The Morrison government’s support for the historic Snowy 2.0 project continues to create jobs and opportunities for regional Australia.
Snowy Hydro today launched its new Snowy 2.0 precast plant in Cooma, where 130,000 concrete segments are produced locally to line the tunnels of the southern hemisphere’s largest pumped hydropower project.
Snowy 2.0, Australia’s largest new renewable energy project, will continue to keep the lights on for generations, providing reliable power to support record levels of new wind and solar power.
The $ 5.1 billion project is moving forward, creating jobs and significant economic benefits for the regions. Over 1,000 people are already working on the project, with 4,000 direct jobs expected over the life of the project. This includes more than 220 jobs during construction and operation of the segment plant.
Industry, Energy and Emissions Reduction Minister Angus Taylor says Snowy 2.0 will reduce market volatility, support reliability and lower electricity prices for families and businesses Australian.
“Snowy 2.0 will store excess energy from the world’s best levels of solar home energy in Australia and use that energy when the sun goes down, to keep the lights on and prices low as we continue to add record levels. of renewable energies to the grid “, declared the Minister. Taylor said.
âThe project is driving significant economic activity in the NSW region, not only through the thousands of jobs it will create, but also through the many local businesses that are already benefiting from Snowy 2.0.
âThis is a great example of regional manufacturing power, and today’s announcement is another milestone for Project Snowy 2.0. “
Snowy Hydro CEO and Managing Director Paul Broad said he was happy to see many locals employed at the plant as part of Snowy 2.0.
âFrom the start, we wanted to build this factory locally rather than importing segments from overseas or from state to state, as that meant local jobs, opportunities and investment,â Mr. Broad.
âIt is therefore with great pride that we celebrate the official launch of this essential installation for Snowy 2.0 alongside our prime contractor and operator of the Future Generation Joint Venture plant.
Plant operations include a concrete batching plant and two automated carousels, producing up to 24 rings, each made up of nine segments, per day.
Raw materials come from the region to mix the concrete within the concrete batching plant, which is then transferred to the plant and poured into specially designed molds every 10 minutes.
As part of a recycling initiative, approximately 70,000 tonnes of slag – a by-product of the steelmaking process – is used to produce the segments. This reduces the amount of cement needed by 40 percent.
The segments will power the three Snowy 2.0 tunnel boring machines as they dig and cover over 27 kilometers of tunnels between the Tantangara and Talbingo reservoirs.
The Lady Eileen Hudson TBM is excavating the main access tunnel (currently over 350 meters deep), and the second machine, TBM Kirsten, is being assembled, ready for commissioning and launched.
Context of the Snowy 2.0 project:
When complete, Snowy 2.0 will increase the capacity of the Snowy Hydro Scheme by 2,000 megawatts and provide 350,000 megawatt hours of full-scale storage, enough to power the equivalent of 500,000 homes for more than a week during peak demand.
This will reduce market volatility, support reliability and lower electricity prices for Australian families and businesses.
The Australian government has pledged $ 1.38 billion in equity for Snowy 2.0, with Snowy Hydro funding the remainder of the project.
Snowy 2.0 will link two existing Snowy Scheme reservoirs, Tantangara and Talbingo, with 27 km of river tunnels and a power plant with six pump-turbines located approximately 800 m underground.
The water in the upper storage will be released for power generation at times of peak demand and pumped out at times when there is excess power in the grid, so Snowy 2.0 is ready to meet the demand. request when needed.
Snowy 2.0 Segment Factory Facts
- 130,000 concrete segments will be produced at the plant to line the Snowy 2.0 tunnels.
- Up to 12 rings, each made up of nine segments, will be made per carousel each day.
- Over 14,500 rings will be produced in total, each 10 meters in diameter,
- To create the segments, the raw materials come from the region to mix the concrete in the concrete batching plant, which is then transferred to the plant and poured into specially designed molds every 10 minutes.
- Through the use of robotics, the molds progress along the carousel as the segments harden and finish. There is an on-site laboratory and testing to verify the quality of each product segment.
- It takes about eight to ten hours to harden and demould each segment from start to finish, then they are stored for about two weeks before being transported to site, loaded into tunnel boring machines and installed in tunnels.
- The first segment factory carousel began production in July 2021 and the second carousel in September 2021.
- With two carousels operating at peak production, 90 tonnes of concrete will be poured per hour.
- The robotic arms and hydraulic covers of the concreting station are key innovations and advanced technology involved in production.
- The total workforce for the concrete batching plant and segment plant at full capacity is approximately 110 people, many of these roles being filled by local people. About 120 people were employed to build the facility.
