A high voltage power line that runs from near Duluth, Minnesota to just outside of Bismarck, North Dakota will soon convert to carrying clean wind energy power.

This story from Minnesota Public Radio says Duluth-based Minnesota Power bought the 250-kilovolt power line from the Square Butte Electric Cooperative:

“We’ll be phasing out coal-based electricity that is currently carried via the D.C. line, and that will be replaced entirely by wind energy over the next several years,” [Minnesota Power Spokeswoman Amy Rutledge] said. “It will afford us access to some of the best wind resources in the country, and provide us with the means to deliver more renewable energy to our customers.”

Rutledge said the purchase will save Minnesota Power the cost of permitting and building a new power line. Minnesota Power is planning a 75-MW wind farm to generate power near New Salem, North Dakota.

The wind energy carried on the line is expected to help Minnesota Power meet a state mandate of 25 percent renewable energy by 2025.
