(Minot, ND) — Two of North Dakota’s oldest wind turbines have come down. The turbines at Basin Electric Power Cooperative’s Minot Wind facility were among the first in the state to stop operating. The co-op built them 20 years ago next to U.S. Highway 83 south of Minot. Basin Electric officials say the turbines had reached the end of their useful life and that parts and service were no longer available. The towers were 200 feet tall.
