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.

Tallawarra Power Station — EnergyAustralia
https://www.energyaustralia.com.au/about-us/energy-generation/tallawarra-power-station ↗
316 MW dual-fuel (natural gas + hydrogen) open-cycle gas turbine. First Australian power station designed to use green hydrogen as part of its fuel mix. Operational since Aug 2023. Adjacent to Tallawarra A (435 MW CCGT).

Notes

Gas peaker, not a renewable generation project — but tracked because Tallawarra B is the first Australian power station designed to use green hydrogen as part of its fuel mix and sits squarely inside the declared Illawarra REZ. Relevant to the Illawarra REZ's green-hydrogen / industrial-decarbonisation narrative. Technology classified as 'other' (gas/H2 hybrid) rather than as wind/solar/BESS.
