Tumut Hydroelectric Power Station /ˈtjuːmət/ is a series of three hydroelectric power stations on the Tumut River in New South Wales, Australia, that are part of the Snowy Mountains Scheme.
The generating assets of the three Tumut power stations are owned by Snowy Hydro Limited, a company whose shareholders include the governments of Australia, New South Wales, and Victoria. The company is also licensed to manage the water rights used by the power stations.
Located downstream of Tumut Pond Dam and 366 metres (1,201 ft) below ground level,Tumut 1 Power Station is situated approximately 3 kilometres (1.9 mi) south-east of Cabramurra. The conventional hydroelectric power station has four turbine generators, with a generating capacity of 330 megawatts (440,000 hp) of electricity; and a net generation of 847 gigawatt-hours (3,050 TJ) per annum. The power station was completed in 1959, and has 292.6 metres (960 ft) rated head.
The first 330 kV transmission lines were commissioned in New South Wales at the Tumut 1 Power Station during the 1950s. These cables were manufactured in England and linked to the underground transformers at Tumut 1, and connected with the transmission line. The lines carried power to Sydney where new sub-stations were established, to handle the upgrade from 132 kV transmission lines. This innovative plan, which faced significant scepticism initially, was considered to be at the forefront of technology which challenged designers and overseas manufacturers. Extra high voltage was in its infancy in the early 1950s. The lines were subject to a 1000 kV test on the cables prior to them going into service. These cables and the transmission system have been in service for over 50 years.
