Notes
I found a Recurrent Energy project page for Gunnedah BESS showing project capacity of 280 MWh, but no plant-specific greenfield investment/capex figure was located in the available sources. Because the prompt required plant-specific capex before falling back to benchmarks, capex is left blank rather than inferred from AEMO/CSIRO. For battery O&M, AEMO/Aurecon 2024 provides indicative fixed O&M of $5,400/MW-year for a 1-hour BESS and states variable O&M is typically not used for BESS long-term service agreements; extended warranty can add $3,600/MW-year for 20-year LFP batteries. A 20-year battery life is used as a technical default from the same source. No refurbishment cost identified.
