The Turlough Hill pumped-storage hydroelectricity plant is opening for public tours during Summer 2014, to mark the 40th anniversary of the commissioning of the station, which is located in the Wicklow Mountains near Glendalough.
The Turlough Hill plant began construction in 1968 and was completed 6 years later. It is owned and operated by ESB. The main station is buried inside the mountain and can generate up to 292 MW of electricity at times of peak demand. It can also go from standstill to full capacity in only 70 seconds.
Guided tours are available every Tuesday to Friday during June, July and August and select Saturdays and Sundays. Places can be reserved for these tours at www.esb.ie/turloughhill and more information can be found here.
