Although the first official day of summer is not until June 20, Houstonians are already feeling the heat with record-breaking, triple-digit temperatures. The recent heatwave has many Texans wondering if the state’s grid will have enough power to meet peak demand during the summer.

How the Texas grid fared in summer 2024

To predict what could happen as we enter summer this year, it is essential to assess the state of the grid during summer 2024, and what, if anything, has been improved.

According to research from the Federal Reserve Bank of Dallas, solar electricity generation and utility-scale batteries within the ERCOT power grid set records in summer 2024. On average, solar contributed nearly 25 percent of total power needs during mid-day hours between June 1 and August 31. In critical evening hours, when load (demand for electricity) remains elevated but solar output declines, discharge from batteries successfully filled the gap.

Texas added more battery storage capacity than any other state last year, and, excluding California, now has more battery capacity than the rest of the country combined. The state also added 3,410 megawatts of natural gas-fueled power last year. While we did experience major power losses as a result of extreme weather, such as the derecho in May and Hurricane Beryl in July, ERCOT did not have to issue a single conservation appeal last summer to ward off capacity-related outages--and it was the sixth-hottest summer on record.

Policymakers are also taking steps to pass legislation that will help stabilize the grid. During this year’s 89th legislative session, Senate Bill 6 (TX SB6) was introduced, which seeks to:

  • Improve ERCOT's load forecasting transparency
  • Enhance outage protections for residential consumers
  • Adjust transmission cost allocations
  • Bolster grid reliability

In essence, the bill is meant to balance business growth with grid reliability, ensuring that the state continues to be an attractive destination for industrial expansion while preventing reliability risks due to rapid demand increases.

Is the Texas grid prepared for summer 2025?

The good news is that the grid is predicted to be able to manage the energy demand this summer, but there is no guarantee that power disruptions will not happen.

The National Oceanic and Atmospheric Administration has indicated that summer 2025 will likely be warmer and drier than average across most of Texas. Based on ERCOT data and weather projections, West Texas and the Dallas-Fort Worth and Houston metropolitan areas face the highest risk of outages.

While Texas is No. 1 in wind power and No. 2 in solar power, only behind California, there are valid concerns about heavy reliance on renewables when the wind isn’t blowing or the sun isn’t shining, compounded by a lack of large-scale battery storage. Then, there’s the underlying cost and ecological footprint associated with the manufacturing of those batteries. Although solar and wind capacity continues to expand rapidly, integration challenges remain during peak demand periods, especially during the late afternoon when solar generation declines but air conditioning usage remains high.

Additional factors that contribute to the grid’s instability are that Texas faces a massive surge in demand for electricity due to an increase in large users like crypto mining facilities and data centers, as well as population growth. ERCOT predicts that Texas’ energy demand will nearly double by 2030, with power supply projected to fall short of peak demand in a worst-case scenario beginning in summer 2026.

Thanks to investments in solar power, battery storage, and traditional energy sources, ERCOT has made progress in improving grid reliability which indicates that, at least for this summer, energy load will be manageable. A combination of legislative action, strategic planning and technological innovation will need to continue to ensure that this momentum remains on a positive trajectory.

Texans are facing extreme weather at every turn — can the grid withstand these events? Photo via heimdallpower.com

Can the Texas grid handle extreme weather conditions across regions?

Guest Column

From raging wildfires to dangerous dust storms and fierce tornadoes, Texans are facing extreme weather conditions at every turn across the state. Recently, thousands in the Texas Panhandle-South Plains lost power as strong winds ranging from 35 to 45 mph with gusts upwards of 65 mph blew through. Meanwhile, many North Texas communities are still reeling from tornadoes, thunderstorms, and damaging winds that occurred earlier this month.

A report from the National Oceanic and Atmospheric Administration found that Texas led the nation with the most billion-dollar weather and climate disasters in 2023, while a report from Texas A&M University researchers indicates Texas will experience twice as many 100-degree days, 30-50% more urban flooding and more intense droughts 15 years from now if present climate trends persist.

With the extreme weather conditions increasing in Texas and nationally, recovering from these disasters will only become harder and costlier. When it comes to examining the grid’s capacity to withstand these volatile changes, we’re past due. As of now, the grid likely isn’t resilient enough to make do, but there is hope.

Where does the grid stand now?

Investment from utility companies have resulted in significant improvements, but ongoing challenges remain, especially as extreme weather events become more frequent. While the immediate fixes have helped improve reliability for the time being, it won't be enough to withstand continuous extreme weather events. Grid resiliency will require ongoing efforts over one-time bandaid approaches.

