MILESTONE FIRST TUNNEL COMPLETED FOR SNOWY 2.0

11/10/2022

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 2,000 megawatt pumped hydro expansion of the mighty Snowy Scheme.

Snowy Hydro acting CEO Roger Whitby said the tunnelling achievement was a significant milestone, with Snowy 2.0 set to underpin the nation’s transition to renewables.

“Snowy 2.0 will not only provide on-demand, quick-start generating capacity for the National Electricity Market (NEM), but a massive 350,000 gigawatt hours of energy storage,” Mr Whitby said.

“This is our first new major tunnel excavation in decades, since construction of the original Scheme, and it gives us access to the site where we will create the enormous cavern 800m underground that will house our power station.

“The TBM Lady Eileen Hudson and our teams from Snowy Hydro and contractor Future Generation Joint Venture have done a great job to complete this critical tunnelling task.

“However, there’s no slowing down. Work across the project continues to move ahead rapidly and this tunnel boring machine is now being dismantled so it can be moved to the Talbingo adit where it will be reassembled with some new components for excavation of the 6km tailrace tunnel.”

While dismantling of the TBM conveyor belt gets underway in the main access tunnel, drill and blast activities are ongoing to excavate cross passages and tunnels to gain access to the power station complex, which will include a 251m-long, 52m-high machine hall cavern and 223m-long, 46m-high transformer hall cavern.

The new work fronts associated with the powerhouse will create further employment opportunities on this clean energy mega-project.

The Snowy 2.0 project will link Tantangara Reservoir (top storage) with Talbingo Reservoir (bottom storage) through 27km of tunnels and a power station with pumping capabilities.

This will enable water to be released for energy generation at times of peak demand and then pumped back to the top storage when there is excess renewable energy in the system, ready to generate again.

Main access tunnel fast facts:

  • 10 metres in diameter
  • Lined with 1,422 concrete rings installed by the TBM
  • Rings comprise 12,798 individual segments manufactured locally in Cooma
  • Has four cross-passages linking it to the adjacent emergency, cable and ventilation tunnel
  • Also has four cross tunnels and a turning bay to facilitate construction access around the power station complex
  • Provides pedestrian and vehicle access into the power station

TBM FLORENCE ON THE MOVE

05/10/2022

Tunnel boring machine (TBM) Florence continues excavating the Snowy 2.0 headrace tunnel at Tantangara following successful reinforcement works.

As anticipated, the ground conditions encountered by the TBMs on Snowy 2.0 have been highly variable, ranging from soft, sandy ground to extremely hard rock. 

The Snowy 2.0 teams have been working collaboratively to safely navigate the softer ground conditions experienced at Tantangara, including high groundwater inflows.

As part of the tunnelling process we probed in advance of the TBM, identifying the soft ground ahead, and then consulted with our expert design consultants to plan for stabilisation works. TBM Florence has been specifically designed to encounter these variable ground conditions.

Consolidation grouting around the perimeter of the headrace tunnel, and internally, the installation of steel ribs to reinforce the concrete segmental lining in the soft zone, have been carried out to ensure stability and manage groundwater inflows. Additional instrumentation to monitor ground performance has also been installed.  

Successful execution of the reinforcement works by Snowy 2.0 principal contractor Future Generation Joint Venture (FGJV) is enabling the TBM to carefully thrust off the segments and move forward.

Snowy Hydro expects variable and soft ground conditions to occur in sections of the very long 17-kilometre headrace tunnel. Further ground improvement works – a typical tunnelling process – will be carried out where required so the TBM can safely advance.

Snowy Hydro and its Future Generation Joint Venture partners are working towards the successful delivery of Snowy 2.0.

MILESTONE FOR LOCAL SNOWY 2.0 CONCRETE SEGMENT FACTORY

09/08/2022

Snowy Hydro’s Snowy 2.0 precast factory in Cooma has achieved an impressive milestone, with manufacturing completed for all concrete segments that will line the dry access tunnels.

More than 25,000 of these seven-tonne segments have been produced at the Polo Flat factory, which employs 120 people from the 2,100-strong Snowy 2.0 workforce. The segments are being used to line the main access tunnel and emergency, cable and ventilation tunnel at Lobs Hole.

