Updated Safety Guidelines Released for Large-Scale Battery Storage Systems

A national energy storage association has issued a major update to safety guidelines for large-scale battery storage, reflecting current lithium-ion battery safety standards and best practices across the entire lifecycle of grid-scale energy storage systems.

Comprehensive Update for Battery Storage Safety

A national energy storage organization has released a fully revised safety guideline for large lithium-ion battery systems. This update replaces a previous fire protection document and now incorporates safety requirements covering every stage of large-scale battery storage systems—from planning and transport to operation, IT security, second-life applications, and eventual decommissioning.

Growing Market Demands Higher Safety Standards

As energy storage projects surpass 1 GWh in scale, the sector requires advanced lithium-ion battery safety standards and consistent installation guidelines. Existing regulatory frameworks have helped prevent major incidents, but the rapid expansion of energy storage systems calls for regularly refreshed recommendations aligned with modern industry conditions.

Built on Technical Standards and Real-World Experience

The updated guideline draws on current engineering standards, established regulatory practices, and extensive field experience. It covers a broad set of requirements, including:

• Structural and system-level fire protection
• Risk assessments and operational safety concepts
• IT security, data processing, and battery analytics
• Regulatory impacts of recent European battery legislation
• Permitting procedures and insurance considerations
• Requirements for large ground-mounted battery storage installations

Support for Operators, Planners, and Authorities

The publication provides practical, application-oriented guidance for operators, developers, insurers, and regulatory authorities. National fire services are expected to adopt the guideline and publish their interpretation through official channels.

Collaborative Development Across Sectors

Experts from industry, science, public agencies, firefighting services, and the insurance sector contributed to the creation of the guideline. This collaborative effort highlights a shared commitment to expanding battery storage infrastructure safely and reliably, reinforcing the foundation for a resilient, future-oriented energy system.
