Snowy 2.0 Connection Project

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 is the client for this proposal.

What is TransGrid proposing?

Installation of two new double-circuit transmission lines from the Snowy Hydro 2.0 generator site to a new substation in Maragle. The transmission lines would be around 9km long.

The Maragle substation would be built next to TransGrid's existing transmission line in Bago State Forest. This line connects the Upper Tumut and Lower Tumut substations.
