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.

Rice University partners with Australian co. to boost mineral processing, battery innovation

critical mineral partnership

Rice University and Australian mineral exploration company Locksley Resources have joined together in a research partnership to accelerate the development of antimony processing in the U.S. Antimony is a critical mineral used for defense systems, electronics and battery storage.

Rice and Locksley will work together to develop scalable methods for extracting and utilizing antimony. Currently, the U.S. relies on imports for nearly all refined antimony, according to Rice.

Locksley will fund the research and provide antimony-rich feedstocks and rare earth elements from a project in the Mojave Desert. The research will explore less invasive hydrometallurgical techniques for antimony extraction and explore antimony-based materials for use in batteries and other energy storage applications.

“This strategic collaboration with Rice marks a pivotal step in executing Locksley’s U.S. strategy,” Nathan Lude, chairman of Locksley Resources, said in a news release. “By fast-tracking our research program, we are helping rebuild downstream capacity through materials innovation that the country urgently requires.”

Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Materials Science and Nanoengineering at Rice, is the principal investigator of the project.

“Developing scalable, domestic pathways for antimony processing is not only a scientific and engineering challenge but also a national strategic priority,” Ajayan said in the news release. “By combining Rice’s expertise in advanced materials with Locksley’s resources, we can address a critical supply chain gap and build collaborations that strengthen U.S. energy resilience.”

The Rice Advanced Materials Institute (RAMI) will play a major role in supporting the advancement of technology and energy-storage applications.

“This partnership aligns with our mission to lead in materials innovations that address national priorities,” Lane Martin, director of RAMI, said in a news release. “By working with Locksley, we are helping to build a robust domestic supply chain for critical materials and support the advancement of next-generation energy technologies.”

Expert examines how far Texas has come in energy efficiency

Guest Column

Texas leads the nation in energy production, providing about one-fourth of the country’s domestically produced primary energy. It is also the largest energy-consuming state, accounting for about one-seventh of the nation’s total energy use, and ranks sixth among the states in per capita energy consumption.

However, because Texas produces significantly more energy than it consumes, it stands as the nation’s largest net energy supplier. October marked National Energy Awareness Month, so this is an ideal time to reflect on how far Texas has come in improving energy efficiency.

Progress in Clean Energy and Grid Resilience

Texas continues to lead the nation in clean energy adoption and grid modernization, particularly in wind and solar power. With over 39,000 MW of wind capacity, Texas ranks first in the country in wind-powered electricity generation, now supplying more than 10% of the state’s total electricity.

This growth was significantly driven by the Renewable Portfolio Standard (RPS), which requires utility companies to produce new renewable energy in proportion to their market share. Initially, the RPS aimed to generate 10,000 MW of renewable energy capacity by 2025. Thanks to aggressive capacity building, this ambitious target was reached much earlier than anticipated.

Solar energy is also expanding rapidly, with Texas reaching 16 GW of solar capacity as of April 2024. The state has invested heavily in large-scale solar farms and supportive policies, contributing to a cleaner energy mix.

Texas is working to integrate both wind and solar to create a more resilient and cost-effective grid. Efforts to strengthen the grid also include regulatory changes, winterization mandates, and the deployment of renewable storage solutions.

While progress is evident, experts stress the need for continued improvements to ensure grid reliability during extreme weather events, when we can’t rely on the necessities for these types of energy sources to thrive. To put it simply, the sun doesn’t always shine, and the wind doesn’t always blow.

Federal Funding Boosts Energy Efficiency

In 2024, Texas received $22.4 million, the largest share of a $66 million federal award, from the U.S. Department of Energy’s Energy Efficiency Revolving Loan Fund Capitalization Grant Program.

The goal of this funding is to channel federal dollars into local communities to support energy-efficiency projects through state-based loans and grants. According to the DOE, these funds can be used by local businesses, homeowners, and public institutions for energy audits, upgrades, and retrofits that reduce energy consumption.

The award will help establish a new Texas-based revolving loan fund modeled after the state’s existing LoanSTAR program, which already supports cost-effective energy retrofits for public facilities and municipalities. According to the Texas Comptroller, as of 2023, the LoanSTAR program had awarded more than 337 loans totaling over $600 million.

In addition to expanding the revolving loan model, the state plans to use a portion of the DOE funds to offer free energy audit services to the public. The grant program is currently under development.

Building on this momentum, in early 2025, Texas secured an additional $689 million in federal funding to implement the Home Energy Performance-Based, Whole House (HOMES) rebate program and the Home Electrification and Application Rebate (HEAR) program.

This investment is more than five times the state’s usual energy efficiency spending. Texas’s eight private Transmission and Distribution Utilities typically spend about $110 million annually on such measures. The state will have multiple years to roll out both the revolving loan and rebate programs.

However, valuable federal tax incentives for energy-efficient home improvements are set to expire on December 31, 2025, including:

  • The Energy Efficiency Home Improvement Credit allows homeowners to claim up to $3,200 per year in federal income tax credits, covering 30% of the cost of eligible upgrades, such as insulation, windows, doors, and high-efficiency heating and cooling systems.
  • The Residential Clean Energy Credit provides a 30% income tax credit for the installation of qualifying clean energy systems, including rooftop solar panels, wind turbines, geothermal heat pumps, and battery storage systems.

As these incentives wind down, the urgency grows for Texas to build on the positive gains from the past several years despite reduced federal funding. The state has already made remarkable strides in clean energy production, grid modernization, and energy-efficiency investments, but the path forward requires a strategic and inclusive approach to energy planning. Through ongoing state-federal collaboration, community-driven initiatives, and forward-looking policy reforms, Texas can continue its progress, ensuring that future energy challenges are met with sustainable and resilient solutions.

Meta to buy all power from new ENGIE Texas solar farm

power purchase

Meta, the parent company of social media platform Facebook, has agreed to buy all of the power from a $900 million solar farm being developed near Abilene by Houston-based energy company ENGIE North America.

The 600-megawatt Swenson Ranch solar farm, located in Stonewall County, will be the largest one ever built in the U.S. by ENGIE. The solar farm is expected to go online in 2027.

Meta will use electricity generated by the solar farm to power its U.S. data centers. All told, Meta has agreed to purchase more than 1.3 gigawatts of renewable energy from four ENGIE projects in Texas.

“This project marks an important step forward in the partnership between our two companies and their shared desire to promote a sustainable and competitive energy model,” Paulo Almirante, ENGIE’s senior executive vice president of renewable and flexible power, said in a news release.

In September, ENGIE North America said it would collaborate with Prometheus Hyperscale, a developer of sustainable liquid-cooled data centers, to build data centers at ENGIE-owned renewable energy and battery storage facilities along the I-35 corridor in Texas. The corridor includes Austin, Dallas-Fort Worth, San Antonio and Waco.

The first projects under the ENGIE-Prometheus umbrella are expected to go online in 2026.

ENGIE and Prometheus said their partnership “brings together ENGIE's deep expertise in renewables, batteries, and energy management and Prometheus' highly efficient liquid-cooled data center design to meet the growing demand for reliable, sustainable compute capacity — particularly for AI and other high-performance workloads.”
