Cru­achan facts

Argyllshire Advertiser - - NEWS -

At its peak, around 4,000 peo­ple worked on the con­struc­tion project. 36 men died build­ing the power sta­tion and dam. The scheme cost £24.5 mil­lion. Cru­achan is one of four pumped stor­age schemes in the UK. The power sta­tion was orig­i­nally op­er­ated by the North of Scot­land Hy­dro-Elec­tric Board, be­fore trans­fer­ring to the South of Scot­land Elec­tric­ity Board, now Scot­tish Power. Just last week Cru­achan was pur­chased by Drax Group as part of a £702 mil­lion ac­qui­si­tion of Scot­tish Power as­sets. The up­per reser­voir sits 396 me­tres (1,299 ft) above Loch Awe. The sta­tion is ca­pa­ble of gen­er­at­ing 440 megawatts of elec­tric­ity from four tur­bines and can go from standby to full pro­duc­tion in two min­utes, or 30 sec­onds if com­pressed air is used to start the tur­bines spin­ning. When the top reser­voir is full, Cru­achan can op­er­ate for 22 hours be­fore the sup­ply of wa­ter is ex­hausted.
