What’s going on with electricity prices in Connecticut
Connecticut electricity averaged 24.51¢ per kWh in August 2026, #11 of 51. That is still well above the national average of 18.16¢, but Connecticut is one of only 7 states where home electricity got cheaper over the past year.
Connecticut’s default electricity price, called standard service, is reset twice a year, in January and July, so the average can move sharply between seasons. With prices this high, an EV still saves about $920 a year against a 30-mpg car, but the supply contract you’re on matters a lot.
