Why the Illinois bill is what it is
A bill is kilowatt-hours multiplied by price, and states reach similar bills by very different routes. Illinois's electricity costs 4% less than the U.S. average, and the typical Illinois home uses 20% less of it, so the bill lands 23% below the national average. Both work in the same direction: price and usage are each below the national figure.
Compare North Dakota: households there pay almost the same bill ($118.38 against $109.99) at a rate 73% of Illinois's — 11.51¢ against 15.87¢ — because they use 1,029 kWh a month where Illinois homes use 693.
At today's rate
The 2024 figures are the latest annual numbers EIA has published. Illinois's average residential rate has since moved to 19.89¢/kWh (June 2026). At the same 693 kWh a month, that puts the typical bill near $137.86 — 25% higher. That is an estimate: it holds usage at 2024 levels, and usage swings with the weather.
