Nearly a decade on, the saga over Dynegy’s manipulation of MISO’s capacity market continues, with FERC denying the company’s asks for procedural changes that might have softened repercussions in the case.

Nearly a decade after the MISO capacity auction in which Dynegy was found to have manipulated clearing prices, FERC has directed hearing and settlement procedures in the case.

FERC said it will take another look into whether Dynegy manipulated pricing in MISO’s 2015/16 capacity auction and violated federal laws.

FERC denied what might be a final bid to recalibrate the results of MISO’s 2015/16 capacity auction, blocking Public Citizen’s request for rehearing.

Public Citizen asked FERC to rehear its ruling dismissing complaints over MISO’s 2015/16 capacity auction, saying it failed to justify its findings.

FERC capped a three-year-old investigation into MISO’s 2015/16 Planning Resource Auction by finding no market manipulation on Dynegy’s part.

MISO stakeholders will vote on whether to broaden export limits for its upcoming capacity auction after WPPI Energy called for the RTO to act.

FERC said that MISO can use the PJM technology-specific reference levels for market mitigation in its 2017/18 capacity auction.

MISO will not yield on a planned July filing for capacity auction design changes, while a filing to add seasonal and locational constructs will be delayed.

MISO continues to move forward with modifications to its capacity market even as some stakeholders question the need for the proposed auction changes.
