 percent, according to the report. Across the U.S., says the report, wind and solar generated more electricity than coal for the first time. Coal generation made up just 15% of U.S. electricity generation in 2024.

“The shift away from coal has been primarily driven by market dynamics and availability of more cost-effective resources,” the report says. “The unit costs of wind and solar have reduced significantly and their quick installation makes them commercially attractive.”

Citing data like the figures published by Ember, Texas Gov. Greg Abbott champions Texas as the “Energy Capital of the World,” a title that Houston also claims.

“As Texas continues to experience unprecedented growth, we will remain a leader in energy while also bolstering the Texas grid to meet the growing demands of our great state,” Abbott said in 2024.

Report: Texas solar power, battery storage helped stabilize grid in summer 2024, but challenges remain

by the numbers

Research from the Federal Reserve Bank of Dallas shows that solar power and battery storage capacity helped stabilize Texas’ electric grid last summer.

Between June 1 and Aug. 31, solar power met nearly 25 percent of midday electricity demand within the Electric Reliability Council of Texas (ERCOT) power grid. Rising solar and battery output in ERCOT assisted Texans during a summer of triple-digit heat and record load demands, but the report fears that the state’s power load will be “pushed to its limits” soon.

The report examined how the grid performed during more demanding hours. At peak times, between 11 a.m. and 2 p.m. in the summer of 2024, solar output averaged nearly 17,000 megawatts compared with 12,000 megawatts during those hours in the previous year. Between 6 p.m. and 9 p.m., discharge from battery facilities averaged 714 megawatts in 2024 after averaging 238 megawatts for those hours in 2023. Solar and battery output have continued to grow since then, according to the report.

“Batteries made a meaningful contribution to what those shoulder periods look like and how much scarcity we get into during these peak events,” ERCOT CEO Pablo Vegas said at a board of directors conference call.

Increases in capacity from solar and battery-storage power in 2024 also eclipsed those of 2023. In 2023 ECOT added 4,570 megawatts of solar, compared to adding nearly 9,700 megawatts in 2024. Growth in battery storage capacity also increased from about 1,500 megawatts added in 2023 to more than 4,000 megawatts added in 2024. Natural gas capacity also saw increases while wind capacity dropped by about 50 percent.

Texas’ installation of utility-scale solar surpassed California’s in the spring of last year, and jumped from 1,900 megawatts in 2019 to over 20,000 megawatts in 2024 with solar meeting about 50 percent of Texas' peak power demand during some days.

While the numbers are encouraging, the report states that there could be future challenges, as more generating capacity will be required due to data center construction and broader electrification trends. The development of generating more capacity will rely on multiple factors like price signals and market conditions that invite more baseload and dispatchable generating capacity, which includes longer-duration batteries, and investment in power purchase agreements and other power arrangements by large-scale consumers, according to the report.

Additionally, peak demand during winter freezes presents challenges not seen in the summer. For example, in colder months, peak electricity demand often occurs in the early morning before solar energy is available, and it predicts that current battery storage may be insufficient to meet the demand. The analysis indicated a 50% chance of rolling outages during a cold snap similar to December 2022 and an 80% chance if conditions mirror the February 2021 deep freeze at the grid’s current state.

The report also claimed that ERCOT’s energy-only market design and new incentive structures, such as the Texas Energy Fund, do not appear to be enough to meet the predicted future magnitude and speed of load growth.

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.

Tesla sales tumble 13% as Musk backlash, competition and aging lineup turn off buyers

Tesla Talk

Tesla sales fell 13% in the first three months of the year, another sign that Elon Musk’s once high-flying electric car company is struggling to attract buyers.

The double-digit drop is likely due to a combination of factors, including its aging lineup, competition from rivals and a backlash from Musk’s embrace of right wing politics. It also is a warning that the company’s first-quarter earnings report later this month could disappoint investors.

Tesla reported deliveries of 336,681 globally in the January to March quarter. The figure was down from sales of 387,000 in the same period a year ago. The decline came despite deep discounts, zero financing and other incentives.

Analysts polled by FactSet expected much higher deliveries of 408,000.

Dan Ives of Wedbush said in a note to clients that Tesla is seeing soft demand in the United States and China, as well as facing pressure in Europe.

“The brand crisis issues are clearly having a negative impact on Tesla...there is no debate,” he said.

Ives said that Wall Street financial analysts knew the first-quarter figures were likely to be bad, but that it was even worse than expected, calling them a “disaster on every metric.”

The sales drop came three weeks after President Donald Trump held an extraordinary press conference outside the White House in which he praised Tesla, blasted boycotts against the company and bought a Tesla himself while TV cameras rolled in an effort to help lift sales.

“I don’t like what’s happening to you,” said Trump, before slipping into a red Model S and exclaiming, “Wow. That’s beautiful.”

After falling as much as 6% in early Wednesday, Tesla stock shot up more than 5% in afternoon trading after a report from Politico, citing anonymous sources, that Musk may soon step down from leadership of his Department of Government Efficiency, the cost-cutting group that has led to tens of thousands of federal workers losing their jobs.

