Project overview
Snowy 2.0 involves linking two existing dams, Tantangara and Talbingo, through 27 km of tunnels and building a new underground power station . Water will be pumped to the upper dam when there is surplus renewable energy production and the demand for energy is low and then released back to the lower dam to generate hydro electricity when demand is high. It will provide flexible, on-demand power while cycling the water in a closed loop system. The project also included up to 100 km of new or upgraded roads, extensive spoil management, multiple onsite large scale construction camps, precast creation, storage and transport facilities, many within remote areas of the ecologically sensitive Kosciuszko National Park.
Our involvement
EMM has provided a range of services including strategic advice on the approval pathway, and environmental support through all phases of project development including the feasibility study, concept design, final investment decision, competitive tender for construction, and project execution. EMM assisted Snowy Hydro in having the project declared Critical State Significant Infrastructure (CSSI), and then prepared the environmental impact statement. Subsequently EMM has provided support during the construction process with modifications to the approval and environmental monitoring.