What can be done?

Transmission and distribution infrastructure improvements must vary geographically because each region of Texas faces a different set of hazards. This makes a one-size-fits-all solution impossible. We’re already seeing planning and investment in various regions, but sweeping action needs to happen responsibly and quickly to protect our power needs.

After investigators determined that the 2024 Smokehouse Creek fire (the largest wildfire in Texas history) was caused by a decayed utility pole breaking, it raised the question of whether the Panhandle should invest more in wrapping poles with fire retardant material or covering wires so they are less likely to spark.

In response, Xcel Energy (the Panhandle’s version of CenterPoint) filed its initial System Resiliency Plan with the Public Utility Commission of Texas, with proposed investments to upgrade and strengthen the electric grid and ensure electricity for about 280,000 homes and businesses in Texas. Tailored to the needs of the Texas Panhandle and South Plains, the $539 million resiliency plan will upgrade equipment’s fire resistance to better stand up to extreme weather and wildfires.

Oncor, whose territories include Dallas-Fort Worth and Midland-Odessa, analyzed more than two decades of weather damage data and the impact on customers to identify the priorities and investments needed across its service area. In response, it proposed investing nearly $3 billion to harden poles, replace old cables, install underground wires, and expand the company's vegetation management program.

What about Houston?

While installing underground wires in a city like Dallas makes for a good investment in grid resiliency, this is not a practical option in the more flood-prone areas of Southeast Texas like Houston. Burying power lines is incredibly expensive, and extended exposure to water from flood surges can still cause damage. Flood surges are also likely to seriously damage substations and transformers. When those components fail, there’s no power to run through the lines, buried or otherwise.

As part of its resiliency plan for the Houston metro area, CenterPoint Energy plans to invest $5.75 billion to strengthen the power grid against extreme weather. It represents the largest single grid resiliency investment in CenterPoint’s history and is currently the most expensive resiliency plan filed by a Texas electric utility. The proposal calls for wooden transmission structures to be replaced with steel or concrete. It aims to replace or strengthen 5,000 wooden distribution poles per year until 2027.

While some of our neighboring regions focus on fire resistance, others must invest heavily in strengthening power lines and replacing wooden poles. These solutions aim to address the same critical and urgent goal: creating a resilient grid that is capable of withstanding the increasingly frequent and severe weather events that Texans are facing.

The immediate problem at hand? These solutions take time, meaning we’re likely to encounter further grid instability in the near future.

How has the Texas grid improved since Winter Storm Uri in 2021? Getty Images

Being prepared: Has the Texas grid been adequately winterized?

Winter in Texas

Houstonians may feel anxious as the city and state brace for additional freezing temperatures this winter. Every year since 2021’s Winter Storm Uri, Texans wonder whether the grid will keep them safe in the face of another winter weather event. The record-breaking cold temperatures of Uri exposed a crucial vulnerability in the state’s power and water infrastructure.

According to ERCOT’s 6-day supply and demand forecast from January 3, 2025, it expected plenty of generation capacity to meet the needs of Texans during the most recent period of colder weather. So why did the grid fail so spectacularly in 2021?

  1. Demand for electricity surged as millions of people tried to heat their homes.
  2. ERCOT was simply not prepared despite previous winter storms of similar intensity to offer lessons in similarities.
  3. The state was highly dependent on un-winterized natural gas power plants for electricity.
  4. The Texas grid is isolated from other states.
  5. Failures of communication and coordination between ERCOT, state officials, utility companies, gas suppliers, electricity providers, and power plants contributed to the devastating outages.

The domino effect resulted in power outages for millions of Texans, the deaths of hundreds of Texans, billions of dollars in damages, with some households going nearly a week without heat, power, and water. This catastrophe highlighted the need for swift and sweeping upgrades and protections against future extreme weather events.

Texas State Legislature Responds

Texas lawmakers proactively introduced and passed legislation aimed at upgrading the state’s power infrastructure and preventing repeated failures within weeks of the storm. Senate Bill 3 (SB3) measures included:

  • Requirements to weatherize gas supply chain and pipeline facilities that sell electric energy within ERCOT.
  • The ability to impose penalties of up to $1 million for violation of these requirements.
  • Requirement for ERCOT to procure new power sources to ensure grid reliability during extreme heat and extreme cold.
  • Designation of specific natural gas facilities that are critical for power delivery during energy emergencies.
  • Development of an alert system that is to be activated when supply may not be able to meet demand.
  • Requirement for the Public Utility Commission of Texas, or PUCT, to establish an emergency wholesale electricity pricing program.

