SAFETY TEMPERATURE STANDARDS FOR ENERGY STORAGE BATTERY
New Energy Storage Power Supply Safety Standards
In this article, we briefly discuss each of the 20 proposals adopted in the third edition of UL 9540. UL 9540 is a safety standard for the construction, manufacturing, performance testing and marking of grid-tied ESS. This includes electrochemical, chemical, mechanical, and thermal storage systems.

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.
What is an energy storage system (ESS)?
Covers an energy storage system (ESS) that is intended to receive and store energy in some form so that the ESS can provide electrical energy to loads or to the local/area electric power system (EPS) when needed. Electrochemical, chemical, mechanical, and thermal ESS are covered by this Standard.
What does ul 9540 mean for energy storage systems & equipment?
The third edition of the UL 9540 Standard for Safety for Energy Storage Systems and Equipment, published in April 2023, introduces replacements, revisions and additions to the requirements for system deployment.
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.
Do I need a sprinkler system for a battery ESS?
A: Testing has shown that water is the most efective agent for cooling for a battery ESS. For this reason, a sprinkler system designed in accordance with NFPA 13, Standard for the Installation of Sprinkler Systems, is required by NFPA 855, Standard for the Installation of Energy Storage Systems.
Why do we need energy storage systems?
Growing concerns about the use of fossil fuels and greater demand for a cleaner, more eficient, and more resilient energy grid has led to the use of energy storage systems (ESS), and that use has increased substantially over the past decade.
What are the Swedish energy storage battery standards
As of today, there are no national regulation, rules, requirements, advice, or standards available in Sweden on how to design a BESS in terms of fire safety. The lack of national advice leads to an uncertainty on how BESS should be designed and if and where they can be installed. [pdf]FAQS about What are the Swedish energy storage battery standards
Can battery energy storage systems be installed in Sweden?
There are currently no national rules, advice or standards for how fire protection should be dimensioned or where battery energy storage systems can be installed in Sweden. This creates an uncertainty for those who want to install battery energy storage systems. The aim of this project is to produce national guidelines regarding fire safety of BESS
What role does battery storage play in Sweden's energy infrastructure?
This increase underscores the growing role of battery storage systems in stabilising and supporting Sweden’s energy infrastructure. Swedish Solar Energy launched version 1.1 of its fire protection guideline for stationary battery storage systems on October 29, 2024.
Are batteries the key to achieving Sweden's climate goals?
Batteries are a crucial piece of the puzzle if we are to achieve Sweden’s climate goals with net-zero emissions by 2045. Batteries enable the phasing out of fossil fuels and increase flexibility in the electricity system through energy storage. The Swedish battery industry is at the forefront.
Why should you invest in batteries in Sweden?
Batteries enable the phasing out of fossil fuels and increase flexibility in the electricity system through energy storage. The Swedish battery industry is at the forefront. Sweden also has related strengths and opportunities in areas such as vehicles and electrical systems, as well as a strong mining cluster.
What is the new fire protection guideline for stationary battery storage systems?
Swedish Solar Energy launched version 1.1 of its fire protection guideline for stationary battery storage systems on October 29, 2024. Developed with industry input, the guideline is aimed at enhancing the safety of lithium battery installations across residential and commercial settings.
How many batteries have been pre-qualified for the Swedish power grid?
The number of batteries pre-qualified to deliver support services to the Swedish power grid rose substantially from 40 MW to 80 MW in 2023. By early October 2024, more than 530 MW of battery capacity had been pre-qualified, with several additional projects awaiting approval.
