Ardnacrusha Hydro-Electric Station Tour (Heritage Week)

What to Expect

The Ardnacrusha hydro-electric station on the River Shannon opened in 1929 as one of the most ambitious engineering projects ever undertaken in the new Irish Free State, built to electrify the country. During Heritage Week 2026, ESB opens the station for free 90-minute guided tours for groups of up to 30 people. Visitors tour the headrace canal, locks and tailrace before entering the station itself to see the turbine hall and the original 1920s control room, brought to life through on-site animations. High-visibility jackets, safety hats and safety glasses are provided and must be worn throughout.
