GE Energy Financial Services is investing $141 million in the Tatanka Wind Farm, which spans 14,000 acres along the border of North Dakota and South Dakota. Wachovia Investment Holdings LLC also provided financing for the project, which went online last month.
The farm is owned and operated by Acciona Energy North America. It is the first U.S. wind farm built entirely by Acciona, the companies said.
"The Dakotas' high wind energy potential and low population means that wind power will be available to transmit to the rest of the Midwest," Susan Nickey, chief financial officer of Acciona's North American unit, said in a statement.
The Tatanka wind farm is the largest in the Dakotas, which are among the top U.S. states for wind energy potential.
