6 FAQs about Energy storage discipline code

Are energy storage systems compliant?

Energy storage systems continue to be a rapidly evolving industry. Thus, the key to safe and up-to-date compliance requirements involves the adoption and application of codes and standards in addition to the development or writing of codes and standards.

What if energy storage system and component standards are not identified?

Energy Storage System and Component Standards 2. If relevant testing standards are not identified, it is possible they are under development by an SDO or by a third-party testing entity that plans to use them to conduct tests until a formal standard has been developed and approved by an SDO.

How are energy storage systems regulated?

In some contexts, for energy storage systems, compliance regulations take the form of a state adopting a code, which then references and requires testing and listing or adherence to a standard. Some cities, counties, and special administrative districts (e.g., school or sewer districts) also adopt locally amended codes for their environments.

What is a 'contingency' for removing an energy storage system?

Section 1207.2.1 of the IFC requires the plan to include 'contingencies for removing an intact operational energy storage system from service, and for re-moving an energy storage system from service that has been damaged by a fire or other event' (emphasis added).

Do energy storage systems need a CSR?

Until existing model codes and standards are updated or new ones developed and then adopted, one seeking to deploy energy storage technologies or needing to verify an installation's safety may be challenged in applying current CSRs to an energy storage system (ESS).

What is the UL 9540 standard for energy storage systems?

For ESS, the standard is UL 9540, Standard for Energy Storage Systems and Equipment. UL 9540 covers the complete ESS, including batery system, power conversion system (PCS), and energy storage man-agement system (ESMS). Each of these components must be qualified to its own standard:
