A new transmission connection and substation is proposed to connect Snowy 2.0 to the National Electricity Market (NEM).
Snowy 2.0 is a pumped hydro expansion of the existing Snowy Scheme planned by Snowy Hydro Limited with an anticipated capacity of 2000 megawatts.
Why is a connection necessary?
New generation assets need to be connected to the transmission network to be able to operate within the NEM. Snowy 2.0 requires this transmission and substation connection to connect their generation into the existing transmission network to therefore unlock the full capacity of the Snowy 2.0 project.
What is Transgrid proposing?
Transgrid is proposing to construct and operate a dual 330kV double circuit overhead transmission connection and substation to meet the grid connection requirements of Snowy 2.0.
The two lines would be side-by-side, spanning from the Snowy 2.0 generator site through Kosciuszko National Park to the new substation located in Bago State Forest, adjacent to Transgrid’s existing Transmission Line 64.
The length of the connection is approximately 9 kilometres.
