SNOWY 2.0 STUDY DEEPENS ARCHAEOLOGICAL UNDERSTANDING

25/08/2025

An extensive archaeological technical study carried out across Snowy 2.0 project sites has deepened our understanding of Aboriginal and European occupation in the Snowy Mountains.

Excavation carried out by NSW Archaeology principal archaeologist Julie Dibden found more than 35,000 indigenous stone artefacts across 782sqm at Lobs Hole, Tantangara and Marica work fronts.

The report has found “Aboriginal occupation was not only intense and widespread, but systematic and strategic”.

“The mountains provided people with a resource rich landscape with a mosaic of different environments, each with an abundance and diversity of fauna and plants for food and other material needs,” the report read.

“In addition, the woodlands and forests provided wood for fire … suitable stone for satisfying material and technological need (was) also plentiful.”

The majority of the artefacts found were:

flakes and flake fragments
hammer stones
anvils
mortar stones.

The findings indicate the Lobs Hole valley, with plentiful nearby resources, was used as a repeated base camp for family groups and large gatherings.

Stone shaping – known as knapping – and vegetable handling also occurred.

Hammer stones were found in the valley, demonstrating certain heavy tools were left in place for later use rather than being carried around the steep terrain.

The distribution of artefacts in the Tantangara area shows there were repeated visits by families and small groups over an extended period of time, reflective of its harsher climate.

Community consultation sessions

The report has made a number of recommendations that will be shared at two Aboriginal community consultation sessions in Tumut and Cooma for further discussion.

All Aboriginal community members with a cultural connection to the Snowy 2.0 project sites (Lobs Hole, Tantangara and Marica) are invited to attend.

KURRI KURRI POWER STATION UPDATE

21/08/2025

Testing and commissioning of Kurri Kurri Power Station continues to progress. In recent weeks, we have tested using gas and have successfully started providing electricity to the grid.

To complete commissioning, it is important that we finalise our first generator’s testing on diesel. This will ensure the power station can reliably operate on its diesel back-up fuel at the infrequent times the network is under pressure and diesel generation is required to maintain reliable electricity supply to homes and businesses.

Testing will recommence on Sunday 24 August, and will continue for 12 days over a two to three week period. The testing will take place at different times between 3pm and 10am.

We understand testing in July on the back-up diesel fuel generated visible emissions and an odour that caused discomfort and concern. The level of emissions and odour was not expected and was associated with starting up a brand new generator, combined with strong winds.

Working with the manufacturer, we have identified the best approach to minimise the plume and odour caused when testing on diesel. This involves starting the generator using gas, and then switching to diesel.

Snowy Hydro is also working closely with the NSW Environmental Protection Authority to ensure impacts remain within strict environmental limits.

When fully operational, Kurri Kurri Power Station is designed to run only for a minority of the time, when electricity demand is high and renewable generation is limited. It will operate using gas as its primary fuel, with diesel only being used as a backup.

Kurri Kurri Power Station will play an important role in preventing blackouts and enabling Australia’s decarbonisation. It will provide 660 megawatts of electricity when it’s needed most, allowing more wind and solar generation to enter the grid. It will operate using gas as its primary fuel, with diesel only being used as a backup.

GET SWITCHED ON! SNOWY HYDRO’S POWERING UP THE FUTURE COMPETITION IS BACK FOR 2025

04/08/2025

Do you have a bold and innovative idea that will help build a world run on renewable energy? It doesn’t matter if your idea is big or small, local or global – we want to hear from you!

Snowy Hydro’s national science competition is back for 2025, asking kids and teenagers across the country to consider how they would help to build a future powered by renewable energy – with the most innovative and creative ideas winning prizes for both the inventor and their school.

The Powering Up the Future competition continues Snowy Hydro’s commitment to enhancing access to STEM learning opportunities through the Snowy STEM Academy and its focus on inspiring young Australians to pursue science, technology, engineering and mathematics.

With four major category prizes for both winners and runners up, the Powering Up the Future competition asks students nationwide to be a Snowy Hydro ‘futurist’ and invent a bold new idea, technology or system that helps save or reuse energy to lower emissions as Australia transitions to a renewable energy future.

