Basin Electric’s project will require 77 wind turbines, while Rough Rider Wind, a subsidiary of NextEra Energy Resources LLC, expects to put up 116 towers, commission documents say. Both projects are anticipated to be completed by early 2010.

Kevin Cramer, the commission’s chairman, said North Dakota now has turbines capable of generating a peak amount of 713 megawatts of electricity. In 2001, “we had nothing,” Cramer said.
