Webuild and its partners in the Future Generation joint-venture celebrated with Snowy Hydro Ltd the commissioning of the first of three technologically advanced tunnel-boring machines assigned to Snowy 2.0, a major milestone. As the largest renewable energy project in Australia, Snowy 2.0 will expand Snowy Hydro’s network of hydro power stations to support the country’s transition to a low-carbon emissions future.
Designed specifically for Snowy 2.0, the TBMs highlight the innovation that Webuild brings to every project. In particular, another of the TBMs will be one of the first in the world to be able to excavate on a range of variable slopes as well as on very steep angles: at a descendent of up to 9% (five degrees) to an ascent of up to 47% (25 degrees).
Assembled onsite after its components were transported from Port Kembla, the ‘Lady Eileen Hudson’ TBM with a 11-metre diametre will excavate the 2.6-kilometre main access tunnel to where a cavern will be dug to house the underground powerhouse of the pumped-storage scheme. The TBM will then be dismantled and reassembled at the Talbingo portal where it will excavate the tailrace tunnel.
Set in the Snowy Mountains, Snowy 2.0 will provide 2,000 megawatts of fast-start, dispatchable energy and provide 350,000 megawatt hours of large-scale storage, enough to power the equivalent of 500,000 homes for over a week during peak demand. It will reduce volatility in the power market, support reliability and bring down power prices for families and businesses.