In total, 36,000 or 27% of the 130,000-plus segments needed to line all of the Snowy 2.0 tunnels have now come off the Polo Flat production line, said Paul Broad, Snowy Hydro’s Managing Director and CEO.

“We’re proud to be manufacturing and investing locally, and providing employment opportunities for local people as well,” Mr Broad said. “The precast factory is operated by our principal contractor Future Generation Joint Venture and it is powering along.

“To efficiently and safely produce enough of these massive concrete segments to line the 5.6 kilometres of dry access tunnels is a terrific achievement.”

The factory supports the operation of the three Snowy 2.0 tunnel boring machines, which are excavating 27 kilometres of tunnels from Tantangara Reservoir to Talbingo Reservoir for the Snowy 2.0 pumped-hydro expansion of the Snowy Scheme.

The Polo Flat facility includes a concrete batching plant and segment manufacturing from two automated carousels, producing up to 24 rings, each one made of nine segments, per day.

Many of the raw materials like aggregates and sand are sourced from the local Schmidt Quarries at Mt Mary and Nimmitabel, which is reducing transport time and costs. Concrete is mixed within the batching plant, which is then transferred into the factory and poured into specially-designed moulds. 

With the use of innovative robotics, the moulds progress along the carousel as the segments cure and finish. There is an onsite laboratory and testing to check the quality of every segment produced.

Snowy 2.0 is leading the way in Australia to successfully deploy and use robots to automate the process of demoulding, cleaning and application of the release agent on the moulds, before pushing them through to the next production stage. This has allowed the factory to maintain a safe and low-noise working environment for workers. 

It takes approximately eight to 10 hours to cure and de-mould each segment from start to finish, then they are stored for about two weeks before being transported to site, loaded into TBMs and installed in the tunnels.

FAST FACTS – DRY TUNNEL SEGMENTS

  • Number produced = 25,210
  • Distance if all these segments were placed side-by-side = 86.3 kilometres
  • Tonnes of concrete used = 151,260
  • Equivalent rings (nine segments per ring) = 2,802
  • These segments – designed to provide durability under extreme fire loads – have been laboratory tested for fire loads of 1,350 degrees Celsius for up to 120 minutes.

Snowy 2.0 project background: Snowy 2.0 is a nation-building project that will underpin thousands of megawatts of renewables and will continue to keep the lights on for generations to come.

Snowy 2.0 will link two existing Snowy Scheme reservoirs, Tantangara and Talbingo, and its new  power station with six pump-turbines will be located about 800m underground. Water in the top storage will be released for energy generation at times of peak demand and pumped back at times when there is excess renewable energy in the grid, so Snowy 2.0 is ready to meet demand when needed.

SNOWY 2.0 POWERING AHEAD WITH COMMISSIONING OF TUNNEL BORING MACHINE FLORENCE

22/03/2022

Snowy Hydro and members of the local community have today come together to celebrate the commissioning of the third and final tunnel boring machine (TBM) for Snowy 2.0, Australia’s largest renewable energy project.

The 143 metre-long TBM Florence is one of a trio of technologically-advanced machines excavating more than 27 kilometres of waterway tunnels as part of Snowy 2.0, the huge pumped-hydro expansion of the iconic Snowy Mountains Scheme that is ensuring Australia’s secure and reliable transition to renewables.

Snowy Hydro Managing Director and CEO Paul Broad joined Snowy Mountains community members and representatives from Snowy 2.0 principal contractor Future Generation Joint Venture for a celebration event and ribbon-cutting at Tantangara, where TBM Florence is being launched to excavate the headrace tunnel.

Mr Broad said it was a wonderful experience sharing a significant project milestone with the community, former Snowy Scheme workers and local school children and businesses.

“We want to thank the local community for their support. It’s great knowing that this massive project is delivering thousands of jobs, many training and apprenticeship opportunities for workers, and a major economic boost for the Snowy Mountains region and beyond,” Mr Broad said.

“The progress we’re making on Snowy 2.0 is terrific. The other two TBMs, Lady Eileen Hudson and Kirsten, are already powering ahead excavating the main access tunnel and emergency, cable and ventilation tunnel at Lobs Hole, so we’re delighted to be starting this very long and deep headrace tunnel from Tantangara.

