Oklahoma EV Charging Costs (2026)
Data updated: May 19, 2026
Oklahoma is a low-cost home-charging state, but the annual budget is more than the electric rate. A typical light-duty EV starts with a $110 registration surcharge, plug-in hybrids start at $82, and covered paid public charging can add the state's $0.03/kWh DRIVE Act tax. The utility account then decides the charging routine: OG&E customers can compare SmartHours options, PSO customers have a residential EV tariff with 11 p.m.-6 a.m. super off-peak pricing, and Oklahoma Electric Cooperative members have a 9 p.m.-5 a.m. EV rate. For road trips, I-35, I-40, and I-44 remain the main fast-charging corridors to check first.

| Utility | Avg Rate |
|---|---|
| Oklahoma Gas & Electric (OG&E) | Oklahoma City and central Oklahoma customers can compare SmartHours options and should verify whether any EV charger rebate form is currently open before buying equipment |
| Public Service Company of Oklahoma (PSO) | Tulsa and eastern Oklahoma customers should check PSO's residential EV rate, including 11 p.m.-6 a.m. super off-peak pricing |
| Oklahoma Electric Cooperative (OEC) | Norman-area OEC members can compare a 9 p.m.-5 a.m. EV rate and Level 2 rebate eligibility |
| Co-ops, municipal utilities, and public corridors | Local programs vary widely; paid public fast charging may also include Oklahoma's $0.03/kWh DRIVE Act tax |
Oklahoma Utility Context for EV Charging Costs
Oklahoma charging costs usually begin with cheap home electricity, then split by utility program and charging location. Home charging, utility EV rates, co-op programs, and paid public fast charging use different timing rules, fees, and tax treatment.
- OG&E says EV owners can use SmartHours Daily, SmartHours Fixed, and SmartHours Overnight options, with off-peak discounts from June 1 through September 30.
- OG&E's EV charger rebate materials list $250 per port for ENERGY STAR certified Level 2 chargers, but the available application language is tied to a 2024 purchase window; customers should confirm current rebate availability directly with OG&E before buying equipment.
- PSO's Oklahoma residential EV tariff lists a $17 monthly base service charge and a super off-peak energy charge from 11 p.m. to 6 a.m. every day. The approved 2025 tariff shows $0.030451/kWh for that super off-peak period before applicable riders and adjustments.
- The same PSO tariff defines June through October as the on-peak season, with 2 p.m.-7 p.m. weekday on-peak hours during those billing months.
- Oklahoma Electric Cooperative publishes an EV rate with 9 cents/kWh from 5 a.m. to 9 p.m. and 5 cents/kWh from 9 p.m. to 5 a.m., plus a $1.50/day service availability charge.
- OEC's rebate sheet lists a $300 electric-vehicle rebate for Level 2 charging scheduled between 9 p.m. and 5 a.m., subject to verification and funding availability.
- Oklahoma law says a non-regulated entity that provides retail EV charging services is not defined as a public utility when selling electricity for EV fueling, but utility-owned public fast charging has additional separation and subsidy rules.

Oklahoma Local EV Charging Insights
Oklahoma's charging network is strongest along the interstate triangle. Oklahoma City, Tulsa, Norman, I-35, I-40, and I-44 have more backup options than many rural routes; western, southeastern, and lake-country trips still deserve a route-level charger check.
- AFDC's 2024 vehicle data lists 22,600 EVs and 34,300 PHEVs registered in Oklahoma, plus 73,000 conventional hybrids.
- AFDC's Oklahoma state summary lists 1,661 public electric charging ports and 264 private electric charging ports.
- AFDC's public station-count table, last updated May 16, 2026, breaks Oklahoma's public electric charging into 394 station locations, 1 Level 1 port, 651 Level 2 ports, and 1,010 DC fast ports.
- AFDC lists Oklahoma's annual EV and PHEV registration fee by GVWR. The lightest tier is $110 for EVs and $82 for PHEVs at 6,000 pounds or below, rising to $2,250 and $1,687 for the heaviest tier.
- Oklahoma Tax Commission guidance says the DRIVE Act tax took effect January 1, 2024 and charges $0.03/kWh on electric fuel dispensed into an EV battery at covered paid public charging stations.
- The same Tax Commission page says the DRIVE Act tax does not apply to private-residence charging for personal use, chargers below 50 kW, charging stations that do not require payment, or certain legacy chargers until November 1, 2041.
- ODOT's first NEVI award approved more than $8 million in federal funds for 13 stations along Oklahoma interstates, with Love's, Francis Energy, and Tesla providing a combined $7 million private match.
- ODOT says those 13 stations are intended to complete EV charging corridors on I-35, I-40, and I-44, with sites within one mile of an exit, within 50 miles of preexisting or planned sites, and equipped with at least four 150 kW-capable ports.
