If you're interested in our hydro heritage, visit Pitlochry Dam Visitor Centre, located beside our Pitlochry Power Station in Perthshire, Scotland.

The visitor centre showcases the rich history of hydro electricity in the north of Scotland and how it transformed all our lives. On display are a number of fascinating artefacts that show how generations of homes have been transformed by electrical appliances.

Visitors will meet the visionaries, such as Tom Johnston, who saw the untapped potential of hydro power in Scotland as well as hear the stories of the Hydro Boys and Tunnel Tigers who lived – and sadly in some cases died – building the schemes.

Pitlochry’s ‘fish ladder’ was integral to the design for the hydro electricity scheme in the early 1950’s. Thousands visit the Dam to see the salmon swim to their breeding grounds up river and now everyone can learn the secrets of that incredible journey.