“Watching TBM Florence’s big blue cutterhead spin today alongside people who helped build the original Scheme highlights the pride we at Snowy Hydro have in our pioneering past and how exciting the renewable energy future is with Snowy 2.0.”

There are almost 1,800 people currently working on Snowy 2.0, including hundreds of locals, with the project generating about 4,000 direct jobs and many more in the supply chain.

Snowy 2.0 will deliver 2,000 megawatts of pumping and generating capacity and 175 hours of storage – enough to power 500,000 homes simultaneously – which will underpin thousands of megawatts of intermittent renewables. 

Named after Australia’s first female electrical engineer, Florence Violet McKenzie (1890-1982), TBM Florence is set to excavate 14.9 kilometres of the 17km headrace tunnel. The 11-metre diameter Herrenknecht-designed machine has been purposely designed to manage hazardous dust and poor ground conditions while tunnelling up to 450 metres underground.

TBM Florence was named by local Berridale student Riley Douch as part of the Snowy 2.0 Tunnel Boring Machine Naming Competition, which highlighted ground-breaking Australian women in science, technology, engineering and maths (STEM).

ONE KILOMETRE SNOWY 2.0 TUNNELLING MILESTONE

09/12/2021

Snowy 2.0, a nation-building pumped-hydro project that will provide Australia with on-demand, clean, renewable energy and large-scale storage, is celebrating its inaugural tunnelling milestone.

The project’s first tunnel boring machine (TBM), the Lady Eileen Hudson, has passed the one kilometre mark of the 2.6km main access tunnel, which leads to the site of the underground power station cavern.

Minister for Industry, Energy and Emissions Reduction Angus Taylor said Snowy 2.0 is going from strength to strength.

“Reaching this critical milestone brings Snowy 2.0 closer to delivering 2,000 megawatts of fast-start, dispatchable energy needed to make our grid secure and keep pressure on power prices for Australian families and businesses,” Minister Taylor said.

“Snowy 2.0 will store the excess energy from Australia’s world-leading levels of household solar and use that energy when the sun goes down, enough to power the equivalent of 500,000 homes for over a week during peak demand.

“The project is providing a major job and economic boom for the Snowy region, building on the great legacy of the Snowy Scheme, a national icon.”

Snowy Hydro Managing Director and CEO Paul Broad said the tunnelling achievement highlighted the Snowy 2.0 project’s outstanding construction progress.

“It’s an exciting time in the mountains with Snowy 2.0 – this is a megaproject that’s on-budget and due to produce first power in 2025 as planned,” Mr Broad said.

“Tunnelling at Lobs Hole is going very well, with about 4,500 concrete segments manufactured locally at our factory in Cooma used to create 500 rings to line the first kilometre of the main access tunnel. In total, around 130,500 segments will be produced for the Snowy 2.0 tunnels.

“We are also getting ready to launch our second TBM, named Kirsten, with our principal contractor, Future Generation Joint Venture.

“The progress being made by the project’s growing 1,400-strong workforce is particularly noteworthy given the very difficult scenarios we’ve faced as a result of the COVID-19 pandemic restrictions and bushfire impacts over the last year and a half.

“It’s particularly good to see the training and upskilling opportunities Snowy 2.0 is providing, creating lots of apprenticeships and giving local people the chance to work on the TBMs.”

There are three Snowy 2.0 TBMs, which will collectively tunnel more than 27km between Tantangara and Talbingo reservoirs. A power station with pumping capabilities will be located more than 800m below ground.

Snowy 2.o’s 2,000 megawatts of pumping and generating capacity and 350,000 megawatt hours of storage will underpin thousands of megawatts of intermittent renewables.

SNOWY 2.0 RAMPS UP WITH COMMISSIONING OF SECOND TUNNEL BORING MACHINE

06/12/2021

Snowy Hydro has today achieved another exciting milestone, with the commissioning of the second tunnel boring machine (TBM) for Snowy 2.0, Australia’s largest renewable energy project.

The 11-metre diameter TBM Kirsten, one of the most innovative and technologically-advanced machines in the world, is one of three TBMs that will excavate more than 27km of tunnels for the massive pumped-hydro expansion of the iconic Snowy Scheme.

Snowy 2.0, which is on-budget and due to produce first power in 2025, is fundamental to Australia’s transition to a renewable energy future. Its 2,000 megawatts of pumping and generating capacity and 175 hours of storage – enough to power 500,000 homes simultaneously – will underpin thousands of megawatts of intermittent renewables.

