UPDATED: JINDABYNE LAKE LEVELS

11/01/2022

December 2021 was officially the wettest since records began for the Lake Jindabyne catchment. The lake level will continue to stay high throughout summer. 

Daily water releases from the lake of up to 3,000 megalitres (ML) per day will continue until at least 17 January. It is likely that additional flows above the notified environmental releases will continue down the Snowy River while wet conditions persist. Snowy Hydro will continue to look for opportunities to pump water to Geehi Reservoir, however, at times, the surplus of water pumped to Geehi will be returned to Jindabyne.

It remains possible that the storage may again reach 100% (or full supply level), triggering operation of the spillway gates. Dam safety is paramount at this time and the spillway gates will automatically release water at any time the storage reaches or exceeds 100%.

NSW Department of Planning, Industry and Environment (DPIE Water) have been consulted on this plan and continue to work closely with Snowy Hydro to make controlled releases to manage the spill risks and minimise downstream impacts.

For the community, the most important message is to stay safe and well-informed. The public can stay updated about flood alerts here:

JINDABYNE DAM SPILL

20/12/2021

Following recent significant rainfall events, Jindabyne Dam reached full supply level (FSL) today and commenced spilling into the Snowy River this morning.

Up to 140mm of rain was recorded in Snowy Scheme catchments over the weekend, continuing what has been a very wet year and the wettest November/December since 1992.

The spillway is likely to continue to operate intermittently for the next few days and Lake Jindabyne will remain very close to FSL this week.

With further storm activity forecast for the Christmas weekend and limited opportunities to pump water from Lake Jindabyne into the Murray River catchment, it is expected the spillway may operate again by the end of the week.

Snowy Hydro is working closely with NSW Department of Planning, Industry and Environment (Water) to identify opportunities to make controlled releases and manage downstream impacts. Dam safety is paramount at this time and the spillway gates will automatically release water to return the storage to 100%.

Lake levels are anticipated to remain high for at least the next month, with continuing wet weather predicted in the seasonal outlook.

For the community the most important message is to stay safe and well-informed.  The public can stay updated about flood alerts here:

Keeping the lights on for generations to come

26/02/2019

At Snowy, we have a proud history and a strong vision. Snowy Hydro, supercharged by Snowy 2.0, will underpin Australia’s renewable energy future and keep the lights on for generations to come.

Almost 70 years after the first sod was turned on the mighty Snowy Scheme, we will do it all again. Today, after consideration of our Board’s Final Investment Decision, we welcome Shareholder approval of Snowy 2.0.

“It’s an exciting time for our Company,” Snowy Hydro CEO Paul Broad said. “Snowy 2.0, like the original Snowy Scheme, is a nation building project that is vital to Australia’s economy and our energy transition.

“This significant expansion of the Snowy Scheme will provide the storage and on-demand generation needed to balance the growth of wind and solar power and the retirement of Australia’s ageing fleet of thermal power stations. In short, it will keep our energy system secure.

“Snowy 2.0 is not only a sound business investment for Snowy Hydro with over 8% return on investment. It also represents the most cost-effective way to ensure a reliable, clean power system for the future.

“When it is completed, Snowy 2.0 will be able to deliver 2000MW of on-demand generation, up to 175 hours of storage, and deliver more competition that will keep downward pressure on prices.

“We are committed to continuing to grow our portfolio of assets, to maximise competition in the National Electricity Market (NEM) and deliver more value to consumers,” Mr Broad said.

Last year Snowy Hydro contracted 888 megawatts (MW) of wind and solar projects which gave us incredible insights into energy pricing. This process confirmed many of the assumptions of Snowy 2.0’s business case, including that the National Electricity Market (NEM) has passed a tipping point. New renewables are now the most economic form of new generation, even when firmed by hydro or gas.

Snowy Hydro existing fast-start assets, and increased capacity with Snowy 2.0, will firm up large amounts of intermittent renewables by coming in and out of the system to ‘fill the gaps’ by generating energy at times of peak demand.

Snowy Hydro has a strong track record when it comes to pumped-hydro. For decades we’ve been successfully operating our pumping capability at Tumut 3 and that has been invaluable, especially in years of drought.

Snowy Hydro is the fourth-largest energy player in the NEM, providing much-needed competition in the market. Snowy 2.0, along with other developments, is adding to a portfolio that operates efficiently and reliably in a highly unpredictable NEM to maximise competition and drive the best outcomes for consumers.

