Snowy 2.0 is a major pumped-hydro project which will supercharge the Snowy Scheme’s existing hydro-electric generation and large-scale storage capabilities. The fast-start, on-demand generation of pumped-hydro and Snowy 2.0’s massive storage capacity will be vital as more intermittent, renewable energy sources such as wind and solar come online and coal-fired power stations retire.
Snowy 2.0 will add 2,000 megawatts of energy generation and provide 175 hours of storage for the National Electricity Market (NEM), enough to ensure the stability and reliability of the system during prolonged weather events, such as wind or solar ‘droughts’. 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 existing capability and ensure that we can continue to provide increased stability and security to the energy market well into the future.
