Construction

The Golden Falls hydroelectric plant is located downstream of the larger Pollaphuca hydroelectric power station as part of the River Liffey Scheme. The concrete dam is 98 m (320 ft) long is fitted with three gates, each of which is 7 m (23 ft) wide. The dam has an average head of 17.4 m (57 ft).[1] The dam creates a balancing reservoir between the plant and the larger one upstream and has helped to reduce the risk of flooding in Leixlip and Dublin.[2]

Generating capacity

The plant consists of a single turbine rated at 4 MW (5,400 hp) manufactured by English Electric. It spins at 187.5 r.p.m. and feeds a 5,000 kVA English Electric three phase alternator running at 10.5 kV. The average output for the station is 9 GWh a year.[1]

Archaeological importance

The Bronze Age Bishopsland Hoard was excavated during the construction of the dam in 1942 and subsequently other archaeological finds from periods back to the Neolithic have been found in the area.[3]
