The East Midlands Electricity Board (EMEB) was formed in 1947 as one of the United Kingdom's twelve area electricity boards specified under the Electricity Act 1947. In 1990 it was floated on the stock market as East Midlands Electricity plc, which went through several changes of ownership.

The Central Electricity Generating Board (CEGB) was responsible for electricity generation, transmission and bulk sales in England and Wales from 1958 until privatisation of the electricity industry in the 1990s.
