Because these rates are charged per kWh, the actual impact to your bill depends on how much electricity you use. Typical residential customers on the Basic Service Rate use about 550 kilowatt-hours (kWh) of electricity per month.
Based on this usage, you would see a monthly increase of $12.51. This accounts for an average increase of $9.28 in the supply and $3.23 in the delivery portion of your bill.
Why does the electric supply rate increase in the winter?
Each year on January 1 and July 1, the purchase price of the energy we buy on your behalf from electric suppliers changes as demand for energy increases or decreases. This rate is called the Basic Service Supply rate. It represents the actual cost we pay for electricity from suppliers. The cost is passed directly through to you — with no profit to Eversource.
As the temperature drops in the winter, natural gas demand increases to heat our homes. Natural gas is also used to generate more than 50% of our region's electric energy, so the demand impacts electric supply prices, too.
