In June 2016, Mississippi Power was sued by Treetop Midstream Services over cancelation of a contract to receive carbon dioxide from the Kemper Project as part of the carbon capture and storage design. Treetop had contracted to buy carbon dioxide from the Kemper plant and had built a pipeline in preparation to receive the gas. Treetop alleged Mississippi Power had fraudulently and "intentionally misrepresenting and concealing the start date" for the Kemper Project, though Mississippi Power stated the suit was without merit.
