SNOWY 2.0 – PROJECT UPDATE

03/05/2023

Snowy Hydro’s management team is working towards resetting the delivery timeline and budget for the Snowy 2.0 project with its principal contractor, Future Generation Joint Venture (FGJV), as part of an ongoing project review.

The reset will ensure this critically important clean energy infrastructure project is placed on a robust and sustainable footing for FGJV to progress the schedule in a realistic and productive manner.

While significant progress has been achieved by FGJV on Snowy 2.0, there are delays to Snowy 2.0’s contracted schedule and likely cost impacts beyond the contingency allowed, which remain under review by Snowy Hydro.

There are four broad categories of factors contributing to schedule delays and likely cost increases:

the mobilisation and resourcing implications of the COVID-19 pandemic;
the effect of global supply chain disruption and inflation impacting the cost and availability of a skilled workforce, materials, and shipping;
a number of design elements requiring more time to complete due to their technically complex nature, with the final design now being more expensive to construct; and
the impact of variable site and geological conditions, with the most impactful being the soft ground encountered that is delaying tunnel boring machine (TBM) Florence’s progress at Tantangara.

Snowy Hydro anticipates that the timeline for full commercial operation is delayed by a further 12-24 months from the current publicly released dates:

Milestone	Earliest	Latest
First Power	June 2027 – December 2027	June 2028 – December 2028
Commercial operation of all units	December 2028	December 2029

Snowy Hydro expects more detail on the budget implications of the project reset around July 2023, and this will be clearly communicated with key project stakeholders.

Snowy Hydro CEO Dennis Barnes said:

“Since joining Snowy Hydro earlier this year I have focused on ensuring our major projects are placed on a realistic and sustainable footing, while maintaining construction progress.

“This project is critically important to the transition of Australia’s electricity grid and it’s crucial that we are working to a safe, efficient and realistically achievable timeframe to enable orderly planning for all our stakeholders. I am committed to being transparent about our progress and how we are proactively managing the inevitable issues and challenges that arise in a complex project like this.

“While many other major infrastructure projects have been impacted by the same challenges, Snowy 2.0 continues to make positive progress.

“Snowy 2.0 is providing significant employment and economic benefits both regionally and domestically. There are currently over 2,400 people employed on the project and thousands more jobs generated indirectly through supply chains and support services.

“TBM Kirsten has tunnelled 2.9 km to reach the underground power station cavern complex and we now have access to this site from both ends. We shortly expect to commence the 6km tailrace tunnel that will feed into Talbingo Reservoir and the excavation of intakes at Talbingo and Tantangara are proceeding very well.”

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

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.
