The scheme was conceived by the Edinburgh architects Tarbolton & Ochterlony. Following Matthew Ochterlony's death in 1946, the scheme was progressed alone by Harold Tarbolton.[1]
Construction began in May 1945, under the auspices of the North of Scotland Hydro-Electric Board and was completed in 1949. The official opening ceremony took place on 18 October 1950 and was attended by Queen Elizabeth.[2] The project claimed a new British small tunnelling record January 1951, after a distance of 278ft was bored over a period of seven days.[3]
Historic Scotland has designated the modernist power-station building and the dam as listed buildings of categories A and B respectively.[4][5]
Twenty-one men lost their lives during the construction.[6] The labour force also included some German prisoners-of-war.
The facility is operated by Scottish and Southern Energy, and is normally in standby mode, ready to generate electricity to meet sudden peaks in demand.[7] It can reach full capacity within 5 minutes from a standing start.[8]
