EV Charging in Connecticut: What to Know
Connecticut's residential electricity rate of 27.5¢/kWh is 11.4¢ above the national average of 16.1¢/kWh. High electricity rates in Connecticut reduce the fuel savings advantage of EVs. Check whether your utility offers a time-of-use (TOU) rate for overnight EV charging, which can cut costs substantially.
At 7.2¢ per mile for home charging versus 12.3¢ per mile for a 28 MPG gas car at current Connecticut gas prices ($3.45/gallon), the per-mile gap is 5.1¢. Over 12,000 miles per year, that's $611 in favor of the EV.
Most Connecticut utilities offer time-of-use rates that can reduce overnight charging costs below the residential average. If you charge overnight (midnight to 6am), ask your utility about EV or off-peak rates. Even a few cents per kWh savings adds up to $100–$200/year for average EV drivers.
