Wind Mills in Texas: 2026 Directory of Largest Wind Farms and

Introduction: Texas Wind Energy at a Glance

Texas has always turned wide-open space into power—first oil, now wind. By 2026, the state has piled up over 45 GW of installed capacity, keeping it miles ahead of every other US wind market. More than 16,000 utility-scale turbines pump electricity into the ERCOT grid, covering a growing slice of daily load. The same Permian Basin and High Plains that once sprouted derricks now host some of the world’s largest onshore wind farms, tapping into a high-capacity-factor wind resource built for utility-scale generation. Below we profile the largest operating wind mills in Texas—the projects and developers shaping this onshore fleet.

How Big Are the Farms? A 2026 Power Directory

What follows is a ranked look at the biggest operating sites, plus notes on what keeps them productive.

Los Vientos Wind Farm (912 MW) — Starr County
Duke Energy’s Los Vientos holds the crown as Texas’s biggest wind site. Built in five phases between 2012 and 2016, its 411 turbines scatter across South Texas ranchland where cattle graze beneath the blades. The final 200 MW phase locked in its top ranking. A typical year yields more than 3 TWh, with Gulf Coast breezes keeping output high when inland sites ease off.

Roscoe Wind Farm (781.5 MW) — Nolan County
For a decade, Roscoe was the world’s largest onshore wind farm. Commissioned in 2009 and now operated by RWE, it spans roughly 100,000 acres and runs 627 turbines. The site still serves as a benchmark—its capacity factor stays above 35%. RWE has since pushed its total Texas wind portfolio beyond 3.5 GW through both acquisition and greenfield work.

White Mesa Wind Farm (500 MW) — Crockett County
Enel Green Power added White Mesa to the Texas grid in 2021. The 130-turbine project sits atop a corporate PPA structure that has widened Enel’s US footprint meaningfully.

Hale Wind Farm (478 MW) — Hale County
NextEra Energy Resources brought Hale online in 2019. The High Plains site runs 250 turbines in a single-phase build, with a long-term power purchase agreement covering most of its output. Few developers argue with the wind speeds up there.

Peñascal Wind Farm (404 MW) — Kenedy County
Iberdrola’s Peñascal, completed in 2010, uses 168 turbines and originally included an innovative battery storage demonstration. Its coastal position south of Corpus Christi delivers a steady production profile, adding a reliable slug of megawatt-hours to Iberdrola’s North American fleet.

Papalote Creek Wind Farm (380 MW) — San Patricio County
Brought online in two phases by E.ON (now part of RWE) in 2009–2010, Papalote Creek runs 196 turbines near Gulf Coast load centres. High availability has kept it quietly productive for over 15 years.

Bearkat I & II (416 MW combined) — Glasscock County
Developed by Copenhagen Infrastructure Partners and now managed by Longroad Energy, the two-phase Bearkat complex wrapped up in 2018 and 2020. Its 416 MW feeds directly into the Texas grid, serving a cluster of industrial offtakers in the region.

Turbine counts reflect original installation; some sites have undergone partial repowering. Bearkat blade count is a mix of re‑used units.

This table doubles as a decision‑support tool: if you’re evaluating a PPA counterparty, start with farms that show multi‑phase expansion and long‑term offtake—those patterns signal developer commitment and steady revenue.

Who Runs the Show? Major Wind Energy Developers and Owners

NextEra Energy Resources runs the largest wind fleet in the state, with more than 7.2 GW of in‑state capacity across 40 facilities. Key entries include the 478 MW Hale Wind Farm and the 300 MW Blue Summit Wind Energy Center. The company’s Texas pipeline tops 2 GW, mostly repowering efforts and new High Plains sites. A common mistake is to overlook the spread of a developer’s operating portfolio; NextEra’s density across ERCOT gives it a dispatch‑optimisation edge that a smaller player can’t match.

Invenergy manages a Texas portfolio surpassing 2.5 GW. The developer built the 302 MW Santa Rita Wind Energy Center and the 250 MW El Cabo Wind Farm, and shepherds assets from permitting through operations. Another 1.5 GW sits in late‑stage development.

