How Duke Energy Florida’s plans work
RS-1 (Residential Service). In July the first 1,000 kWh a month cost 13.5¢ each; then 15.4¢ above 1,000 kWh a month. An average Florida home (1,477 kWh in July) goes past the first tier, so extra load such as an EV is priced higher. Fixed charge: $14.35 a month. Minimum bill: $30.00 a month.
RST-1 (Residential Time-of-Use). Mid-peak 6 am–6 pm, Peak 6 pm–9 pm, Mid-peak 9 pm–12 am on July weekdays; 3 of 24 hours carry the top price of 17.9¢. The cheapest July weekday hour costs 10.8¢, so moving 1 kWh out of the top hours saves 7.1¢. January weekdays range from 10.8¢ to 17.9¢. Summer pricing applies Mar–Nov; winter pricing Dec–Feb. Weekends follow a different schedule from weekdays. Fixed charge: $14.35 a month. Minimum bill: $30.00 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 Florida billed its residential customers an average of 16.63¢ 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 Florida’s price change since.