Snowy 2.0 Exploratory Works will start immediately. The project is expected to generate up to 5000 jobs over the life of the project.

Sharing Snowy Stories

19/03/2018

As Snowy Hydro embarks on an expansion of the Snowy Scheme a unique digital storybook project is underway to capture the voices and experiences of ten former workers.

Snowy Hydro and Woden Community Service have partnered on the project which sees former workers who are all in their 80s and 90s share their stories of determination, success and resilience with current and future generations.

Paul Broad, Snowy Hydro’s Chief Executive Officer, said that former Snowy Scheme workers overcame significant engineering and construction challenges to build one of the greatest and most complex hydro power systems in the world.

“It took ingenuity, dedication and hard work to build the Snowy Scheme. Our former workers are a critical part of our company’s history and strength, and capturing their stories is very important.

“We often reflect on and marvel at the achievements of the original Snowy pioneers. Today, as we’re designing and planning the Snowy 2.0 project we’re grateful to have the expert records and technical data from the workers who came before us”, Mr Broad said.

Woden Community Service in collaboration with PhotoAccess and Gen S Stories have the privilege of working with the former workers and bringing their stories to life.

Chris Redmond, CEO of Woden Community Service, said the idea for this project grew from a senior’s social group for ex-Snowy workers, set up by Woden Community Service in August 2016.

“The group is led by Sandy Van Der Toorn, our Seniors Social Group Coordinator. Sandy’s father worked on the Snowy Scheme and she has many fond memories of growing up there.

“We’re also very lucky to have the expertise of Jenni Savigny from Gen S Stories on this project. She enables people of all ages to use the medium of digital storytelling to share their story and assists them to tell it in their own voice (literally). We look forward to working with Snowy Hydro to make this project a success”, Mr Redmond said.

Snowy Hydro has provided $25,000 to fund the project which is due to be complete in the middle of this year. A formal premiere of the stories will be held in June 2018.

Snowy 2.0 Feasibility Study Delivered

20/12/2017

Snowy Hydro’s independent Board of Directors has approved the Snowy 2.0 feasibility study, and for further work to be undertaken for the project to progress to a final investment decision in 2018.

The feasibility study released today confirms that the Snowy 2.0 pumped hydro expansion project is both technically and financially feasible.  The comprehensive study provides a base case design and a strong investment case that exceeds Snowy Hydro’s stringent investment hurdles, with significant input from leading experts in economics, engineering and geology.

Snowy Hydro’s CEO, Paul Broad, said that progressing Snowy 2.0 was a strategic business decision and the projected return on investment would enable the company to fund the project.

“Snowy Hydro already plays a critical role in keeping the lights on but Snowy 2.0 would supercharge our existing capabilities by adding an additional 2,000 megawatts of dispatchable generation and 350,000 megawatt hours of large-scale storage.

“Snowy 2.0 will underpin the security and reliability of the National Electricity Market (NEM) as we transition to a low emissions future, at least cost to consumers.

“As coal-fired generation retires and renewables continue to grow, Snowy 2.0’s scale and central location will provide secure and reliable energy generation and the necessary large-scale storage to prevent blackouts and lower future energy prices.

“Snowy 2.0 is a strategic long-term investment in the NEM that will firm up future wind and solar generation.  Intermittent renewables underpinned by Snowy 2.0 is a combination that could replace baseload generation when coal-fired power stations retire,” Mr Broad said.

The feasibility study outlines:

  • A strong investment case for the project and funding strategies.
  • A base case technical design, to be further refined as the project moves to final investment decision.
  • The independent estimation of costs between $3.8 – $4.5 billion, which takes into account the need for extensive reinforcement of the project’s structures due to the challenging geological conditions that were uncovered during the geotechnical drilling program.
  • If Snowy 2.0 is not built, the NEM would need a combination of batteries and gas peaking stations to meet future energy needs.  This would cost at least twice as much as Snowy 2.0.
  • A project schedule that will see the first power generated from Snowy 2.0 in late 2024, in time to meet market needs.

“Completing this study is a significant and exciting milestone for us but it’s only just the beginning. The sheer size of Snowy 2.0 makes it a complex and significant project that will put the Snowy Mountains back in the global spotlight,” Mr Broad said.

