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.

Should battery fire suppression systems be mandatory?

The incidence of battery fires is increasing. Today’s larger battery systems use tens of thousands of cells, so fires are inevitable. Battery fires emit toxic fumes and pose a risk to the community. Fire suppression systems should be mandatory for all lithium-ion battery systems.

What are the safety requirements for energy storage projects

UL 9540 defines the safety requirements for energy storage systems and equipment. NFPA 855 outlines installation rules that minimize fire risk. Together, they form the foundation of residential storage safety. As capacity grows beyond 10kWh, following these standards becomes even more essential. [pdf]

FAQS about What are the safety requirements for energy storage projects

Are energy storage facilities safe?

These established safety standards, like NFPA 855 and UL 9540, ensure that all aspects of an energy storage project are designed, built, and operated with safety as the highest priority. Energy storage facilities are monitored 24/7 by trained personnel prepared to maintain safety and respond to emergency events.

What's new in energy storage safety?

Since the publication of the first Energy Storage Safety Strategic Plan in 2014, there have been introductions of new technologies, new use cases, and new codes, standards, regulations, and testing methods. Additionally, failures in deployed energy storage systems (ESS) have led to new emergency response best practices.

How do energy storage facilities maintain safety?

Facilities use multiple strategies to maintain safety, including using established safety equipment and techniques to ensure that operation of the battery systems are conducted safely. Energy storage technologies are a critical resource for America’s power grid, boosting reliability and lowering costs for families and businesses.

How does the energy storage industry promote safety?

The energy storage industry is continually promoting safety, encouraging localities across the country to adopt robust safety standards, collaborating with first-responder groups and fire service organizations, and sharing lessons learned and safety resources.

What are the three pillars of energy storage safety?

A framework is provided for evaluating issues in emerging electrochemical energy storage technologies. The report concludes with the identification of priorities for advancement of the three pillars of energy storage safety: 1) science-based safety validation, 2) incident preparedness and response, 3) codes and standards.

Why do energy storage projects need a fire service?

The energy storage industry is committed to partnering with the fire service to promote safe and reliable operation. From the blueprint of a project site to the specially engineered battery containers, energy storage projects are inherently designed to perform safely and reliably on the grid.

Small energy storage cabinet installation environment requirements standard

You have four options for siting ESS in a residential setting: an enclosed utility closet, basement, storage or utility space within a dwelling unit with finished or noncombustible walls. . SEAC’s Storage Fire Detection working group strives to clarify the fire detection requirements in the International Codes (I-Codes). The 2021 IRC calls for the installation of heat detectors that are interconnected to smoke alarms. The problem is detectors. . The Storage Fire Detection working group develops recommendations for how AHJs and installers can handle ESS in residential settings in. . The IFC requires bollards or curb stops for ESS that are subject to vehicular impact damage. See the image below for garage areas that are not subject to damage and don’t require bollards. [pdf]

FAQS about Small energy storage cabinet installation environment requirements standard

Do energy storage systems need a CSR?

Until existing model codes and standards are updated or new ones developed and then adopted, one seeking to deploy energy storage technologies or needing to verify an installation’s safety may be challenged in applying current CSRs to an energy storage system (ESS).

What if energy storage system and component standards are not identified?

Energy Storage System and Component Standards 2. If relevant testing standards are not identified, it is possible they are under development by an SDO or by a third-party testing entity that plans to use them to conduct tests until a formal standard has been developed and approved by an SDO.

Are battery energy storage systems the future of grid stability?

Battery Energy Storage Systems represent the future of grid stability and energy efficiency. However, their successful implementation depends on the careful planning of key site requirements, such as regulatory compliance, fire safety, environmental impact, and system integration.

What is the new NEC Article 706 energy storage system?

The 2017 NEC is likely to replace references to ESS installation in Article 480 and has proposed a new Article 706 Energy Storage Systems that consider the application of electrochemical energy storage along with other types of energy storage that are referenced in other Articles within the code (e.g., PV, Wind, etc.)

Do electric energy storage systems need to be tested?

It is recognized that electric energy storage equipment or systems can be a single device providing all required functions or an assembly of components, each having limited functions. Components having limited functions shall be tested for those functions in accordance with this standard.

Why do energy storage systems need security measures?

Given the scale of energy storage systems and the value of the equipment involved, security is another top concern for BESS installations. These systems are often located in remote or semi-isolated areas, making them vulnerable to theft, vandalism, or sabotage. Therefore, implementing strong physical security measures is essential.
