Possible online services disruption due to Internet related outage

A worldwide technology outage is causing disruption to some State of Illinois online systems.  We are aware of this issue and are diligently working on restoration.

Electricity Generation Mix

Did you know Illinois has a diverse electricity generation mix, which serves to enhance energy reliability?

As of 2022, Illinois generates 53.38% of electricity from nuclear power, 32.89% from fossil fuels (comprising of coal, natural gas, petroleum, and other gases), and 13.73% from renewables (comprising of wind, solar, hydropower, and biomass).  As far as renewable resources go, wind is leading as the state’s primary renewable energy source. In Illinois, a significant portion of the electricity mix is transitioning towards renewable sources. In 1990, renewable energy accounted for only 0.23% of Illinois' total in-state electricity generation. In 2022, that number has increased to 13.73%.  With tens of thousands of new solar projects coming online, solar generation is poised to increase to help meet consumer interests and demand as well as state climate goals.

As the nation’s top nuclear power generator and fifth-largest electricity producer, Illinois generates more electricity than it consumes and is a net exporter or electricity.
