Project Status
Location
Swallow Tail BESS is located on Gundungurra Country five kilometres east of Bannaby and 20 kilometres from Taralga.
The project is named after the nearby Swallow Tail Pass on the Tarlo River. The project will connect to the Bannaby substation, which is a key point on TransGrid’s 330kV transmission network connecting renewable energy resources from southern NSW to electricity consumers across NSW and beyond.
