Sloy Power Station

Sloy Power Station is a hydroelectric facility on Loch Sloy in the Highlands that channels water from the lake through large pipes and down the mountain slopes to drive its turbines. The modern installation consists of massive steel pipes and machine halls integrated into the mountainous terrain.

The project began in 1945 under the North of Scotland Hydro-Electric Board and was completed by 1949. The construction phase involved both German prisoners of war and local workers building the station together.

The building stands as an example of post-war modernist industrial architecture. It shows how local engineering expertise and forward-thinking design came together to serve Scotland's energy needs.

The station operates on an automated basis and processes large volumes of water flowing down from the mountain slopes. The area is rugged highland terrain and can be windy and wet, particularly during the wetter months.

The facility underwent major modernization in the 1990s when several generators were upgraded to increase power output. These works show how older infrastructure was adapted to meet changing energy demands.
