The Texas electric grid is currently operating at the intersection of a historic energy transition and an unprecedented surge in demand. As the state moves toward its bicentennial in 2036, the challenge of powering one of the fastest-growing economies in the world has shifted from a question of simply “adding power” to one of fundamental structural evolution.
In the latest episode of the Future of Texas podcast series, ERCOT President and CEO Pablo Vegas joined Jeremy Mazur, Senior Policy Advisor at Texas 2036, to dissect the state’s energy roadmap. Their discussion reveals a grid that is being tested by new technologies—from artificial intelligence data centers to massive battery storage—while operating under a regulatory and market framework that must evolve as fast as the demand it serves.
For years, the “Texas Miracle” has been fueled by a reliable influx of people and businesses. However, the nature of that growth has changed. “Texas remains one of the country’s fastest growing large states,” Vegas notes, but he emphasizes that we are now adding “energy intensive industries” at a rate rarely seen in mature power markets.
The numbers are staggering. ERCOT recently released preliminary long-term forecasts projecting that peak demand could triple or even quadruple by 2032, reaching approximately 367,790 megawatts (MW).
For context, the state’s all-time record peak demand was 85,508 MW, set in August 2023. While Vegas cautions that this forecast is a “preliminary snapshot” and believes it may be “higher than expected future load growth,” the trend is clear: Texas is entering an era of “exceptional growth and development”.
This surge is driven by a “convergence of three things,” according to industry analysts: artificial intelligence data centers, cryptocurrency mining, and hydrogen electrolysis. Vegas told lawmakers that his agency is tracking connection requests that could require 410,000 MW of power, with data centers accounting for 87% of that total.
As demand climbs, the “composition of the resource fleet” is changing. Between 2021 and 2025, Texas synchronized approximately 62,000 MW of new generation to the grid. However, the vast majority of this—roughly 31,000 MW of solar and 10,000 MW of wind—is intermittent.
“Solar and battery resources provide important reliability benefits,” Vegas explains, but “their variability and limited duration increase reliance on dispatchable generation during certain critical demand periods”.
The risk is compounded by an aging thermal fleet; currently, 42% of the natural gas and coal plants in ERCOT are more than 30 years old. The challenge for policymakers is ensuring these “critical, dispatchable resources” are replaced.
Mazur and the Texas 2036 team have highlighted that while lower wholesale electricity prices are good for the economy, they “support concerns that Texas’ electric market will not be attractive enough for future capital investment in dispatchable forms of generation”.
Innovation isn’t just happening on the demand side; it is also the grid’s primary hope for maintaining stability. Texas is currently home to the fastest-growing utility-scale solar market in the country, and battery capacity is expected to more than double from 15 GW in 2025 to 37 GW by the end of 2027.
One of the most exciting frontiers discussed is the “Virtual Power Plant” (VPP) pilot program. “We have this potential to not only think about resources through the big power plants… but also in the resources that are across millions and millions of homes,” Vegas says.
These programs allow millions of small devices—like home batteries and smart thermostats—to be tapped into as a collective resource during peak times to “help with both the reliability, the resiliency, and the economics of the market in the future”.
Vegas notes that the technology exists today to turn every Texas home into a potential contributor to grid stability. “We are seeing that it actually works,” he says of the pilot scales, though he adds that the state still needs to “put in place some of the rules around that”.
To move this power to where it’s needed, Texas must also solve a “build-speed” problem with transmission. The electrification of oil and gas operations in the Permian Basin is a primary driver for new transmission capacity.
Mazur emphasizes that keeping up with growth “isn’t just about adding more power. It’s about building a system that can operate at scale, under pressure and over time”. This includes leveraging innovations like “Grid Enhancing Technologies” (GETs), such as dynamic line ratings, to maximize the capacity of existing lines.
As 2036 approaches, the success of the Texas grid will be measured by its ability to remain both reliable and affordable. Currently, Texas 2036 models project a “near doubling of electric demand” by 2050 across all scenarios. Residential cooling demand alone is expected to increase by as much as 74% as the state climatologist predicts an increase in 100-degree days.
The legislative response has already begun. The passage of Senate Bill 6 in 2025 signals a shift toward finding ways to “allocate costs to those that consume the most power,” such as data centers and crypto miners, which could lead to “lower electricity bills for small users”.
“Texas is experiencing exceptional growth,” Vegas concludes, but that growth is “reshaping how large load demand is identified, verified, and incorporated into long-term planning”. For the leaders tasked with keeping the lights on, the mission is clear: the “Texas Miracle” can only continue if the state builds a grid that is as innovative as the industries it powers.
