Geranium Plains Solar and BESS

Notes
No project-specific greenfield capex announcement was found for Geranium Plains Solar and BESS in the searched official and reputable sources. AEMO documents confirm the project was proposed as 250 MW solar and 150 MW battery storage, but they do not provide capex. For battery operating assumptions, AEMO/Aurecon GenCost-style benchmark values for a hypothetical 200 MW Li-ion BESS were used as the closest available NEM reference: 4-hour BESS capex $313.3m total, fixed O&M $12,800/MW-yr, variable O&M nil, design life 20 years, and 1-2% EFOR with ~1.8% annual energy degradation. Because the site is a hybrid solar+BESS project and no project-specific battery duration or build cost was located, the capex fields remain unreported rather than estimated from benchmarks.
