Solar power and battery storage are saving Texans hundreds of millions of dollars on their electric bills, the president and CEO of the Solar Energy Industries Association recently told a congressional committee.

Abigail Ross Hopper, the association’s president and CEO, said in testimony given to the U.S. Senate Environment and Public Works Committee that states like Texas that are adding significant capacity for solar power and battery storage are enjoying lower, more stable prices for electricity.

“Unsubsidized solar is now the cheapest source of electricity in history in much of the country,” Hopper said. “With no fuel costs, solar provides a hedge against natural gas price volatility that continues to cause electricity price spikes.”

“The only way to put downward pressure on prices is by bringing more power online, not less,” she added.

To illustrate the value of solar power and battery storage, Hopper compared two hot summer days in Texas—one in July 2022 and the other in July 2025.

Hopper explained that the Electric Reliability Council of Texas (ERCOT) had begun installing solar on its grid in 2022 but had very little battery storage. ERCOT manages 90 percent of the state’s electrical load.

When ERCOT grid conditions buckled under high demand on the highlighted day in 2022, the price of electricity spiked to nearly $1,500 per megawatt-hour, Hopper said.

“Three years later, the amount of solar had increased substantially and was complemented by energy storage,” she said.

On the specified day in 2025, under even greater demand than three years earlier, sizable amounts of solar power, battery storage and wind power kept ERCOT’s midday price of electricity low and stable—around $50 per megawatt-hour. That dollar amount represented a nearly 100 percent decrease compared with the highlighted day in 2022.

Solar and wind supplied nearly 40 percent of Texas’ power during the first nine months of 2025, according to the U.S. Energy Information Administration (EIA).

Despite the state’s expansion of solar power and battery storage capacity, residential electricity prices in ERCOT’s territory rose 30 percent from 2020 to 2025 and are expected to climb another 29 percent from 2025 to 2030, according to a forecast from the Texas Energy Poverty Research Institute.

The increase in electric bills is tied to factors such as:

Higher natural gas prices
Greater demand from AI data centers and cryptomining facilities
Extreme weather
Population growth
Development of new transmission and distribution lines

The strain on ERCOT’s grid is only getting worse. An EIA forecast predicts demand for ERCOT electricity will jump 9.6 percent in 2026, and ERCOT expects a 50 percent jump in demand by 2029.

Solar surpasses coal to become ERCOT’s third-largest power source in 2025

by the numbers

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.

Report: Texas expected to shine as top state for solar installations in 2023

fourth quarter push

When all the numbers are tallied, 2023 should be a very sunny year for solar installations in Texas.

The Solar Energy Industries Association, SEIA, and energy research and consulting firm Wood Mackenzie predict Texas will be the top state for solar installations in 2023. In the fourth quarter, Texas is expected to add about 3.7 gigawatts of solar capacity — more than the combined total for the previous three quarters.

In 2021, Texas added nearly 6.07 gigawatts of solar capacity, with that figure falling to more than 3.66 gigawatts in 2022. But for 2023, SEIA and Wood Mackenzie anticipate Texas having added almost 6.24 gigawatts of solar capacity for residential, business, and utility customers.

A report released last week by SEIA and Wood Mackenzie indicates that sales volume for solar installations has declined in Texas and some other states due in part to higher costs for financing solar equipment. Solar sales volume in Texas started dropping off in late 2022 and has continued to shrink, says the report.

Wood Mackenzie forecasts 13 percent growth for the U.S. residential solar market in 2023. The report predicts the U.S. will have added 33 gigawatts of residential solar capacity in 2023, up from a record-setting 6.5 gigawatts in 2022. The U.S. added 6.5 gigawatts of residential solar capacity in the third quarter of 2023 alone, says the report.

“Solar remains the fastest-growing energy source in the United States, and despite a difficult economic environment, this growth is expected to continue for years to come,” says Abigail Ross Hopper, president and CEO of SEIA. “To maintain this forecasted growth, we must modernize regulations and reduce bureaucratic roadblocks to make it easier for clean energy companies to invest capital and create jobs.”