RWE holds roughly 3.6 GW of Texas wind capacity after acquiring Con Edison’s renewable portfolio. Beyond Roscoe, the firm operates the 200 MW Cactus Flats Hill project and a string of smaller sites, making it one of the largest combined developer‑owner‑operators in the ERCOT region.

Enel Green Power has quickened its Texas clip with White Mesa and the 497 MW Roadrunner Solar‑plus‑storage project. Operational wind assets in the state total 1.9 GW, and the group keeps an eye on brownfield repowering plays across its installed base.

Duke Energy Renewables and EDP Renewables each hold more than 1 GW of operating wind in Texas. Duke’s Los Vientos remains the single largest project; EDP Renewables’ portfolio includes the 205 MW Wildcat Wind Farm and a handful of distributed‑generation installations.

Why Texas? The Grid and Wind Engine That Keep the Mills Turning

Two forces separate Texas from other wind markets: the resource itself and the ERCOT market design. Wind speeds across the High Plains consistently produce capacity factors above 35%, and the coastal Gulf profile often peaks during summer afternoons when load and pricing are highest. In practical terms, a diversified wind portfolio—mixing High Plains bulk energy with coastal timing—beats a single‑region bet.

The grid side is equally important. ERCOT operates as an energy‑only market without a capacity‑payment mechanism. That means wind mills in Texas earn revenue only when they generate, which pressures developers to chase high‑capacity‑factor sites and to layer in storage. Meanwhile, the state’s “Competitive Renewable Energy Zone” transmission corridors, built over a decade ago, still funnel billions of dollars of wind output from West Texas to load centres. As of mid‑2025, the interconnection queue shows more than 12 GW of planned new wind capacity. If realisation rates hold, annual additions of 2–3 GW through 2028 will push total installed capacity past 50 GW. The bottleneck, as always, is whether new transmission can keep pace—a detail that generic market summaries often miss.

Frequently Asked Questions

How many wind turbines are there in Texas in 2026?
More than 16,000 utility‑scale turbines operate across the state. This count, drawn from ERCOT interconnection filings and completion data through 2025, excludes residential‑scale and behind‑the‑meter machines. The number has grown steadily as repowering swaps older, smaller turbines for fewer but taller units that produce more energy per tower.

What is the purpose of wind mills in Texas?
Modern wind turbines generate electricity for the ERCOT grid. In 2025 wind supplied over 28% of the state’s total electric load, displacing fossil fuel generation during high‑output hours and bolstering grid reliability. The direct purpose is utility‑scale power delivery, not mechanical pumping—the “windmill” label is a colloquial holdover from ranching days.

Do wind turbines cause tinnitus?
No direct causal association has been demonstrated. Reviews by the US National Institutes of Health and large epidemiological studies find no evidence linking turbine infrasound to hearing disorders or permanent damage. Some residents report subjective annoyance, but that falls under sound perception, not an auditory injury.

Which city in Texas has the most wind mills?
Sweetwater, in Nolan County, anchors the state’s densest turbine cluster. The county holds over 1,200 turbines from major farms such as Roscoe and neighbouring projects, giving the area its informal reputation as Texas’s wind capital. The term “wind mills in Texas” still often points visitors toward this stretch of I‑20.

How much wind capacity will Texas add in the near future?
Annual additions of 2–3 GW are expected through 2028, based on the 12 GW of wind projects sitting in ERCOT’s interconnection queue as of mid‑2025. Actual construction depends on transmission upgrades and PPA demand, but Texas continues to lead US onshore wind growth.

Conclusion: The Future of Texas Wind Mills

Texas’s wind development pipeline remains full: repowering of legacy sites and large‑scale greenfield projects keep pulling in capital. Planned transmission expansions and a steady corporate appetite for PPAs should sustain a favourable investment climate, keeping the state atop the US onshore wind market. How much of those queued gigawatts actually turns into steel in the ground will depend on whether grid upgrades keep pace—and on a market that still rewards the windiest, least‑congested sites first.
