Setting up minimum separation from walls, openings, and other structural elements. The National Fire Protection Association NFPA 855 Standard for the Installation of Stationary Energy Storage Systems provides the minimum requirements for mitigating hazards associated with ESS of diferent battery types.
suppression equipment may or may not be provided as an integral part of an ESS, or it may be optional. Depending on the case, the ESS shall comply with all applicable performance requirements in the standard with and/or without the fire detection and fire suppression equipment in place and operational.
Water spray has been deemed safe as an agent for use on high-voltage systems. Water mist fire suppression systems need to be designed specifically for use with the size and configuration of the specific ESS installation or enclosure being protected. Currently there is no generic design method recognized for water mist systems.
Optimized power control allow significant reductions, e.g., in fuel and maintenance costs and emissions. In all applications, land or marine, ESS can provide the flexibility and freedom to store electrical energy and utilize the energy when it is most beneficial for system operation.
Depending on the case, the ESS shall comply with all applicable performance requirements in the standard with and/or without the fire detection and fire suppression equipment in place and operational. The guidance on capacity and separation distance limits given in Appendix E are aligned with those of NFPA 855 as given in Table 3.
The most practical protection option is usually an external, fixed firefighting system. A fixed firefighting system does not stop an already occurring thermal runaway sequence within a battery module, but it can prevent fire spread from module to module, or from pack to pack, or to adjacent combustibles within the space.
