The 2GW Snowy 2.0 pumped storage project has hit a major milestone with the news that New South Wales Government has approved the main works for Australia’s biggest energy storage project.
Deputy Premier and Member for Monaro John Barilaro said planning approval for the Snowy 2.0 Main Works would mean new jobs, big investment and big infrastructure for regional NSW.
“Snowy Hydro is an icon of our community, with Snowy 2.0 already employing about 500 people, directly injecting more than $35 million into the Snowy Mountains and involving more than 100 local businesses,” Barilaro said. “This latest approval will see the creation of an extra 2000 jobs during the construction phase, unlock billions of investment in regional NSW and allow the next stage of construction to further progress this legacy project.”
The project involves the construction of a power station that sits about 800m underground and is about 240m long. It also includes the construction of 27km of tunnels between the Talbingo and Tantangara Reservoirs, lined with 130,500 concrete segments manufactured locally in Polo Flat.
Once complete, the project will add 350GWh of energy storage and 2000MW of generation capacity to the state’s grid – enough to power 500,000 homes during peak demand – and play a major role in the National Electricity Market (NEM) by facilitating the development of renewable energy and putting downward pressure on electricity prices.
Planning and Public Spaces Minister Rob Stokes said the project’s approval includes strict conditions to minimise and offset environmental impacts.
“In March 2020 we approved the Snowy 2.0 Segment Factory, and this month we have approved the Snowy 2.0 Main Works, enabling the creation of new jobs and the flow of substantial investment into our state,” Stokes said. “The projects approval also requires Snowy Hydro to invest almost $100 million for biodiversity and environmental offsets to protect threatened species and deliver long-term conservation and recreational benefits for the Kosciuszko National Park.”
Snowy Hydro’s CEO, Paul Broad, said that today’s announcement is another major milestone for Snowy 2.0 which is progressing full steam ahead, creating more jobs and significant investment in regional communities.
“Snowy Hydro has been operating responsibly in Kosciuszko National Park for almost 70 years,” Broad said. “For a small and temporary construction footprint covering just 0.10% of the park, we will deliver 2000MW of large-scale energy storage to support many other wind and solar projects coming online.”
As part of the approval, the proponent will be required to invest $5 million to develop a captive breeding program for the threatened Stocky Galaxias and Macquarie Perch, install fish-screens to minimise the risk of transfer of pest species downstream, develop an app to share information gathered for the project with visitors of the national park, and restore native vegetation and threatened species habitat once construction infrastructure is decommissioned.
While Exploratory Works continue to progress on site, the project will now be referred to the Australian Government for final approval before Main Works construction commences in the coming months.
In April last year it was announced that a Joint Venture of Italy’s Salini Impregilo and Australia’s Clough won a contract for the civil works and electromechanical component of the Snowy 2.0 project. Voith Hydro is to supply six reversible pump turbines, each with a rated output of 333MW, three of which are variable-speed, to the project.
