Public electricity suppliers
|This article does not cite any references or sources. (December 2010)|
Public electricity suppliers (PES) were the fourteen companies created when the electricity market in the United Kingdom was privatised. In England and Wales the Central Electricity Generating Board was responsible for the generation and transmission of electricity, with the 12 area electricity boards (AEB), formed under the Electricity Act 1947 being responsible for the distribution and supply of electricity to consumers. In Scotland the structure was different with all aspects of generation, transmission, distribution and supply being carried out by two vertically integrated companies.

On 31 March 1990 as part of the privatisation of the electricity system in England and Wales the area electric boards were changed into independent regional electricity companies (RECs) and the CEGB was split into four companies, three generation companies and National Grid Company, operator of the National Grid. The National Grid Company was placed under the ownership of the RECs. On 11 December 1990 the RECs were privatised. In 1991, the vertically integrated Scottish boards were mainly privatised whole, with the exception of their nuclear plants which were passed to Scottish Nuclear, and later privatised as part of British Energy.
In 2000, as part of further restructuring of the market under the Utilities Act 2000, the public electricity suppliers were required to have separate licenses for their supply business and distribution networks, which were renamed as distribution network operators (DNOs).
