40 Years at Turlough Hill
ESB celebrating 40 years at Turlough Hill
Pumped Storage power station in the heart of the Wicklow Mountains
Turlough Hill is Irelandís only pumped hydro-electric storage system. Set in the stunning Wicklow mountains this engineering marvel generates up to 292MW of electricity 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 construction of Turlough Hill over a six year period from 1968, was a hugely ambitious feat of engineering and reflects the innovative approach to delivering sustainable energy solutions that ESB retains to this day. The powerful pumped storage system at Turlough Hill means that extra electricity is available immediately unlike a conventional oil or gas generating station.
