Notes
No project-specific greenfield capex announcement was found for Great Lakes Battery in owner or government sources. The project website states the battery will be up to 280 MW / 560 MWh and privately financed by Neoen, with construction expected to take around 18 months once commenced. The website also states battery technology typically has an industry-leading 20-year warranty. In the absence of a plant-specific capex figure, no benchmark capex has been inserted here because the request prioritised project-specific sources and asked not to use AEMO benchmarks unless necessary.
