Ecoult awarded largest battery-based renewable energy storage project in Australia; 1.6 MWh UltraBattery system
Australia-based Ecoult has been awarded a Hydro Tasmania contract to supply the largest battery-based renewable energy storage system in Australia for the King Island Renewable Energy Integration Project (KIREIP). Formed in 2007 by the CSIRO Australia to commercialize the UltraBattery (earlier post), Ecoult was acquired by the US-based East Penn Manufacturing Company Inc. in 2010.
The 3 MW / 1.6 MWh UltraBattery storage system will complement other elements of Hydro Tasmania’s KIREIP, the aim of which is to reduce significantly King Island’s reliance on diesel fuel to supply the island’s energy needs. The storage system will have the capacity to power the entire island for up to 45 minutes.

The UltraBattery combines the advantages of advanced lead-acid battery technology with the advantages of an asymmetric capacitor, enabling an optimal balance of an energy-storing lead-acid battery with the quick charge acceptance, power discharge, and longevity of a capacitor. UltraBattery operates very efficiently in continuous Partial State of Charge (PSoC) use without frequent overcharge maintenance cycles.
KIREIP will enable demonstration of a power system that can deliver more than 65% of the island’s annual needs from renewable energy, and do it without any loss of reliability or grid stability and at a price lower than the diesel power alternative. KIREIP will lower CO2 emissions by 95% through the use of sustainable clean energy sources, including bio-diesel.
