Kwinana Battery Energy Storage System


Synergy, Western Australia's state-owned electricity generator and retailer, and NHOA selected Genus for the on-site EPC delivery of a 100MW/200MWh battery storage facility to be located at the Kwinana Power Station site, to provide additional security and stability to Western Australian’s power system.
Stage 1 of the Kwinana Battery Energy Storage System (KBESS1) project represents the first major grid-connected battery energy storage system in Western Australia, a major step in the commitment of the state government to facilitate the integration of renewables on the grid for a cleaner future as part of the Energy Transformation Strategy.
The Kwinana system will absorb excess renewable generation and will provide essential system services to stabilise the grid.
The Kwinana Battery Energy Storage System project was delivered on a full engineering, procurement and construction (EPC) basis, along with onsite installation and interconnection of the system.
