Why the power goes out in Blaenau Gwent
Blaenau Gwent is one of the South Wales Valleys' smaller councils, with Ebbw Vale at its heart. NGED's South Wales licence covers the entire area. Steep-sided Heads of the Valleys terrain at the southern edge of the Brecon Beacons.
Weather and terrain. Atlantic storms barrelling up the Bristol Channel hit the Heads of the Valleys; freezing rain and ice on the Heads of the Valleys road (A465) take overhead lines out in winter.
How the network is run. NGED operates from a Tredegar depot. The former steelworks at Ebbw Vale has been progressively redeveloped with new feeder reinforcement.
A local quirk worth knowing. The Heads of the Valleys road (A465) regeneration has driven major feeder upgrades since 2018 — Tredegar and Ebbw Vale now have more robust supply than they had in the 1990s.
What to do when the power goes out at home in Blaenau Gwent
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.
