ESS Safety Working Group | August Newsletter


“Foster confidence in the safety and reliability of energy storage systems.”

In order to encourage open, transparent, and ongoing communication and collaboration among all stakeholders and their associations and organizations, we have started a bi-monthly newsletter to facilitate up-to-date knowledge of energy storage systems (ESS) safety news, events, and working group activities. 

If you have relevant content to include in the next issue, email your suggested content to by October 15.  

Recent News

R&D Data Repository Website Now Available

A new R&D Data Repository has been added to the energy storage safety working group website. This site holds a collection of public data to support a broad-based research effort toward the advancement of energy storage system safety. This repository is intended to host public access data supplied by institutions and testing laboratories working on energy storage safety research. If you have a data set that you would like to host in the repository, please e-mail us at

Energy Storage Systems -  Overview of the Technology, Safety Related Issues and Codes/Standards

PNNL and Sandia have prepared a Power Point that provides an overview of energy storage technologies and safety related issues. The presentation is intended to provide a foundation of energy storage safety knowledge that is applicable and useful to a broad range of stakeholders.

Noteworthy Publications

Safety Focused Modeling of Lithium-ion Batteries: A Review

Researchers at IFP Energies Nouvelles, INERIS, and Sorbonne Universités published a review of modeling techniques used to analyze the safety of lithium-ion batteries that is gaining interest, attention, and citations. The paper presents an in-depth outlook of modeling approaches for investigating Li-ion battery safety with a special focus on thermal runaway and the influence of aging.

Energy Storage System Safety: Comparing Vanadium Redox Flow and Lithium-Ion Based Systems

Energy Response Solutions, a consulting company that provides training materials and safety related resources to the fire service community, released a white paper comparing the different hazards, controls, and code requirements for lithium-ion an vanadium redox flow battery systems.

Codes and Standards

Focus on Codes and Standards - July and August Reports

The Codes and Standards Reports for May, June, July  and August 2017 support the Safety Roadmap by providing information on current and upcoming efforts being conducted by U.S. standards developing organizations and other entities that are focused on ESS safety. The model codes, standards, and other documents (guidelines, recommended practices, etc.) covered in each report are classified in relation to their scope relative to ESS from the ‘macro to the micro’ and include overarching codes and standards as well as codes and standards for installation, complete ESS, and components. The reports are issued monthly to ensure the information provided is timely, as development of the covered documents is very dynamic.

Upcoming Events and Important Dates

National Electrical Code (NEC)

Proposed changes to the next version of the NEC are due to the National Fire Protection Association September 7th. The last version included Article 706 on energy storage systems. Make sure to submit your changes by the deadline. A list of standards and important dates can be found in the Status of Codes and Standards section of the ESS Working Group website.

NFPA 855

An initial draft of NFPA 855, Standard for the Installation of Stationary Energy Storage Systems, is now available for first public input with a due date of October 4, 2017. Comments received from the first public input will be discussed by the NFPA 855 Committee at their meeting in Dallas, TX on October 23-25, 2017.
