How ComEd’s plans work
BES (Basic Electric Service, single family (no electric space heat)). One price per kWh at every hour: 15.9¢ in July and 18.6¢ in January. Shifting use to other hours changes nothing on this plan; using less is the only lever. Fixed charge: $19.99 a month.
DTOD (Delivery Time-of-Day Pricing (fixed-price ComEd supply), single family (no electric space heat)). Super off-peak 12 am–6 am, Mid-peak 6 am–1 pm, Peak 1 pm–7 pm, Super off-peak 9 pm–12 am on July weekdays; 6 of 24 hours carry the top price of 21.2¢. The cheapest July weekday hour costs 13.1¢, so moving 1 kWh out of the top hours saves 8.1¢. January weekdays range from 15.8¢ to 23.9¢. Summer pricing applies Jun–Sep; winter pricing Oct–May. Fixed charge: $19.99 a month.
Prices on this page are all-in per kWh, before taxes: base rates, supply and every per-kWh rider in the utility’s current tariff sheets. Your bill shows them as separate lines, and riders can change between tariff revisions.
As a cross-check, ComEd billed its residential customers an average of 17.71¢ per kWh in 2025 (revenue ÷ sales, EIA-861). A plan taken from URDB is shown only if its all-in price is consistent with that figure, adjusted for Illinois’s price change since.