Between now and final investment decision, Snowy Hydro will undertake further work including additional geotechnical drilling, issuing project tenders, finalising funding for the project and working through well established and rigorous environmental and planning approval processes.

The project will also boost economic activity across the Snowy Mountains from employment opportunities across the supply chain and in supporting services.

Snowy Hydro would like to acknowledge the work of our lead study engineer SMEC Australia and the Australian Renewable Energy Agency for their contributions to the study.

Snowy’s highest power station to reach new heights

10/11/2017

Snowy Hydro, working with Andritz Hydro, is about to commence detailed design work for the replacement of the generator in unit one at Guthega Power Station. After more than 60 years of reliable operation this is the first time any generator across the Snowy Scheme has needed to be replaced.

The generator is connected to the turbine and is the part of the machine that converts the power produced by the spinning turbine into electrical energy for consumers. This project is certainly not your average flat pack. The generator will be assembled from thousands of individual pieces and weighing in at 230 tonnes it will need specialised trucks and trailers to get it on site.

Paul Broad, CEO of Snowy Hydro said this $13 million replacement project was the latest example of the company’s strategic investment in the Snowy Scheme.

“It’s not just Guthega Power Station we’re investing in. We have a thorough asset maintenance and modernisation program that upgrades our power stations and the water infrastructure across the Snowy Scheme.

“We’ve undertaken asset improvements that have actually increased the Scheme’s total generation capacity”.

“We’ve also implemented new technologies that allow us to start our generators faster, respond more quickly to changing market conditions and run our power stations remotely through our central control centre”, Mr Broad said.

The new generator will have a higher design rating (40 megawatts) than the existing unit to match the previously upgraded turbine. Every generator across the Scheme can be used independently and therefore each unit wears differently and is replaced based on its condition rather than age.

After undertaking a competitive tender process Snowy Hydro appointed Andritz Hydro to undertake the design, fabrication, install and commissioning of the generator. Andritz Hydro is a global supplier of electromechanical systems and services for hydropower plants and hydraulic power generation. The detailed design process and unit fabrication is expected to take around 12 months.

The Guthega Power Station houses two 30MW hydro-electric generating units and was the first power station built with construction starting in 1951. It’s on the Snowy River, just 12 kilometres from the summit of Mount Kosciuszko and sitting at 1330 metres above sea level, it is the highest power station in the Snowy Scheme.

National Science Week Competition

14/08/2017

‘The Science of Snowy’

As part of National Science Week this year, Snowy Hydro is running a ‘Science of the Snowy’ competition for Snowy Mountains students in years 3-6.

Paul Broad, Chief Executive Officer, said that National Science Week was a great opportunity for students to learn more about the science and engineering aspects of the Snowy Scheme.

“The construction of the Snowy Scheme was one of the civil engineering wonders of the modern world and from our pioneering past, we have grown into a modern and innovative energy company,” Mr Broad said.

To enter the competition just tell us your favourite science, technology or engineering fact about the Snowy Scheme. Your entry can be in words, pictures, a drawing or even a video.

Mr Broad said his favourite fact is that the Snowy Scheme acts like Australia’s biggest battery.

“While the Snowy Scheme may not look like a typical battery, it acts just like one. In the same way as a battery stores energy, the Snowy Scheme stores water which can be quickly used to create energy when it’s needed”, Mr Broad said.

Each winner will get two tickets to a VIP tour of the Snowy Scheme (including a power station) with some of Snowy Hydro’s very own scientists and engineers.

All winning and highly commended entries will also be displayed in the Snowy Hydro Discovery Centre in Cooma.

The competition is open to students at schools within the Snowy Valleys Council and Snowy Monaro Regional Council regions and in years 3-6.

The ‘Science of the Snowy’ competition opens on 14 August 2017 and closes at 5pm on 22 September 2017. An independent panel of judges will select the winners, with the panel to be announced shortly.

Snowy 2.0 activities adjacent to the Snowy Mountains Highway

03/08/2017

Over the coming weeks there will activities conducted as part of the Snowy 2.0 feasibility study adjacent to the Snowy Mountains Highway, about 12km north of Kiandra.

This work includes preparing for and undertaking investigative geotechnical drilling and you may see some trucks in and around the area.

At times there will be work on both sides of the highway and activity will be underway both during the day and at night.