Solar accounted for nearly half (48 percent) of all new electric-generating capacity during the first three quarters of 2023, bringing total installed solar capacity in the U.S. to 161 gigawatts across 4.7 million installations. By 2028, U.S. solar capacity is expected to reach 377 gigawatts, enough to power more than 65 million homes.

“The U.S. solar industry is on a strong growth trajectory, with expectations of 55 percent growth this year and 10 percent growth in 2024,” says Michelle Davis, head of solar research at Wood Mackenzie.

“Growth is expected to be slower starting in 2026 as various challenges like interconnection constraints become more acute,” she adds. “It’s critical that the industry continue to innovate to maximize the value that solar brings to an increasingly complex grid. Interconnection reform, regulatory modernization, and increasing storage attachment rates will be key tools.”

Fervo Energy leads Time’s top green tech companies of 2026

top spot

The accolades keep coming for Houston-based geothermal energy company Fervo Energy.

Fervo sits atop Time magazine’s and Statista’s 2026 list of America’s Top GreenTech Companies. Fervo ranked No. 6 on the list last year.

The ranking honors 250 companies in the U.S. based on their environmental impact, innovation and financial strength. Fervo joins five other Houston-area companies on the list.

No. 49 Quaise Energy, an MIT Energy Initiative spinout that’s developing a drilling system designed to convert existing power stations for geothermal power production
No. 71 Plus Power, which develops, owns and operates battery energy storage systems
No. 98 Utility Global, whose technology enables industrial decarbonization
No. 199 Solugen, whose technology converts plant-based feedstocks into carbon-negative chemicals
No. 215 Noodoe, which specializes in EV charging stations and software

Fervo says its approach to enhanced geothermal systems (EGS)—including horizontal drilling, AI-enabled drilling and exploration, advanced reservoir engineering, and fiber-optic sensing—demonstrates how validated technology can help deliver reliable zero-emission power.

“By applying drilling technology from the oil and gas industry, we have proven that we can produce 24/7 carbon-free energy resources in new geographies across the world,” Fervo co-founder and CEO Tim Latimer said last year.

Other recent recognitions for Fervo includes:

The 2025 Houston Innovation Awards named it Scaleup of the Year
MIT Technology Review put Fervo on its 2025 list of the 10 global climatech companies to watch
Time named Fervo one of the 100 Most Influential Companies of 2025

Fervo was among Congruent Ventures’ and Silicon Valley Bank’s 50 by 2050 companies, all of which are poised to advance global decarbonization over a 25-year span

Just last month, Fervo secured $421 million in debt financing for the construction of its 500-megawatt Cape Station geothermal project in Utah. And in December, the company landed an oversubscribed $462 million Series E round of funding, pushing its valuation to an estimated $1.4 billion. Fervo filed for an IPO earlier this year.

3 strategies to strengthen the Gulf Coast as a global energy hub

The View from HETI

The Texas-Louisiana Gulf Coast is the backbone of America’s energy and chemical economy. Texas produces roughly 43% of U.S. crude oil and 28% of natural gas, while Texas and Louisiana together account for about half of the nation’s refining capacity, processing 9.3 million barrels of crude per day across 50 refineries. The region also produces approximately 80% of the nation’s primary petrochemicals and ships more than $117 billion in chemical products annually from Texas alone.

This unmatched concentration of refining, petrochemical manufacturing, pipelines, ports, and technical talent makes the Gulf Coast one of the most critical energy hubs in the world. But maintaining that leadership in a rapidly evolving global market will require intentional collaboration, faster technology commercialization, and strengthened supply chain resilience.

