Distribution network operator
Appearance
Distribution Network Operators (DNOs) are companies licenced to distribute electricity in Great Britain by the Office of Gas and Electricity Markets.
There are fourteen regions, based on the former Area Electricity Board boundaries. In each area the DNO enjoys a monopoly on distributing electricity from the transmission grid to homes and businesses. They do not supply electricity: this is done by a seperate company chosen by the consumer who makes use of the distribution network. Under the Utilities Act 2000 it is unlawful for the same company to both distribute and supply electricity in an area.