Snowy Hydro CEO Paul Broad said Snowy 2.0 was creating 4,000 jobs and significant training and apprenticeship opportunities for workers, while providing a major economic boost for the Snowy Mountains region and beyond.

“Our first TBM, the Lady Eileen Hudson, is already a kilometre into the mountain excavating the main access tunnel and now we have TBM Kirsten continuing the tunnelling and construction progress for this amazing project,” Mr Broad said. 

“Our growing workforce of almost 1,400 includes hundreds of people from the local region and we have invested more than $70 million with local businesses so far.

“Upskilling workers and investing in the future of our youth will be important legacies of this project so it is very pleasing to see Snowy 2.0 apprentices around site learning their trades and local people having the chance to work on the TBMs.”

Mr Broad, Prime Minister Scott Morrison, Industry, Energy and Emissions Reduction Minister Angus Taylor, and representatives from Snowy 2.0 principal contractor Future Generation Joint Venture, today toured TBM Kirsten at Lobs Hole and watched the cutterhead spin.

Named after NSW astrophysicist and popular science communicator Kirsten Banks, TBM Kirsten is set to excavate the 2.9km emergency, cable and ventilation tunnel (ECVT), which provides alternate access to the underground power station. The 205-metre-long TBM will then bore the 1.4km inclined pressure shaft (IPS) and a 2.4km section of the headrace tunnel.

TBM Kirsten is setting a global standard in tunnel boring technology, just as the original Snowy Scheme developed rock bolting techniques that are still used throughout the world today. 

It has been specially designed to excavate the IPS on a very steep gradient (to +47% or a 25-degree angle) so all equipment within the TBM can switch to work on the incline, and the stairways and walkways pivot to remain horizontal.

TBM Kirsten was named earlier this year by local student Kobe Burnes as part of the Snowy 2.0 Tunnel Boring Machine Naming Competition, which highlighted leading Australian women in STEM.

FREE TRAINING TO HELP LOCALS LAND SNOWY 2.0 JOBS

12/11/2021

A graduation ceremony has been held today in Wagga Wagga for Aboriginal people who have completed a fee-free skills training program as part of the multi-billion dollar Snowy 2.0 project.

Nine participants in the program celebrated their graduation at an event attended by the Federal Member for Riverina, Michael McCormack MP and Wagga Mayor, Greg Conkey. Another program participant is already employed at the Snowy 2.0 concrete segment factory in Cooma.

The seven-week pre-employment training was an initiative of Snowy Hydro’s Snowy 2.0 principal contractor, Future Generation Joint Venture, and funded by Training Services NSW. 

Snowy 2.0 is the largest renewable energy project in Australia and will utilise pumped hydro to significantly expand the Snowy Scheme. It will deliver on-demand power to 500,000 homes at the same time, and large-scale storage to underpin thousands of megawatts of intermittent renewables. Two existing dams are being connected as part of the project through 27-kilometres of tunnels and a new underground power station. 

The Minister for Skills and Tertiary Education Geoff Lee said this was a great example of upskilling people in the regions to benefit from major infrastructure projects.

“This $5.1 billion Snowy Hydro project is expected to create 4,000 jobs over the life of the project, and it’s important that local people get the opportunity to work on it,” Mr Lee said.

The program saw participants learn to carry out and measure calculations, use construction tools and equipment and meet WHS requirements. 

Future Generation, in partnership with TAFE NSW, developed the program after consultation with the Aboriginal community, and included yarning circles and Indigenous artworks. 

Snowy Hydro Relations Manager Dean Lynch said the training and upskilling opportunities associated with Snowy 2.0 would create an important legacy.

“At Snowy Hydro we have a long-established culture of providing learning opportunities for employees and we are delighted that through Snowy 2.0 we can generate education and ongoing benefits for local and regional communities. This training is helping people acquire skills that make them job-ready and will be great not only for Snowy 2.0, but other construction projects in the future.”

The program is thanks to collaboration between Training Services and TAFE NSW, NIAA, NSW

Aboriginal Affairs, Corporate Connexions, Department of Education Skills & Employment, Job Active providers and all the present and emerging elders who have been directly involved.
