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.

Texas solar set to overtake coal for first time in 2026, EIA forecasts

solar on the rise

Solar power promises to shine even brighter in Texas this year.

A new forecast from the U.S. Energy Information Administration (EIA) indicates that for the first time, annual power generation from utility-scale solar will surpass annual power generation from coal across the territory covered by the Electric Reliability Council of Texas (ERCOT).

Solar generation is expected to reach 78 billion kilowatt-hours in 2026 in the ERCOT grid, compared with 60 billion kilowatt-hours for coal, the EIA forecast says. The ERCOT grid supplies power to about 90 percent of Texas, including the Houston area.

“Utility-scale solar generation has been increasing steadily in ERCOT as solar capacity additions help meet rapid electricity demand growth,” the forecast says.

Although natural gas remains the dominant source of electricity generation in ERCOT, accounting for an average 44 percent of electricity generation from 2021 to 2025, solar’s share of the generation mix rose from four percent to 12 percent. During the same period, coal’s share dropped from 19 percent to 13 percent.

EIA predicts about 40 percent of U.S. solar capacity, or 14 billion kilowatt-hours, added in 2026 will come from Texas.

Although EIA expects annual solar generation to exceed annual coal generation in 2026, solar surpassed coal in ERCOT on a monthly basis for the first time in March 2025, when solar generation totaled 4.33 billion kilowatt-hours and coal’s totaled 4.16 billion kilowatt-hours. Solar generation continued to exceed that of coal until August of that year.

“In 2026, we estimate that solar exceeded coal for the first time in March, and we forecast generation from solar installations in ERCOT will continue to exceed that from coal until December, when coal generation exceeds solar,” says EIA. “We expect solar generation to exceed that of coal for every month in 2027 except January and December.”

For 2027, EIA forecasts annual solar generation of 99 billion kilowatt-hours in the ERCOT grid, compared with 66 billion kilowatt-hours of annual coal generation.

In April, ERCOT projected almost 368 billion kilowatt-hours of demand in ERCOT’s territory by 2032. ERCOT’s all-time peak demand hit 85.5 billion kilowatt-hours in August 2023.

“Texas is experiencing exceptional growth and development, which is reshaping how large load demand is identified, verified, and incorporated into long-term planning,” ERCOT President and CEO Pablo Vegas said. “As a result of a changing landscape, we believe this forecast to be higher than expected … load growth.”

Houston startup raises $6M to grow AI platform for solar, battery contractors

fresh funding

Houston tech startup Artemis has raised $6 million from 10 investors. The company offers an AI-supported platform that enables solar, battery storage and home improvement contractors to design, sell and finance energy projects.

Long Journey and Copec WIND Ventures co-led the round, with participation from angel investor Scott Banister, Coalition Operators, FJ Labs, Ludlow Ventures, Palm Tree Crew, Plug and Play Ventures, Shrug Capital and Tribeca Ventures.

To help propel growth, the company secured $10 million in financing last year (under its previous name, Monalee) from venture debt and growth credit provider Applied Real Intelligence. As Monalee, the company raised $16 million in venture capital.

The company was founded in 2022 as an installer of solar and battery storage projects. Five years later, the startup used in-house technology to establish its standalone software platform as it began pivoting away from installation. The company recently adopted the Artemis brand name.

Artemis says its platform saves time and money for installers of residential solar, battery storage, and energy projects. The platform combines an AI-powered design tool with embedded financing capabilities and compliance automation to create a single operating system.

The company says its customers report as much as a 72 percent reduction in software costs and up to 98 percent faster turnaround times. Thus far, more than 100 installers are using Artemis’ technology.

“Installers shouldn’t need six tools and a week of back-and-forth to sell a project," Walid Halty, co-founder and CEO of Artemis, said in a press release. “This funding gives us the fuel to scale our mission to compress design, financing, and compliance into a single flow so every installer can operate like a modern energy company. We’re not just speeding up deals, we're modernizing how distributed energy gets built.”

The Artemis platform, now available in the U.S. and soon to be launched in Latin America, caters to home improvement contractors, solar companies, lenders, and utilities.

“Artemis is transforming the complexity of distributed energy into elegant simplicity," added Arielle Zuckerberg, general partner at Long Journey.

Project SunRope, a 347-megawatt solar project outside of Houston, has landed $394 million in construction financing.

The project, located in Wharton County, about 60 miles outside of Houston, is slated to begin commercial operation in Q3 2027 and aims to support emission reductions, grid reliability and affordability in one of the highest electricity-demand regions in Texas and the U.S. It’s being developed through a joint venture between San Antonio-based OCI Energy and leading Israeli solar company Arava Power. New York-based ING Capital underwrote the financing package.

