The NSW government has now released the Environmental Impact Statement (EIS) for the Snowy 2.0 hydro project.
At the core of the Snowy Hydro 2.0 expansion will be the establishment of a new underground tunnel linking the Tantangara and Talbingo reservoirs and the commissioning of a new underground power station that will operate as Australia’s largest pumped hydro energy storage system.
The main works for the Snowy 2.0 project will include the removal of an estimated 9 million cubic meters of excavated rock. The federal government owned Snowy Hydro has proposed that more than half of this excavated material be relocated within either the Talbingo or Tantangara reservoirs, with the remaining material used to establish permanent structures, or for land forming.
While the prospect of a renewed Snowy Hydro scheme, operating as the ‘battery’ for the eastern seaboard, has appeal from a climate angle, it has not – until now – been clear what the physical footprint of the project might be. The EIS outlines the likely direct impacts of the works that would be required under the scheme. The National Parks Association of NSW (NPA) says that the EIS ‘proposes a completely unacceptable level of damage to Kosciusko National Park’.
