Ohio's 2025 statewide residential average was 16.90¢. July 2026 was 19.45¢, versus 17.38¢ in July 2025 (+11.9%). Compare each The Illuminating Company service type with those figures on its own.

Revenue 169,992 thousand dollars. Sales 1,048,189 MWh. Customers 137,419. Cents per kWh = revenue ÷ megawatt-hours × 100. Monthly bill = revenue × 1,000 ÷ customers ÷ 12.

Hold a The Illuminating Company household to the filing average and the monthly delivery only bill changed +2.2% between those two EIA years. Holding the 2024 price fixed, the usage change of +3.6% is worth $1.90 a month. The price change of −1.3%, from 7.81¢ to 7.71¢, is worth −$0.73 on 2025 usage.
7.71¢ per kWh is below Ohio's 2025 residential average of 16.90¢. July 2026 in the state was 19.45¢, versus 17.38¢ a year earlier (+11.9%). The utility figure is a full year of average revenue. The state figure is one later month. A household that uses more than 708 kWh will not land on $54.59.
The Illuminating Company reported more than one residential service with a real customer count: 137,419 full service customers at 16.22¢; 540,162 delivery only customers at 7.71¢. Bundled customers buy supply and delivery together. Delivery customers buy supply from someone else. A single blended rate would describe neither bill.
The 2025 monthly average for this The Illuminating Company service was 708 kWh, and the Ohio residential average was 874 kWh. A single month can sit far from either figure. Compare kilowatt-hours with the same month last year before you treat the whole increase as a rate hike.
EIA's 2025 dynamic-pricing file shows residential time-of-use activity at The Illuminating Company, with 53 residential customers enrolled in dynamic pricing. The expensive window is in the tariff, not in that enrollment count. Shifting a dishwasher or an EV charger only helps if you are actually on that schedule.

Using 2025 EIA-861 revenue and sales, the delivery only average was 7.71¢ per kWh. Average use was 708 kWh a month and the average bill was $54.59. This folds in whatever customer charges and riders the utility reported. It is not the marginal rate on your tariff.
The delivery only average price changed −1.3% from 2024 to 2025, from 7.81¢ to 7.71¢. That is average revenue per kilowatt-hour, not a commission order. No 2025–2026 order for this utility was retrieved for this page. A separate rider can still move a single month.
