What lighting costs here
Across 24 plans priced in Illinois, lighting adds $66.12 to $66.12 a year — $5.51 to $5.51 a month. The median plan puts lighting at $66.12 a year.

What Illinois homes use
EIA's 2020 residential survey found 622 kWh a year across 530 sampled homes that run one, near the national 654 kWh. The middle half spans 176 kWh to 785 kWh, so lighting varies by 609 kWh between one household and another.
Every light fixture and lamp in and immediately outside the home. That average covers all homes — 100% of homes here.
That makes lighting about 7% of the electricity an Illinois home uses. The remaining 7,830 kWh is what lighting is billed on top of, and on a tiered or time-of-use plan that is what sets the rate it meets.
Light and heavy use of lighting
A household in the lighter quarter runs lighting for 176 kWh a year and pays $18.64 on the cheapest plan. One in the heavier quarter runs it for 785 kWh and pays $83.40 — $64.76 more for lighting on the same tariff.