Snowy Hydro Education Manager Andrew Burke said it was important to engage the workforce of tomorrow in STEM from a young age.

“Today’s children need to be prepared for the future and this competition is a fantastic way to inspire them to think creatively and develop their problem-solving skills, while considering ideas that will transform the energy industry for generations to come.

“Students will walk away from the competition with more knowledge about renewables and energy transmission, and we hope it will spark their curiosity about a future in STEM.”

The Powering Up the Future Competition calls on students who are in years 3 to 12, aged 8+, to think big or small, global or local. If it helps to build a world that runs on renewable energy, the Snowy STEM Academy wants to see it.

Students can take part on their own, or work with their class for a chance to win prizes such as a class set of robots, 3D printers, and STEM kit subscriptions. The competition opens on 4 August, and closes at midnight on 28 September 2025.

The winning entries will be displayed on the Snowy Hydro website and showcased for the public at the Snowy Hydro Discovery Centre in Cooma.

SNOWY 2.0 POWERING OUR FUTURE-READY WORKFORCE

28/07/2025

Beyond building one of the most complex and challenging feats of engineering in the world, through its pumped hydro expansion to the iconic Snowy Scheme, Snowy 2.0 is also leaving a skills legacy.

Eight Year 12 students at Monaro High School have become the first NSW cohort to complete a school-based apprenticeship and traineeship (SBAT) program in supply chain operations, all while working on Australia’s largest renewable energy project.

The Cooma students spent one day a week gaining real-world insights and skills at the Polo Flat segment factory, serving as strong foundation for their careers.

Snowy Hydro CEO Dennis Barnes said the project would create a lasting skills legacy while securing Australia’s clean energy future.

“We are incredibly proud to empower local students by offering career-defining opportunities close to home on this once-in-a-generation project,” he said.

Monaro High School principal James Armitage said students embraced the opportunity to step into the workforce while still attending school.

“This SBAT partnership has shown how powerful it is when education and industry come together with a shared goal of supporting young people into meaningful careers,” he said.

FUNDING BOOST FOR ENDANGERED MACQUARIE PERCH

24/07/2025

Snowy Hydro has partnered with the NSW Department of Primary Industries and Regional Development to expand captive breeding of the endangered Macquarie perch.

Through the Snowy 2.0 Threatened Fish Management Plan, Snowy Hydro has funded the construction of eight new purpose-built aquaculture ponds at Narrandera Fisheries Centre.

This funding will allow for the reintroduction of the species into protected habitats and boost genetic diversity in locations including in the upper Murrumbidgee River below Tantangara reservoir.

Snowy Hydro CEO Dennis Barnes said Snowy Hydro was committed to environmental stewardship while building Australia’s largest renewable energy project.

“We are pleased to work collaboratively with NSW DPIRD Fisheries to carry out the associated monitoring and research that will improve the resilience of Macquarie Perch in both the catchments where Snowy 2.0 will operate and also across the state,” Mr Barnes said.

“Beyond delivering positive environmental outcomes, Snowy 2.0, with a design life of 150 years, will underpin Australia’s clean energy future by storing excess wind and solar power and delivering it to homes and businesses across the grid when it’s needed most.”

KURRI KURRI POWER STATION TESTING UPDATE

18/07/2025

Snowy Hydro’s Kurri Kurri Power Station will recommence testing of the first of its two gas generators on Monday, 21 July 2025. This phase of testing will use gas, which is the generator’s primary fuel and expected to cause substantially less plume and odour than recent diesel testing.

We understand recent testing on the back-up diesel fuel generated visible emissions and an odour that caused discomfort and concern. The level of emissions and odour was not expected and was associated with starting up a brand new generator, combined with strong winds.

After listening to community feedback, we paused this initial phase of testing on the power station’s secondary fuel, diesel. We sincerely apologise for not meeting community expectations regarding providing information about the testing more broadly across the region.

When testing resumes next week on gas, there may be some noise noticed by properties very close to the station, with the potential for a plume and an associated odour during the initial start-up of the turbine. While these impacts will only last a short period and will be dependent on weather conditions at the time of testing, we have also increased the level of air monitoring outside the site boundary.

