EDP Renewables will sell electricity from the 104MW Crossing Trails wind farm in Colorado to Tri-State Generation and Transmission Association under a 15-year power purchase agreement.
The deal will enable the continued development and construction of the project, which is expected to come online in 2020.
Crossing Trails is located south of the town of Seibert in Kit Carson and Cheyenne Counties.
Tri-State is a wholesale cooperative power supplier owned by 43 member electric cooperatives and public power districts.
Tri-State chief executive Mike McInnes said: “Tri-State continues to responsibly add emission-free renewable energy resources that are beneficial to our members.
“We are pleased to work with EDP Renewables to bring this investment to Colorado and the service territory of our member, KC Electric Association.”
EDPR North America chief executive Miguel Prado said: “EDP Renewables and Tri-State’s partnership represents our commitment to continuing to increase the clean energy landscape in the US.
“EDPR is pleased to enter in to the state of Colorado and provide cost-effective, emissions-free energy through its Crossing Trails wind farm.”
