Cool place. One wonders where all the water comes from as there doesn't seem to be all that much higher ground...
Have you seen how much it rains here in North Wales???
Na, just kidding - well not about the rain that's not what's filling the reservoir by it's own - it's a pumped power station reservoir.
From Wikipedia:
The Ffestiniog Power Station is a 360-megawatt (MW) pumped-storage hydroelectricity scheme near Ffestiniog, in Gwynedd, north-west Wales. The power station at the lower reservoir has four water turbines, which can generate at full capacity within 60 seconds of the need arising. The scheme has a storage capacity of around 1.44 GWh (5.2 TJ) at maximum output for four hours, and the capacity to power the whole of North Wales for several hours.
The station, commissioned in 1963, was the first major pumped storage system in the UK.The upper reservoir is Llyn Stwlan, 170,000 cubic metres (6,000,000 cu ft), which discharges 27 cubic metres per second (950 cu ft/s) of water to the turbine generators at the power station on the bank of Tanygrisiau reservoir. The building of the lower reservoir increased the size of Llyn Ystradau and flooded the route of the Ffestiniog Railway which had to build a deviation around the reservoir and power station. |
