Duke Energy Progress

Duke Energy Progress publishes a Residential Service Time-of-Use rate that any residential customer can opt into, with the same seasonal structure Duke uses across its Carolinas operating companies: summer on-peak runs 6 to 9 pm May through September, winter on-peak runs 6 to 9 am October through April, and discount-rate windows sit at 1 to 3 am and 11 am to 4 pm October through April, and at 1 to 6 am May through September. Off-peak hours cover everything else plus weekends and holidays, which is when most residential EV owners charge.

The Charger Prep Credit pays for the electrical work needed to support a Level 2 charger (panel upgrades, wiring, outlet, conduit) but not the charger itself, and Duke runs separate residential and commercial tracks so a homeowner application does not block a later workplace or multifamily application at a different site. The credit stacks with the time-of-use rate: enrolling in one does not require or exclude the other. South Carolina residential customers are also eligible under a cap the PSCSC approves separately; Duke's Charger Prep Credit portal shows the current SC amount.

Two service-territory facts matter in practice. First, DEP and Duke Energy Carolinas are jurisdictionally separate utilities with separate tariff books, so rates and program caps do not automatically match even when the program name is identical. Second, the EV Complete Home Charging Plan pilot, a flat $24.99 per month for up to 800 kWh of managed home charging, was North Carolina only and closed to new enrollment in January 2024; Duke has not announced a reopening, and SC customers were never eligible.
