Network investment

At Northern Ireland Electricity (NIE), we work to five-year investment plans agreed by the Utility Regulator.

Since 2007, NIE has invested around £450 million in the electricity network in Northern Ireland.

These plans include:

Maintenance of lines, cables and substations
Upgrade of identified substations, lines and cables
Tree cutting next to overhead lines
Major projects for network expansion to meet future infrastructure needs

Our current five-year plan will complete in 2012 and we have submitted our future plan which will run from 2012 to 2017 to the Utility Regulator.
