Northern Ireland Electricity (NIE) is the transmission and distribution (T&D) company with responsibility for the carrying of electricity from generators to customers within Northern Ireland.
It also has cross-border links which help to facilitate the Single Electricity Market and receives (and sends) electricity from the Moyle Interconnector, linking to Scotland.
Until December 2010, NIE was a wholly owned subsidiary in the Viridian Group. It was sold for a reported £1.2bn to become a wholly owned subsidiary of ESBNI, the Northern Ireland part of the Irish ESB . The change in ownership of NIE further contracted the original Viridian group, leaving what is now called Power NI as the largest local electricity supply company which is still in the Viridian Group.
NIE is a regulated monopoly for T&D.
