Live outage map for Gwynedd
The map shows incidents reported by users in real time, centred on Gwynedd. Zoom in on your street to check whether a cut is your home only or a wider network fault — when neighbours are also dark, it is a SP Energy Networks job.
Snowdonia massif in the centre, the Lleyn Peninsula in the west, and the Cardigan Bay coast in the south. Atlantic storms break over Snowdonia first — Storm Babet (2023) caused multi-day outages in the Conwy valley and along the Cambrian coast.

Why the power goes out in Gwynedd
Gwynedd is the largest Welsh county by area and contains most of Snowdonia National Park. SP Energy Networks (Manweb) covers the entire county. Snowdonia massif in the centre, the Lleyn Peninsula in the west, and the Cardigan Bay coast in the south.
Weather and terrain. Atlantic storms break over Snowdonia first — Storm Babet (2023) caused multi-day outages in the Conwy valley and along the Cambrian coast.
How the network is run. SP Manweb depots at Bangor, Caernarfon and Porthmadog dispatch engineers. Many Snowdonia villages (Beddgelert, Bethesda, Penrhyndeudraeth) sit at the end of long single-feeder spurs.
A local quirk worth knowing. The Snowdon Mountain Railway, the Ffestiniog Railway and the Welsh Highland Railway all have dedicated supplies — public-network outages do not affect heritage railway operations.
What to do when the power goes out at home in Gwynedd
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 SP Energy Networks network fault: call 105.
Dial 105 or 0800 001 5400
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 SP Energy 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 Gwynedd receive £75 after 24 hours off in normal weather, plus £40 every additional 12 hours up to £300. Severe-weather events have higher thresholds and a £2,000 cap. Payment is normally automatic from SP Energy Networks within 10 working days — claim within 30 days if it doesn't arrive.
SP Energy 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).
