Scope and Content Strathfarrar Works Contract 101, Deanie Tunnel, start of low pressure tunnel lining at intake, 3 April 1961 Hydro-electric power stations like Deanie (commissioned in 1963) use the power of flowing water released from reservoirs to drive turbines, which then turn generators to convert it into electrical energy. The power of gravity ensures that water passing downhill can be used by several power stations before it reaches the sea. The entrance to Deanie tunnel at the Loch Monar end of the tunnel shown here with the concrete lining in place. The railway was used to take concrete into the tunnel to form the lining. The intake tower and gates were built on to the rock face seen here. Deanie Tunnel is part of the Strathfarrar scheme which has four power stations, five dams and two lengthy tunnels. The Strathfarrar scheme formed part of the larger Affric/Beauly scheme that was one of eight large schemes built by the North of Scotland Hydro-Electric Board during the 1940s to 1960s.
