How Delmarva Power’s plans work
R (Residential Service). One price per kWh at every hour: 22.9¢ in July and 23.7¢ in January. Shifting use to other hours changes nothing on this plan; using less is the only lever. Fixed charge: $9.75 a month.
R-TOU-ND (Optional Residential Time of Use Non Demand). Peak 2 pm–7 pm on July weekdays; 5 of 24 hours carry the top price of 27.4¢. The cheapest July weekday hour costs 21.8¢, so moving 1 kWh out of the top hours saves 5.6¢. January weekdays range from 20.2¢ to 36.2¢. Summer pricing applies Jun–Sep; winter pricing Oct–May. Weekends differ: off-peak all day. Fixed charge: $9.75 a month.
R-PIV (Residential With Plug-In Vehicle Charging Service). Peak noon–8 pm on July weekdays; 8 of 24 hours carry the top price of 31.2¢. The cheapest July weekday hour costs 19.8¢, so moving 1 kWh out of the top hours saves 11.4¢. January weekdays range from 20.0¢ to 37.8¢. Summer pricing applies Jun–Sep; winter pricing Oct–May. Weekends differ: off-peak all day. Fixed charge: $9.75 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, Delmarva Power billed its residential customers an average of 21.81¢ 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 Maryland’s price change since.
