Notes
Genex states the project reached financial and contractual close in April 2021 with total funded construction cost of around A$777M. Genex also describes the project as 250MW for 8 hours (2,000MWh) and notes a project lifespan of 80 years. AEMO/Aurecon 2024 PHES and hydro review was used only as fallback context for operating assumptions; project-specific O&M data was not found.
