Financial overview

2026 real AUD. Monetary values are CPI-adjusted to 2026 real Australian dollars. Greenfield capex uses AEMO benchmarks when plant-specific cost is unknown.

How this was derived
Aurecon provides benchmark EPC cost components for a 4-hour, 200 MW large-scale lithium-ion BESS with dedicated grid connection. These were scaled to the user's 65 MW / 260 MWh capacity because project-specific capex was unavailable.

Capex / MW
$1,621,000

How this was derived
For a 4-hour system, AUD 525/kW plus 4 hours * AUD 274/kWh equals AUD 1.621 million per MW of power capacity.

Capex / MWh storage
$405,250

How this was derived
The benchmark 4-hour BESS cost of AUD 1.621 million/MW is equivalent to AUD 405,250/MWh of storage energy capacity.

Fixed OPEX (annual)
$1.38M

How this was derived
The annual fixed opex estimate scales Aurecon’s AUD 21,200/MW-year benchmark by the user's 65 MW capacity.

Fixed OPEX / MW-yr
$21,200

How this was derived
Aurecon separates fixed O&M and warranty; both are included here as fixed annual opex because warranty cost is needed for the assumed 20-year BESS life.

Variable OPEX / MWh
$0.00

How this was derived
Variable O&M is treated as zero/not separately modelled; BESS opex is represented through fixed O&M and extended warranty costs.

Heat rate GJ/MWh
—

How this was derived
Heat rate is not meaningful for electrochemical storage; round-trip efficiency is the relevant operating efficiency metric.

Notes
No public generator-specific construction cost, EPC contract value, O&M contract, variable O&M contract, financing close, DUID, or commissioning date was found. The user's supplied 65 MW / 260 MWh capacity conflicts with current public project pages: ANZA Power and Bison list 50 MW / 200 MWh, while a June 2023 Bison interview referred to 60 MW / 240 MWh. Financial values are therefore estimates scaled to the user's supplied 65 MW / 260 MWh from AEMO/Aurecon 2025 large-scale lithium-ion BESS benchmarks for a 4-hour, dedicated-grid-connection project. Estimated capex uses Aurecon 4-hour BESS power component AUD 525/kW plus energy component AUD 274/kWh: 65,000 kW * 525 + 260,000 kWh * 274 = AUD 105.365 million EPC cost. This excludes any site-specific network augmentation, owner’s costs not captured by the benchmark, financing costs, contingency beyond the benchmark basis, and project-specific connection risks. Fixed opex uses Aurecon 4-hour fixed O&M AUD 12,800/MW-year plus extended warranty AUD 8,400/MW-year = AUD 21,200/MW-year. Variable O&M is set to 0 because Aurecon reports BESS long-term service agreements are not typically fixed/variable split. Efficiency is beginning-of-life round-trip efficiency at point of connection. Operational Scope 1 emissions are treated as zero because the BESS has no onsite fuel combustion; lifecycle and charging-energy emissions are not included. Major refurbishment/closure: public sources show the project as under development; no closure notice was found. For generic BESS life, Aurecon states 20-year design/technical life, potential extension to about 25 years after condition assessment, and further extension with battery upgrades.
