Notes
Pacific Blue stated the project is a $100 million, 60 MW / 130 MWh grid-scale battery at Clements Gap; this is a reported project investment figure. Later Pacific Blue material describes the battery as 60 MW / 120 MWh, so the reported cost is paired here with the announced 60 MW project capacity and the 2024 construction start year. Operational lifespan noted by Pacific Blue is 20 years.
