How This Study Was Built
The North Georgia EV Home Charging Cost Study relies on published utility rate data, federal vehicle efficiency figures, state EV registration records, and expert commentary from Car Charger Specialists, a licensed electrical contractor based in Oakwood, Georgia. Cost comparisons are tied to stated data sources and assumptions.
Primary Data Sources
Georgia Power
Residential EV time-of-use rates, off-peak pricing, and Level 2 charger rebate program details.
DOE Alternative Fuels Data Center (AFDC)
Georgia EV registration totals, including 85,050 vehicles in Q4 2023, and Georgia's ranking as the 8th largest U.S. EV market.
EPA FuelEconomy.gov
Fleet-average efficiency for mid-size battery electric vehicles: 28 kWh per 100 miles.
ChargeHub and Atlanta Market Data
Public Level 2 charging rates in the Atlanta metro area, modeled at approximately $0.30 per kWh.
costtocharge.com and TrendX Insights 2026
DC fast charging rate ranges used in the report, from approximately $0.40 to $0.65 per kWh.
EIA Residential Energy Consumption Survey (RECS)
Baseline residential electricity consumption benchmarks.
IRS Form 8911 (30C Credit)
Federal tax credit eligibility context for EV charging equipment.
Experian / NREL
EV ownership and mobile charger prevalence data, including the report's 80% mobile charger ownership figure.
EV Manufacturer Documentation
Tesla, GM, Hyundai, and other owner manuals and official charging recommendations for daily charging and DC fast charging use.
Time Period
Registration data reflects Q4 2023, the most recent full-quarter figure available from DOE AFDC at the time of publication. Utility rate data reflects Georgia Power published residential schedules current as of the study period. The study was published in 2026.
Analytical Approach
Annual charging energy was calculated by applying the EPA's 28 kWh per 100-mile efficiency figure to an assumed annual driving distance of 13,500 miles, producing a baseline of approximately 3,780 kWh per year. That energy figure was multiplied across five rate scenarios: super off-peak, off-peak EV rate, standard residential, public Level 2, and DC fast charge. Payback period was calculated by dividing net installation cost after the $300 Georgia Power rebate by annual savings versus public Level 2 charging.
Limitations
- Annual mileage of 13,500 miles is an approximation.
- Public charging rates reflect Atlanta-area market averages; rural North Georgia rates may differ.
- DC fast charging costs represent a range, not a single tariff. Savings figures using DC fast charging as a baseline would be materially higher than the $794 figure cited for public Level 2 comparison.
- Rebate availability for Electric Membership Cooperative customers was noted but not quantified because programs vary by cooperative.
