Texas has long been associated with oil, natural gas and wind power.
But in 2026, another energy source is expanding at remarkable speed:
solar power.
As of June 2026, Texas had about 32.7 GW of utility-scale solar capacity, up from roughly 24.9 GW one year earlier. Including smaller solar systems, total photovoltaic capacity reached approximately 36 GW.
The growth is large enough that the U.S. Energy Information Administration expects utility-scale solar generation in ERCOT to surpass coal generation for the first time in 2026.
So why is Texas adding solar faster than almost anywhere else in the United States?
The answer is not simply that Texas gets a lot of sunshine.
It is the combination of strong solar resources, rapidly rising electricity demand, large-scale development, battery storage and the changing economics of the Texas power grid.
1. Texas Has Excellent Conditions for Utility-Scale Solar
The first reason is straightforward.
Texas has large areas with strong solar resources and enough available land to build enormous solar projects.
This matters because the current Texas solar boom is primarily a utility-scale power generation story, not just a rooftop solar story.
According to EIA data, more than 90% of Texas solar capacity in June 2026 came from utility-scale facilities rather than small residential and commercial systems.
That makes it possible for developers to build projects measured in hundreds of megawatts instead of installing panels one house at a time.
Texas has already overtaken California in utility-scale solar capacity, even though California still has more total solar capacity when its much larger rooftop market is included.
2. Electricity Demand in Texas Is Growing Quickly
Solar is also expanding because Texas simply needs more electricity.
ERCOT recorded a new all-time hourly electricity demand record of 91.1 GW on July 22, 2026.
That was about 6% above the previous record set in 2023.
What makes this especially interesting is when the peak occurred.
At approximately 6 p.m., solar was still supplying about 32% of ERCOT generation, while natural gas supplied around 48%.
Texas has a growing population, large industrial loads, air-conditioning demand and rapidly expanding data-center development.
All of those loads require electricity.
Solar cannot supply every hour of that demand, but during hot summer afternoons it can provide a large amount of generation precisely when the grid is heavily loaded.

3. Texas Is Building an Enormous Share of New U.S. Solar
The scale of planned construction is another major reason Texas stands out.
The EIA reported that U.S. developers planned to add approximately 43.4 GW of utility-scale solar capacity during 2026.
Around 40% of those planned additions are in Texas.
That means roughly 17 GW of the country’s planned utility-scale solar additions are concentrated in a single state if all reported projects are completed.
One example is the Tehuacana Creek 1 Solar and BESS project.
The project is expected to include about 837 MW of solar capacity combined with approximately 418 MW of battery storage, making it one of the largest solar projects scheduled to enter service in 2026.
This is no longer incremental growth.
Texas is building solar at power-plant scale.
4. Solar Is Starting to Replace More Midday Fossil Generation
As more solar enters ERCOT, it changes the shape of electricity generation during the day.
Solar production becomes strongest during daylight hours, reducing the amount of electricity that needs to be supplied by other generators at the same time.
EIA data shows how quickly that shift has occurred.
Solar accounted for only about 4% of ERCOT generation in 2021, but its share had increased to approximately 12% by 2025.
For 2026, EIA expects utility-scale solar generation to reach around 78 billion kWh, compared with approximately 60 billion kWh from coal.
If that forecast holds, 2026 will be the first year solar generates more electricity than coal across ERCOT.
Natural gas will still remain extremely important.
But solar is becoming a much larger part of the Texas generation mix.
5. Battery Storage Is Making More Solar Useful
There is one obvious weakness with solar:
The sun goes down.
Texas electricity demand, however, does not disappear at sunset.
Air conditioners, businesses, homes and data centers can continue consuming large amounts of electricity into the evening.
That creates what I think is one of the most important parts of the Texas energy story:
solar and battery storage are now expanding together.
Developers planned approximately 12.9 GW of new utility-scale battery capacity in Texas during 2026, more than half of all planned U.S. battery additions for the year.
A battery can charge when solar production is high and release some of that energy later as solar generation declines.
It does not make solar available all night, and it does not replace the need for reliable generation or transmission.
But it makes a grid with large amounts of solar significantly more flexible.
👉 This connection between solar and storage is becoming increasingly important. See [Why Is Battery Energy Storage Growing So Fast in the U.S.?]
6. Solar Can Be Added Faster Than Many Large Power Projects
There is also a practical infrastructure advantage.
A utility-scale solar project consists of large numbers of repeatable components: modules, inverters, transformers, cables, switchgear and supporting structures.
Once land, permits, equipment and grid interconnection are available, solar capacity can be expanded using a relatively modular construction process.
That matters in a state where electricity demand is increasing quickly.
A large transmission project or conventional power station can require many years of planning and construction.
Solar is not free from delays — especially when transmission capacity or interconnection becomes constrained — but developers can build large amounts of generating capacity comparatively quickly.
That helps explain why so much of America’s near-term generation pipeline now consists of solar projects.
My View From the Electrical Construction Side
From an electrical construction perspective, I think the most interesting part of the Texas solar boom is what exists behind the panels.
A 500 MW or 800 MW solar project is not simply a large field filled with photovoltaic modules.
It also requires:
inverters, transformers, switchgear, protection systems, high-voltage substations, underground and overhead cables, monitoring systems and grid interconnection infrastructure.
Add battery storage and the electrical system becomes even more complex.
This is why I view Texas solar growth as more than a renewable-energy trend.
It is also a massive electrical infrastructure buildout.
And as generation grows, transmission capacity becomes increasingly important.
Building solar power is only useful if the grid can actually move that electricity from where it is generated to where people and businesses need it.
Is Texas Solar Growth Likely to Continue?
For now, the pipeline suggests that solar growth has not finished.
EIA expects ERCOT solar generation to rise from roughly 56 billion kWh in 2025 to 106 billion kWh by 2027.
But that does not mean solar can grow without limits.
Transmission congestion, interconnection delays, periods of excess midday generation and the evening decline in solar output all become more important as capacity increases.
That is why batteries, transmission upgrades and flexible generation will matter alongside solar.
The real Texas energy story is therefore not:
solar versus natural gas.
It is how Texas combines solar, natural gas, batteries, wind and grid infrastructure to supply a rapidly growing electricity system.
Final Thoughts
Solar is growing so fast in Texas because several conditions have aligned at the same time.
Texas has strong solar resources and space for very large projects.
Electricity demand is setting records.
Developers are building a huge share of America’s new solar capacity in the state.
And rapidly expanding battery storage is making daytime solar generation more useful during evening hours.
The result is one of the fastest electricity-generation transformations in the United States.
Texas may still be famous for oil and natural gas.
But when it comes to building new electricity generation in 2026, solar has become one of the state’s biggest energy stories.
