Distribution Network Operator

From Wikipedia, the free encyclopedia

Distribution Network Operators (DNOs) are companies licensed 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 are also responsible for allocating the core MPAN in the respective areas. Under the Utilities Act 2000 they are prevented from supplying electricity; this is done by a separate company chosen by the consumer who makes use of the distribution network.

In 1990, the Area Boards were replaced by Regional Electricity Companies, which were then privatised. The DNOs are the successors to the distribution arms of the RECs.

As of June 2006, nine companies hold the fourteen distribution licences:
