Tours at Ardnacrusha Power Station 

Would you like to visit Ireland's largest river hydroelectric scheme? After last year's response to the tours which marked ESB's 90th anniversary, we are once again inviting the public to visit and explore one of Ireland's greatest engineering developments at Ardnacrusha Power Station in Co Clare. 


As part of the Shannon hydro-electric scheme, Ardnascrusha took just four years (1925 to 1929) and 5,000 workers to build. Costing more than IR£5m to construct at the time - almost one-fifth of the entire annual budget - Ardnacrusha became a symbol of forward thinking in relation to harnessing Ireland’s natural resources. With the national grid constructed at the same time, the 86 MW capacity was then enough to meet the electricity demands of the whole country. Today, Ardnacrusha represents around 2% of our total installed capacity.

How electricity is generated at Turlough Hill

Turlough Hill, Ireland's only pumped storage power station, is located 60kms south of Dublin in the Wicklow Mountains. The station generates up to 292MW during peak demand periods by releasing water from it's upper reservoir and allowing it to flow through four turbines to the lower Lough Nahanagan. During periods of lower demand the water is pumped back to the upper reservoir ready to be used again.
