Snowy Hydro says work on a major part of its multibillion-dollar pumped hydro project remains halted after the collapse of a tunnel, adding to concerns the venture will face further lengthy delays.
The commonwealth-owned power giant last month announced a “surface depression” had formed above the main tunnel at the Tantangara site of its Snowy 2.0 project. At the time, it said tunnelling was continuing and that the integrity of the tunnel “has not been compromised”.
