What drives electricity prices in Massachusetts
Massachusetts has some of the highest electricity prices in the country. It produces less than half the electricity it uses, and most of what it does produce comes from natural gas. New England sits at the end of the country's gas pipelines, and in cold weather the same limited pipeline space is needed for home heating, so gas and power prices can spike in winter.
Homes that do not choose a supplier buy basic service from Eversource or National Grid, whose price resets twice a year, in February and August. Many cities and towns buy power for residents through municipal aggregation, and dozens of communities have their own municipal light plants, which set their own rates.
Bills also fund the state's Mass Save efficiency programs and clean-energy contracts. Massachusetts homes use less electricity than homes in most states, which keeps bills from rising as far as the price alone would suggest.
