Tummel hydro-electric power scheme

The Tummel hydro-electric power scheme for the generation of hydro-electric power is located in the Grampian Mountains, between Loch Ericht, Loch Rannoch and Loch Tummel, in Perth and Kinross, Scotland.

Pitlochry hydro-electric power station and River Tummel.

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, works beginning in 1947. Tarbolton died before the project was completed.[1]

As of 2019 the scheme consists of nine power stations and water, depending on where it originates and the path it takes, may pass through as many as five of them in sequence. The Power Stations are: Cuaich, Loch Ericht, Loch Rannoch, River Gaur, Tummel Bridge, Errochty, Trinafour, Clunie and Pitlochry.[2] The stations are named for their physical location as opposed to their feedstock. For example, Loch Ericht Power Station is fed from Loch Garry but is adjacent to and discharges into Loch Ericht.
