High Lonesome Wind Farm

In Texas, the leading state in the US’s renewables market, the American wind farm is the largest in Enel’s global operational portfolio. Moreover, Enel’s innovative off-take strategy is ushering in a new chapter of PPAs.

About the plant

Wind from Texas

Located in Upton and Crockett counties in West Texas, the High Lonesome wind farm is approximately one mile south of the city of Rankin and 15 miles east of McCamey – the “Wind Energy Capital of Texas.”

With 164 turbines and a total capacity of 500 MW, High Lonesome is the largest operational wind farm in Enel’s global portfolio. Construction began in January 2019 and operations at the first 450 MW portion of the project started in December 2019. The project, sited across a 200-square-mile footprint, can generate 1.9 TWh annually while avoiding the emission of 1.2 million tons of CO2 per year.

Proxy Revenew Swap

The PRS is a financial derivative agreement which hedges shape risk in addition to risk associated to price and volume.

Signing of new PPA

Enel Green Power expands High Lonesome to 500 MW through new PPA with Danone North America.


Enel Green Power starts operations at a 50 MW expansion to the project supported by a 20.6 MW PPA with food and beverage company Danone North America.

Our Corporate Partners

At High Lonesome, Enel Green Power has partnered with leading food and beverage company Danone North America — parent company to beloved brands including Silk, So Delicious, Horizon Organic and Light & Fit, and the world’s largest Certified B Corp — on a 20.6 MW power purchase agreement (PPA). That’s enough electricity to produce the equivalent of 800 million cups of yogurt and over 80 million gallons of milk annually. The agreement between Enel and Danone North America will support the food and beverage leader in its commitment to secure 100% of its purchased electricity from renewable sources by 2030.

In addition, Enel will sell the energy produced by a 295 MW portion of the project under a Proxy Revenue Swap (PRS) to insurer Allianz Global Corporate & Specialty, Inc.'s Alternative Risk Transfer unit (Allianz), and Nephila Climate, a provider of weather and climate risk management products. The PRS is a financial derivative agreement designed to produce stable revenues for the project regardless of power price fluctuations and weather-driven intermittency, hedging shape risk in addition to risk associated to price and volume.

At Roadrunner, Enel is also partnering with The Clorox Company on  a 12-year, 70 MW PPA . Representing about half of Clorox's 100% renewable electricity goal in its operations in the US and Canada, this agreement is expected to help Clorox accelerate achieving its goal in 2021, four years ahead of the company's original plan.

Work Progress Status

Construction of the High Lonesome wind farm took place throughout 2019 and is mostly complete, as the project began operations in December. The construction process followed Enel Green Power’s Sustainable Construction Site model, a collection of best practices aimed at minimizing the impact of plant construction on the environment, waste, water and people.

Sustainability Practices:

Construction offices used water dispensers and reusable canteens to reduce single-use plastic water bottle use. Paper, cardboard, aluminum, ink cartridges, oil and grease were recycled responsibly, and paper waste was reduced by iPad usage. Solar-powered lights were used during construction, and a solar photovoltaic system has been designed for the permanent operations building.

Digital Initiatives:

Drones were used for road surveys and monitoring construction progress. The ARC GIS application was utilized to quickly transmit information between workers. A 360-degree camera was utilized to record construction activities iPads were used in the field to access drawings and other construction-related documents.