“The close of construction financing for Project SunRoper represents an important milestone for OCI Energy and our partners,” Sabah Bayatli, resident of OCI Energy, said in a news release. “This transaction reflects our continued commitment to deliver high-quality, utility-scale solar projects that strengthen grid reliability and provide affordable energy infrastructure.”

The construction financing is supported by a 20-year power purchase agreement with a Fortune 100 company, according to the release. Other collaborators include BHI and Bank of Hapoalim, which provided financing support and letters of credit to support the development of the project.

This is the second transaction between OCI Energy and ING, as they previously worked together on financing for the Alamo City Battery Energy Storage System, a 120-megawatt battery energy storage system under development in Bexar County.

“This project exemplifies the high‑quality renewable infrastructure we seek to finance – a strong sponsor partnership, a long‑term contracted revenue profile, and a well‑located asset in one of the most dynamic power markets in the United States,” Sven Wellock, managing director at ING, added in the release. “We are proud to build on our existing relationship with OCI Energy and to partner with Arava Power on its continued expansion in the U.S. market, advancing a project that will deliver reliable, affordable clean energy for years to come.”

OCI Energy operates several utility-scale solar and battery energy storage system projects outside of the San Antonio area, as well as in Georgia and New Jersey. It has five other projects under construction outside of San Antonio and Waco, with more than 20 under development throughout the state.

Houston-based ENGIE to add new wind and solar projects to Texas grid

coming soon

Houston-based ENGIE North America Inc. has expanded its partnership with Los Angeles-based Ares Infrastructure Opportunities to add 730 megawatts of renewable energy projects to the ERCOT grid.

The new projects will include one wind and two solar projects in Texas.

“The continued growth of our relationship with Ares reflects the strength of ENGIE’s portfolio of assets and our track record of delivering, operating and financing growth in the U.S. despite challenging circumstances,” Dave Carroll, CEO and Chief Renewables Officer of ENGIE North America, said in a news release. “The addition of another 730 MW of generation to our existing relationship reflects the commitment both ENGIE and Ares have to meeting growing demand for power in the U.S. and our willingness to invest in meeting those needs.”

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada, and 52.7 gigawatts worldwide. The company is targeting 95 gigawatts by 2030.

ENGIE launched three new community solar farms in Illinois since December, including the 2.5-megawatt Harmony community solar farm in Lena and the Knox 2A and Knox 2B projects in Galesburg.

The company's 600-megawatt Swenson Ranch Solar project near Abilene, Texas, is expected to go online in 2027 and will provide power for Meta, the parent company of social media platform Facebook. Late last year, ENGIE also signed a nine-year renewable energy supply agreement with AstraZeneca to support the pharmaceutical company’s manufacturing operations from its 114-megawatt Tyson Nick Solar Project in Lamar County, Texas.

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.

Houston geothermal company picks Nevada site for commercial-scale project

coming soon

Sage Geosystems, a Houston-based developer of geothermal power systems, has chosen a site in Nevada for its commercial-scale Project Vector facility.

The company’s two-well enhanced geothermal system (EGS) will deliver around-the-clock geothermal heat to Ormat Technologies’ Blue Mountain geothermal power plant in Winnemucca, Nevada.

The startup expects to begin drilling the first well later this year, with the first electricity to be generated in 2027 and full-scale production to start in 2028.

In the Nevada system, fluid will circulate through an engineered subsurface reservoir, absorb heat from the surrounding rock and return heat to the surface. The heat will be delivered to the Blue Mountain plant for conversion into electricity.

Project Vector builds on the performance of Sage’s SMECI facility in South Texas. That facility’s results, combined with Sage’s digital twin platform, will be used to shape to the design and development of Project Vector.

Project Vector supports Sage’s growing commercial pipeline, including a 150-megawatt geothermal power agreement with Meta Platforms, the parent company of Facebook and Instagram.

“Blue Mountain is an ideal location for Sage to take the next step in continuing to commercialize our proprietary EGS approach,” Jason Peart, chief operating officer at Sage, said in a release. “By delivering geothermal heat into an existing power plant, Project Vector can demonstrate the model for bringing firm, 24/7 geothermal power to market at scale.”

Project Vector extends Sage’s relationship with Ormat.

In August 2025, Sage and Ormat agreed to accelerate commercialization of Sage’s geothermal technology at an Ormat power plant. This January, Ormat co-led Sage’s $97 million Series B funding round.

