Minnesota Power completed commissioning the latest phase of its Bison Wind Energy Center. The 205-MW expansion makes it the largest wind farm in North Dakota. All 64 turbines within the 35-square-mile boundaries of Bison 4 are now generating renewable energy, which is delivered to the company's customers via a 465-mile direct current transmission line linking Center, N.D., and Duluth, Minn. In total, the nearly 500 MW produced by Bison's 165 turbines rank it as North Dakota's largest wind farm in terms of electric generating capacity.
Bison Wind Energy Center
Siemens Energy was awarded an order by Minnesota Power for 64 units of the company's latest 3-MW D3 platform wind turbines to be installed at the Bison Wind Energy Center near New Salem, North Dakota. The wind turbines feature a 113-meter rotor and 92.5-meter hub height and thus increased rating of 3.2 MW. Installation of the turbines is scheduled to begin in mid-June 2014, and commercial operation is slated for December 2014.
