SUGAR LAND--March 18, 2016--Written by John Egan for Industrial Info Resources (Sugar Land, Texas)--Plans by Minnesota Power (MP) (Duluth, Minnesota), a subsidiary of ALLETE Incorporated (NYSE:ALE) (Duluth), to build a 224-mile, 500 kilovolt (kV) transmission line connecting Minnesota and Manitoba took a step forward late last month after the Minnesota Public Utilities Commission (MPUC) approved the route for the proposed line. Because the line crosses international boundaries, the utility needs a presidential permit before it can begin construction of the Great Northern Transmission Line (GNTL). Minnesota Power said it expects to receive that permit in the coming weeks. Within this article: Mentions the price range as well as the engineering services provider contracted for the project.
