fire protection for BESS systems

Fire Protection for Battery Energy Storage Systems (BESS)

Battery Energy Storage Systems (BESS) are at the forefront of modern energy infrastructure, supporting everything from renewable energy grids to commercial energy management systems. But with this innovation comes new fire safety challenges. At Spectrum Fire Protection, we have in-depth knowledge of the fire risks associated with lithium-ion battery installations and a proven track record in protecting BESS facilities across the UK.

The Fire Risks of BESS Environments

The Fire Risks of BESS Environments

Battery storage systems, particularly those using lithium-ion technology, pose unique hazards — including the potential for thermal runaway, chemical fires, and gas emissions. These types of incidents can be extremely difficult to extinguish with conventional methods and may rapidly escalate if not properly detected and contained.

As BESS installations become more widespread across commercial, industrial, and energy sectors, ensuring robust and compliant fire safety systems is essential. Spectrum Fire Protection offers sector-specific solutions designed to detect, suppress, and mitigate the risks posed by high-density energy storage.

Our Expertise in BESS Fire Protection

With over 35 years of fire protection experience, Spectrum combines deep industry knowledge with cutting-edge system design. We understand the environmental and technical requirements of BESS installations — whether housed in dedicated structures, modified shipping containers, or integrated within commercial facilities.

Our services include:

Early Warning Detection Systems
Using aspirating smoke detectors and heat detection sensors capable of identifying early signs of thermal runaway or off-gassing within battery modules.
Specialist Gas Suppression Systems
Inert and clean agent gas systems such as Novec™ 1230 or FM-200™ designed for use in enclosed battery units. These systems suppress fire while avoiding damage to sensitive electrical equipment.
Fire-Rated Enclosures and Compartmentation
Engineering solutions to contain fire within a defined space, preventing escalation to adjacent areas and supporting fire-fighting response.
Continuous System Monitoring
Integration with BMS (Building Management Systems) or standalone monitoring panels for real-time status updates and remote alerts.
Emergency Venting Systems
Support for the safe release of pressure and hazardous gases in the event of internal battery failure or fire.
Maintenance and Compliance Services
Scheduled servicing and compliance checks to meet BS EN standards, UK fire safety regulations, and insurance provider requirements.

Compliance and Best Practice

BESS fire protection requires more than just off-the-shelf solutions. Systems must be tailored to the specific battery chemistry, enclosure type, and operational environment. Spectrum Fire Protection works to ensure full compliance with:

The Regulatory Reform (Fire Safety) Order 2005
BS 7671 and BS EN 61508 for electrical safety and system integrity
Fire and gas detection system guidance from NFPA and FIA (Fire Industry Association)
Guidance from DNOs (Distribution Network Operators) and battery manufacturers

We also liaise with fire authorities and insurers to ensure that your fire strategy satisfies all stakeholder requirements.

Supporting Green Infrastructure and Renewable Energy

Spectrum Fire Protection is proud to support the transition to cleaner energy by making BESS installations safer and more resilient. We work with clients across renewable energy sectors — including wind, solar, and EV infrastructure — ensuring that fire risks are managed from the ground up.

Whether part of a utility-scale project, a commercial microgrid, or a private energy storage facility, our team will help ensure your BESS installation remains protected and compliant at all times.
