Why Illinois's bill lands where it does

The lowest bill of the states we cover: a low price (15.87¢) and low-to-moderate usage (693 kWh), helped by Chicago-area housing density and prevalent gas heat.

It's worth separating the two: a bill is price × usage. Illinois's price is 15.87¢/kWh (0.6¢ below average) and its usage is 693 kWh (170 kWh below average). Neither runs high, which is why the bill is low.

What makes up that 15.87¢/kWh

The all-in price isn't all "the electricity." Of Illinois's 15.87¢/kWh, the supply (generation) portion — the part you can sometimes shop — averages around 10.86¢ across the utilities we track, roughly 68% of it. The rest is delivery, fixed charges, and taxes, which you can't shop.

That supply piece is also where 2025–26 increases landed (the PJM capacity spike). See your utility's rate change →
