A northern Minnesota utility broke ground this week on a $900 million electric transmission project that’s expected to play a critical role in the state’s clean energy transition.

Duluth-based Minnesota Power is upgrading and expanding a 50-year old high voltage direct current (HVDC) transmission line that runs 465 miles from Center, N.D., to Solway Township, just outside Duluth.

It’s one of just two HVDC lines in Minnesota, and there are only a few across the country. They’re valuable because they transmit electricity more efficiently over long distances than more common alternating current, or AC, lines.
