Snowy Hydro is at the heart of Australia’s journey towards a clean energy future. As the nation increases its wind and solar generation, our critical on-demand power and energy storage play a vital role in keeping the grid reliable, enabling Australia to achieve its renewable energy targets and decarbonisation goals.
Our unique portfolio of on-demand power stations is central to this contribution. By flexibly managing our pumped and conventional hydro, gas and diesel power stations, including the iconic Snowy Scheme, we can respond quickly to market conditions to help keep the grid efficient and reliable as more wind and solar come online.
With 660 MW of crucial on-demand capacity, Kurri Kurri Power Station will significantly boost this capability. As our fourth on-demand gas power station, Kurri Kurri Power Station is set to enter full commercial service in 2025, following commissioning, which started in December 2024. The power station first generated electricity for the grid in July 2025.
Beyond the power stations we own and operate, we partner with wind and solar developers to support the growth of clean energy and create economic benefits in regional Australia, while adding other types of renewable energy to our portfolio.
These partnerships currently amount to over 1,700 MW of contracted renewable capacity and allow one of our Retail brands, Snowy Energy, to offer innovative energy products to our customers. We continue to explore the right opportunities to expand our renewable energy partnerships. To further enhance grid flexibility and stability, we are also considering partnerships in short-duration storage like batteries to complement the long-duration storage our pumped hydro assets provide.
Snowy 2.0
Snowy 2.0 is Australia’s largest renewable energy project, and with a 150-year design life will help underpin our clean energy future for generations. A major pumped hydro expansion of the existing Snowy Scheme, Snowy 2.0 will act as a giant battery, storing excess power from increasing amounts of wind and solar energy and delivering it when homes and businesses need it most.
Snowy 2.0’s 2,200 MW capacity is enough to power three million homes for a week, which is the equivalent of around 23 million home batteries. This capacity means it will enable 6,600 MW of wind and solar to come online.
Snowy 2.0’s incredible 350 GWh of energy storage will provide more than half of the 647 GWh of dispatchable energy storage that the Australian Energy Market Operator (AEMO) says the NEM will need to achieve Net Zero by 2050.*
Snowy 2.0 also significantly benefits the Australian economy, with 80% of its investment flowing into national and local economies, while building a skills legacy for future clean energy projects.
