Recommendation of energy storage fire extinguishing system

storage fire safety issues in order to help avoid safety incidents and loss of property, which have become major challenges to the widespread energy storage deployment. The research topics identified in this roadmap should be addressed to increase battery energy storage system (BESS) safety and reliability.

Summary. The following document summarizes safety and siting recommendations for large battery energy storage systems (BESS), defined as 600 kWh and higher, as provided by the New York State Energy Research and Development Authority (NYSERDA), the Energy Storage Association (ESA), and DNV GL, a consulting company hired by Arizona Public Service .

SAFETY REVIEWS OF SITES IN OPERATION AND DESIGN. EPRI conducted evaluations of energy storage sites (ESS) across multiple regions and in multiple use cases (see Table 1) to capture the current state of fire prevention and mitigation. Of those sites, six are operational, two are under construction, and two are in design.

6 FAQs about [Recommendation of energy storage fire extinguishing system]

What is battery energy storage fire prevention & mitigation?

In 2019, EPRI began the Battery Energy Storage Fire Prevention and Mitigation – Phase I research project, convened a group of experts, and conducted a series of energy storage site surveys and industry workshops to identify critical research and development (R&D) needs regarding battery safety.

What are the energy storage operational safety guidelines?

In addition to NYSERDA’s BESS Guidebook, ESA issued the U.S. Energy Storage Operational Safety Guidelines in December 2019 to provide the BESS industry with a guide to current codes and standards applicable to BESS and provide additional guidelines to plan for and mitigate potential operational hazards.

Is fire suppression equipment included in an ESS?

suppression equipment may or may not be provided as an integral part of an ESS, or it may be optional. Depending on the case, the ESS shall comply with all applicable performance requirements in the standard with and/or without the fire detection and fire suppression equipment in place and operational.

What should first responders know about energy storage systems?

This document provides guidance to first responders for incidents involving energy storage systems (ESS). The guidance is specific to ESS with lithium-ion (Li-ion) batteries, but some elements may apply to other technologies also. Hazards addressed include fire, explosion, arc flash, shock, and toxic chemicals.

How many large-scale battery energy storage sites have been affected by fires?

4. Planning for Failure Requires Choices: Varying Levels of Over the past four years, at least 30 large-scale battery energy storage sites (BESS) globally experienced failures that resulted in destructive fires.1 In total, more than 200 MWh were involved in the fires.

Is energy storage safety a quanti-tative process?

Testing for energy storage performance or failure modes is a quanti-tative, objective process, but safety combines objective probabilities with subjective assessment of the acceptability of ever-present haz-ards.
