In an order on remand from federal court, FERC found it could no longer accept a 2011 MISO filing implementing its capacity market design as just and reasonable, after the changes adopted by FERC in an order conditionally approving the mechanism were found to be beyond FERC's procedural authority in addressing the tariff filing.
