Beginning in March 1998 all Massachusetts consumers; residential, commercial, and industrial, could choose to buy electricity from a competitive retail supplier or continue to receive generation from their distribution company called Basic/Default Service. The delivery of electricity remained with the distribution companies.  The split of services is called Electric Deregulation or Restructuring.
