Where Duke offers TOU vs TOU-Demand
Duke serves North and South Carolina with the DAC
. TOU with Demand (R-TOUD) is available in parts of the Carolinas; other states generally offer energy-only TOU variants (e.g., Flex Savings), not residential demand charges. Always confirm details under your state menu.
- Two demand measures:
- an on-peak billing demand (highest 15-min kW inside the on-peak window) and sometimes a maximum billing demand (highest 15-min kW during any hour of the month). Customers must limit brief overlaps. (Availability & specifics vary by Duke Carolinas company/tariff.) (Duke Energy)
Recent & upcoming changes
- NC: 2024–2025 rider/fuel adjustments led to decreases for typical residential customers (e.g., 4.5% down for Duke Energy Progress in NC as of Dec 1, 2024; DEC down 6.2% Jan 1, 2025). Expect routine annual fuel updates.

- Savings: 8–20% with strict concurrency control; higher if EV/water-heat shift into deep off-peak/discount windows (where offered).
