King Island to host big battery storage system

An Australian energy storage company Ecoult has been awarded the Hydro Tasmania contract to supply King Island with the largest battery-based renewable energy storage system in Australia.

The 3 MW/1.6 MWh UltraBattery storage system will complement other elements of Hydro Tasmania’s King Island Renewable Energy Integration Project (KIREIP). This projects aims to significantly reduce the island’s reliance on diesel fuel to supply its energy needs. The storage system will have the capacity to power the entire island for up to 45 minutes.

Ecoult CEO John Wood said the UltraBattery storage system, a CSIRO invention, would shift and smooth renewable energy generated on King Island and will help maintain stability of the power grid. An UltraBattery is a supercapacitor integrated with a lead–acid battery.