The work involves drilling small core holes so we can better understand the rock underneath and inform the feasibility study. Approvals for the work was provided by National Parks and Wildlife Services after Snowy Hydro conducted a thorough environmental assessment.

Snowy Hydro takes safety very seriously and drivers are asked to exercise caution in the area. A traffic management plan will also be in place although we expect the any impacts on traffic to be minimal.

Visitors in Cooma ahead of drilling for Snowy 2.0 commencing

28/06/2017

The Prime Minister, Malcolm Turnbull, Deputy Premier John Barilaro and Parliamentary Secretary Bronnie Taylor visited Cooma today ahead of investigative drilling commencing for Snowy 2.0.

Snowy Hydro Limited CEO Paul Broad and Snowy Mountains Engineering Corporation (SMEC) CEO Andy Goodwin provided a Snowy 2.0 update and showcased one of the drill rigs.

Mr Broad said the investigative drilling, which is expected to commence next month after all approvals, is a critical milestone for the Snowy 2.0 feasibility study.

“The drilling will provide us with detailed geotechnical information about the rock formations, strength and structure of the area where the tunnels between the Tantangara and Talbingo reservoirs and underground power station will be located.”

“The core holes will be drilled in key locations so that we have a very clear picture of the geology and can better plan and cost the project.” Mr Broad said.

The geotechnical information collected through this process will be shared with research and education institutions for science and research purposes.

The Prime Minister, Deputy Premier and Parliamentary Secretary’s visit was also an opportunity for Snowy Hydro and SMEC to bring together their local project teams to celebrate the reopening of the SMEC office in Cooma.

SMEC’s CEO Andy Goodwin said the reopening of their Cooma office and work on the Snowy 2.0 feasibility study will continue to generate economic activity in the region.

“It’s great to be working on such a iconic hydropower project with Snowy Hydro that reflects on our namesake and history. For SMEC this is an opportunity to bring back our local people with global experience to contribute to the legacy for the next generation.

“The Feasibility Study will generate more than 250 jobs across professional services, construction and administrative support and if Snowy 2.0 goes ahead we expect to create about 5000 jobs over the life of the build,” Mr Goodwin said.

The Snowy 2.0 Feasibility Study will be completed by the end of this year.

Snowy Hydro is proud to provide secure, stable and reliable renewable energy to households and businesses. If built, Snowy 2.0 would increase the generation capacity by up to 50 per cent, making up to 2000 megawatts available to the National Electricity Market.

Snowy Hydro briefs industry on Snowy 2.0

15/06/2017

Snowy Hydro Limited (SHL) held an industry briefing in Sydney today for a large group of representatives of leading construction and engineering firms on the Snowy 2.0 pumped hydro project.

The industry briefing was told that SHL’s feasibility study was in full swing, with plans in place for geotechnical tests to begin shortly. While it was still early days, the company felt optimistic about the viability of the project and all going well, construction could begin in 2018, subject to the outcomes of the feasibility study.

SHL CEO Paul Broad told the briefing that the Finkel Review’s recommendations of a new Clean Energy Target and Regional Security Obligation offered major opportunities for the Snowy 2.0 pumped hydro project.

Mr Broad said there would be a strong increase in the use of intermittent power in the market – wind and solar – that would require reliable and rapid back-up supply of renewable energy. Snowy 2.0 would help further strengthen the critical role that SHL currently plays in ensuring system security and reliability.

“We are already the largest and most reliable battery storage option for the National Electricity Market. With Snowy 2.0, we will be able to provide an extra 2,000 MW of new renewable capacity and provide increased energy security and stability. This will be crucial as Australia transitions to a low-emissions economy over the next 20 to 30 years,” Mr Broad said.

Mr Broad said the importance of the Snowy 2.0 project was apparent from the participation today by key representatives of leading global and local civil engineering, tunnelling and electrical experts.

“There was strong support for the project from the leading industry players who attended the briefing today, and who are keen to partner with us to deliver this exciting project.There has been nothing like this in Australia since Snowy was completed in the 1970s and we want the best people available to assist us,” Mr Broad said.

Snowy Hydro advised industry that it would be undertaking a three-stage process to procure two packages of services, with one covering civil works and the other electrical/mechanical works.
Expressions of Interest would be called for shortly, with selected suppliers to be shortlisted for an Early Contractor Consultation Phase by late July.