The nature of turning on a brand new generator for the first time means there is uncertainty regarding how it will perform as we fine-tune the turbines so they operate efficiently when we switch to full operations. Once fully tested, the efficiency of the turbines, which are the latest technology, will result in significantly reduced emissions.

Testing will be undertaken at night and is expected to take 6 to 8 weeks. Improvements to noticeable emissions and odour are expected each week as the commissioning process progresses.

There are appropriately strong rules that apply to the emissions, noise and other impacts from the power station during commissioning and in operation. Snowy Hydro is also working closely with the NSW Environmental Protection Authority to ensure impacts remain within strict environmental limits.

KURRI KURRI FIRES UP FOR THE FIRST TIME

07/07/2025

Commissioning of Snowy Hydro’s fourth on-demand gas power station has achieved a significant milestone, with the Hunter Power Project (HPP) team successfully firing up one of the station’s two class-leading gas turbines late last week.

Snowy Hydro’s Chief Executive Officer Dennis Barnes said ‘first fire’ is an important milestone, which involves the gas turbine igniting and reaching full speed for the first time.

“First fire is a turning point in the power station’s development that confirms the design, construction and cold commissioning of the turbine has been successful,” Mr Barnes said.

“We’re very proud of the project team, whose hard work and dedication have seen us through a very challenging delivery program.”

To be known as Kurri Kurri Power Station in operation, the project’s gas supply infrastructure is now complete. The station is expected to reach full commercial operation in coming months after experiencing several periods of heavy rain over the past year.

The station’s commissioning program has been impacted by 69 days lost to weather impacts in 2025 alone, including during what was the region’s wettest May in 30 years.

Designed to run only for a minority of the time, when electricity demand is high and renewable generation is limited, Kurri Kurri Power Station will have capacity to provide a significant 660 megawatts of power to the grid. This will help reduce pressure on electricity prices, avoid blackouts and cut around five million tonnes of carbon dioxide-equivalent gas emissions annually.

”Every megawatt of capacity provided by Kurri Kurri enables three megawatts of renewable wind and solar to come online and replace increasingly unreliable coal generation,” Mr Barnes said.

“This represents real change in our energy system that will deliver important benefits to energy users across the grid, while making a difference in Australia’s response to climate change.”

Kurri Kurri Power Station remains on track to be delivered within its target cost of around $1.3 billion.

FOURTH TUNNEL BORING MACHINE ON WAY FOR SNOWY 2.0

07/07/2025

Green light for TBM to begin journey to Australia

Snowy Hydro is now preparing for the arrival of its fourth tunnel boring machine to join Snowy 2.0 – Australia’s largest renewable energy project.

This 178-metre long machine has been purpose-built to excavate a 5km tunnel through a complex geological area deep in the NSW Snowy Mountains, known as the long plain fault zone, that will eventually connect Tantangara reservoir with an underground power station built almost 1km underground.

The TBM has now passed factory acceptance testing at Herrenknecht’s Guangzhou factory in China, ensuring all its major systems (mechanical, electrical, control and hydraulics) are validated and the machine is ready to be shipped to Australia.

The pumped hydro expansion to the iconic Snowy Scheme, Snowy 2.0’s incredible scale and power will translate 2200MW of capacity to 350,000 MWh of energy, taking the excess electricity produced by wind and solar during the day and delivering it to provide stability to our energy grid when it’s needed most.

Snowy Hydro Chief Delivery Officer – Snowy 2.0 David Evans said the project would play a pivotal role in enabling Australia’s transition to clean energy.

“Snowy 2.0 is essentially a giant battery, providing long-duration storage for wind and solar power to complement the short-duration storage that batteries provide,” he said.

“The successful completion of factory acceptance testing is testament to months of meticulous design, rigorous testing, engineering excellence and collaboration.”

CLOUD SEEDING UPDATE

30/05/2025

Following a comprehensive review, Snowy Hydro is permanently ceasing its cloud seeding program. This decision follows a review that determined the escalating costs of the program outweighed its benefits.

