Estimated $ per interval — energy (RRP) and FCAS (regional FCAS prices), both × MLF.

Methodology & assumptions

Dispatch & availability — AEMO Next Day Dispatch UNIT_SOLUTION (5‑minute intervals). Intervention intervals excluded.
Regional price — dispatch_price RRP matched by settlement time and NEM region (from generator registry).
Energy revenue (× MLF) — cleared MW × (5/60 h) × RRP × MLF.
FCAS revenue & volume — cleared FCAS MW from DISPATCHLOAD (raise/lower 6s, 60s, 5min, reg) × (5/60 h) × regional FCAS price × MLF. Volume is total FCAS enablement MWh across services.
Curtailment — estimated economic curtailment when availability exceeds dispatch target: max(0, availability − cleared) × (5/60) MWh.
Not settlement — estimates only. AEMO settlement applies DLF, rebids, constraints, and other factors not modelled here.

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)	$182.28M Shown in table $182.28M (2026 real AUD) Reported / source value $172.80M (2024 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups).
Capex refurbishment	—
Capex / MW derived	$4,219,409 Shown in table $4.22M (2026 real AUD) Reported / source value $4.00M (2024 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups).
Fixed OPEX (annual)	—
Fixed OPEX / MW-yr default	$40,000 Shown in table $40.0k (2026 real AUD) How this was derived AEMO/Aurecon includes hydro-electric schemes in its technology-cost dataset, but the accessible excerpts here did not expose a Fisher-specific fixed O&M value. Reference 2024 Energy Technology Cost and Technical Parameter Review (medium confidence) Source recorded 07 Jun 2026
Variable OPEX / MWh	$1.05 Shown in table $1.05 (2026 real AUD) Reported / source value $1.00 (2024 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups). How this was derived User-provided internal technology default retained because no plant-specific variable O&M was found in the searched sources.
Fuel cost / GJ	— How this was derived Hydro stations consume water flow rather than purchased fuel. Reference Mersey-Forth (high confidence) Source recorded 07 Jun 2026

Notes
Plant-specific greenfield capex for Fisher was not found in the searched official owner/government sources. Hydro Tasmania states the Mersey-Forth scheme (which includes Fisher) was commissioned in 1972, and the Fisher power station entry in Hydro Tasmania's Mersey-Forth water management review shows Fisher commissioned in 1973 with 46 MW. Hydro Tasmania also states the final power station in the Mersey-Forth upgrade sequence is Fisher, with works due to start in 2027. A plant-specific refurbishment cost for Fisher was not located; the 2026 Mersey-Forth upgrade context suggests refurbishment may be forthcoming, but no Fisher-specific cost was identified in official sources.
