Safety requirements for energy storage equipment

Are battery energy storage systems safe?

This innovation is a major improvement for safer and more efficient energy storage solutions. Battery Energy Storage Systems are essential for the future of energy, but safety must always come first. Each of the safety standards relevant to BESS plays a unique role in ensuring the systems’ safety, reliability, and performance.

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.

What are the UL 9540 standards for energy storage systems?

The following are the most widely recognized benchmarks for system-level safety. UL 9540 is the comprehensive safety standard for energy storage systems (ESS), focusing on the interaction of system components. It evaluates the overall performance, safety features, and design of BESS, ensuring they operate effectively without compromising safety.

What are energy storage safety gaps?

Energy storage safety gaps identified in 2014 and 2023. Several gap areas were identified for validated safety and reliability, with an emphasis on Li-ion system design and operation but a recognition that significant research is needed to identify the risks of emerging technologies.