In fall 2025, the Greater Houston Partnership’s Houston Energy Transition Initiative (HETI) convened national laboratories, Gulf Coast universities, and industry leaders to examine how to reinforce the region’s long-term competitiveness. Participants included Argonne, Oak Ridge, Lawrence Berkeley, the National Energy Technology Laboratory (NETL), and the National Laboratory of the Rockies, alongside Gulf Coast academic institutions and energy and chemical companies. Here are the key findings and takeaways from the workshop.

1. Supply Chain Resilience Requires Structured Industry–Lab Collaboration

Resilience—diversity of supply, operational flexibility, and rapid recovery—was a recurring theme. Recent disruptions exposed vulnerabilities in tightly interconnected energy and manufacturing systems.

National laboratories provide capabilities that complement Gulf Coast industrial scale, particularly at early and mid technology readiness levels (TRLs 1–7), before full commercial deployment. Examples include:

Advanced manufacturing and AI-enabled validation of critical components (Oak Ridge).
Materials scale-up and techno-economic modeling to move from lab discovery to industrial relevance (Argonne).
Pilot-scale testing for severe-service alloys, chemical conversion, and process innovation (NETL).
Integrated energy systems modeling to assess grid resilience and system disruptions (National Laboratory of the Rockies).

Recommendation: Organize targeted Gulf Coast industry missions to national laboratories focused on critical supply chains—power equipment, high-heat industrial processes, novel catalysts, refining, and grid infrastructure—to identify joint development opportunities and reduce time to commercialization.

2. Modeling, AI, and Open-Access Platforms Can Bridge the Technology Gap

A persistent barrier to innovation is the gap between scientific discovery, applied development, and commercial deployment. Universities often operate at TRLs 1–3, national labs at 1–7, and industry at 7–9. Bridging these silos requires shared modeling tools, high-performance computing, and structured feedback loops.

National labs maintain open-access platforms capable of:

Simulating grid expansion, investment, and dispatch decisions.
Modeling cradle-to-gate industrial material flows.
Optimizing complex energy and chemical systems.
De-risking carbon capture, critical mineral recovery, and advanced manufacturing integration.

Recommendation: HETI should convene structured training and feedback sessions on these public modeling platforms—ensuring Gulf Coast industry can apply, improve, and help guide further development of tools critical to regional competitiveness. Federal initiatives such as the Genesis Mission, focused on AI-accelerated scientific discovery, further expand opportunities for Gulf Coast participation.

3. Time to Commercialization Is the Ultimate Competitive Metric

The lithium-ion battery is a cautionary example: while pioneered in U.S. labs, large-scale manufacturing leadership shifted overseas. Without strategic intervention, U.S. firms are projected to capture less than 30% of domestic lithium battery cell value by 2030.

Successful DOE-backed consortium models show that mission-aligned, multi-partner collaboration reduces development timelines and strengthens domestic manufacturing know-how. However, public–private partnership mechanisms such as CRADAs and Strategic Partnership Projects can be time-intensive.

Recommendation: The Gulf Coast should actively engage DOE and national laboratories to streamline public–private partnership pathways, improve intellectual property clarity, and expand industry access to laboratory infrastructure.

The Path Forward: A Gulf Coast Consortium Model
The workshop’s central conclusion was clear: the Gulf Coast should formalize collaboration through a regional industry–academia–laboratory consortium.

Such a model could:

Co-locate national lab researchers within the region.
Share modeling data and analytical capabilities.
Establish open-access pilot facilities that complement lab infrastructure.
Harmonize IP frameworks to accelerate licensing and deployment.

With its dense industrial ecosystem, technical workforce, and decision-making concentration, the Gulf Coast is uniquely positioned to serve as a national demonstration hub for advanced energy and chemical manufacturing.

If industry, universities, and national laboratories align around a shared regional strategy, the Gulf Coast can:

Accelerate commercialization timelines.
Strengthen critical supply chains.
Unleash a world-class technical workforce.
Reinforce U.S. leadership in strategic energy and chemical sectors.