The review, initially announced in June of last year after a program pause in 2024, concluded that the escalating costs and resources required to continue the program would outweigh any benefits.

Increasing costs were primarily driven by Snowy Hydro’s existing cloud seeding equipment reaching the end of its operational life, meaning significant investment would be needed for it to be replaced.

Rising operational expenses for resourcing and fulfilling regulatory obligations also contributed to the decision.

Snowy Hydro will work with stakeholders to develop a decommissioning plan for equipment removal.

Further Information:

Snowy Hydro has conducted cloud seeding since 2004 to enhance snowfall under suitable conditions. The program was backed by scientific research, independent review, and its operation followed stringent environmental regulation.

SNOWY 2.0 PROJECT UPDATE

28/03/2025

Work on Australia’s largest renewable energy project, Snowy 2.0, continues with good progress across multiple work fronts, despite recent work stoppages.

Across Snowy 2.0, recent progress of note includes:

POWER STATION CAVERNS

Development of the Snowy 2.0 power station complex is progressing well, with excavation and installation of rock support within the caverns more than 35% complete.
The transformer hall is now almost 50% excavated by volume and the machine hall is now 28 metres deep.
The drill and blast tunnels providing access to various levels within the caverns, and other parts of the power station complex are more than 93% complete.
Excavation of the 266 metre-long collector waterway tunnels, which will pass water from the power station to the tailrace tunnel and onto Talbingo reservoir, is 80% complete.

UPPER RESERVOIR INTAKE

A 40-metre high tower crane is assisting with construction logistics in the Tantangara intake pit, where the project’s first permanent concrete structures are being built. More than 6,600 cubic metres of concrete have been poured so far.

LOWER RESERVOIR INTAKE

A total of 370 metres has been excavated from both ends of the connection tunnel which is 825 metres long and will create a connection between the Talbingo intake structure and the tailrace tunnel.
A 70-metre tower crane has been installed to lift heavy equipment and materials in and out of the intake pit.

MARICA SURGE SHAFT

Excavation of the 240 metre deep and 28 metre wide Marica surge shaft has passed 151 metres.
The shaft will provide water storage when Snowy 2.0’s power station starts up. When the station is shutting down, the Marica surge shaft will also provide pressure relief in the headrace tunnel. When completed, it will be one of the widest and deepest operational shafts in the world.

DOWNSTREAM SURGE SHAFT

Excavation of the upper chamber for the downstream surge shaft is 68% complete. This shaft will be approximately 200m high and provide water storage when the power station starts up in pumping mode and pressure relief in the tailrace tunnel when the power station starts in generation mode.

TUNNEL BORING MACHINES (TBMs)
Florence

TBM Florence is excavating the 17-kilometre headrace tunnel, which will connect the underground power station to the upper Tantangara reservoir.
The machine is now more than 3.0-kilometres into the headrace tunnel.

Lady Eileen Hudson

TBM Lady Eileen Hudson is excavating the 6-kilometre tailrace tunnel, which will connect the underground power station to the lower Talbingo reservoir.
The machine has now completed 85% of the tailrace tunnel, having already completed the 2.85-kilometre main access tunnel. This tunnel is now being used by workers to access the power station caverns.

Kirsten

TBM Kirsten is excavating the very steep, 1.6-kilometre Inclined Pressure Shaft (IPS) connecting the underground power station to the headrace tunnel.
The machine has excavated 14% of the shaft to date.
We expect the performance of our tunnel boring machines to continue to vary in line with ground conditions.

TBM4

In December 2024, the NSW Department of Planning, Housing and Infrastructure approved Snowy Hydro’s application to deploy a fourth tunnel boring machine. The machine will help protect the delivery timeline by boosting the project’s ability to tunnel through a complex geological fault zone.
Work to prepare for the launch of the machine is underway. It is set to begin excavation by the end of 2025.

RESTART AFTER WORK STOPPAGES

Underground work on Snowy 2.0 has been progressively restarting over the last two weeks. Operations for all three tunnel boring machines are underway, as well as power station drill and blast cavern excavation.
Above ground work was not impacted and continued throughout the period underground work was stopped.
