Massachusetts allows customers of NStar, National Grid, Fitchburg Gas & Electric, Unitil, and Western Massachusetts Electric to choose alternative electric suppliers. The utilities sold their power plants and now only own the transmission and distribution wires. Customers who do not choose an alternate energy provider receive “basic supply service” from the utility. Rates for basic service are set via competitive bidding and adjusted frequently based on a customer's class. Basic service prices for large and medium business customers change monthly.
Massachusetts allows all customers to choose a different company to supply them with their gas supply. Gas supply is still delivered by the local utility. Customers that do not opt for an alternate gas supplier receive default supply service from their utility called “cost of gas” which can vary as often as monthly.
