Before 1990, both the generation and transmission activities in England and Wales were under the responsibility of Central Electricity Generating Board (CEGB). The present electricity market in the UK was built upon the breakup of the CEGB into four separate companies in the 1990s. Its generation (or upstream) activities were transferred to three generating companies—PowerGen, National Power, and Nuclear Electric (later British Energy, eventually EDF Energy)—and its transmission (or downstream) activities to the National Grid Company.
In 1990, the transmission activities of the CEGB were transferred to the National Grid Company plc, which was owned by the 12 regional electricity companies (RECs) through a holding company, National Grid Group plc. The company was first listed on the in 1995.
