Texas produces more wind power than any other state in the U.S., accounting for nearly 30% of the electricity generated within the ERCOT system. By 2025, the Lone Star State’s installed wind capacity has surpassed 42 gigawatts, powered by more than 19,000 turbines spread across West Texas, the Panhandle, and South Texas.

The largest wind farms in Texas include Great Prairie Wind, Los Vientos, Roscoe Wind Farm, Horse Hollow Energy Center, and Capricorn Ridge Wind Farm, which was one of the largest wind farms in the world at the time of completion. These large-scale projects collectively power more than one million homes in Texas.

In this article, we will explore the Top 7 Largest Wind Farm Projects in Texas as of 2025. It highlights their scale, output, and contribution to the state’s renewable energy goals.

List of Top 7 Biggest Wind Farm Projects in Texas, United States (according to capacity)

Great Prairie Wind Farm: Largest wind farm in Texas

The Great Prairie Wind project in Hansford County, Texas, stands as the largest wind farm in the state and one of the largest wind farms in the United States for annual electricity generation. Operated by NextEra Energy Resources, the project began commercial operations in November 2022 after being developed in three phases.

The wind farm consists of 365 GE 2.82-127 turbines, each with a 292-foot hub height. Together, they generate about 4.1 terawatt-hours of electricity each year. During the three-month period from April to July 2025, the facility produced 995.8 gigawatt-hours. Electricity from Great Prairie Wind is sold to Amazon Web Services under a long-term power purchase agreement.

Los Vientos Wind Farm

Located in Starr County, South Texas, Los Vientos is the region’s largest wind energy project and one of the state’s earliest large-scale developments outside the Panhandle. Operated by Duke Energy Renewables, the 912-megawatt facility became fully operational in August 2016 after being built in five phases.

The project includes more than 400 turbines and generates enough electricity to power about 120,000 homes. Power from Los Vientos is delivered to several Texas cities, including Garland, Greenville, and Bryan, and even supports corporate customers such as Mars, Inc. As one of the first mega-projects in South Texas, Los Vientos extended the state’s wind footprint into non-traditional areas and improved transmission access to urban centers.

Roscoe Wind Farm

Roscoe Wind Farm was the biggest onshore wind farm in the world at the time of its construction in 2009. The wind farm spanning nearly 100,000 acres across Nolan, Taylor, Mitchell, and Scurry counties near Abilene marked a turning point for large-scale renewable energy in the United States.

Developed and operated by RWE Renewables (formerly E.ON Climate and Renewables), the project delivers 781.5 megawatts of capacity through 627 turbines supplied by Mitsubishi, Siemens, and GE. The turbines, standing between 350 and 415 feet tall, were installed at an impressive pace of roughly one per day during peak construction.

Built in four phases between 2007 and 2009, the USD 1 billion project now generates enough electricity to power more than 250,000 Texas homes. Early phases began operation in 2008, and full operations started in October 2009.

Javelina Wind Energy Center

Located across Webb and Duval counties about 25 miles east of Laredo, the Javelina Wind Energy project is one of South Texas’s most productive renewable energy facilities. Developed by Bordas Renewable Energy and NextEra Energy Resources, the project was built in three phases between 2015 and 2018 and reached full operational capacity at 748.7 megawatts.

The wind farm includes 346 GE turbines ranging from 1.7 MW to 2.5 MW models. Javelina operates with an impressive capacity factor of about 43.1%, surpassing the national average for onshore wind projects. During the three-month period from April to July 2025, it generated 293.9 gigawatt-hours of electricity.

Electricity from Javelina is sold through long-term power purchase agreements with South Texas Electric Cooperative, Dow Chemical, and AT&T. The project plays a key role in supporting industrial and commercial renewable energy demand in Texas.

Horse Hollow Wind Energy Center

The Horse Hollow Energy Center, located across Taylor and Nolan counties near Abilene, was the world’s largest wind farm when it became fully operational in December 2006. Spanning nearly 47,000 acres, the 735.5-megawatt facility marked a major milestone in Texas’s rise as a global wind energy hub.

Developed and operated by NextEra Energy Resources, Horse Hollow was built in three phases between 2005 and 2006 by Blattner Energy. The project includes 421 turbines, 291 GE 1.5 MW units, and 139 Siemens 2.3 MW models that together generate enough power for roughly 220,000 homes.

Capricorn Ridge Wind Farm

Capricorn Ridge Wind Farm is one of the state’s most impactful renewable energy projects, located across Sterling and Coke counties in West Texas. Owned and operated by NextEra Energy Resources, the 662.5-megawatt facility was completed in two phases, one in 2007 and another in 2008, spanning about 11,000 acres within one of Texas’s designated Competitive Renewable Energy Zones (CREZ).

The project features 407 turbines, including 342 GE 1.5 MW units and 65 Siemens 2.3 MW models. Together, they generate enough electricity to power more than 220,000 homes each year. Capricorn Ridge also avoids an estimated 952,000 metric tons of carbon dioxide emissions annually, contributing meaningfully to Texas’s clean energy and emissions reduction goals.

In 2012, GE Energy Financial Services and JPMorgan Chase invested USD 225 million in the project. Capricorn Ridge was also the first U.S. wind farm to sell verified carbon offsets, setting a precedent for environmental accountability in renewable energy development.

Sweetwater Wind Farm

Located in Nolan County, Texas, the Sweetwater Wind Farm is one of the state’s earliest and most influential large-scale wind projects. Developed in five phases between 2005 and 2007, the facility began operations in 2007.

Spanning roughly 144 square miles, Sweetwater includes 392 turbines manufactured by GE, Mitsubishi, and Siemens, delivering a total capacity of 585.3 megawatts. When it was completed, it stood as the largest wind farm in Texas and the world.

Operated by Duke Energy and Leeward Renewable Energy, the project produces about 1.8 terawatt-hours of electricity annually, enough to power homes and businesses across Austin and San Antonio through long-term agreements with Austin Energy and CPS Energy.

Current and Future Outlook of Wind Farms in Texas - 2025

Texas’s wind power success comes down to a mix of geography, infrastructure, and policy. The state sits in a natural wind belt, giving it consistent and strong wind resources, especially in the Panhandle and West Texas. Decades of investment through the Competitive Renewable Energy Zones (CREZ) have connected these remote regions to major cities with nearly 500 miles of high-voltage transmission lines.

Today, Texas generates about 27% of all wind power in the United States, and its wind fleet continues to grow. Developers are repowering older projects like Roscoe and Sweetwater with taller towers and longer blades, boosting efficiency without expanding land use. Meanwhile, hybrid wind-plus-storage systems are being added to the ERCOT grid to reduce curtailment and improve reliability during peak demand periods.

Looking ahead, offshore wind is emerging as the next frontier. The Bureau of Ocean Energy Management (BOEM) is reviewing lease areas near Galveston, and future offshore projects could power millions of coastal homes. New developments such as Forest Creek and Honey Mesquite, expected to be operational by late 2025, will add more than 300 megawatts of capacity.

Conclusion

Texas’s top wind farms, including Great Prairie, Los Vientos, Roscoe, Horse Hollow, Capricorn Ridge, Javelina, and Sweetwater, represent America's wind energy transformation. Together, they deliver more than 5,000 megawatts of clean power, support thousands of jobs, and offset millions of tons of carbon emissions each year. As of 2025, the state's 42-gigawatt wind portfolio demonstrates the U.S. transformation in renewable energy production. By combining scale, innovation, and infrastructure, Texas continues to lead the nation toward a cleaner and more reliable energy future.
