Field Visit (2010)

Glenmorriston Power Station is the bottom station on the cascade development forming the northern part of the Great Glen scheme. The station is situated deep underground beneath the downstream face of Dundreggan Dam (see separate item). It was amongst the first underground stations to be commissioned by the board. The station has a capacity of 36MW, the turbines and turbine hall were fully refurbished in 1999. Glenmoriston Power Station is a good example of the early use of underground stations developed by NoSHEB from around 1956 onwards. The Great Glen scheme is characterised by the use of underground stations with other examples including Ceannacroc and Livishie. The design of subterranean stations was pioneering for this date with most developments using surface stations and steel penstocks for the pressure system.
