Technical FAQs 4

Are battery energy storage systems a fire hazard mitigation strategy?

The challenges of providing effective fire and explosion hazard mitigation strategies for Battery Energy Storage Systems (BESS) are receiving appreciable attention, given that renewable energy production has evolved significantly in recent years and is projected to account for 80% of new power generation capacity in 2030 (WEO, 2023).

Where should the energy storage system be located?

All Energy Storage System installations shall be located at the same storey as the fire engine accessway/ fire engine access road. c. The allowable Maximum Stored Energy for the various battery technologies in each compartment shall be as listed in Table 10.3.1. a It shall refer to an aggregated stored energy capacity per compartment.

What is the new battery storage guideline?

The new guideline sets a clear standard for how battery storage systems should be installed to minimize the risk of fires and other incidents. The guideline is specifically designed to provide practical guidance for the installation of batteries in both commercial and residential buildings, as well as in free-standing outdoor structures.

What happens if the stored energy capacity exceeds the limit?

Where the stored energy capacity or separation distance of the unit exceed the limit, it shall be subjected to the fire and explosion testing specified under UL 9540A and together with the NFPA 855 Hazard Mitigation Analysis report to be submitted to SCDF for approval.
