Why the power goes out in Carmarthenshire
Carmarthenshire is the largest council in South Wales by area, covering the Towy valley and the long Carmarthen Bay coastline. NGED's South Wales licence covers the entire county. Towy valley running south from the Cambrian Mountains, Carmarthen Bay coast, and the Black Mountain in the east.
Weather and terrain. Atlantic storms hit Carmarthen Bay; Towy flooding submerges low-lying substations at Carmarthen and Llandeilo.
How the network is run. NGED depots at Carmarthen and Llanelli dispatch engineers. Many rural villages (Llanddewi Brefi-side, Llandovery hinterland) sit on long single-feeder spurs.
A local quirk worth knowing. Llanelli's Millennium Coastal Park (former steelworks site) has been progressively recabled — the area's outage rate has dropped sharply since 2015.
What to do when the power goes out at home in Carmarthenshire
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.
