SNOWY 2.0 NAMES FOURTH TBM AFTER TUMUT STUDENT

10/09/2025

Monica’s artwork clinches Indigenous naming competition

The fourth mega tunnel boring machine on the Snowy 2.0 project will be named after a talented Tumut High School student who scooped top prize in an Indigenous art and storytelling competition.

Aspiring engineer Monica Brimmer, 15, wowed the judging panel with a stunning piece that reflected the spirit and purpose of Australia’s largest renewable energy project.

Inspired by flowing water, connected dams, mountains, energy, an underground power station and a connection to Country, Monica’s creation was awarded top marks in the competition, organised by Snowy Hydro in partnership with the Stars Foundation and Tumut High School.

Cheered on by her delighted schoolmates during a special school assembly, Monica said her artwork represented the creation of renewable energy and symbolised a “greener future in which the land and our animals are better cared for”.

“When my name was read out I felt nervous and surprised but also really proud. I had hoped to win the competition but I really didn’t expect it,” she said.

“Knowing there’s something really important to the project out there with my name, in the mountains, is really cool.

“I’ve been interested in engineering for quite a while – and it’s pretty cool to put art and engineering together as part of something I could put my mind to.”

Minister for Climate Change and Energy Chris Bowen said Snowy 2.0 is a nation-building project and it’s fitting its next tunnel boring machine will carry the name and vision of a young local student and future engineer.

“Monica’s artwork captures the spirit of clean energy and connection to Country and reflects the brighter, cleaner energy future we’re building together,” he said.

“It’s inspiring to see the next generation in Tumut leading the way on creativity for Australia’s clean energy transformation.”

Snowy Hydro Chief Delivery Officer – Snowy 2.0 Dave Evans said the winning artwork perfectly encapsulated the project’s role in underpinning Australia’s clean energy future.

“Monica’s artwork and the story behind it blew all the judges away,” he said.

“The lightbulb shines bright and displays the power that we’re going to generate for the east coast of Australia through Snowy 2.0’s huge 2200MW capacity.

“It also perfectly highlights our workforce who are almost 1 kilometre deep underground in the Snowy Mountains building one of the world’s biggest power stations.”

Tumut High School principal Brad Taylor said the calibre of entrants was “exceptional”.

“Monica is a highly academic student, and someone that we’re very proud of at the school, so I’m not surprised she’s produced such thoughtful artwork,” he said.

Stars Foundation program coordinator Nioka Marlowe said the competition showcased students’ talents and storytelling skills.

“This made clear to these young Indigenous girls that they’re important – and they’re seen – and gave them an opportunity to be on the big stage,” she said.

The TBM will shortly begin its assembly at the Marica work site, located on the Snowy Mountains Highway near Yarrangobilly Caves, ahead of tunnelling starting in late 2025.

Julie and Monica Brimmer celebrate winning the TBM4 naming competition.

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.

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 for the majority of the time, 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.

If you have any questions or concerns, call the Snowy Hydro Community Hotline at 1800 570 529, get in touch with us via our social media channels or visit the Hunter Power Project webpage.

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 HYDRO RELEASES 2024 SUSTAINABILITY REPORT

13/01/2025

Snowy Hydro has released its 2024 Sustainability Report, covering the progress the energy generator and retailer has made in areas such as environmental stewardship, social impact, and understanding and responding to its carbon emissions and climate risks.

Snowy Hydro CEO Dennis Barnes said the report reflects the company’s role in enabling Australia’s transition to renewable energy, while highlighting its progress and ambitions.

“At Snowy Hydro, we understand that sustainability goes beyond fulfilling our environmental commitments,” Mr Barnes said.

“It’s about supporting our people, driving better diversity outcomes and making a positive difference to the communities we serve.

“The 2024 report shows the progress we are making and achievements we are proud of. While we recognise there is still more to do, this report serves as our roadmap, keeping us accountable and focused on delivering even better outcomes for stakeholders and the community in the future,” Mr Barnes said.

Mr Barnes also acknowledged Snowy Hydro’s responsibility as custodian of the water that flows through the Snowy Scheme, highlighting its role in balancing electricity network reliability, with the irrigation needs of farmers and other water users.

Key sustainability achievements in the 2023/2024 financial year include:

Producing 3,937 GWh of renewable electricity from our hydro generation assets – enough energy to power around 600,000 homes for a year.
Growing our mass market retail brands business to 1.4 million customers, with a focus on delivering authentic, personal customer service.
Our retail brand Red Energy recognised with the Customer Satisfaction Award for the 14th year in a row
7,958 students benefitting from Snowy STEM Academy programs
Keeping our people safe, reflected in our low Total Recordable Incident Frequency Rate (TRIFR) score
Delivering five events of 8-hour peak water flows from Jindabyne reservoir to improve the health of the Snowy River ecosystem
Maintaining outstanding reliability across our generation assets, with our hydro generators starting successfully 99.7 per cent of the time, and gas 98.5 per cent of the time, underpinning our ability to contribute to stable electricity supply
$557,000 spent through our community giving programs
Increasing the proportion of women in senior leadership roles
$320,000 of funding for Murray River rehabilitation work to maintain waterflow and prevent erosion

Snowy Hydro is the third largest generator of electricity in Australia by capacity. We can generate 5,500 megawatts (MW) of electricity across eight hydroelectric power stations, three natural gas power stations, and four diesel power stations.

