August 22, 2014, Dynegy announced a deal involving two interdependent transactions to be executed simultaneously. Dynegy acquired Duke’s Midwest Generation assets and retail business for $2.8 billion in cash, and the power generating assets of EquiPower Resources for $3.45 billion, with $3.35 billion in cash and $100 million in stock. This increased the company's generating capacity from 13000 MW to nearly 26000 MW. Acquisition by Vistra On April 9, 2018, Vistra Corp closed its acquisition of Dynegy following a FERC determination that the $1.7 billion deal raised no competitive concerns. Controversy In June 2021, the Attorney General of Illinois filed a lawsuit against Dynegy claiming that the company polluted groundwater with contaminants from coal ash.
