Tummel hydro-electric power scheme, Hydroelectric power network in Grampian Mountains, Scotland
The Tummel scheme is a network of nine power stations distributed across the Grampian Mountains in Scotland, using water from several connected lochs. The system joins natural water sources through dams and channels to generate electricity for central Scotland's power supply.
Legislation in 1922 authorized the use of water from local lochs for electricity generation in the region. The power stations and their connecting infrastructure were then developed gradually from the 1920s through the 1950s.
The structures reflect industrial design choices from the early 20th century and show how engineering projects were integrated into the Highland landscape. Visitors can observe how these facilities became part of local identity and continue to shape how people experience the water and land.
The individual power stations are located at different points throughout the system, so you can visit multiple sites to see the scheme. Having transport helps as the stations are spread across a wide mountain area with considerable distance between locations.
The Pitlochry dam includes a fish ladder that allows salmon to swim upstream to their spawning grounds past the barrier. This shows how an industrial facility was designed with consideration for the needs of migrating fish.
