DULUTH — The Trump administration is terminating a $50 million grant to modernize a Minnesota Power transmission line linking North Dakota and Hermantown, Minnesota. Construction on the $940 million project is already underway. Minnesota Power said it was aware of the DOE's announcement but, as of Thursday afternoon, had not heard directly about the status of its grant. Minnesota Power said it is working with the delegation of federal lawmakers and "will evaluate next steps" during the 30-day window. Minnesota Power has for years been planning to upgrade the 465-mile HVDC transmission line stretching from Center, North Dakota, to Hermantown.
