Duke Energy price per kWh in 2026 by state — NC ~15.5¢, FL ~14–16¢ (25% summer cut), IN ~15¢, plus the pending 11.6% Carolinas hike for 2027.
Duke Energy's residential cost per kWh ranges from about 13¢ in Kentucky and Ohio (delivery-only) to about 16.4¢ for Duke Energy Progress customers in eastern North Carolina. Duke Energy Carolinas is about 15.5¢/kWh, Duke Energy Florida is 14–16¢/kWh (with a 25% summer reduction in 2026), and Duke Energy Indiana is about 15¢/kWh. These are all-in effective rates including base charges, fuel adjustment, and environmental riders.
Duke Energy Progress and Duke Energy Carolinas are separate operating companies with different generation mixes, legacy costs, and territory profiles. Duke Progress serves eastern North Carolina and coastal South Carolina, while Duke Carolinas serves western NC and upstate SC. Progress customers pay about $18–$20/month more for 1,000 kWh of usage due to structurally higher fuel and rider charges.
Duke Energy Carolinas filed a rate case in November 2025 requesting an 18% residential rate increase over two years. After objections from the North Carolina Attorney General and other intervenors, Duke lowered its request in June 2026 to 11.6% (7.5% in 2027 and 4.2% in 2028). The North Carolina Utilities Commission is expected to rule this fall, with new rates taking effect January 1, 2027 if approved.
For a typical 1,000 kWh residential customer in 2026, Duke Energy Carolinas customers pay about $145/month, Duke Energy Progress customers pay about $164/month, Duke Energy Florida customers pay $140–$160/month depending on season, and Duke Energy Indiana customers pay about $150/month. Actual bills vary widely based on home size, HVAC efficiency, and season.
Yes. Duke Energy Carolinas and Duke Energy Progress both offer optional Schedule R-TOU rates with summer on-peak hours of 3–9 PM weekdays (June–September) and winter on-peak hours of 6–9 AM weekdays (December–March). Duke Energy Florida offers a limited EV time-of-use rate. Most residential customers don't save on TOU unless they have an EV, solar with battery storage, or a large dispatchable load.
The biggest wins come from reducing overall kWh consumption. HVAC accounts for 45–55% of a typical Duke Energy summer bill, so a smart thermostat like the Ecobee Premium can cut cooling costs by 15–23%. Real-time energy monitoring identifies phantom loads (dying appliances, forgotten pool pumps) that often waste 8–12% of the bill. Heat pump conversion from resistance heat can reduce winter bills by 40–60%.
