EV Charging in Kentucky: What the Numbers Mean
Kentucky's residential electricity rate is 11.8¢/kWh — 4.3¢ below the national average of 16.1¢/kWh, which works in EV owners' favor. At that rate, a typical EV (3.5 mi/kWh) costs $405/year to charge at home for 12,000 miles.
Compared to a 30 MPG gas car at $3.05/gal ($1220/year for the same miles), EV home charging saves $815/year — $4,075 over 5 years, before incentives.
Home Charging vs Public Charging in Kentucky
The biggest driver of EV cost is where you charge. Home charging at 11.8¢/kWh is always the cheapest option. Public Level 2 stations average around 29.5¢/kWh — 2.5x more expensive. DC fast chargers run about 34.0¢/kWh. Tesla Superchargers in Kentucky are estimated at 25.8¢–32.1¢/kWh depending on membership.
Most EV owners do 80%+ of their charging at home overnight. If you don't have home charging access, the economics shift significantly — charging entirely at public DC fast chargers would cost $1166/year in Kentucky, narrowing the gap with gas considerably.