Tesla investors have complained the DOGE work has diverted Musk's focus from Tesla, where he is the CEO. On Tuesday, New York City's comptroller overseeing pension funds down $300 million this year on Tesla holdings called for a lawsuit accusing a distracted Musk of "driving Tesla off a financial cliff.”

Tesla’s stock has plunged by roughly half since hitting a mid-December record as expectations of a lighter regulatory touch and big profits with Donald Trump as president were replaced by fear that the boycott of Musk's cars and other problems could hit the company hard.

Analysts are still not sure exactly how much the fall in sales is due to the protests or other factors. Electric car sales have been sluggish in general, and Tesla in particular is suffering as car buyers hold off from buying its bestselling Model Y while waiting for an updated version.

Still, even bullish financial analysts who earlier downplayed the backlash to Musk’s polarizing political stances are acknowledging that it is hurting the company, something that Musk also recently acknowledged.

“This is a very expensive job,” Musk said at a Wisconsin rally on Sunday, referring to his DOGE role. “My Tesla stock and the stock of everyone who holds Tesla has gone roughly in half."

The protests come as the Austin, Texas electric vehicle maker faces fierce competition from other EV makers offering vastly improved models, including those of BYD. The Chinese EV giant unveiled in March a technology that allows it cars to charge up in just five to eight minutes.

Tesla is expected to report earnings of 48 cents per share for the first quarter later this month, up 7% from a year earlier, according to a survey of financial analysts who the car company by research firm FactSet.

Nearly all of Tesla’s sales in the quarter came from the smaller and less-expensive Models 3 and Y, with the company selling less than 13,000 more expensive models, which include X and S as well as the Cybertruck.

Last year, Houston Energy and Climate Startup Week welcomed more than 2,000 attendees, investors and industry leaders to more than 30 events. It featured more than 100 speakers and showcased more than 125 startups.

"In 2024, we set out to build something with lasting impact—rooted in the ingenuity of Houston’s technologists and founders. Thanks to a collaborative effort across industry, academia, and startups, we’ve only just begun to showcase Houston’s strengths and invite others to be part of this movement," Stricker added in the release. "We can’t wait to see the city rise to the occasion again in 2025.”

Dow aims to power Texas manufacturing complex with next-gen nuclear reactors

Clean Energy

Dow, a major producer of chemicals and plastics, wants to use next-generation nuclear reactors for clean power and steam at a Texas manufacturing complex instead of natural gas.

Dow's subsidiary, Long Mott Energy, applied Monday to the U.S. Nuclear Regulatory Commission for a construction permit. It said the project with X-energy, an advanced nuclear reactor and fuel company, would nearly eliminate the emissions associated with power and steam generation at its plant in Seadrift, Texas, avoiding roughly 500,000 metric tons of planet-warming greenhouse gas emissions annually.

If built and operated as planned, it would be the first U.S. commercial advanced nuclear power plant for an industrial site, according to the NRC.

For many, nuclear power is emerging as an answer to meet a soaring demand for electricity nationwide, driven by the expansion of data centers and artificial intelligence, manufacturing and electrification, and to stave off the worst effects of a warming planet. However, there are safety and security concerns, the Union of Concerned Scientists cautions. The question of how to store hazardous nuclear waste in the U.S. is unresolved, too.

Dow wants four of X-energy's advanced small modular reactors, the Xe-100. Combined, those could supply up to 320 megawatts of electricity or 800 megawatts of thermal power. X-energy CEO J. Clay Sell said the project would demonstrate how new nuclear technology can meet the massive growth in electricity demand.

The Seadrift manufacturing complex, at about 4,700 acres, has eight production plants owned by Dow and one owned by Braskem. There, Dow makes plastics for a variety of uses including food and beverage packaging and wire and cable insulation, as well as glycols for antifreeze, polyester fabrics and bottles, and oxide derivatives for health and beauty products.

Edward Stones, the business vice president of energy and climate at Dow, said submitting the permit application is an important next step in expanding access to safe, clean, reliable, cost-competitive nuclear energy in the United States. The project is supported by the Department of Energy’s Advanced Reactor Demonstration Program.

The NRC expects the review to take three years or less. If a permit is issued, construction could begin at the end of this decade, so the reactors would be ready early in the 2030s, as the natural gas-fired equipment is retired.

A total of four applicants have asked the NRC for construction permits for advanced nuclear reactors. The NRC issued a permit to Abilene Christian University for a research reactor and to Kairos Power for one reactor and two reactor test versions of that company's design. It's reviewing an application by Bill Gates and his energy company, TerraPower, to build an advanced reactor in Wyoming.

X-energy is also collaborating with Amazon to bring more than 5 gigawatts of new nuclear power projects online across the United States by 2039, beginning in Washington state. Amazon and other tech giants have committed to using renewable energy to meet the surging demand from data centers and artificial intelligence and address climate change.
