Notes
No plant-specific greenfield capex could be found in owner, government, or news search results. Using AEMO/Aurecon 2024 battery benchmark O&M only as fallback. Dederang BESS is an indicative 400 MWh project; planning permit issued 5 June 2025. If capacity is 200 MW / 400 MWh, benchmark O&M implies fixed O&M annual cost of AUD 10.2 million (51,000 AUD/MW-yr x 200 MW), but capex remains unreported.
