Snowy 2.0 Pumped Storage Power Station
Snowy 2.0 Pumped Storage Power Station (Snowy Hydro 2.0 or simply Snowy 2.0) is a pumped-hydro battery megaproject in New South Wales, Australia. The dispatchable generation project expands upon the original Snowy Mountains Scheme (ex post facto Snowy 1.0) connecting two existing dams through a 27-kilometre (17 mi) underground tunnel and a new, underground pumped-hydro power station. The project is led by public company Snowy Hydro Limited. Snowy 2.0 is expected to last for at least 100 years, and supply 2.2 gigawatts of capacity and about 350 gigawatt-hours of large-scale storage to the national electricity market. It is the largest renewable energy project under construction in Australia. It includes one of the largest and deepest cavern excavations ever undertaken. It also includes the longest tunnels (at 27 kilometres (17 mi)) of any pumped-hydro station ever built. It is designed for grid stabilization, to be a backup at times of peak demand, and overnight, and during a wet and...
