Snowy 2.0

Snowy 2.0  is an expansion of the existing Snowy Hydro Scheme. The Project will add 2.2 gigawatts (GW) of dispatchable capacity to Snowy Hydro’s portfolio (originally proposed at two GW).

The pumped hydro-electric scheme elements of Snowy 2.0 Main Works are mostly underground between the southern ends of Talbingo and Tantangara reservoirs, a straight-line distance of 27 kilometres, otherwise known as the Yarrangobilly Pumped Storage Scheme.

The project originally had an expected six-year construction period. The current expected construction period is eight years.
