About Big Stone II

The Big Stone II Project involves the construction of an approximately 600-MW, coal-fired generating facility near Milbank, in Grant County, S.D. The Big Stone II generating unit would be located next to the existing Big Stone Plant, and would require new or upgraded transmission lines in the area. Two transmission alternatives are proposed in South Dakota and Minnesota. Voltage on the proposed transmission lines would most likely be 230 kV.
