How these rates are built
Massachusetts Electric Company territory, including Worcester, not Eversource's Boston territory. R-1 retail delivery is 22.327¢/kWh effective August 1, 2026, plus a $10 monthly customer charge. Default fixed basic service is 17.185¢/kWh from August 1, 2026 through January 31, 2027, so delivery plus fixed supply is 39.512¢/kWh. The stored range is delivery plus the variable basic-service prices for that same period, 16.074¢ in August 2026 through 20.086¢ in January 2027. Heat-pump delivery drops to 18.090¢/kWh from November through April. Taxes are extra.
EV and time-of-use notes
There is no residential time-of-use tariff. The Off-Peak Charging Program pays a rebate of 5¢/kWh from June through September and 3¢/kWh from October through May for charging from 9pm to 1pm every day. It does not change the R-1 price on the bill.
