Guthega Power Station is located in the Snowy Mountains region of New South Wales, Australia. The power station's purpose is for the generation of electricity. It is the first to be completed and smallest of the initial seven hydroelectric power stations that comprise the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro.

This station is connected to the National Electricity Market via the TransGrid 330/132 kV Substation at the TransGrid 330 kV Murray Switching Station, 1.56 kilometres (1.71 mi) South East of Khancoban.

Location and features

Guthega power station is located at the confluence of the Munyang River and the Snowy River, approximately Script error: No such module "convert". downstream of the Guthega Dam wall. It is a conventional hydroelectric power station, situated above ground. The waters held in the reservoir behind Guthega dam pass through a concrete lined tunnel, a surge tank and firstly one, then two steel penstocks to the power station to generate electricity.

The powerhouse is a concrete structure with a machine hall that is Script error: No such module "convert". long, Script error: No such module "convert". wide, and Script error: No such module "convert". high. Approximately Script error: No such module "convert". of concrete was used in its construction which commenced in November 1951 and was completed in April 1955.

The power station has two Francis turbines each driving an English Electric generator. The power station includes foundations for a third unit but this was never installed as there was insufficient water to make it worthwhile. The power station has a rated hydraulic head of Script error: No such module "convert".. Each turbine runs at 428 rpm and water flows through it at the rate of Script error: No such module "convert".. The total installed generating capacity is Script error: No such module "convert". of electricity yielding a net generation of Script error: No such module "convert". annually.[1][2][3]

The Guthega Power Station is the highest power station in Australia.
