I can answer that question. Someone posted up-thread that two coal plants have gone down. They froze over or something.
Doh! Can = can’t.
It looks like there was a problem at 2 power plants.
” Burst water pipes at two coal-fired power plants forced them to shut down, triggering rolling power cuts across the state, the lieutenant governor said Wednesday.”

Busted Pipes causing power plants to go down would make sense.
But it doesn’t match what has been reported thatthe “grid was overloaded”.
