Square Butte is the designation of a high voltage direct current transmission line in the USA between the Milton R. Young Power Plant near Center, North Dakota at 47°4¿18¿N 101°11¿45¿W and the Arrowhead converter station near Adolph, MN (a suburb of Duluth, Minnesota) at 46°46¿25¿N 92°17¿39¿W. It was built by Minnkota Power Cooperative and Minnesota Power and went in service in 1977. Recently, an agreement was executed between the two companies whereby Minnkota gets the rights to all the power currently transmitted over the line (and will build a new line to carry said power later) while Minnesota Power takes full ownership of the line to transmit power from new sources in the Center area.
