Battery Energy Storage Systems (BESS) are expanding rapidly in the context of the global energy transition. However, this growth is accompanied by new risks, particularly fires linked to lithium-ion batteries and their thermal runaway. According to the Electric Power Research Institute (EPRI), more than 85 BESS incidents have been recorded worldwide since 2011. Meanwhile, a report from Energy Storage shows that around 26% of inspected storage systems have issues related to fire detection and suppression. These numbers highlight the critical importance of implementing a robust automatic fire detection and suppression strategy from the design stage of any BESS installation.


Key challenges of automatic detection and suppression : why early detection is essential

The study “Safety and Reliability Analysis of Reconfigurable Battery Energy Storage System” (MDPI, 2024) reports that 57% of BESS failures occur within the first two years of operation, indicating that the initial operating phase is particularly vulnerable. According to Battery Power, only ~11% of BESS fires/explosions are directly caused by a defective battery module, while ~65% originate from “operational and integration issues”, such as improper installation or inadequate cooling.

In other words: efficient system detection and management can make the difference between a simple warning and a major disaster.


Why automatic suppression must be designed specifically for BESS

Traditional fire suppression systems (water-based or foam-only systems) have major limitations when applied to BESS installations due to factors such as flammable gas buildup, thermal propagation risks, sensitive electrical equipment, and confined spaces. When combined with a condensed aerosol solution such as Stat-X, they become both more effective and faster to activate.

Selected solutions must therefore:

  • act before rapid fire propagation (via automatic detection)
  • limit collateral damage to equipment and facilities
  • operate effectively in confined environments with interconnected battery racks
  • remain modular and adaptable to each site’s risks and configuration.

Our distinctive solution : Stat-X Condensed Aerosol Fire Suppression


Stat-X is specifically designed for BESS risks. Here’s why:

  • BESS installations are usually housed in closed rooms or containers; the Stat-X aerosol system is optimized for these confined volumes.
  • Aerosol technology reduces the risk of electrical damage, leaves no corrosive residue, and enables faster system restart.
  • Integrated detection + suppression: by combining suitable detectors (smoke, thermal radiation, gas) with automatic suppression, we deliver a turnkey fire safety solution for BESS.
  • Compliance and technical excellence: Stat-X is certified by DNV and other major industry bodies, ensuring high reliability and performance.
  • Lower fire risk also improves insurance coverage and operational continuity.
