After more than two years, Ameren Missouri has not yet delivered suitable redress for more than a decade’s worth of Clean Air Act violations via its Rush Island coal plant.

FERC once again has determined the continuing payments MISO is making to a Wisconsin coal plant to stay online to sustain system reliability might be too steep.

A Wisconsin coal plant kept online for the sake of reliability will receive smaller monthly payments from MISO, FERC ruled in a settlement approval.

Ameren Missouri appears to be making good on plans to close its Rush Island coal plant, which has racked up multiple Clean Air Act violations.

FERC OK'd a settlement to reduce payments to a Missouri coal plant under its system support resource agreement with MISO.

FERC approved a MISO system support resource (SSR) agreement that will keep a Wisconsin coal plant operating for reliability purposes.

MISO is headed for another System Support Resource designation to keep a Wisconsin coal plant operating unless stakeholders present a viable alternative.

FERC approved an agreement that will keep an Ameren Missouri coal plant online past its planned retirement date to maintain MISO grid reliability.

MISO is all but certain to enact a set of changes to its study process for retiring generators, stakeholders learned last week.

MISO is proposing a makeover of its generator retirement studies that includes more notice and stiffer adherence to local reliability requirements.
