How can energy storage products be integrated?

Integration of energy storage products begins at the cell level and manufacturers have adopted different approaches toward modular design of internal systems, all with the goal of improving manufacturing efficiencies, reducing maintenance time and improving operational reliability.

Do energy storage systems need to be listed?

It is critical for projects moving forward that execution teams understand that the International Fire Code (IFC), NFPA 855 and NFPA 70 (the National Electric Code) require energy storage systems to be listed, and that UL 9540 is the listing standard applicable.

Can energy storage be a single high-level resource?

This report summarizes over a decade of experience with energy storage deployment and operation into a single high-level resource to aid project team members, including technical staff, in determining leading practices for procuring and deploying BESSs.

What is a battery energy storage system?

Battery energy storage systems (BESS) stabilize the electrical grid, ensuring a steady flow of power to homes and businesses regardless of fluctuations from varied energy sources or other disruptions. However, fires at some BESS installations have caused concern in communities considering BESS as a method to support their grids.

What happened at Gateway energy storage facility?

On May 15, 2024, Gateway Energy Storage Facility in San Diego, California, experienced a BESS fire with continued flare-ups for seven days following the fire. The facility held about 15,000 nickel manganese cobalt lithium-ion batteries.

How is NFPA 855 reshaping the energy storage industry?

Updates to key energy storage system codes and safety standards, particularly NFPA 855, UL 9540, UL 9540A and the expanding adoption of IEEE 2800, is reshaping the landscape for system developers, integrators and asset owners.
