How can EPRI help protect battery energy storage systems?

EPRI is currently working on a range of resources to help improve the safety of battery energy storage systems called the Project Lifecycle Safety Toolkit. It will include everything from data sets to white papers and guidebooks that provide practical steps to mitigate the risk of a battery fire and to optimize the response in case it occurs.

Where can I find information on energy storage safety?

For more information on energy storage safety, visit the Storage Safety Wiki Page. The BESS Failure Incident Database was initiated in 2021 as part of a wider suite of BESS safety research after the concentration of lithium ion BESS fires in South Korea and the Surprise, AZ, incident in the US.

What is an energy storage roadmap?

This roadmap provides necessary information to support owners, opera-tors, and developers of energy storage in proactively designing, building, operating, and maintaining these systems to minimize fire risk and ensure the safety of the public, operators, and environment.

How much does energy storage cost?

The long-duration energy storage technologies include Electrochemical, Mechanical, Thermal, and Chemical and typically have a duration of 10 hours or more. Estimated capital costs at $150–220/kWh, with the levelized cost of storage projected under $100/MWh for early projects. Potential to reduce to $50–60/MWh.

Where can I find information on energy storage failures?

For up-to-date public data on energy storage failures, see the EPRI BESS Failure Event Database.2 The Energy Storage Integration Coun-cil (ESIC) Energy Storage Reference Fire Hazard Mitigation Analysis (ESIC Reference HMA),3 illustrates the complexity of achieving safe storage systems.

Will energy storage grow in the future?

Projections about the future growth of energy storage are eye-opening. For context, consider that the U.S. Energy Information Administration (EIA) reported that 402 megawatts of small-scale battery storage and just over one gigawatt of large-scale battery storage were in operation in the United States at the end of 2019.
