Following the Snowy 2.0 project reset announcement, Snowy Hydro and Future Generation contractors are working together to achieve full commercial operation by December 2028.

The Snowy 2.0 Project Team is focused on excellent environmental outcomes while maintaining all-important safety principles. Safety is the number one priority for Snowy Hydro and core to the company’s values. High expectations for the management of all safety risks extend across the Snowy 2.0 project, without compromise.

Snowy 2.0 is critical to Australia’s transition to a low-carbon economy and when complete it will have broad-scale environmental benefits. Consistent with its responsible operation of the Snowy Scheme in Kosciuszko National Park for almost 70 years, Snowy Hydro is equally committed to minimising potential impacts from Snowy 2.0.

SAFETY PERFORMANCE
– As at September 2023, the project’s 12-month rolling TRIFR (Total Reportable Injury Frequency Rate) is 2.97, below the target of 4.0.**
– There has been a reduction in recordable and serious incidents on the project, with a focus on planning and a coordinated approach to safety management.
– Snowy 2.0 works closely with Comcare and SafeWork NSW and will continue to incorporate lessons learned and findings from the regulator into operational practices. 
**Calculated per million hours worked. Total hours worked to end September 2023: >17.7 million.

Construction of Snowy 2.0 will temporarily impact less than 0.1% of the park with any short-term unavoidable impacts rehabilitated throughout the project, in accordance with environmental project approvals. This includes around $100 million provided by Snowy Hydro to the offsets program for Kosciuszko National Park. Once operational, Snowy 2.0’s footprint within the park will be only 0.01%.

ENVIRONMENTAL PERFORMANCE
– 4 independent audits of the Snowy 2.0 project undertaken since project commencement. 
– 1,500 hours spent annually to proactively monitor the 163 biodiversity sites.
– More than 200 kilograms of native seed collected over three years for rehabilitation activities.
– 27 heritage site excavations and more than 35,00 indigenous artefacts salvaged and currently being documented, adding to the history of the Snowy Mountains Indigenous people. 

In this month’s update from the main worksite at Lobs Hole, Project Integration Manager Paul Smith recaps progress to date with over 40 per cent of Snowy 2.0 now complete, including:

  • Excavation of the 2.85 kilometre main access tunnel, lined with almost 13,000 locally manufactured concrete segments.
  • Excavation of the 2.9 kilometre emergency, cable and ventilation tunnel. 
  • Major upgrade of Ravine Road, the steep and winding 15 kilometre access road into Lobs Hole.
  • Infrastructure to support construction including the main yard workshops, worker campsites and more than 50 kilometres of access roads across three main worksites at Lobs Hole, Marica and Tantangara.

Excavation is underway of the huge 250 metre-long underground power station cavern and the tailrace tunnel, and TBM Kirsten is being modified to excavate the world-leading inclined pressure shaft. Drill and blast to create 11 cross passages and construction tunnels continues.

Above ground, there is plenty of activity across all sites. Lobs Hole Surface Works Project Manager Steve Lee helps ensure the Snowy 2.0 project is delivered in a safe and timely way, and to the quality standards and requirements of Snowy Hydro.

Surface works refers to a broad mix of activity such as haulage of spoil, maintenance of site roads, environmental controls, main yard area activity, office facilities and directional drilling, as well as the Talbingo intake build.

Latest progress on site includes Stage 2 earthworks with a recent blast covering an area of 4,500 square metres. About 10,000 cubic metres of material is being removed as the excavation of the 104-metre-high intake continues.

Snowy 2.0 is the largest renewable energy project under construction in Australia and will provide crucial deep storage central to Australia’s renewable transition. When complete, Snowy 2.0 will deliver 2,200 megawatts of dispatchable generation.

Snowy 2.0 is being delivered by Future Generation joint venture between:
