Notes
I could confirm the project is proposed at Glenbawn reservoirs under WaterNSW / AGL, with current design of 770 MW and 10-hour storage (7,700 MWh). I did not find a plant-specific greenfield capex announcement for Glenbawn, so no capex total was populated. WaterNSW and AGL materials describe the project as early-stage / proposed, and WaterNSW notes geotechnical investigations are expected to start in November 2025, indicating it is not yet commissioned.
