Until recently residents of the remote Nedd Valley in the Brecon Beacons had no mains electricity – the last community in England and Wales without it.
(Nedd Valley was known even to the locals as the “place time forgot”. They survived on the unreliable power supplied by generators and the flickering light of candles and lamps. Almost three miles of power line was built over the hills from the village of Ystradfellte. Welcome to the 21st century guys!)
