Minnesota Power's Latest Wind Turbines Spinning

(Duluth News Tribune)

Minnesota Power said today that the latest installment of wind-powered electrical generators in North Dakota are spinning and sending electricity into the grid.

The Duluth-based utility said the addition of 70 new Siemens wind generators to its Bison wind energy farm near New Salem, N.D., is complete. The units were tested in recent weeks and officially commissioned this week, said Amy Rutledge, spokeswoman for the utility.

The Bison project was finished ahead of schedule in 2012 to qualify for a federal wind energy tax credit that may not be available next year.
