Assessment of Potential Impacts of Fires at BESS Facilities

This report provides an analysis of historical BESS fire incidents and their causes, a review of the types of contaminants released, the extent of environmental impacts, and how advancements in safety regulations and technology have mitigated risks. Case studies illustrate the evolution of BESS safety and the limited environmental consequences of such fires.

Key findings include:

• Historical incidents: An analysis of BESS fire incidents in the United States reveals that the incidents involved early-generation systems lacking modern safety features. Improved safety measures in newer systems have significantly reduced risks.
• Environmental impact: Studies show that BESS fires have minimal long-term environmental impact. Airborne emissions are short-lived and localized, and soil and water contamination risks are minimal.
• Firefighting strategies: Modern firefighting tactics emphasize containment and cooling rather than active suppression, reducing potential environmental impacts.

Modern standards and designs have significantly improved fire safety and minimized environmental risks. Continuous advancements in technology and adherence to best practices ensure BESS remains a reliable and safe option.
