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.

Capex total (greenfield)
$4,585.15M

Shown in table
$4,585.15M (2026 real AUD)

Reported / source value
$4,200.00M (2023 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Included for transparency, but this is not attributable solely to Richmond Valley BESS and therefore was not used as capex.

Table total may differ if recalculated from $/MW × registered capacity after CPI adjustment.
Fixed OPEX / MW-yr

Shown in table
$17.5k (2026 real AUD)

Reported / source value
$16.0k (2023 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
For the 8-hour battery case, the table shows fixed O&M of $16,000/MW-year for the base LFP BESS case used here.

Variable OPEX / MWh
$1.64

Shown in table
$1.64 (2026 real AUD)

Reported / source value
$1.50 (2023 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
The AEMO/Aurecon benchmark does not specify a separate variable O&M for BESS LTSA-style projects; the internal fallback of 1.5 AUD/MWh is retained as a conservative placeholder.

Notes
No plant-specific greenfield CAPEX for Richmond Valley BESS (EIWA) was found in the searched owner/government sources. Ark Energy's Richmond Valley Solar & BESS pages describe the project and size, and the NSW Government/AEMO Services tender notice confirms the BESS was awarded an LTESA, but none of the located sources state a battery-only project capital cost for the EIWA/Richmond Valley BESS unit. O&M and technical assumptions use AEMO/Aurecon 2024-25 battery storage benchmark inputs: 8-hour BESS fixed O&M $16,000/MW-year, variable O&M not typically charged separately for BESS LTSA-style projects, 20-year design life, and ~90% round-trip efficiency for LFP batteries. The project is larger than the 300.3 MW DUID capacity stated by the user in internal data; no source-backed storage duration was located in the searched results, so per-MWh capex could not be derived.
