Notes
No plant-specific greenfield capex or commissioning date was found in the searched official/project sources. Akaysha’s project page confirms Halys BESS is a proposed project of up to 1000 MW / 2000 MWh adjacent to Halys Substation in Queensland, but does not disclose project cost. Because no verified project-specific investment figure was found, capex remains unset rather than inferred from benchmarks. O&M values fall back to the provided internal defaults pending a sourced battery benchmark or project-specific estimate.
