Solar barely eclipsed coal to become the third biggest source of energy generated for the Electric Reliability Council of Texas (ERCOT) in 2025, according to new data.

In 2024, solar represented 10 percent of energy supplied to the ERCOT electric grid. Last year, that number climbed to 14 percent. During the same period, coal’s share remained at 13 percent.

From the largest to smallest share, here’s the breakdown of other ERCOT energy sources in 2025 compared with 2024:

  • Combined-cycle gas: 33 percent, down from 35 percent in 2024
  • Wind: 23 percent, down from 24 percent in 2024
  • Natural gas: 8 percent, down from 9 percent in 2024
  • Nuclear: 8 percent, unchanged from 2024
  • Other sources: 1 percent, unchanged from 2024

Combined, solar and wind accounted for 37 percent of ERCOT energy sources.

Looking ahead, solar promises to reign as the star of the ERCOT show:

  • An ERCOT report released in December 2024 said solar is on track to continue outpacing other energy sources in terms of growth of installed generating capacity, followed by battery energy storage.
  • In December, ERCOT reported that more than 11,100 megawatts of new generating capacity had been added to its grid since the previous winter. One megawatt of electricity serves about 250 homes in peak-demand periods. Battery energy storage made up 47 percent of the new capacity, with solar in second place at 40 percent.

The mix of ERCOT’s energy is critical to Texas’ growing need for electricity, as ERCOT manages about 90 percent of the electric load for the state, including the Houston metro area. Data centers, AI and population growth are driving heightened demand for electricity.

In the first nine months of 2025, Texas added a nation-leading 7.4 gigawatts of solar capacity, according to a report from data and analytics firm Wood Mackenzie and the Solar Energy Industries Association.

“Remarkable growth in Texas, Indiana, Utah and other states ... shows just how decisively the market is moving toward solar,” says Abigail Ross Hopper, president and CEO of the solar association.

Energy truly IS everywhere according to ChatGPT

EVERYDAY ENERGY

I sat down to have a conversation with ChatGPT from OpenAI about energy by-products; specifically, everyday items we use that contain some form of petrochemicals. My first prompt was rather broad, so I wasn’t surprised to get back a rather broad answer highlighting product categories instead of specific examples. Plastics, synthetic fibers, cleaning products, personal care products, medicines, paints & coatings, and adhesives were all succinctly summarized, but I wanted to dive deeper.

Given that AI has an almost limitless reach, I asked for a comprehensive list of all the products we use in everyday life that are made from petrochemicals. Turns out, ChatGPT has some healthy boundaries, so it pushed back, only offering a slightly more detailed list of the categories produced from the first prompt.

Not to be deterred, I asked for additional examples. I didn’t want to continue getting spoon-fed 10 items at a time, so I asked for 200. Less than comprehensive, more than the crumbs I was getting.

In entertaining fashion, ChatGPT told me compiling a list of 200 items might be challenging, but that it could offer up 100. The brazen negotiation made me smile.

I complimented the list and nudged a bit, encouraging ChatGPT it could come up with another 100 items if it tried. Much like a teenager wishes to stave off further questioning from a nosy parent, ChatGPT proffered up a second response of 100 items–almost half of which were simply things before which it added the qualifier “synthetic.” Salty.

As my intention is not to bore you, but rather enhance the knowledge of our readers by understanding how pervasive petrochemical products are in our everyday life, I settled on a more direct inquiry with a capped demand prompt: “What would you say are the 10 most surprising things in common everyday use that contain petrochemical products?”

Most of the answers featured wax-based products, like lotions, crayons, and lipstick–not necessarily earth-shattering realizations given my familiarity with cosmetics as petroleum by-products. I was pleasantly surprised to learn that chewing gum, with its synthetic rubber base enabling theoretically endless chewing, is derived from petroleum. I was also surprised to learn that many artificial sweeteners, like saccharin and aspartame, are made from petrochemicals. Huh.

