About electricity rates in Massachusetts
Massachusetts restructured its market decades ago, so households served by Eversource, National Grid or Unitil may buy their supply from a competitive supplier, join a municipal aggregation in which their town negotiates supply for all residents, or stay on the utility's basic service. Dozens of municipal light plants run their own systems outside this structure. The Department of Public Utilities regulates the investor-owned utilities.
The state is part of the ISO New England grid, where natural gas provides most of the generation, with offshore wind and solar growing and the last in-state nuclear plant now closed. Cold winters are heated mostly with gas and oil, though heat pumps are promoted through utility programs, and summers bring air-conditioning peaks. Energy efficiency programs funded through a charge on bills are extensive, and a state incentive program supports rooftop and community solar alongside net metering.
