Proposed grid-connected battery energy storage system rated at 450 MW / 1,800 MWh / 4 hours, with an on-site substation and O&M building. The referral describes planned overhead transmission lines to the Lower Tumut Switching Station; connection type is subject to Transgrid requirements. Associated works include upgrading the Miles Franklin Drive–Snowy Mountain Highway intersection. The referral gives Project Areas A+B as 30.10 ha, a 21.86 ha disturbance footprint and an 8.24 ha avoidance area; it notes these area calculations differ very marginally from the EPBC portal calculations because of GIS software differences.
