UL has created a certification service for Energy Storage Equipment Subassemblies (ESES) to evaluate for compliance to UL 9540, the Standard for ESES. This allows manufacturers of large energy storage assets to procure certified (listed) components from the battery supplier and the power conditioning equipment supplier to create the Energy Storage System (ESS).
UL certified three ESES for NHOA Energy (formerly Engie EPS), NHOA Group’s Global Business Line dedicated to stationary energy storage that designs and delivers turn-key storage systems, helping independent power producers to achieve their renewable targets.
The ESES Certification program makes it easier for Direct Current (DC) storage system manufacturers, code authorities and owners of ESS assets to: Demonstrate DC storage systems meet UL 9540; Have flexibility when pursuing UL’s Battery and ESS Testing and Certification services; Find suppliers within UL Product iQ; and Navigate a rapidly changing code and regulatory compliance environment.
Commenting on the development, Maurice H. Johnson, a product manager for batteries and energy storage systems in UL’s Energy and Industrial Automation group, said, “Through the new ESES Certification, a DC storage system manufacturer has an easier and faster path toward Certification to UL 9540. This is another example of how our cost-effective and time-sensitive certification strategies deliver the utmost flexibility and superior certification methods, accelerating time to market. UL is first to offer this type of Certification, and we are proud that we can pair it with our world-class fire propagation testing.”
