Illinois’ 11 nuclear reactors generate 48% of the state’s electricity supply and account for more than 12% of the nation's nuclear power.
The State of Illinois reported in a recent study that Illinois’ electricity system would be “unreliable” under all premature plant closure scenarios. That finding is from the regional transmission grid operator, who came very close to experiencing rolling blackouts during the 2014 polar vortex. The study also reported that costs to construct transmission lines to address reliability issues would be significant – in the hundreds of millions of dollars more – and paid for by consumers in the form of higher rates.
