  • Snowy 2.0 Update - Exploratory Works Underway
    6/23/2021 All systems go - latest news from Snowy Hydro Snowy 2.0 update - Exploratory Works underway The Snowy 2.0 Exploratory Works are well underway and there has been plenty of progress on the project. Roads contractor Leed Engineering and Construction has forged ahead with upgrades to Lobs Hole Ravine Road, despite some periods of wild winter weather, and these are due to be completed by the end of the year. A temporary pedestrian bridge is also being installed across Wallace Creek to enable our principal contractor Future Generation access to the exploratory tunnel portal site. When access is completed, the first tunnel construction will get underway with drill and blast methodology. This exploratory tunnel will allow further geological investigations to be carried out at the underground cavern location, with horizontal core hole drilling conducted in-situ. This work is very important as it provides us with information needed to finalise the technical design of the power station cavern, which will be located hundreds of metres below ground. Construction of the first workers’ accommodation camp is due to start in coming months and should be finished early next year. Initially, during the Exploratory Works phase, the accommodation units will be home to around 150 people. Each single bedroom unit will contain an ensuite, bed, desk, television, small refrigerator and reverse-cycle air conditioner. The Exploratory Camp will also have a gym, recreational facilities, dining area and kitchen. Given the project’s location in the Snowy Mountains, all of these buildings are built to withstand up to three metres of snow! Snowy Hydro hosted its latest round of community consultations in July and August, with staff from Future Generation also attending.

  • Snowy 2.0 Transmission Must Be Underground
    Open Letter 18 January 2021 The Hon Rob Stokes MP The Hon Matt Kean MP Minister for Planning and Public Spaces Minister for Energy and Environment Snowy 2.0 transmission must be underground Dear Ministers, You will soon be presented with an Environmental Impact Statement (EIS) proposing high-voltage overhead transmission lines through Kosciuszko National Park for the Snowy 2.0 pumped hydro station. We believe overhead transmission lines would cause extensive, unnecessary, and entirely unacceptable damage to the Park. We urge you to insist on a comprehensive analysis of underground alternatives prior to the submission of the EIS, in accordance with regulatory requirements. The proposed option in the EIS must be for underground cables, not overhead lines. Overhead lines would cause environmental impacts that are totally incompatible with the national and international significance of Kosciuszko National Park. In the absence of your intervention, we understand that four 330 kV overhead transmission lines will be proposed, suspended on two sets of steel lattice towers (up to 75 metres high). The lines would traverse eight kilometres of Park within an easement up to 200 metres wide. One square kilometre of National Park would be permanently cleared. The lines would be visible over a vast area, totally destroying the ambience and integrity of this remote and largely pristine region. This proposal is far more intrusive than any of the single tower lines constructed in Kosciuszko before the Park was established in 1967. Underground cables may be more expensive, but they have several offsetting benefits including minimal environmental impact, higher reliability, reduced maintenance, and less vulnerability to outages from lightning, storms and bushfires.

    Community Fact Sheet Snowy 2.0 Transmission connection project About TransGrid Every day TransGrid connects you to the electricity you use, 24/7. As the operator and manager of the main high voltage transmission network in NSW and the ACT, we connect generators, distributors and major end users to the electricity they need, when they need it. We take a leading role in encouraging the connection of renewable generation and, more broadly, the transition to a low carbon future. TransGrid delivers electricity in a manner that ensures the safety of our workforce and the community. We operate the network at maximum efficiency to deliver electricity at the least-cost to consumers. About Snowy 2.0 The Snowy 2.0 project is being proposed by Snowy Hydro Limited. The project is a pumped-hydro expansion of the Snowy Mountains Scheme which, if approved, will significantly add to it’s existing energy generation and large-scale storage capabilities. Snow 2.0 will increase the Scheme’s generation capacity by up to 2,000 megawatts and provide about 175 hours of energy storage. The ability to pump and store water means Snowy 2.0 will act like a giant battery by absorbing, storing and dispatching energy on-demand, within minutes. The project will be critical to helping provide Australian businesses and households with reliable, stable and affordable energy in the future. www.transgrid.com.au/Snowy2 Community Fact Sheet Snowy 2.0 transmission connection project The Snowy 2.0 transmission connection project Why is it needed? A direct connection to the transmission network is required to get Snowy 2.0’s power into NSW.
