BESS Fires: Risks, Insurance and Safety Measures

As more businesses embrace renewable energy and integrate commercial battery energy storage systems (BESS), it’s vital to understand not just the benefits but also the potential risks. One of the primary concerns for many businesses considering a BESS installation is the risk of BESS fires. These fires, though relatively rare, can be severe, posing risks to property, safety, and financial stability.

In this blog post, we’ll discuss the fire risks associated with BESS, the role of insurance in protecting your investment, and the proactive steps battery providers like us take to mitigate these risks. We aim to give you confidence that, with the right precautions in place, the benefits of a commercial BESS far outweigh the risks.


Understanding the Risk of BESS Fires

The fire risk in BESS typically stems from the batteries themselves. Most commercial BESS units use lithium-iron phosphate (LFP) batteries, which are popular due to their high energy density, efficiency, and longevity. However, in rare cases, LFP batteries can become hazardous if they overheat, are physically damaged, or experience electrical faults.

The potential causes of BESS fires include:

  • Thermal Runaway: This occurs when a battery cell overheats, causing a chain reaction in adjacent cells, leading to a fire or explosion. Once thermal runaway starts, it’s challenging to contain, making it a critical risk factor in LFP batteries.


  • Overcharging or Over-discharging: Poorly managed charging cycles can lead to battery failures, increasing the chance of overheating and fire. This risk is more prevalent in systems without robust monitoring or control features.


  • Mechanical Damage: External forces, such as improper installation or physical impact (e.g., during maintenance or construction), can compromise the integrity of the battery, potentially triggering internal short circuits that lead to fires.


  • Environmental Conditions: Extreme temperatures, humidity, and improper ventilation in the installation site can exacerbate fire risks by affecting battery performance or cooling systems.

Despite these risks, it’s important to note that BESS fires are not common when systems are properly designed, installed, and maintained. As a provider, we focus heavily on ensuring our solutions are safe and reliable, with fire risk mitigation at the forefront of every project.


The Role of Insurance in Protecting Your Business

As a business owner considering or operating a BESS, insurance is one of the most critical aspects of managing the fire risk. Insurance can help safeguard your assets and provide financial protection if an incident does occur.

Types of Insurance Coverage

  1. Property Insurance: This type of insurance typically covers the physical damage to your business’s property, including your BESS installation, in the event of a fire. Make sure your policy explicitly includes energy storage systems as part of the coverage.


  2. Liability Insurance: If a BESS fire were to spread and cause damage to neighbouring properties or harm people, liability insurance would protect your business from legal claims and associated costs. This is especially important for businesses operating in densely populated or high-traffic areas.


  3. Business Interruption Insurance: A BESS fire could disrupt operations, potentially causing a halt in business activities. Business interruption insurance covers the lost income and extra expenses incurred during downtime due to a fire.

Working with Your Insurer

When setting up or upgrading your BESS, it’s essential to work closely with your insurer. Be transparent about the system’s size, location, and purpose to ensure you're properly covered. Some insurers may even require certain safety measures (which we’ll discuss next) before they approve a policy. As a BESS provider, we can assist in facilitating this process, ensuring all necessary documentation and safety protocols are in place to satisfy insurance requirements.


Steps to Mitigate the Risk of BESS Fires

While insurance can provide financial protection, the ultimate goal is to prevent fires from happening in the first place. At our company, we take a proactive approach to mitigating the risk of BESS fires through stringent design, installation, and maintenance practices. Here are key steps we implement to ensure fire safety in every commercial BESS project:

1. Advanced Battery Management Systems (BMS)

An essential tool in preventing BESS fires is a robust battery management system (BMS). The BMS continuously monitors battery health, temperature, and charge cycles to detect any anomalies before they lead to problems. It can automatically shut down the system if overheating or overcharging is detected, preventing thermal runaway and reducing the risk of fire.

As part of our installations, we ensure every BESS is equipped with state-of-the-art BMS technology, giving businesses peace of mind that their system is constantly being monitored for safety.

2. Thermal Management Systems

Effective cooling systems are crucial for preventing battery overheating, particularly in large-scale BESS installations. Proper thermal management ensures that batteries operate within safe temperature ranges, reducing the risk of thermal runaway.

There are several types of cooling systems that can be integrated into a BESS, such as air cooling, liquid cooling, or phase-change materials. We assess each project individually, ensuring the chosen cooling solution is appropriate for the system's size, location, and operating conditions.

3. Fire Detection and Suppression Systems

Installing fire detection and suppression systems is a fundamental safety measure. These systems can detect fires at an early stage and automatically activate to contain them before they spread. Suppression systems often use inert gases (such as argon or nitrogen) or aerosol-based systems to extinguish fires without causing damage to the electrical equipment.

As part of our fire mitigation strategy, we offer BESS solutions with built-in fire detection and suppression systems tailored to the specific needs of your facility.

4. Proper Siting and Installation Practices

The location of a BESS plays a significant role in mitigating fire risk. Ideally, battery systems should be installed in well-ventilated areas away from flammable materials and sensitive equipment. In cases where outdoor installations are necessary, protective enclosures or fireproof housing can further reduce the likelihood of fires spreading.

We work closely with business owners during the planning and design phase to ensure that the BESS is sited in a location that minimizes risk. Our installation teams follow rigorous safety standards to avoid potential hazards, such as accidental physical damage to the battery units during installation.

5. Routine Maintenance and Inspections

Regular maintenance is key to keeping any BESS safe and functional. Routine inspections help identify early signs of wear, overheating, or electrical issues that could increase the risk of fire. Battery modules, connections, cooling systems, and fire suppression units should be checked periodically for optimal performance.

At our company, we offer ongoing maintenance services as part of our BESS installations. This ensures that your system is not only operating efficiently but also remaining safe over its lifespan.
