FAQS about Fire protection in energy storage devices

Are battery energy storage systems safe?

WASHINGTON, D.C., March 28, 2025 — Today, the American Clean Power Association (ACP) released a comprehensive framework to ensure the safety of battery energy storage systems (BESS) in every community across the United States, informed by a new assessment of previous fire incidents at BESS facilities.

Does NFPA 855 permit alternative fire suppression systems?

NFPA 855 also permits the use of alternative fire suppression systems if they successfully pass large-scale fire testing in accordance with Underwriters Laboratories (UL) 9540A, “Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems,” or an equivalent standard.

What are the standards for ESS fire suppression systems?

Two commonly referenced standards for ESS fire suppression systems are FM Global Data Sheet (FM DS) 5-33 and NFPA 855. In the event of thermal runaway, it is essential to rapidly cool the affected module and its surroundings to prevent a chain reaction of battery fires.

Are energy storage facilities safe?

“The energy storage industry is committed to a proactive and tireless approach to safety and reliability. At its core, energy storage facilities are critical infrastructure designed to protect people from power outages,” said ACP VP of Energy Storage Noah Roberts.

What is an energy storage system (ESS) enclosure?

An energy storage system (ESS) enclosure typically comprises multiple racks, each containing several modules (Figure 1). These modules consist of numerous lithium-ion (Li-ion) cells, which function as rechargeable batteries designed to store and discharge electrical energy.

How did NFPA 855 impact the energy storage industry?

In Maryland and New York, the energy storage industry supported new regulations that enforced the latest NFPA 855 requirements. In California, the industry offered a suite of policy recommendations to address unique safety questions arising from the Moss Landing incident, including enforcing key provisions of NFPA 855.
