How Duke Energy Carolinas’s plans work

RS (Residential Service). One price per kWh at every hour, all year: 14.4¢. Shifting use to other hours changes nothing on this plan; using less is the only lever. Fixed charge: $15.35 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, Duke Energy Carolinas billed its residential customers an average of 13.94¢ per kWh in 2024 (revenue ÷ sales, EIA-861). A plan taken from URDB is shown only if its all-in price is consistent with that figure, adjusted for North Carolina’s price change since.
