Duke Energy Florida

Duke Energy Florida offers a residential time-of-use rate that EV owners can use to shift home charging out of peak hours. Weekday on-peak runs 6pm to 9pm year-round, with an added winter on-peak window from 5am to 10am from December through February. A lower-priced discount period runs midnight to 6am every day March through November and midnight to 3am December through February, which suits overnight charging. Everything else, including weekends and the excluded holidays, is off-peak. Specific cents per kilowatt-hour change with fuel cost adjustments and are listed in Duke's filed tariff schedules, so check the current rate sheet before assuming a number for your bill.

The time-of-use rate and the Off-Peak Charging Credit are alternatives, not a stack: the credit is open only to customers on Duke's standard, load-management, or FixedBill residential rates, not the whole-house time-of-use rate. The credit pays $7.50 per month per EV, for up to two EVs, to residential customers with a Level 2 charger who charge during off-peak windows of 10am to 6pm and 11pm to 5am weekdays plus anytime on weekends and holidays. The Charger Prep Credit is separate from either rate choice and reimburses make-ready electrical work for residential or business customers installing Level 2 or higher chargers; the charger hardware itself is not covered. Commercial credits vary by charger type, total kW, and whether service upgrades are needed; Duke's commercial Charger Prep Credit page, set to Florida, shows the current credit for each configuration.

Duke Energy Florida is a Florida Public Service Commission regulated investor-owned utility, so program scope is set through PSC-approved agreements and tariffs rather than by Duke alone. That matters in practice: the 627-station Park and Plug public charging pilot launched in 2018 under an agreement with the PSC and closed when the buildout was complete. The 2025 Charger Prep Credit, Off-Peak Charging Credit, and Fleet Advisory programs replaced it as the active EV portfolio.
