Tummel Power Station [NAT]

OS 1:10,000 map, 1992.

Power Station, Tummel Bridge, 1933. Muscular inter-war classicism, painted bright white. Built for the Scottish Power Company as part of the Tummel Valley hydro-electric scheme, the station, fed by a catchment area of 381 square miles, gathered into Loch Rannoch and a smaller reservoir at Dunalastair, and delivered from an aqueduct. Two generating sets, producing a total of 34mW, are unusual in that each turbine has two horizontal runnes and spiral casings.

Activities

Note (2010)

This powerhouse utilises water from the Dunalasatir dam (see separate record) which is brought by aqueduct and pipeline to the station some 3 miles from the dam. The powerhouse contains the original two Francis turbines which are in a vertical orientation and are undershot. The powerhouse also contains the original control and monitoring systems. This is a highly significant example of the use of Hydro for large scale public supply, with the capacity for baseload generation. The classical design of the exterior of the building makes the powerhouse a prominent feature of the landscape, with original features such as control panels and turbines retained to the interior. Tummel Bridge is one of a pair of powerhouses in the scheme of similar design (see Rannoch Station). The Rannoch / Tummel scheme is distinct from the Falls of Clyde scheme (which predates it) because it uses different technology as a reservoir scheme instead of a run-of-the-river development.
