MISO is considering changes to its proposed forward capacity auction for Zone 4 in the face of opposition from its Market Monitor.

Exelon said it will close Clinton next summer and Quad Cities the following year if Illinois legislators fail to pass a bill to shore up the nuclear plants.

Dynegy said it will idle as much as 30% of the capacity in Illinois because their units can’t recover their costs from the MISO energy and capacity markets.

The appeal lent support to Illinois legislation that would shore up Exelon’s struggling nuclear plants with $300 million per year.
