Notes
Plant-specific project cost was found for the broader Haughton Solar Farm 2 and BESS project, which includes both a 300 MW solar farm and a 200 MW / 2-hour BESS. The reported capital expenditure appears to cover the combined project, not the BESS alone; capex_per_mw_aud and capex_per_mwh_aud are therefore blended estimates based on the full project cost and registered BESS capacity. No separate BESS-only greenfield capex was found. O&M values for battery storage were not independently verified for this site; fallback defaults retained.
