Northern Ireland Electricity

Northern Ireland Electricity is responsible for the planning, development, construction and maintenance of the transmission and distribution network, and for the operation of the distribution network.

The electricity grid comprises a number of interconnected networks of overhead line and underground cables, which are used for the transfer of electricity to customers via a number of substations. There are approximately 2,100km of transmission network, of which some 80km are underground, and approximately 42,900km of the distribution system, of which some 13,100km are underground. There are currently over 790,000 customers connected to the distribution system.

One of our main responsibilities is to ensure the communities which we serve have a safe and reliable supply of electricity, and that we do everything we can to restore supplies as safely and quickly as possible following interruptions.
