My understanding is that there is a seasonal "online / maint" cycle
for the generation plants, and that many of them were not taken
offline for normal PM several months ago because of energy usage
_then_...  my unsubstantiated guess would be that just like letting
your car go 30,000 miles between a pair of oil changes,
procrastination of the maint cycle eventually comes home to roost and
that's what we're seeing now.
