Illinois at a glance
Illinois has one of the largest nuclear fleets in the country, which keeps generation costs low, but PJM and MISO capacity charges have risen sharply and now drive most of the upward pressure on bills. Retail choice is available, so shopped rates differ from the average. Cold winters and humid summers both contribute meaningfully to annual consumption.
