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.

[2] 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.

This innovative plan, which faced significant scepticism initially, was considered to be at the forefront of technology which challenged designers and overseas manufacturers.

Tumut 2 Power Station is situated approximately 5.91 kilometres (3.67 mi) north of north-west from Cabramurra, under Goat Ridge Rd, some 244 metres (801 ft) below ground level.

[8] Pump-storage schemes use off-peak energy to pump water to a reservoir on a higher level.

These GreenPower accredited units enable Snowy Hydro to save approximately 3,137 tonnes (3,458 short tons) of carbon dioxide per annum.
