Estimated capex, local spend and peak workforce
Total development cost
unknown unknown
Transmission capex is route-specific — benchmark estimate not derived. See proponent/Transgrid statements.
Estimated local / regional spend
unknown unknown
Local spend not estimable without a capex figure.
Estimated peak construction workforce
unknown
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.

Focus on consumer energy resources (rooftop solar + community batteries), spare government land + commercial roofs, green hydrogen + green steel manufacturing. MoU with Endeavour Energy on network and battery solutions.

Includes potential green steel manufacturing, hydrogen.
Notes
Smallest declared NSW REZ at 1 GW network capacity. Distinct character from other REZs: distributed generation focus, community batteries, integration with existing Port Kembla/Dapto industrial infrastructure. Federal Illawarra offshore wind component (separate parallel declaration) has been paused — see prj-ill-offshore-wind.
