Battery storage
A Battery Energy Storage System (BESS) is collection of battery modules, inverters and power systems that work together to capture, store and discharge electricity from the network. BESS technology plays a role in storing excess power during low demand periods and redistributing that power during peak demand periods.
Frequently Asked Questions about Battery Energy Storage System (BESS)
Are BESS’ safe?
Yes, BESS use lithium-ion technology, which is the same battery composition used in mobile phones, laptops, handheld battery powered tools, and other everyday devices. BESS are a larger scale system, so therefore more lithium-ion is required.
As part of its development approval, a Preliminary Hazards Assessment has been completed for the Blackstone BESS, which evaluates likelyhood of a failure and safety requirements in the event of a failure
Are there fire risks associated with BESS?
Fire is an inherent risk for any electrical system. To ensure that fire, specifically relating to lithium-ion technology is mitigated, Octopus Australia will adhear to all Fire Management requirements under the development approval of the Blackstone BESS.
This includes but is not limited to, fire detection systems, standalone firefighting water tank, and adhering to bushfire risk mitigations during construction or operational works (e.g hot works permits, or total hot works ban)
Do BESS’ make noise?
Noise from BESS projects generally result from the fans / cooling system used to ensure the battery cells remain in their optimal operating temperature. These cooling systems operate when the BESS is charging / discharging
As part of the development approval, Blackstone BESS has completed a Noise Impact Assessment, and will remain compliant with maximum sound levels.
Decommissioning / end of project life, who is responsible?
Decommissioning is the responsibility of the Blackstone BESS owner (i.e. Octopus Australia). A detailed decommissioning plan will be submitted to the relevant local and state government planning authorities prior to de-construction of the BESS can commence.
If there is an opportunity to extend the operating life of the project through replacing BESS units with newer BESS unites (“repowering”), a new development approval application will be submitted to local and state government planning authorities.
