South Carolina EV Charging Costs (2026)

Home charging in South Carolina averages around $0.15/kWh. Public Level 2 sessions are estimated around $0.26-$0.39/kWh, while DC fast charging is estimated around $0.42-$0.57/kWh depending on network and membership. Final cost can also include session or idle fees.

It depends on the utility. Santee Cooper publishes EV-specific super off-peak windows, including 11 p.m.-5 a.m. on its Residential Electric Vehicle Power Schedule and 9 p.m.-5 a.m. on its EV-only rider. Dominion Energy South Carolina customers can compare the voluntary You Shift/You Save TOU plan, while Duke, co-op, and municipal customers should verify their own tariff before assuming one statewide off-peak window.

Charging a Tesla Model Y from near-empty in South Carolina costs approximately $11.39 at home, $22.77 at a public Level 2 station, and $36.43 at a DC fast charger, based on EPA efficiency of 25.3 kWh/100 miles and an estimated 300-mile range.

AFDC summarizes South Carolina law as a biennial fee of $120 for plug-in electric and fuel-cell vehicles and $60 for hybrid electric vehicles, in addition to standard registration fees. On an annualized cost basis, that is about $60/year for a plug-in electric vehicle and $30/year for a hybrid category vehicle.

No broad statewide consumer EV purchase rebate is listed in AFDC's South Carolina electricity incentives summary. The active state-level support is more project-oriented, including Energy Office grants and revolving loan programs for eligible entities, while consumer value usually comes from utility programs and home-charging rate choices.

Dominion's You Shift/You Save plan is a voluntary residential time-of-use rate that specifically lists customers with EVs they charge at home as potential fits. Dominion says super off-peak periods are about 40% cheaper than the standard Rate 8 benchmark, but on-peak usage can be more expensive and TOU periods are under SCPSC review for possible July 2026 updates.

Santee Cooper publishes two EV-oriented residential options. The Residential Electric Vehicle Power Schedule lists 4.18 cents/kWh super off-peak from 11 p.m. to 5 a.m.; the EV-only rider requires a second meter and lists 4.18 cents/kWh super off-peak from 9 p.m. to 5 a.m. Both should be checked with demand charges, equipment rules, and current riders before enrollment.

Duke Energy's EV Complete pages include South Carolina in the Charger Prep Credit workflow and describe qualifying charger-prep work such as conduit, wiring, outlets, panel upgrades, and breaker installation. The current credit amount, eligible work, contractor path, and service-territory eligibility should be verified from the customer's account before work starts.

South Carolina's 2025 EV Charging Infrastructure Deployment Plan says the state is expected to receive about $70 million in NEVI formula funding over five years and had about $55 million allocated to date. SCDOT expected to release an RFP in 2026 after the procurement pause tied to federal NEVI changes, so corridor deployment should be treated as developing rather than complete.

AFDC summarizes South Carolina law by stating that an entity operating an immobile EV charger is not considered a public utility when the electricity is procured from an authorized electric utility. Charging-site operators still need to follow applicable utility, site, payment, and operating requirements.
