Safety Working Group

The PGS-37 committee, in which ESNL participated, has developed a safety framework for energy carriers containing lithium ion. To ensure that the safety framework meets the needs of the storage industry, ESNL and its members established a Safety Working Group. This working group has advised the PGS-37 committee over the past period. The purpose of this framework is to establish a safety standard for both existing and new battery systems with capacities greater than 20 kWh. The published measures apply to systems with a maximum capacity of 400 MWh. For larger systems, customization is required, requiring a risk analysis. The safety framework distinguishes between energy storage systems based on enclosure (Typical 1 - 3) and based on placement (Typical 4 - 6). Most measures apply only to certain types of systems.
