The Texas sun keeps rising, as Texas coal wanes.
For the first time ever, solar is set to generate more electricity than coal in the power market managed by the Electric Reliability Council of Texas. Nobody is building new coal power plants in the state, but developers are adding more solar there than anywhere else in the country. As a result of those diverging trajectories, the federal government expects ERCOT will receive 78 billion kilowatt-hours from solar in 2026, and just 60 from coal.
This trend does have seasonal variations. Last year, solar output beat coal on a monthly basis from March through August, and this year it is expected to do so from March through December, per the US Energy Information Administration at the Department of Energy.
Deep-red Texas offers lessons for the liberal states that have committed to lofty climate goals yet failed to build much solar or batteries.
Nationally, the combination of wind and solar surpassed coal generation in 2024, as noted in an analysis by Ember, a think tank that conducts research on clean energy. In other words, the solar industry is further along in Texas than it is nationwide.
The Texas solar surge undercuts the prevailing energy narratives coming out of the Trump administration, which has attempted to boost coal and gas as tools of “energy dominance,” while blocking or canceling American energy that comes from renewables. The Department of Energy, for instance, is keeping struggling coal plants on life support at great expense to taxpayers. Meanwhile, the Department of the Interior is blocking wind and solar developments that intersect with public lands.
Trump officials have argued that coal is more reliable than solar because it can generate power around the clock. But even with that advantage, coal plants in Texas can’t keep up with the total annual and monthly production from the rapidly growing solar fleet. This has not damaged grid reliability, because ERCOT meets evening demand with a diverse portfolio, including gas plants, nuclear, wind, and, increasingly, batteries, which store all that excess solar power for use when the sun stops shining.
Of course, Texas leaders did not set out to disprove the Trump administration’s energy claims. The maverick Lone Star State kept its electricity system out of the hands of federal regulators, and in the 1990s and early 2000s reformed it to promote free market competition instead of centralized planning by monopoly utilities. That market, coupled with lots of space and lax building regulations, has made an ideal environment for wind, solar, and batteries to flourish. Now, Texas is fortified with tens of gigawatts of new capacity with which to tackle heat waves and temper price spikes.
Deep-red Texas offers lessons for the liberal states that have committed to lofty climate goals yet failed to build much solar or batteries so far. They can’t immediately switch over to an ERCOT-style market, but they can take steps to speed up the time it takes to get permits and grid connection, dial back the level of deference to habitually conservative legacy utilities, and make sure that clean energy gets a fair shot in the race to serve surging energy needs. And it’s always a good time to reexamine old market rules that subtly privilege entrenched players at the expense of new entrants that would make cheaper and cleaner power.
After more of the rapid-fire solar buildout, EIA expects ERCOT will produce 99 billion kilowatt-hours of solar power in 2027, up 27% from 2026. At that point, the upstart industry will have left its well-established coal competition in the dust.
