From Lamont's press release.

As of January 1, 2023, Connecticut’s all-in residential electric rates ($0.35/kWh) for both Eversource and UI will be within the same range as most New England utilities, including New Hampshire ($0.33/kWh to $0.39/kWh) and Rhode Island ($0.29/kWh). Only Maine ($0.24/kWh to $0.28/kWh) and Vermont* ($0.18/kWh) are lower. Meanwhile, customers of National Grid and Unitil in Massachusetts are paying over 40% higher rates than Connecticut at $0.48/kWh and $0.42/kwh (Note: Electric rates change seasonally and on different timeframes for each utility; these figures are subject to change).
