Deploying Storage in an Urban Space

Media coverage of hazardous incidents involving lithium ion batteries in electric vehicles, renewable energy storage, and consumer electronics has caused growing public concern of the safety of battery energy storage systems (BESS) installed in populated areas, especially in cities. The occurrence and reporting of these events underscores the need for continuous safety advances through technical due diligence, evolving codes, and coordinated education to contextually understand, mitigate, and communicate BESS hazards and consequences.

Founded in Palo Alto in 1972, EPRI is an independent non-profit energy research, development, and deployment organization with a foundational mission to benefit society. EPRI delivers independent, objective thought leadership and industry expertise to help the energy sector identify issues, technology gaps, and broader needs that can be addressed through effective, collaborative research and development programs. EPRI is an industry leader in energy storage safety and has developed many tools and resources to move the industry towards a safe, reliable, affordable, and clean energy storage future.

This page highlights EPRI's ongoing energy storage safety research program and provides links resources that support and inform decisions around safety of energy storage systems deployed in urban spaces.

EPRI's Energy Storage Safety Research

Fire Prevention and Mitigation for Battery Energy Storage Systems (BESS)

With a foundational mission to benefit society, EPRI delivers independent, objective thought leadership and industry expertise to the energy sector. EPRI’s portfolio in energy storage includes a collaborative, multi-phase project to understand and close gaps in energy storage safety and subsequent impacts. Our work brings together industry experts to generate new knowledge, identify best practices, and develop a safety toolkit. The research is made publicly available to advance the industry.

Battery Storage Fire Safety Roadmap

Phase 1 of the project identified and prioritized 22 topics for future research. Topics include:

• Addressing the explosion hazard
• Response plan guidelines for existing and future systems
• Guidelines for selection and design of suppression systems
• Failure detection systems

BESS Failure Event Database

The database is a public resource documenting battery energy storage failures around the world. It catalogs over 100 incidents in utility and commercial/industrial installations, electric transportation, recycling, manufacturing, and warehousing...
