Snowy 2.0 was declared Critical State Significant Infrastructure (CSSI) in March 2018 because of its potential to contribute to future security of our energy system, the economy and the environment.


The Stage 1 Exploratory Works Application is for approval to investigate the ground conditions at a proposed location for a new 2000 megawatt underground hydro-electric power station in the Snowy Mountains.


The Exploratory Works Application involves:

  • establishment of an exploratory tunnel, construction pad and portal;
  • establishment of a construction compound and supporting infrastructure, including an accommodation camp;
  • excavated rock management;
  • emplacement of excavated rock in Talbingo Reservoir;
  • establishment of barge infrastructure at Talbingo Reservoir; and
  • upgrade and establishment of site access roads.



The Department of Planning and Environment placed the Environmental Impact Statement (EIS) for Snowy 2.0’s exploratory works on public exhibition and encouraged the community to contribute their views.


The broader program of works being considered for Snowy 2.0 involves up to five stages, including the construction of a pumped hydro storage and generation project and major upgrades to the NSW transmission system to connect the proposed power station to major load centres across the state.


Each stage of the project requires a separate applications, which will be publicly exhibited to provide the community an opportunity to comment on each stage.


The Department will continue to engage with local councils, as well as hold community information sessions and provide ongoing information about Snowy 2.0.
