Turlough Hill generates up to 292MW during peak demand periods by releasing water from its artifical Upper Reservoir and allowing it to flow through four Turbines into the lower Lough Nahanagan.

During periods of lower demand the water is pumped back to the Upper Reservoir ready to be used again. The station can go from standstill to full generation in 70 seconds. It is a key element of Ireland's National Grid System as it smooths peaks and troughs in electricity demand.