Texas Weatherization by Natural Gas Plants

In a Railroad Commission of Texas document published May 2024 and geared to gas supply chain and pipeline facilities, dozens of solutions were outlined with weatherization best practices and approaches in an effort to prevent another climate-affected crisis from severe winter weather.

Some solutions included:

  • Installation of insulation on critical components of a facility.
  • Construction of permanent or temporary windbreaks, housing, or barriers around critical equipment to reduce the impact of windchill.
  • Guidelines for the removal of ice and snow from critical equipment.
  • Instructions for the use of temporary heat systems on localized freezing problems like heating blankets, catalytic heaters, or fuel line heaters.

According to Daniel Cohan, professor of environmental engineering at Rice University, power plants across Texas have installed hundreds of millions of dollars worth of weatherization upgrades to their facilities. In ERCOT’s January 2022 winterization report, it stated that 321 out of 324 electricity generation units and transmission facilities fully passed the new regulations.

Is the Texas Grid Adequately Winterized?

Utilities, power generators, ERCOT, and the PUCT have all made changes to their operations and facilities since 2021 to be better prepared for extreme winter weather. Are these changes enough? Has the Texas grid officially been winterized?

This season, as winter weather tests Texans, residents may potentially experience localized outages. When tree branches cannot support the weight of the ice, they can snap and knock out power lines to neighborhoods across the state. In the instance of a downed power line, we must rely on regional utilities to act quickly to restore power.

The specific legislation enacted by the Texas state government in response to the 2021 disaster addressed to the relevant parties ensures that they have done their part to winterize the Texas grid.

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.

Houston geothermal companies secure more than $45M in DOE funding

geothermal boost

Three Houston-based companies—Fervo Energy, Quaise Energy and XGS Energy—have been selected by the U.S. Department of Energy to advance geothermal technologies and field tests.

Combined, the companies will receive more than $45 million in funding from the DOE's Next-Generation Geothermal Field Tests and Geothermal Resource Characterization and Confirmation initiative. The projects were among 21 selected from around the country to receive a total of $99 million.

Fervo was selected to conduct two projects under the initiative for approximately $20 million in funding. For the first project, the geothermal unicorn, which achieved first power at its flagship geothermal plant last week, will drill and complete enhanced geothermal systems (EGS) wells in Elmore County, Idaho, and will deploy high-temperature seismic monitoring technology at record-high temperatures at or above 200°C.

For the second project, the company will conduct an appraisal drilling campaign at a "high-priority" site in Humboldt County, Nevada, to confirm if the reservoir is suitable for EGS development.

“We are grateful to the Department of Energy for funding these grants. We believe this is a clear indication from the federal government that expanding geothermal energy to new states is a national priority,” Jack Norbeck, CTO and co-founder of Fervo Energy, said in a news release. “We expect this funding to accelerate Fervo’s pipeline and advance the cutting edge of geothermal technologies.”

Fresh off a $180 million Series B, Quaise Energy also received $25 million in DOE funding through the initiative to support its Project Obsidian super hot geothermal plant in Central Oregon. The funding will go toward the analysis of the drilling, stimulation and flow results of the first two wells at the Project Obsidian site, which will help the company optimize its third well on site.

“This DOE support is a recognition of what we are building at Quaise and the progress we are making in the field, including the confirmation well currently being drilled at Project Obsidian,” Carlos Araque, CEO and president of Quaise, said in a release. “Our ambition has always been to make superhot geothermal a commercial reality, and Project Obsidian is where we first deliver on that promise.”

XGS Energy, which recently relocated its headquarters from Palo Alto, California, to Houston, was also selected for an exploration drilling project. The company will drill a deep vertical appraisal well in Socorro County, New Mexico, to determine if the site is a viable source of geothermal energy. XGS had not disclosed a funding estimate at press time.

The full value of the proposed DOE funding is subject to completion of award negotiations, according to Quaise.

Data from these projects will be shared through DOE’s Geothermal Data Repository (GDR), providing valuable information to researchers and stakeholders in the geothermal sector.

“This is an excellent example of how public and private entities can partner together to scale critical energy technologies,” Tim Latimer, CEO and co-founder of Fervo, added in a release. “With this funding, the Department of Energy is making important investments to help Americans across the country gain access to clean, affordable geothermal energy.”

Other geothermal companies and institutions from around the country will complete the 17 remaining projects. They include:

  • Denver-based 400C Energy Inc.
