Ecoult has been awarded the Hydro Tasmania contract to supply the largest battery-based renewable energy storage system in Australia for the King Island Renewable Energy Integration Project (KIREIP).

The 3 MW / 1.6 MWh UltraBattery storage system will complement other elements of Hydro Tasmania’s KIREIP, the aim of which is to significantly reduce 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.

Powered by Ecoult’s breakthrough UltraBattery® technology, the system will support the utilisation of renewable energy by storing energy in periods where there is excess generation and making it available when it is needed to better match demand. This will help maintain stability of the King Island power grid.

KIREIP will enable demonstration of a world-leading power system that can deliver more than 65 per cent 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 per cent through the use of sustainable clean energy sources, including bio-diesel.
