A joint venture between Windlab and Squadron Energy has submitted the Bungaban Solar Project, comprising a 500 MW solar PV facility and a 500 MW battery energy storage system (BESS), to Australia’s federal government for assessment under the Environment Protection and Biodiversity Conservation (EPBC) Act. The EPBC Act referral also covers a transmission line that would link the solar and battery facilities to Powerlink’s proposed Warranna substation, which forms part of the separate Bungaban wind park connection project. Construction is scheduled to commence in July 2028.
The referral was submitted by Bungaban Hold Trusco, a 50/50 joint venture between Federation Asset Management, the sole owner of Windlab, and Squadron Energy, which was established in April 2026. Windlab had previously been solely responsible for developing the solar and storage component.
With its 500 MW BESS, the project would rank among the larger co-located battery storage developments currently progressing through Australia’s federal approval process. It also reflects the growing pipeline of solar-plus-storage projects in which battery capacity is designed to closely match, or equal, the associated generation capacity, rather than serving as a smaller firming component (Energy-storage.news, 20/08/2026).
