<h1>Tumut 3 Power Station</h1>

<h3>Tumut 3 Power Station is the first <a title="Pumped-storage hydroelectricity" href="https://en.wikipedia.org/wiki/Pumped-storage_hydroelectricity">pumped storage hydroelectric</a> power station in Australia.<a href="https://en.wikipedia.org/wiki/Tumut_Hydroelectric_Power_Station#cite_note-GEO3-7">[7]</a> Pump-storage schemes use off-peak energy to pump water to a reservoir on a higher level. This water then passes through turbines to generate electricity when prices are higher.<a href="https://en.wikipedia.org/wiki/Tumut_Hydroelectric_Power_Station#cite_note-8">[8]</a> The sole powerhouse is located above ground, below <a title="Talbingo Dam" href="https://en.wikipedia.org/wiki/Talbingo_Dam">Talbingo Dam</a>.<a href="https://en.wikipedia.org/wiki/Tumut_Hydroelectric_Power_Station#cite_note-GEO3-7">[7]</a></h3>

The power station is fitted with six <a title="Toshiba" href="https://en.wikipedia.org/wiki/Toshiba">Toshiba</a> turbines, each equipped with <a title="Melco" href="https://en.wikipedia.org/wiki/Melco">Melco</a>-manufactured generators,<a href="https://en.wikipedia.org/wiki/Tumut_Hydroelectric_Power_Station#cite_note-GEO3-7">[7]</a> has a combined generating capacity of 1,800 megawatts (2,400,000 hp) of electricity. Three of the six units can operate as pumps. The power station was completed in 1973, upgraded in 2012 and has 150.9 metres (495 ft) rated head. Water is carried in six pipelines, each 488 metres (1,601 ft) long and 5.6 metres (18 ft) in diameter,<a href="https://en.wikipedia.org/wiki/Tumut_Hydroelectric_Power_Station#cite_note-9">[9]</a> delivering water both from and to Talbingo Reservoir.

During 2003, Snowy Hydro commissioned six 140 kilowatts (190 hp) micro-hydro generators on the existing cooling water systems on each of the six generating units at Tumut 3 Power Station. These GreenPower accredited units enable Snowy Hydro to save approximately 3,137 tonnes (3,458 short tons) of <a title="Carbon dioxide" href="https://en.wikipedia.org/wiki/Carbon_dioxide">carbon dioxide</a> per annum. In addition, this installation not only captures previous wasted renewable energy, but also will be substantially reducing the noise that was associated with the previous pressure reducing valves on the six generating unit's cooling systems.<a href="https://en.wikipedia.org/wiki/Tumut_Hydroelectric_Power_Station#cite_note-10">[10]</a><a href="https://en.wikipedia.org/wiki/Tumut_Hydroelectric_Power_Station#cite_note-11">[11]</a> Between 2009 and December 2011, there was a major upgrade of Tumut 3, adding additional capacity in the range of 25 megawatts (34,000 hp) to 50 megawatts (67,000 hp) per unit.

Snowy Hydro Limited is an electricity generation and retailing company in Australia that owns, manages, and maintains the <a title="Snowy Mountains Scheme" href="https://en.wikipedia.org/wiki/Snowy_Mountains_Scheme">Snowy Mountains Hydro-electric Scheme</a> which consists of nine hydro-electric power stations and sixteen large dams connected by 145 kilometres (90 mi) of tunnels and 80 kilometres (50 mi) of aqueducts located mainly in the <a title="Kosciuszko National Park" href="https://en.wikipedia.org/wiki/Kosciuszko_National_Park">Kosciuszko National Park</a>. Snowy Hydro also owns and operates two gas-fired power stations in Victoria and one in New South Wales, three diesel power stations in South Australia, and owns two electricity retailing businesses (<a class="mw-redirect" title="Red Energy" href="https://en.wikipedia.org/wiki/Red_Energy">Red Energy</a> and <a title="Lumo Energy" href="https://en.wikipedia.org/wiki/Lumo_Energy">Lumo Energy</a>).

The company is owned by the Australian Federal government<a href="https://en.wikipedia.org/wiki/Snowy_Hydro#cite_note-4">[4]</a> and whilst not a statutory corporation, is established by the Snowy Mountains Hydro-electric Power Act 1949 (Cth). Prior to its incorporation under the Corporations Act 2001 (Cth), the company was previously known as Snowy Mountains Hydro-electric Authority.
