The generator operates on compensation water fed into the river Gaur, west of Loch Rannoch, to maintain the river's water level. It was installed by the Grampian Electricity Company into the neighbouring Tummel power station during its construction in 1928, before it was transferred to Gaur in 1953.
'The refurbishment of Gaur is part of a US$386M programme to refurbish our hydro resources in the north of Scotland,' said Tummel Valley Scheme operations manager Roger Twigg. 'It will bring about the replacement of engineering equipment that has served us extremely well. The compensation generator at Gaur has been in operation in the Tummel Valley since 1928, which is a tribute to the engineers who manufactured it.'
