The Mundubbera Town 66/11kV substation has reverse power flow primarily from residential and commercial rooftop solar growth. To manage these flows, and the forecast significant growth into this and the wider zone substation network at ISIS 132/66kV Bulk Supply Point (BSP), Egis’ Energy team (formerly Peracon*) designed a Battery Energy Storage System (BESS).
Energy Queensland wanted to deliver this programme of work rapidly to meet the needs of the network. This was the first of 18 similar projects that the team has worked on.
*Peracon was acquired by Egis in March 2025.
