Ffestiniog


Ffestiniog Power Station was opened on 10th August 1963 by Her Majesty the Queen. The station was one of the first pumped hydro-electric systems in the UK. Ffestiniog can be brought on-line very quickly to cope with peaks in electricity demand. The upper reservoir at Llyn Stwlan creates a head of water which flows through large diameter pipes to the turbines much further down the mountain. During off-peak times, the water is pumped back up to the Stwlan Dam.