There was one item on the list, however, that helped me see how truly pervasive the energy industry is, and not just for petrochemicals. Tucked in nonchalantly at #6 was Deodorant. My brain jumped immediately to the waxy base of a solid sweat deterrent, but my eyes got a curveball. ChatGPT writes, “Many deodorants contain aluminum, which is often derived from bauxite, a mineral that is usually mined from the earth using petroleum-powered machinery.” Now that was an answer I wasn’t expecting.

While my initial inference stood true – the smooth glide of a buttery solid antiperspirant is without a doubt derived from petrochemicals (not to mention the plastic packaging surrounding it), I wasn’t expecting ChatGPT to rope in the oft petroleum-fueled tools used to make said product. If that’s true, then nearly every item on the planet is derived from petroleum. Or at the very least, some source of energy. Regardless of whether the machinery used runs on gasoline, electricity, or wind power, literally almost everything that is produced on this earth is related to the energy industry.

Even if it’s hand-made, it’s technically still energy-adjacent, assuming we all bathe regularly with soap, yet another on the list of commonly used items derived from petroleum by-products. It’s certainly directly powering some manual activities, for those busting stress and bad breath with gum, or drinking a diet soda to power through. No pun intended.

I share this amusing tale simply to clarify the ubiquitous nature of energy in all parts of the modern world. As we look toward the #futureofenergy, we must be cognizant of its universal reach. It’s not necessarily realistic to switch from one source of energy to another overnight, but we do have a responsibility to seek cleaner, healthier, more efficient sources of energy while sustaining the life to which we have all grown accustomed.

Much like ChatGPT thought she couldn’t come up with 200 items derived from petroleum products, many think Houston will be unable to drive the Energy Transition, given our extensive petroleum focus. But like so many fellow Houstonians before us, we love a good challenge.

Just keep prompting us, and we’ll eventually unlock infinite potential for the #futureofenergy. It’s a limitless time to be in Houston, absorbing wisdom the city so willingly wants to share with the growing ecosystem of innovators. Just ask the growing number of almost 5,000 Energy-related firms in Houston. We’re just getting started.

Texas awards $73M for Houston-area grid resilience project

grid funding

Texas Gov. Gregg Abbott announced millions in funding for energy resilience projects around this state this week, with one major project set to impact the greater Houston area.

As part of the Texas Energy Fund's Outside of ERCOT Grant Program, the state announced a roughly $73 million agreement with the Sam Houston Electric Cooperative to replace and upgrade more than 9,000 electric poles and improve other equipment in Montgomery, Liberty and Hardin counties. The agreement is the first for the fund's Outside of ERCOT Grant Program, which supports state projects outside of the state's largest grid.

The multibillion-dollar Texas Energy Fund aims to "finance the construction, maintenance, and modernization of electric facilities across Texas." It was approved by voters in 2023. Other programs within the fund include the:

  • In-ERCOT Generation Loan Program
  • Completion Bonus Grant Program
  • Texas Backup Power Package Program

“The Texas Energy Fund delivers real results for Texans and strengthens the electric systems that families, businesses, and communities depend on,” Abbott said in a news release. “This grant to Sam Houston Electric Cooperative will replace thousands of vulnerable utility poles to better withstand severe weather and ensure a more reliable and resilient grid in East Texas.”

The Houston-area project, nicknamed Steel Anchor, is expected to be completed by June 2031. According to the release from the governor's office, the Sam Houston Electric Cooperative’s territory is one of the most hurricane-prone service areas in the state. The cooperative serves more than 38,000 Texas consumers

“Over the past decade, Sam Houston EC has strategically replaced poles to improve the strength of its electricity distribution system. This grant will boost the Cooperative’s ongoing grid-hardening and resiliency program,” Doug Turk, CEO of the Sam Houston Electric Cooperative, added in the release.

Following the announcement of the Sam Houston funding, Abbott's office also awarded another $200 million from the Outside of ERCOT Grant Program to upgrade approximately 700 miles of power equipment in Northeast Texas. The equipment is operated by Southwestern Electric Power Company, which serves more than 192,000 Texas consumers. The project will include improvements to 200 circuits, replacing aging copper wire with aluminum alloy conductors and replacing existing utility poles.

