UGL, in collaboration with Transgrid, is leading the design and construction of the Snowy 2.0 Transmission Connection Project (STCP) for Lumea. This initiative aims to seamlessly integrate the Snowy 2.0 project into the National Electricity Market (NEM), facilitating the distribution of up to 2,000 megawatts of renewable energy when demand is at its peak.
The core of STCP involves the construction of nine kilometres of high-voltage transmission lines across the Tumut River, connecting to a 330kV switching station nestled in the Bago State Forest. Originating from the Snowy 2.0 cable yard at Lobs Hole in Kosciuszko National Park, these transmission lines will span across the Talbingo Reservoir, ending at the Maragle switching station adjacent to Transgrid's Line 64.
As the project is based in the remote Kosciuszko National Park, there is no access to mains power.
To solve this problem the team invested in a 45kVA solar hybrid generator. The generator supplies energy to project offices and crib facilities. Key data was gathered over 292 days highlighting the following results:
- a 78.4% reduction in fuel consumption and
- 22,243kg CO2e reduction compared to a conventional diesel generator of similar capacity.
The project is also future proofing the high voltage transmission lines by equipping them to handle increased energy volumes if the Snowy Scheme's generation capabilities are expanded. This forward-thinking strategy involves incorporating special technology in the electrical conductor, ensuring adaptability to evolving energy needs.
“UGL’s STCP team is looking forward to delivering part of an iconic project that will provide sustainable and reliable energy to Australians for many decades to come.” Tim McCarthy, UGL Project Manager.
UGL's commitment to excellence and innovative solutions in the Snowy 2.0 Transmission Connection Project marks a significant stride towards a sustainable and resilient energy future for the national electricity market.
