Why the power goes out in Swansea
Swansea is the second city of Wales and the central urban network inside NGED's South Wales licence area, plus the Gower peninsula. Compact city of 240,000 on Swansea Bay, with the Gower peninsula (the UK's first AONB) extending west.
Weather and terrain. Atlantic storms hit Mumbles and Gower directly; Swansea's seafront has been progressively rewired with flood-resilient substations since 2015.
How the network is run. NGED depots at Swansea (main) and Gorseinon dispatch engineers. The University of Wales Trinity Saint David's Bay Campus has dedicated supply.
A local quirk worth knowing. The Mumbles lifeboat station and the Gower coastal villages have prioritised supplies — RNLI operations stay live through almost all weather.
What to do when the power goes out at home in Swansea
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 National Grid Electricity Distribution network fault: call 105.
Dial 105 or 0800 6783 105
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.
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.
Log start and end times
A cut over 24 hours in normal weather entitles you to £75 from National Grid Electricity Distribution 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.

National Grid Electricity Distribution 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).
