Enel SpA through its US-based renewables subsidiary Enel Green Power North America Inc., started operations of the Thunder Ranch wind farm, which has a capacity of around 298 MW, and of the Red Dirt wind facility, which has a capacity of around 300 MW, both located in Oklahoma. As a result, EGPNA has become the large wind player in the state, with more than 1,700 MW of managed capacity across 10 wind farms. The investment in the construction of Thunder Ranch totalled around USD 435 million, while the investment in the construction of Red Dirt was approximately USD 420 million. Both amounts are part of the investment outlined in Enel’s strategic plan. The Thunder Ranch wind farm, located in Garfield, Kay and Noble counties, is able to generate more than 1,100 GWh annually. The plant will be the first of EGPNA’s wind farms to have an operational rooftop solar PV system that will power its operations and maintenance building with around 55 kWh per year. The rooftop system is expected to be completed by the first quarter of 2018. Thunder Ranch is fully contracted with long-term agreements, including one power purchase agreement with Anheuser-Busch, the US subsidiary of leading beer corporation AB InBev, for a 152.5 MW portion of the wind farm. The Red Dirt wind farm, located in Kingfisher and Logan Counties, is able to generate approximately 1,200 GWh each year. Red Dirt is supported by two long-term power purchase agreements, one with T-Mobile US Inc. for a 160 MW portion of the wind farm and another for the remaining 140 MW portion with the Grand River Dam Authority, which will sell the renewable energy to Google under a separate agreement between the two. In Oklahoma, in addition to Thunder Ranch and Red Dirt, the company already manages the wind farms Rocky Ridge (150 MW), Chisholm View I & II (300 MW in total), Origin (150 MW), Osage Wind (150 MW), Little Elk (74 MW), Goodwell (200 MW) and Drift Sand (108 MW). The company’s overall investment in Oklahoma amounts to more than USD 2.7 billion since 2012.
