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)	$107.07M Shown in table $107.07M (2026 real AUD) Reported / source value $104.50M (2025 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups). How this was derived No Derby-specific total project cost or construction investment figure was found in the sources searched.

Capex / MW	$1,127,049 Shown in table $1.13M (2026 real AUD) Reported / source value $1.10M (2025 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups).
Fixed OPEX (annual)	$1.75M Shown in table $1.75M (2026 real AUD) Reported / source value $1.71M (2025 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups).
Fixed OPEX / MW-yr	$18,443 Shown in table $18.4k (2026 real AUD) Reported / source value $18.0k (2025 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups). How this was derived No project-specific fixed O&M source was found; server-side default used.
Variable OPEX / MWh	$0.20 Shown in table $0.20 (2026 real AUD) Reported / source value $0.20 (2025 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups). How this was derived No project-specific variable O&M source was found; server-side default used.

Notes
No plant-specific greenfield capex figure was found in the searched owner/developer, government, or project sources. Public sources confirm the project as a 95 MW solar farm with battery storage, but the available search results only reference a broader Victorian project portfolio investment figure ($1.48 billion across six projects) and not a Derby-specific total project cost. AEMO/CSIRO GenCost was not used for capex because project-specific capex remains unfound. O&M defaults were applied only where no project-specific O&M data was found.
