Estimated capex, local spend and peak workforce
Total development cost
~$1.18B benchmark estimate
1680 MWh × $0.7M/MWh (BESS)
Industry benchmark only — not project-specific. Sources: Clean Energy Council, BloombergNEF 2024 Australian utility-scale LCOE inputs, AEMO ISP 2024 cost assumptions. Actual capex varies materially by site, OEM, supply chain and grid-connection works.
Estimated local / regional spend
~$259M benchmark estimate
22% of capex — Clean Energy Council benchmark for renewable energy construction in regional Australia. Actual local content varies by project siting, procurement strategy and any access-scheme local-content conditions.
Estimated peak construction workforce
~672 roles benchmark estimate
Industry benchmark: ~0.7 FTE/MW wind, 0.5 FTE/MW solar, 0.4 FTE/MWh BESS, 1.5 FTE/MW pumped hydro. Peak during civil/electrical phase only — operations workforce is typically ~5-10% of construction peak.
Workforce breakdown — sector mix and phasing

Sector mix and phase distribution for the estimated construction workforce. Basis: industry norm (Clean Energy Council, ARENA, AEMO ISP 2024 + comparable EIS Social Impact Assessments). Numbers are decision-support indicators, not a project-specific forecast.

By phase (across construction window)
PhaseFTEWhat's happening
Mobilisation + civils (year 1)
~403
Site prep, access roads, foundations, early electrical. Civil trades dominant.
Peak construction (year 2)
~672
All trades concurrent. Turbine / panel delivery, electrical install, commissioning prep.
Commissioning / demob (year 3)
~470
Specialist electrical and testing. Civil and structural ramping down.
Operations (ongoing)
~47
Permanent O&M workforce — typically 5–10% of construction peak. Plus periodic major-maintenance windows.

Sector mix from CEC, ARENA and AEMO ISP workforce profiles for utility-scale Australian builds. Phase distribution from comparable EIS Social Impact Assessments. Indicative only — actual workforce varies with OEM, contractor strategy, weather and OSOM scheduling.
