This paper will focus on the specific codes and standards for stationary energy storage systems (ESS). This requirement comes at a timely moment in the ongoing evolution of the U.S. electric grid.
View DetailsSince 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.
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.
U.S. fire and electrical codes require that energy storage systems be listed, meaning the product must be tested by a Nationally Recognized Testing Laboratory (a private-sector organization recognized by the Occupational Safety and Health Administration) and certified to meet consensus-based test standards.
For ESS, the standard is UL 9540, Standard for Energy Storage Systems and Equipment. UL 9540 covers the complete ESS, including battery system, power conversion system (PCS), and energy storage man-agement system (ESMS). Each of these components must be qualified to its own standard:
