How Deregulated Electricity Works in Massachusetts
Massachusetts deregulated its electricity market in 1997. The system operates with three components: power companies generate electricity (generation), utilities maintain high-voltage lines (transmission), and your local utility (NSTAR Electric Company, Massachusetts Electric Co, Fitchburg Gas & Elec Light Co, Nantucket Electric Co) delivers electricity to your home (distribution).
You can choose your electricity supplier from 53 competing providers. If you don't select a supplier, you automatically receive default service through your utility at a regulated rate.
