Eversource has one residential plan modeled here. A typical Massachusetts home using 602 kWh a month pays about $226 a month.
Massachusetts has retail choice. Prices on this page are all-in: Eversource’s delivery charges plus its default supply (the rate you pay if you have not chosen a supplier, often called the “price to compare”). If you buy supply from a retail supplier, Eversource still bills delivery and the supplier’s price replaces the supply part, so the supply rate alone is well below the all-in price shown here.
