I am conflicted on this. It's what I have been saying though, the cost to run a nuclear plant keeps them from running as much as they need to to keep costs down.
Wind farms contributed to only 7% of Illinois electricity in 2019 so it would seem most of this is from Nat Gas plants.
From one of the following tweets:
Together the plants employ 1,500+ full-time & another 2,000+ skilled workers during refueling outages, most from local union halls. The plants pay nearly $63 million in taxes annually to support local schools, fire, police and other services.
