Kwinana Battery Energy Storage System Stage 2 (KBESS2)


Genus has been awarded a contract by Synergy to perform the Civil and Electrical Balance of Plant works (BOP Works) for the KBESS2 250 MVA/1000 MWh battery storage facility located in Kwinana.  The contract including early works has an approximate value of $90 million.  The contract is scheduled for completion by the end of 2024.

KBESS2 has four times the storage capacity of the recently completed KBESS1.  This project is part of the Western Australia State Government’s decarbonisation strategy including its commitment to retire State-owned coal power stations by 2030.  KBESS2 will support the ongoing growth in distributed solar generation and the connection of largescale renewable generation assets to the network.
