Why the power goes out in Derry City and Strabane

Derry City and Strabane covers Northern Ireland's second city and the western border country towards Donegal. NIE Networks runs the entire network. Foyle valley running through Derry, the Sperrin Mountains fringe in the east, and the border country in the west.

Weather and terrain. Atlantic storms hit the Donegal-side coast and reach Derry through the Foyle valley; Sperrin storms bring overhead-line damage in winter.

How the network is run. NIE Networks operates from Derry and Strabane depots. The Coolkeeragh power station near Derry is one of the largest in Northern Ireland.

A local quirk worth knowing. Derry's walled-city heritage network has been progressively re-cabled since the 2000s — the Bogside, Creggan and Waterside areas now have more robust supply than they did in the 1990s.

Derry City and Strabane is served by NIE Networks. All network faults — whoever supplies your electricity (Octopus, British Gas, EDF, OVO, E.ON Next…) — are reported on 03457 643 643. Your supplier handles the bill but cannot dispatch an engineer.

What to do when the power goes out at home in Derry City and Strabane

1

Check whether neighbours are affected

Look at the street lights and the houses opposite. If they're on, your fault is inside your home — check the consumer unit. If they're out too, it is a NIE Networks network fault: call 03457 643 643.

2

Dial 03457 643 643

Have your full postcode ready. Ask the operator for an estimated time of restoration (ETR) and a fault reference number — both make any later compensation claim faster.

3

Unplug sensitive electronics

Unplug TVs, routers, computers and consoles to protect them from a surge when supply returns. Leave one light switched on so you'll know visually when the power is back.

4

Log start and end times

A cut over 24 hours in normal weather entitles you to £75 from NIE Networks under Ofgem's Guaranteed Standards. Severe weather has higher thresholds and a £2,000 cap. Keep a written log with photos — most payments arrive automatically within 10 working days.

Yes. Under Ofgem's Guaranteed Standards of Performance, domestic customers in Derry City and Strabane receive £75 after 24 hours off in normal weather, plus £40 every additional 12 hours up to £300.

NIE Networks announces planned cuts by letter (and increasingly text or email) 2 to 8 days in advance. Most run 8am to 6pm and last 2 to 8 hours. Planned cuts do not qualify for Ofgem compensation unless your DNO failed to give adequate notice (a £40 payment applies then).
