The proposed system will use enclosed lithium-ion or sodium-ion batteries with a total delivery of up to 50MW AC power output and 100MWh of storage capacity, which may be delivered in stages.
According to the EPBC Act application, the battery units will be manufactured off-site and delivered to the site following completion of ground preparation, which includes levelling and bench construction.
Construction is expected to take approximately 12 months, with the facility operating 24 hours a day, seven days a week for a design life of 20 years, extendable to 30 years through battery module replacement.
The disturbance footprint of 1.45 hectares comprises 0.57 hectares of native vegetation, including trees along Awaba Road; 0.49 hectares of exotic grassland; and 0.39 hectares of the existing cleared access track and substation area.
The EPBC submission notes that parts of the footprint have been historically cleared for the existing Ausgrid substation and an asset protection zone, meaning a portion of the vegetation present has already been degraded.
