It’s partnering with California company Antora and Minnesota-based Otter Tail Power to launch a new clean energy project near its Big Stone City plant. Otter Tail is asking state regulators to approve power agreements for both Antora and POET, with a vote set for today.  The move comes after South Dakota banned CO2 pipeline projects.