Sage, founded in 2020, has raised about $159 million across three funding rounds.

As the startup ramps up its ESG platform, Sage is targeting data centers as customers, among other large-scale users of electricity.

“The energy needs are huge, and they need it now,” CEO Cindy Taff said on Data Center Frontiers’ podcast. “They can’t depend on the grid anymore.”

Houston’s power advantage: Key takeaways from 2026 HETI Power Summit

The view from heti

Power has become a defining economic development issue as electricity demand rises across Texas.

Industrial expansion, advanced manufacturing, AI and data center growth are increasing the importance of reliable, affordable power delivered on the timelines major projects require.

The 2026 HETI Power Summit, titled Houston’s Power Advantage: Competing for Large-Load Growth, brought together leaders from utilities, power producers, large energy customers, technology and infrastructure providers, professional services firms and the public sector to examine how Houston can meet this moment.

Across keynotes, research report-outs, panel discussions and a fireside chat, a consistent theme emerged: Houston’s power advantage comes from the region’s ability to align utilities, customers, infrastructure, flexible demand, emerging solutions and regional partners around reliable, affordable and timely growth.

Reliability and Readiness

Public Utility Commission of Texas Commissioner Kathleen Jackson opened the summit by emphasizing reliability as the foundation for continued growth as Texas electricity demand rises.

Commissioner Jackson underscored the importance of sustained planning and investment to support new industrial, manufacturing and digital demand while maintaining a reliable power system. Remarks framed the morning’s broader discussion of how Houston can pair reliability with speed, affordability and long-term system readiness.

Scott Cockerham of FTI Consulting previewed HETI and FTI’s “Texas Power Market & Industry Assessment”. The research identifies accessibility, reliability, affordability, market flexibility and infrastructure readiness as key dimensions of regional competitiveness.

Leaders from FTI Consulting, Kroll, AWS and Constellation also discussed factors shaping major investment decisions, including reliability, infrastructure timelines, cost certainty, site readiness, community support and regional coordination.

For large customers, these factors must translate into credible project-level execution. Confidence in system performance, energization timelines and infrastructure plans can materially influence major capital commitments.

Building for the Houston We Want to Become

Jason Ryan of CenterPoint Energy challenged participants to plan now for the infrastructure needed to support Houston’s next phase of growth. Drawing on the idea that “what got you here won’t get you there,” Ryan urged the region to build infrastructure for “the Houston we want to become” and stay ahead of large-load demand.

A fireside discussion between CenterPoint Energy and Foxconn brought that challenge to the customer level. The conversation explored how early coordination between utilities and large customers can help advanced manufacturing projects move from site selection and planning to construction and operation.

Long-term growth will require continued investment in generation, transmission and distribution. In the near term, better use of existing infrastructure can create additional capacity.

HETI also shared findings from its Role of Efficiency & Demand Response to Meet Near-Term Regional Power Demand report. Energy efficiency can lower baseline electricity use, while demand response can shift or reduce demand during critical periods. Combined with supply-side investment, these tools can create grid headroom as longer-term infrastructure advances.

The summit’s closing panel, featuring leaders from Amperon, Enchanted Rock, EY and Quanta Services, expanded the discussion to emerging solutions. Panelists explored modular and flexible generation, advanced forecasting, grid intelligence and greater coordination among utilities, customers, infrastructure providers and communities.

Houston’s broader regional power landscape adds another dimension. Entergy Texas President and CEO Eli Viamontes described Southeast Texas as experiencing an “extraordinary trifecta of residential, industrial and data center growth.” His remarks highlighted how the MISO-facing portion of the region complements Houston’s ERCOT strengths through utility planning, generation and infrastructure investment, resource adequacy and coordination with major industrial customers.

Together, these approaches point to a broader strategy: invest for long-term demand while using flexibility, technology and regional coordination to create capacity for growth today.

From Power Advantage to Economic Advantage

Taken together, the Power Summit discussions point to a clear priority for Houston: translating power market and infrastructure strengths into coordinated execution.

Priority areas include earlier infrastructure planning, stronger site and project readiness, clearer pathways from projected demand to reliably served load, expanded efficiency and flexibility, and sustained coordination among utilities, customers, policymakers, communities, technology providers and economic development organizations.

HETI is advancing this work through research and convening efforts focused on Houston’s evolving power needs and economic competitiveness.

The 2026 Power Summit reinforced Houston’s strong foundation for power-intensive growth and the importance of aligning investment, reliability, flexibility and regional coordination around the next generation of economic opportunity.
