Our Network

A network pylon imageAt Northern Ireland Electricity Networks (NIE Networks), we own the electricity network which is made up of thousands of kilometres of lines and cables, substations and meters.

Our network starts at substations beside power stations or wind farms and finishes at around 860,000 meter boxes across Northern Ireland.

It transports electricity from where it is made to where it is used.

The majority of the electricity network was built during the late 1960s and 1970s. This was called ‘rural electrification’.

Today, the network is still growing with every new home or business that is connected to it. We also maintain and upgrade the equipment that is already in place.

Government policies to encourage more electricity to come from renewable sources are posing new challenges. Being ready for a cleaner, greener future requires the network to be strengthened or extended in rural areas where wind farms, anaerobic digesters or tidal generators are being sited.

Staying 'smart'

Where our electricity comes from and how we use it is changing. We need to develop our networks for the future.
