Roadrunner Solar Project

Built in record time and equipped with double-faced solar panels, the plant has created hundreds of local jobs, becoming a symbol and role model of innovation and sustainability.

About the plant

The giant of Texas

Located in Upton County in West Texas, the Roadrunner solar project will be the largest operational solar project in Texas upon completion of its second phase, expected in late 2020.

With 1.2 million bifacial panels and a total capacity of 497 MW, Roadrunner will be the largest solar project in Enel’s US portfolio. Construction began in February 2019 and operations at the first 252 MW phase started in December 2019. Roadrunner’s second 245 MW phase is scheduled to begin operations by the end of 2020. The full project, sited across approximately 2,770 acres, will be able to generate 1.2 TWh annually while avoiding the emission of over 800,000 tons of CO2 per year.

Our Corporate Partners

Enel Green Power has partnered with food and beverage company Mondelēz International on a 12-year, 65 MW Power Purchase Agreement (PPA) at Roadrunner Solar Project. The energy sold is enough to produce over 50% of all the Oreos consumed in the US annually, equivalent to around 10 billion cookies, and will reduce Mondelēz International’s annual CO2 emissions by 80,000 metric tons. The agreement is Mondelēz International’s largest renewable energy partnership at global level and their first renewable energy PPA signed in the US. Moreover, it enables the food and beverage leader to make substantial progress against the company’s new 2025 Impact Goals which provide a clear roadmap to reduce the company’s environmental footprint.

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.

Community Impact

Enel Green Power is committed to creating long-term shared value for the community and the company and plans to make local investments focused on education and emergency response. On behalf of the Roadrunner solar project as well as the nearby High Lonesome wind project, Enel Green Power has provided support in McCamey, Texas, for the McCamey Wellness Center and a forthcoming downtown farmers market. Over the life of the project, Roadrunner will generate approximately $60 million in new tax revenue for the local community.

Work Progress Status

Construction of the first phase of the Roadrunner solar project took place throughout 2019. While operations have begun at the first phase, construction is now underway on the second phase, with operations expected by the end of 2020. The construction process follows 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.
