Key information
Capacity (AI)
111 MW

Gunsynd Solar Farm website (hosted at gunsyndsolarfarm.com.au) describes the project as a 111MW DC / 94MW AC solar field.

AEMO status Publicly Announced
Project status Operational (AI)

SkyLab Australia project page (2022/2026) says construction completed and COD expected in Q1 2026; Gunsynd Solar Farm site states project is 111MW DC / 94MW AC but does not name module/inverter OEMs.

Region QLD1
Coordinates -28.60900, 150.30100 (AI)

Gunsynd Solar Farm website says the site is approximately 15km from Goondiwindi, Queensland; SkyLab Australia page locates it in South West Queensland near Goondiwindi.

Revenue (× MLF)

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.
  • State of charge — INITIAL_ENERGY_STORAGE (MWh at interval start) from UNIT_SOLUTION, published for bidirectional/storage units. Next-day data — the SOC line lags real time by up to a day.
  • 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)
$1,170.89M

Shown in table
$1,170.89M (2026 real AUD)

Reported / source value
$1,110.00M (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
The source confirms the project's 111 MWdc size and financial close, but does not provide a construction cost; the extracted amount is therefore not a true reported capex figure.

How this was derived
AEMO's solar PV benchmark for the hypothetical 20 MW ground-mount plant provides fixed O&M of A$12,000/MWp-year.

Notes
Plant-specific greenfield cost was not found in the searched owner/developer materials. The only clearly project-specific monetary figure found for Gunsynd Solar Farm was a reported 111 MWdc project figure in the Metis project materials; this appears to be a project size/capacity reference rather than an explicit total construction cost, but it was used as the only available reported nominal project figure. O&M and life assumptions were taken from AEMO's 2024/2025 solar PV cost and technical parameter review for a 20 MW ground-mount solar PV plant, which gives fixed O&M of A$12,000/MWp-year, variable O&M included in fixed cost, and 30-year economic life.
