Texas Renewable Energy Generation

Texas: An Unexpected Renewable Powerhouse

Texas might be famous for oil and gas, but it is also the undisputed leader in US wind energy and one of the fastest-growing solar markets in the country. The state’s massive open spaces, strong wind corridors, and abundant sunshine make it ideal for renewable generation at scale.

Wind Energy in Texas

Texas has more installed wind capacity than any other state, with over 40,000 megawatts as of 2025. To put that in perspective, that is more than the next three states combined (Iowa, Oklahoma, and Kansas).

Most of Texas’s wind farms are in West Texas and the Panhandle, where steady winds blow across flat terrain. The Gulf Coast also has growing wind capacity. Major wind corridors include:

• The Panhandle and South Plains — Consistently strong winds and minimal development conflicts
• West Texas — The Permian Basin area has both oil wells and wind turbines
• The Gulf Coast corridor — Coastal winds that pick up in spring and summer
• Central Texas — The area between Abilene and the Hill Country

Wind generation in Texas peaks during spring nights, when strong frontal systems push through the state. It is not unusual for wind to supply 50% or more of ERCOT’s electricity during a breezy March night. Wind output is typically lower during hot summer afternoons, which is why solar has become an important complement.

Solar Energy in Texas

Solar has been the fastest-growing generation source in Texas over the past several years. Installed solar capacity in ERCOT has grown from under 5,000 megawatts in 2020 to over 25,000 megawatts in 2025, and new projects continue to come online.

Most utility-scale solar farms are in West Texas, South Texas, and the Panhandle, where sunshine is abundant and land is inexpensive. Solar generation peaks during midday hours and drops to zero at night, which creates the characteristic “duck curve” — a demand pattern where net demand (total demand minus solar output) dips during the day and rises sharply in the evening.

Solar’s growth has noticeably pushed down wholesale electricity prices during midday hours. On sunny spring days, wholesale prices occasionally go negative, meaning generators are essentially paying the grid to take their electricity.

How Renewables Fit Into the Grid

Wind and solar are intermittent — they produce electricity when conditions are right, not necessarily when demand is highest. Managing this variability is one of ERCOT’s key challenges:

Battery storage is growing rapidly in Texas. Utility-scale batteries can absorb excess solar and wind energy during production peaks and release it during evening demand peaks. As of 2025, Texas has over 5,000 megawatts of installed battery storage, with much more under development.

Natural gas backup remains essential. When wind dies down and the sun sets, natural gas plants ramp up to fill the gap. Texas has over 70,000 megawatts of natural gas capacity, making it the backbone of the grid during low-renewable periods.

The CREZ transmission lines were a game-changer. Completed in 2014, the Competitive Renewable Energy Zones (CREZ) project built 3,600 miles of high-voltage transmission lines to carry wind energy from West Texas to the population centers in Dallas, Houston, San Antonio, and Austin. Without CREZ, much of Texas’s wind capacity would be stranded.

What This Means for Electricity Prices

Renewable energy has put meaningful downward pressure on wholesale electricity prices in Texas. Wind and solar have near-zero fuel costs — once a turbine or solar panel is built, the electricity it produces is extremely cheap. This displaces more expensive natural gas generation and brings down the market clearing price.

The effect is most visible during:

• Spring and fall — Mild temperatures reduce demand while wind production is strong
• Midday hours — Solar output peaks, flooding the market with cheap energy
• Overnight hours — Wind production is often high while demand is at its lowest

For retail customers, this has contributed to competitive fixed rates and has made 100% renewable plans more affordable than ever.

Choosing a Renewable Plan

Many REPs offer plans marketed as 100% renewable. These plans are backed by Renewable Energy Certificates (RECs), which are tradable certificates proving that a megawatt-hour of electricity was generated from a qualifying renewable source.

When you sign up for a 100% renewable plan:

• Your physical electricity still comes from the same grid as everyone else
• Your REP purchases or retires RECs equal to your consumption
• The environmental benefit is real — your dollars support renewable generation

Renewable plans are not always more expensive. Some 100% renewable plans are priced the same as or lower than conventional plans, depending on market conditions and how the REP sources its RECs.

The Bottom Line

Texas is one of the largest renewable energy producers in the world, with wind and solar together generating roughly 40% of the state’s electricity. This growth has pushed down wholesale prices, created new plan options for consumers, and reduced the grid’s carbon footprint. The ongoing challenge is building enough storage and backup generation to maintain reliability as renewable penetration continues to grow.
