Big Stone II would be owned by Otter Tail, MDU, Central Minnesota Municipal Power Agency, Heartland Consumers Power District, & Missouri River Energy Services.

It would burn Powder River Basin coal

Clean Water Action and Sierra Club were two of the main opposition groups to Big Stone II. Big Stone II was defeated when the SD air permit granted in the last days of the Bush administration was overturned because the permit did not reflect a plan to use the best available control technology (BACT).
