BISMARCK — State utility regulators approved a large wind farm in oil-rich western North Dakota Tuesday, May 7.

The Aurora Wind Project is slated for a 44,000-acre site five miles northwest of Tioga. It will consist of up to 121 turbines with a maximum capacity of 300 megawatts and is expected to cost $385 million.

North Dakota has 3,155 megawatts of installed wind capacity, good for 10th in the nation, according to the American Wind Energy Association.

The North Dakota Public Service Commission issued a siting permit for the wind farm during a special meeting Tuesday afternoon. Commissioner Julie Fedorchak said the developer hopes to have the project operational by the end of 2020.

Tradewind Energy proposed the project and plans to connect it to a Basin Electric substation in Mountrail County via a transmission line.