Snowy 2.0 and the Hunter Power Project are set to deliver 2,860MW of additional capacity. This significant boost to the network’s capacity will make a meaningful difference to energy supply reliability, particularly on hot days in summer.

When these fast-start generating assets come online, they will enable further wind and solar generation that can displace more than 33 million tonnes of CO₂-e per annum.

This carbon emissions displacement would represent a 28 percent reduction in the National Electricity Market emissions from 2022 levels, and approximately 13 percent of Australia’s 2030 total emissions reduction target.

HUNTER POWER PROJECT UPDATE

16/12/2024

Testing and commissioning of Snowy Hydro’s fourth fast-start, on demand gas power station has now begun.

This first phase of commissioning involves pressure testing the Hunter Power Project’s (HPP) approximately 23 kilometre network of pipe infrastructure that will deliver gas, diesel and water to the station’s generators.

Using the latest technology the world’s best manufacturers can offer, HPP will be powered by two of the most gas-efficient turbines available and will be capable of delivering 660 megawatts of electricity to the grid. This significant amount of power will make a meaningful difference to supply reliability, helping the network cope during hot weather and outages of transmission lines and other power stations.

As more wind and solar enters the electricity grid, HPP will play a critical role by providing back-up power to homes and businesses.This means that while HPP is only expected to run around 5 percent of the time, it will enable around 2 gigawatts of renewable energy to be added to the grid, which is the equivalent of displacing around 5 million tonnes of CO2-e every year¹.

PHASED COMMISSIONING

Alongside the pipe pressure tests, HPP’s switching station, which was built by Snowy Hydro as part of the project but handed over to Ausgrid to operate, will be connected to provide the power station with energy from the grid. Testing will then progress to commissioning the first of HPP’s two turbines and generators.

Pending a smooth process, the first turbine and generator is expected to reach full commercial operation by the end of April 2025. Commissioning of the second turbine and generator will follow, with commercial operation of both turbines and generators expected by the end of June 2025.

Depending on commissioning outcomes, there is a possibility of either turbine being available to provide some power to the grid sooner. These target dates are dependent on the commissioning program not being impacted by weather or other factors.

VALUE AND COST

HPP has experienced extended periods of extreme weather and other factors that have stopped work on the project, impacting its timeline. As flagged in the August 2024 project update, HPP’s cost has been impacted in order to minimise the delay in its completion, so HPP can produce power for the network as soon as possible.

Prioritising power availability means the final cost of HPP is expected to be around $1.3 billion, dependent on a smooth transition to commercial operation without delays from weather or other factors.

Despite the change in cost, the strength of HPP’s economic benefit has increased. HPP’s net present value (NPV), has increased to $914 million from $531 million at the March 2021 final investment decision².

This increase in HPP’s economic value has been largely driven by:

more wind and solar generation in the grid increasing the need for HPP to provide on-demand, back-up energy to boost electricity reliability;
a substantial increase in HPP’s gas storage capacity to 70TJ from 43TJ;
HPP’s contribution to managing transmission risk between Sydney and the Snowy Hydroelectric Scheme in the Snowy Mountains, by providing an alternative electricity source for Australia’s largest economy in the event of transmission outages.

LOCAL BENEFITS

The project is delivering substantial jobs and investment benefits to the Hunter region:

To promote interest in STEM career paths and education, HPP’s team has engaged with local students through career expos and presentations, including through partnerships with the Clontarf Foundation in Kurri Kurri, Youth Express and Training Services NSW.

$751 million spent domestically, with $619 million spent in the local Hunter region.

57% of HPP’s workforce are local residents.

20 apprentices are engaged on the project, providing skill development in the Hunter region.

Over $175,000 has been awarded to 39 local projects through the HPP Community Grants Program.

Over $26,000 has been granted to Cessnock LGA schools through the Snowy Hydro Local Schools STEM Fund in 2024.

¹Assumes every 1 MW of dispatchable capacity from HPP enables 3 MW of variable renewable capacity and displaces thermal generation with a carbon intensity of 0.94 t/CO2-e/MWh. Scope 1 emissions from HPP are estimated to be approximately 0.14 million tonnes of CO2-e per annum based on a carbon intensity of 0.52 t/CO2-e/MWh.

²NPVs discounted to March 2021.
