EV Charging in Illinois: What the Numbers Mean
Illinois's residential electricity rate is 14.9¢/kWh — 1.2¢ 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 $511/year to charge at home for 12,000 miles.
Compared to a 30 MPG gas car at $3.55/gal ($1420/year for the same miles), EV home charging saves $909/year — $4,545 over 5 years, before incentives.
Home Charging vs Public Charging in Illinois
The biggest driver of EV cost is where you charge. Home charging at 14.9¢/kWh is always the cheapest option. Public Level 2 stations average around 37.3¢/kWh — 2.5x more expensive. DC fast chargers run about 35.0¢/kWh. Tesla Superchargers in Illinois are estimated at 31.6¢–39.3¢/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 $1200/year in Illinois, narrowing the gap with gas considerably.
