Mitigation Analysis for Energy Storage System Deployment Efficiency, Safety, and Compliance

Session: Rapid-Fire Introductions by Poster PresentersDate: Wednesday, October 16, 2019 / 8:50AM - 9:20AM PDTTags: Poster / Deployment and Field Experience

This presentation will provide an overview of risk assessment work undertaken by EPRI with Warner Energy Storage Solutions for the purpose of developing hazard mitigation and risk analysis models which may be used to evaluate energy storage systems. These analyses allow evaluation of specific threats such that the barriers against a threat or consequence may be identified and weighed. This technique allows for the direct comparison of systems and failure pathways and may lend itself to the quantification or valuation of safety within a system or the direct evaluation of similar systems against each other when evaluating proposals and deployments.

The featured methodology, the bowtie analysis, also allows for easy to follow, qualitative analysis of a system and has been received and better understood by lay stakeholders. This shall prove helpful moving forward with coming fire codes requiring hazard analysis of these systems. As such, this presentation shall also cover the use of these analysis for fire code compliance as well as for internal safety evaluation. Finally, this presentation will dive into the more critical failure modes and components of the systems and discuss how one may go about weighing these issues and conveying this decision making to fire and code officials.
