Two archive films dealing with hydro-electric schemes in Scotland.

First, from 1952-56, the construction of the Glen Moriston dam by the Mitchell Construction Co. Plenty of machinery in view as well as an explanation of construction techniques and footage of underground work. B/w, with narration, 33 minutes.

The second film, Cruachan (1966), covers the construction of the ambitious pumped-storage hydro-electric scheme at Loch Awe, Argyll. The engineering detail is particularly strong, including the manufacture and finishing of steel castings, cables, circuit breakers and switch gear. Colour, fully scripted, 48 minutes.
