Core requirements include rack separation limits, a Hazard Mitigation Analysis to prevent thermal-runaway cascades, early-acting fire suppression and gas detection, stored-energy caps for occupied buildings, and detailed safety documentation (UL). Battery Energy Storage Systems, or BESS, help stabilize electrical grids by providing steady power flow despite fluctuations from inconsistent generation of renewable energy sources and other disruptions. While BESS technology is designed to bolster grid reliability, lithium battery fires at some. NFPA 855 is the leading fire-safety standard for stationary energy-storage systems. This data sheet also describes location recommendations for portable. EPRI's research during Phase I consolidated the experience of 15 utility members, 15 non-utility experts, and 10 energy storage site evaluations to identify gaps in safe design and operations of today's ESS. Compromised lithium-ion batteries can produce significant amounts of flammable gases with potential risk of deflagration and fire. If a commercial or utility install, follow pre-plan and do not.
