Spotlight on Tantangara - Tantangara Reservoir was originally completed in 1960 as part of the original Snowy Scheme, and today it’s one of the most crucial components for the iconic Snowy 2.0 project. 

Excavation of the Tantangara Intake is well under way, with close to 100,000 cubic metres of earth moved to-date – that’s more than enough to fill the Sydney Opera House!

Check out our recent drone flyover of the Tantangara site on our YouTube Channel here.

Tantangara will serve as the entry point for water travelling through the 16-kilometre headrace tunnel – the longest tunnel in the project - connecting it to the underground power station via the inclined pressure shaft.

Once water has passed through the turbines to generate electricity, it flows to Talbingo Reservoir via the tailrace tunnel. The turbines can then reverse to pump the water back up to Tantangara, where it is stored and ready to generate power again when needed.

About the Project
 
Webuild and Clough, as part of the Future Generation Joint Venture, are delivering the civil and electro-mechanical works for the Snowy 2.0 Project which will link two existing Snowy Scheme dams, Tantangara and Talbingo, through underground tunnels to the depths of up to one kilometre and an underground power station with pumping capabilities.
 
Snowy 2.0 will provide an additional 2,200 megawatts of dispatchable, on-demand generating capacity and approximately 350,000 megawatt hours of large-scale storage to the National Electricity Market, 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 at times of peak demand, and Snowy 2.0 will enhance this existing capability and ensure that it continues to provide a secure and reliable transition to renewables.
