Good progress continues to be made at Tantangara (eastern end of the Snowy 2.0 project), with the headrace tunnel adit and tunnel boring machine cradle almost complete.
Other works underway include the cofferdam, concrete batch plant and water treatment plant, and worker camp.
On 22 March, the local community came together to celebrate the commissioning of tunnel boring machine (TBM) Florence. Named after Australia’s first female electrical engineer, Florence Violet McKenzie (1890-1982), TBM Florence is set to excavate about 15 kilometres of the 17km headrace tunnel. TBM Florence was named by local Berridale student Riley Douch who along with his family visited Tantangara today for the TBM commissioning community event.
Snowy Hydro is celebrating the completion of excavation for its first tunnel for Snowy 2.0, with the Lady Eileen Hudson tunnel boring machine (TBM) reaching the location of the new underground power station cavern. The 11-metre diameter TBM has excavated 2.85km to create the main access tunnel at Lobs Hole in the Snowy Mountains, where a workforce of more than 2,200 people are building Snowy 2.0 – the 2,200 megawatt pumped hydro expansion of the mighty Snowy Scheme.
The Snowy 2.0 pumped-hydro mega project has achieved another important construction milestone, with a second tunnel excavation completed at Lobs Hole in the Snowy Mountains. The 2.93-kilometre emergency, cable and ventilation tunnel (ECVT) has been excavated and fully lined with 13,140 locally-manufactured concrete segments by tunnel boring machine (TBM) Kirsten. This achievement follows the excavation of the adjacent main access tunnel (MAT), which was completed in October 2022.
