Case Update: United States v. Osage Wind, LLC

In a cautionary tale for renewable energy developers operating on split estates, the United States v. Osage Wind, LLC litigation continues to carry significant legal and practical implications. In late 2023, the U.S. District Court for the Northern District of Oklahoma issued a permanent injunction directing Osage Wind, LLC ("Osage Wind") to dismantle its wind farm in Osage County, Oklahoma, after more than a decade of litigation.¹ In March 2025, Osage Wind obtained a temporary stay of that order while it challenges the decision on appeal.² Although the stay temporarily delays enforcement and the court's findings remain subject to appeal, the case reinforces the legal risks that wind developers face when seeking to develop projects involving split surface and mineral estates.
