Activities

Field Visit (2010)

Nant is a relatively small station with an operating capacity of 15MW and was one of the last stations commissioned by NoSHEB. The station uses water from Loch Nant (see separate item for dam) which comes through a tunnel to a surge shaft above the station where additional water from other catchments is also piped in. Water then enters a pressure tunnel to reach the turbine. Nant power station is a relatively small underground station, with the powerhouse blasted from solid bedrock. It is amongst the deepest of the underground stations in Scotland. The interior of the station is predominantly standard for this type as is the large arched access tunnel portal.