Additionally, the state announced its seventh Texas Energy Fund loan agreement for a 570 megawatt natural gas power plant in Sherman, Texas. The 20-year loan of up to $411 million is between the Public Utility Commission of Texas and Rayburn Electric Cooperative and is part of the fund's In-ERCOT Generation Loan Program. Rayburn will build the facility near its existing Rayburn Energy Station 1 in the Texoma region. It will connect to the ERCOT North Load Zone.

“When Texas voters overwhelmingly approved the Texas Energy Fund, they gave us a mandate to secure new, reliable power generation for Texas,” PUCT Chairman Thomas Gleeson added in a release. “The TxEF is delivering on that promise, and Rayburn Electric Cooperative’s new 570 MW power plant is proof. We are ensuring Texas families and businesses have power they can depend on for years to come.”

Solar manufacturer announces massive new facility in Houston area

coming soon

SEG Solar has announced plans to open a new 1.15 million-square-foot solar module facility in Tomball—its third in the Houston area.

The news comes just weeks after the Houston-based solar manufacturer announced its second facility, which will be located in Cypress. It’s expected to open in August.

The latest 4.6-gigawatt facility in Tomball will include an assembly factory and a warehouse. Construction is slated to wrap in March 2027, with commercial panel production planned to begin in May 2027. Once completed, the facility will bring SEG’s annual U.S. module manufacturing capacity to 10.6 gigawatts, according to a news release from the company, one of the largest totals in the country.

The facility will produce heterojunction technology (HJT) modules, which the company says will add to the number of n-type solar panels made in the U.S. HJT modules are known to be more durable and are well suited for hotter climates.

“Designed to support next-generation HJT technology and FEOC-compliant production, the facility ensures reliable, high-efficiency solar solutions,” Raymond Bailey, sales manager at SEG Solar, said in a LinkedIn post. “ Alongside upstream integration in Indonesia and potential U.S. cell manufacturing, we are strengthening supply chain resilience amid evolving trade policies.”

SEG opened its $60 million, 250,000-square-foot facility in Houston in 2024 to house its production workshops, raw material warehouses, administrative offices, finished goods warehouses, and supporting infrastructure. The continued expansion is part of SEG’s long-term goal of becoming one of the largest 100 percent U.S.-owned module manufacturers.

Houston chemical co. completes successful field trial of cleaner natural gas processing tech

successful trial

Houston-based Merichem Technologies has announced successful results from the field trial of its new hydrogen sulfide (H2S) removal technology in the Permian Basin.

The technology, known as ECOTREAT, removed more than 99 percent of hydrogen sulfide gas from natural gas streams, or “sour gas,” without producing solid waste during the month-long trial. It also showed sustained performance even when operating above the unit’s design capacity, according to a news release.

“The industry is continually seeking to reduce both the price and complexity of removing hydrogen sulfide from gas production, especially since oil production has shifted to increasingly sour sources, higher gas ratios, and higher water ratios,” Jeff Gomach, SVP, Merichem Technologies, said in a news release. “ECOTREAT met all its field trial objectives and provides a highly effective method for removing hydrogen sulfide to prevent equipment corrosion, ensure worker safety, meet environmental regulations, and maintain product quality for transport.

H2S found in natural gas can turn the gas toxic or hazardous and lead to corrosion in pipelines and processing equipment. However, standard H2S removal technologies create high levels of solid waste. ECOTREAT resolves many of those issues by using an aqueous-phase proprietary catalytic process that converts H2S into dissolved thiosulfate.

Next, Merichem says it plans to move the technology out of the pilot stage to full-scale commercialization.

Merichem, an 80-plus-year-old company, initially launched as a soap and industrial cleaning company. It eventually transitioned to focus on energy technology.

In 2024, Black Bay Energy acquired a portion of Merichem Process Technologies and Merichem Catalyst Products, which would become Merichem Technologies.
