Looking at my Texas (ERCOT) numbers now - Still on rolling blackouts. Wind generation is around 4000 MW, with an alleged capacity of over 21,000 MW.
Now granted, they will only put out as much electricity as the wind will allow, so for a light breeze, there will be less generation.
But to the extent that some are iced up, they are completely unavailable in that condition. I don’t really know how much of the reduction is due to non-optimum wind and how much due to unavailability of individual windmills.
I also don’t know the gas situation, but unavailable gas has been an issue as well. Takes a lot of windmills to equal one combined cycle gas generating plant, so if gas is unavailable at a specific plant, unless it can run on oil (big $$$), they’re off line.
This is the first time I have ever heard of blackouts due to lack of fuel stocks. Somebody soiled the bed here, this is bad.
