Why do we need the project?
A direct connection to the transmission network is required for an expanded Snowy Hydro to connect to the electricity grid. The transmission line would also allow the Snowy 2.0 storage 'battery' to be charged during periods of low demand.
Snowy Hydro Limited has engaged TransGrid to deliver the connection that will enable it to provide an additional 2000MW of dispatchable, on-demand storage capacity.
What is TransGrid proposing?
Installation of two new double-circuit transmission lines from the Snowy Hydro 2.0 generator site in Kosciuszko National Park to a new switching station in Bago State Forest. The transmission lines would be around 9km long.
The switching station would be built next to TransGrid's existing transmission line connecting the Upper Tumut and Lower Tumut substations.
