About
Dinorwig Power Station at Llanberis [9] — Tours of this power station are, despite the somewhat outdated multimedia presentation at the beginning, a must see. A huge cavern was carved out of the mountain and six turbines installed which sit in tunnels between two lakes, one high up, the other at close to sea level. When Britain switches on the kettle during the advert break in Coronation Street, water is released from the upper lake and the most expensive electricity in Britain is generated to cope with demand. Later at night, when demand is low and electricity is cheaper, water is pumped back up to the top lake from the lower one. Wheelchairs are exceptionally well catered for and the cafe is not a bad place to stop in whilst waiting for the tour to begin.
