NSW Department of Planning and Environment

The Snowy 2.0 Exploratory Works Application was approved in February 2019.


The Exploratory Works investigate the ground conditions at the proposed location for the 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.
  • upgrade and establishment of site access roads.



The department assessed the application for Snowy 2.0’s Exploratory Works, taking into account environmental, social and economic impacts, community and stakeholder submissions and advice from other government agencies.


The Minister for Planning determined the proposal in February 2019.


Construction commenced in early 2019.


All documents relating to the application are available on our Major Projects website.
