Retail choice in Massachusetts
Massachusetts lets many households buy their electricity from a competitive supplier while the local utility still delivers it. Customers who buy energy from a supplier paid an average of 15.2¢/kWh for the energy alone (1,805,438 homes), plus the utility's delivery charge. Compare a supplier's offer with the utility's default price including all charges, not just the energy rate.
