EV Charging in Connecticut: What the Numbers Mean
Connecticut's residential electricity rate is 27.5¢/kWh — 11.4¢ above the national average of 16.1¢/kWh, which narrows EV savings somewhat. At that rate, a typical EV (3.5 mi/kWh) costs $943/year to charge at home for 12,000 miles.
Compared to a 30 MPG gas car at $3.45/gal ($1380/year for the same miles), EV home charging saves $437/year — $2,185 over 5 years, before incentives.
Home Charging vs Public Charging in Connecticut
The biggest driver of EV cost is where you charge. Home charging at 27.5¢/kWh is always the cheapest option. Public Level 2 stations average around 68.8¢/kWh — 2.5x more expensive. DC fast chargers run about 38.8¢/kWh. Tesla Superchargers in Connecticut are estimated at 46.0¢–55.0¢/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 $1330/year in Connecticut, narrowing the gap with gas considerably.
