Snowy 2.0

On 16 March 2017, Snowy Hydro announced its proposal to carry out a feasibility study into the expansion of the pumped hydro-electric storage in the Snowy Mountains Scheme, also known as the Snowy 2.0 project.

Snowy 2.0 is a pumped hydro project that will increase generation capacity of up to 2000 megawatts, and at full capacity, about 350 000 megawatt hours of energy storage. As the economy decarbonises, more intermittent generation (such as wind and solar) will enter the market as baseload coal generation continues to retire.

This creates the need for new sources of dispatchable energy generation like pumped hydro as well as the need for large-scale storage. Snowy Hydro already plays a critical role in ensuring system stability and at times of peak demand we keep the lights on. Snowy 2.0 will enhance our capability further and ensure that in the future we can play a bigger role in providing stability and security to the energy market.

The feasibility study for Snowy 2.0 is well underway and will be complete in December 2017. Once completed, Snowy Hydro’s independent Board of Directors will assess the outcomes (both technical and economic) of the study and make a decision on next steps.
