Incorporated in January 1886 as the Edison Electric Illumination Company of Boston, the Boston Edison Company was among the earliest American electric utility companies. Between 1901 and 1912, the company absorbed nineteen Boston area electric companies. In 1902, it merged with its chief competitor, the Boston Electric Light Company, and became the dominant provider of electrical power for greater Boston. The Edison Electric Illumination Company (EEIC) of Boston was renamed the Boston Edison Company in July 1937. From its founding, the Boston Edison Company pioneered numerous electrical industry innovations. These included its early efforts to create an underground wiring network, its groundbreaking use of high-pressure steam turbine generators in the I 920s, and its pollution control projects, which began in the 1930s.

NSTAR was formed in 1999 by the merger of BEC Energy and Commonwealth Energy System and currently has the following operating units: Boston Edison Company, Cambridge Electric Light Company, Commonwealth Electric Company, and NSTAR Gas Company (formerly Commonwealth Gas and Cambridge Gas Company). In October 2010, Northeast Utilities and NSTAR announced they would merge, with the resulting company retaining the Northeast Utilities name.
