One of the focal points of the Cruachan visitor centre, the exhibition provides information on the past, present and future of electicity generation.

Wall-mounted photographs and placards take you through the history of Cruachan Power station. A hefty folder is available to view, containing hundreds of press clippings collected over the past five decades.

For the more technical minded, diagrams and cut-away models of the turbines and other machinery inside the hollow mountain are on display.
