New energy storage field standards
UL and IEC have updated safety standards, and NFPA introduced comprehensive requirements for energy storage, fire safety and emergency planning in 2023. The standard also cross-references NFPA 855 installation rules, so passing UL 9540 streamlines local approvals. The storage of industrial quantities of thermal energy is in a nascent stage and primarily consists of sensible heat storage in nitrate salt eutectics and mixtures. Since the first edition in 2020, each cycle has refined how the standard addresses. . This fact sheet provides an overview of the key innovations that make today's battery storage projects less susceptible to fire and that greatly reduce the extent of fires if they do occur. Industry innovations have significantly improved BESS technology and safety standards. [PDF Version]
New energy storage standards are implemented
With the 2026 edition of NFPA 855 expected to be finalized and published in 2025, the energy storage industry is already incorporating key enhanced requirements and is ready to work with states and local governments to implement the latest version of the standard., March 28, 2025 — Today, the American Clean Power Association (ACP) released a comprehensive framework to ensure the safety of battery energy storage systems (BESS) in every community across the United States, informed by a new assessment of previous fire incidents at BESS. . In response to a request from CESA, the National Fire Protection Association (NFPA) published its first BESS standard, NFPA 855, in 2020. The NFPA 855 standard, which is largely adopted in the California Fire Code, is updated every three years. In light of the recent fire at the Moss Landings Energy Storage facility, which led. . If your team installs or works near battery energy storage systems (BESS), a new fire safety standard is going to affect how those systems get designed, approved, and built. [PDF Version]
New air compression energy storage
The world's largest compressed-air storage plant has been switched on at a salt cave in China, according to a statement from Harbin Electric Group, significantly bolstering long-duration energy storage capacity in the region. 4 GWh adiabatic compressed air energy storage (CAES) plant now operational in in Jiangsu province. [1] The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany. . Compressed Air Energy Storage (CAES) has emerged as one of the most promising large-scale energy storage technologies for balancing electricity supply and demand in modern power grids. [PDF Version]

What are the requirements for a battery energy storage system?
The requirements of this ordinance shall apply to all battery energy storage systems with a rated nameplate capacity of equal to or greater than 1,000 kilowatts (1 megawatt).
What is an energy storage system (ESS)?
Covers an energy storage system (ESS) that is intended to receive and store energy in some form so that the ESS can provide electrical energy to loads or to the local/area electric power system (EPS) when needed. Electrochemical, chemical, mechanical, and thermal ESS are covered by this Standard.
What are the NFPA requirements for energy storage systems?
5 NFPA 855 and NFPA 70 includes requirements for security and barriers to enhance the safety and protecon of energy storage systems. These requirements are aimed at prevenng unauthorized access, as well as containing and securing the site. Security barriers may involve measures such as fencing, gates, locks, access controls, and
Does this ordinance apply to battery energy storage systems?
