EV Charging in South Carolina

Dominion Energy South Carolina, Duke Energy Carolinas, Duke Energy Progress, and Santee Cooper each offer residential TOU rates with EV-relevant overnight discounts. Dominion's residential TOU shifts on-peak windows seasonally with a weekday afternoon and early-evening peak in summer. Duke Energy Carolinas and Duke Energy Progress both offer Residential Service Time-of-Use (RS-TOU) schedules with weekday on-peak windows that vary by season. Verify current Santee Cooper residential EV rate schedule directly with the utility.

South Carolina's two large IOUs both run net-billing successor programs under the Energy Freedom Act (Act 62 of 2019) and subsequent PSC orders. Duke Energy Carolinas and Duke Energy Progress transitioned from retail-rate net metering to Solar Choice tariffs that credit exports at time-varying rates below the full retail rate. Dominion Energy South Carolina's bridge net metering program has expired and new customers enroll in its successor Solar Choice tariff with export credits below retail. Santee Cooper, the state-owned public utility, runs its own residential solar tariff.

South Carolina has no right-to-charge statute. HOAs and condominium associations may lawfully restrict or prohibit EV charging station installation, subject only to general architectural-review obligations under the governing documents.

South Carolina charges the EV and PHEV road use fee biennially: $120 BEV / $60 PHEV every two years under S.C. Code § 56-3-645. Recorded values are the per-year equivalent.
