Turlough Hill is Ireland's only pumped storage station, It generates up to 292MW during peak demand periods by releasing water from its upper reservoir and allowing it to flow through its four turbines into a lower reservoir. During periods of lower demand the water is pumped back to the upper reservoir ready to be used again.
The station is located approximately 60km south of Dublin City in the Wicklow Mountains. Construction commenced in 1968, and the station became fully operational in 1974. During 2004, Turlough Hill became the Hydro Control Centre (HCC) for the entire ESB hydro fleet which contains 19 generators in total.
The three hydro generation stations on the Liffey are also part of Turlough Hill Stations. See Liffey Stations for more details.
