Understanding Hazard Mitigation Analyses (HMA) for BESS Projects

Battery Energy Storage Systems (BESS) are becoming a critical part of modern energy infrastructure, helping utilities, developers, and facility owners improve grid reliability and support renewable energy integration. As these systems continue to expand in size and complexity, fire and life safety considerations have become increasingly important.

One of the key tools used to evaluate and address potential hazards in battery energy storage projects is the Hazard Mitigation Analysis (HMA). Keystone Fire Consultants regularly supports BESS stakeholders through technical evaluations designed to improve safety, streamline permitting, and support code compliance.

What Is a Hazard Mitigation Analysis?

A Hazard Mitigation Analysis is a structured evaluation that identifies potential hazards associated with a battery energy storage system and examines strategies to reduce or manage those risks.

The purpose of an HMA is to provide project stakeholders, Authorities Having Jurisdiction (AHJs), and emergency responders with a clear understanding of the system’s hazards, protective features, and risk reduction measures.

For many BESS projects, an HMA serves as a critical component of the permitting and approval process.

Why Are HMAs Important for Battery Energy Storage Systems?

Lithium-ion battery technology offers significant operational benefits, but it also presents unique fire and safety considerations. Potential hazards may include:

  • Thermal runaway events
  • Fire propagation between battery modules
  • Gas generation and accumulation
  • Deflagration risks
  • Emergency response challenges
  • Equipment failures and operational anomalies

A well-developed HMA helps project teams understand these risks early in the design process and identify appropriate mitigation measures.

Key Components of an HMA

While every project is unique, a comprehensive Hazard Mitigation Analysis often includes:

System Overview

A detailed review of the battery technology, system configuration, operating conditions, and project layout.

Hazard Identification

Identification of potential failure scenarios, ignition sources, and operational hazards that could impact personnel, property, or system performance.

Risk Evaluation

Assessment of the likelihood and potential consequences of identified hazards.

Mitigation Strategies

Evaluation of protective measures such as:

  • Fire detection systems
  • Suppression systems
  • Ventilation strategies
  • Gas detection systems
  • Emergency shutdown procedures
  • Separation distances and system spacing

Emergency Planning Considerations

Review of emergency response procedures and coordination requirements with local first responders and AHJs.

Supporting the Permitting Process

Many jurisdictions require technical documentation demonstrating that battery energy storage projects have been evaluated for potential hazards and appropriate mitigation measures.

An HMA can help facilitate discussions between project developers, design teams, regulators, and emergency response agencies by providing a documented, data-driven evaluation of system safety considerations.

This often contributes to a more efficient permitting and review process while helping stakeholders make informed decisions regarding project design and operation.

Industry Standards and Code Considerations

Hazard Mitigation Analyses are typically developed with consideration for applicable codes, standards, and project-specific requirements. Depending on the project, these may include:

  • NFPA 855
  • International Fire Code (IFC)
  • Local jurisdictional requirements
  • Manufacturer documentation
  • Applicable fire protection engineering principles

The goal is to align safety strategies with recognized industry practices while addressing the specific characteristics of the proposed installation.
