BESS Fire Safety and Installation Requirements China uses GB 44240-2024 and GB/T 36276-2023 for cell and system safety, GB/T 36558-2023 for grid-connected BESS requirements, and project-specific fire-safety review processes administered by local fire authorities. These Chinese fire-safety review processes do not transfer to Sri Lanka fire authority requirements.GB 44240-2024
GB/T 36276-2023
GB/T 36558-2023		 Sri Lanka does not yet have a dedicated national BESS fire-safety standard equivalent to IEC 62933-5-2 or NFPA 855. However, BESS installations in Sri Lanka are subject to general fire safety and building regulations administered by the local fire authority (Sri Lanka Fire Brigade or municipal fire offices). Project owners, insurers, and CEB may require fire-safety evidence including thermal-runaway mitigation measures, gas detection or ventilation design, emergency shutdown procedures, and installation segregation documentation. PUCSL-regulated projects may be subject to additional safety review.Sri Lanka Fire Services Act and local fire authority requirements
IEC 62619: Thermal abuse and safety tests at cell/module level
IEC 62933-5-2: Safety requirements for grid-integrated energy storage systems (reference standard for project owners)
Local building and fire regulations applicable to BESS installation sites		 Chinese product-level safety certificates do not close the Sri Lanka fire-safety gap for BESS installations. Exporters should prepare thermal-runaway propagation test evidence, gas detection or ventilation design documentation, emergency shutdown logic description, installation segregation drawings, and English-language emergency response procedures for review by the Sri Lanka local fire authority, project owner, and insurer before commissioning.[INFORMATIONAL] Chinese GB battery safety certification alone is not sufficient for Sri Lanka BESS project installation approval. Prepare a fire-safety documentation package including thermal-runaway evidence, gas detection design, emergency procedures, and installation drawings for local fire authority, project owner, and insurer review.

PUCSL / CEB Grid-Connection and Storage-Integration Requirements China uses GB/T 36558-2023 for electrochemical energy storage system grid-connection requirements and GB/T 34120-2023 for PCS technical requirements. State Grid and Southern Grid enterprise rules govern project-specific interconnection. These Chinese standards target the Chinese grid with different protection settings and utility interconnection requirements from CEB's Sri Lanka specifications.GB/T 36558-2023
GB/T 34120-2023
State Grid / China Southern Power Grid project interconnection rules		 BESS projects connecting to the Sri Lanka grid must satisfy PUCSL regulatory requirements and CEB interconnection review under the Sri Lanka Electricity Act. CEB's technical requirements for grid-connected storage cover the power conversion system (PCS) anti-islanding, power quality, protection relay settings, metering, communication, and commissioning for the 50 Hz Sri Lanka grid. Requirements vary by voltage level, capacity, connection point (distribution or transmission), and project type. PUCSL issues storage-related guidelines and CEB handles project-specific technical review.Sri Lanka Electricity Act No. 36 of 2024 (as amended by Act No. 14 of 2025)
PUCSL grid-connection and distributed-generation regulations
CEB interconnection and technical requirements for grid-connected storage
IEC 62933-5-2: Safety requirements for grid-integrated energy storage systems		 Chinese PCS and BESS grid-connection certificates and test reports must be re-evaluated against CEB grid-code parameters for the 50 Hz Sri Lanka grid. Exporters should prepare CEB-compatible PCS technical specifications, protection relay settings, ride-through and anti-islanding data, metering design, single-line diagrams, and commissioning procedures for CEB project review. Engage PUCSL for regulatory clarification on storage-specific licensing requirements.[INFORMATIONAL] Chinese GB/T grid-connection evidence does not satisfy CEB technical review for Sri Lanka grid-connected BESS.

IEC 62619 Cell and Module Safety — SLSI Baseline for BESS China uses GB 44240-2024 as the compulsory safety requirement for lithium-ion cells and batteries for electric energy storage, and GB/T 36276-2023 as the recommended technical standard for electric energy storage lithium-ion batteries. IEC 62619 and Chinese GB 44240-2024 have significant technical overlap for cell-level safety, but they are different standards with different testing and certification bodies. Chinese GB certification does not replace IEC 62619 test evidence required by SLSI.GB 44240-2024
GB/T 36276-2023		 Sri Lanka Standards Institution (SLSI) adopts IEC standards as the technical baseline for electrical and energy-storage equipment. For BESS lithium-ion cells and battery modules, IEC 62619 (Safety requirements for secondary lithium cells and batteries for use in industrial applications) is the primary safety standard. SLSI may require product registration or conformity evidence before importation and sale of BESS components. Importers should confirm the current SLSI type-approval or registration requirement for battery energy storage with SLSI before shipment.IEC 62619: Secondary lithium cells and batteries for use in industrial applications — Safety requirements
SLSI type-approval or registration requirements for energy storage equipment		 Chinese GB 44240-2024 or GB/T 36276-2023 test reports do not substitute for IEC 62619 test evidence. Exporters should obtain IEC 62619 test reports from an internationally accredited laboratory, confirm SLSI registration or type-approval requirements for BESS before shipment, and prepare English-language technical documentation for SLSI and project-owner review.[INFORMATIONAL] Chinese GB 44240-2024 or GB/T 36276-2023 reports do not satisfy SLSI IEC 62619 requirements. Obtain IEC 62619 test evidence from an accredited laboratory and confirm SLSI registration requirements before shipping BESS to Sri Lanka.

IEC 62933 System-Level BESS Requirements China uses GB/T 36276-2023 for electric energy storage lithium-ion battery systems and GB/T 36558-2023 for general technical requirements of electrochemical energy storage systems connected to the power system. These Chinese system-level standards have partial technical alignment with IEC 62933 but are not equivalent and are not accepted as substitutes for IEC 62933 evidence by international project owners or financiers.GB/T 36276-2023
GB/T 36558-2023		 IEC 62933 (Electrical energy storage systems) sets system-level functional, safety, and performance requirements for BESS. IEC 62933-2-1 covers unit parameters and testing, IEC 62933-5-2 covers safety requirements for grid-integrated systems. Sri Lanka project owners, PUCSL, and CEB may reference IEC 62933 for system-level BESS performance and safety evidence in utility-scale or commercial storage projects. This standard is in active development and adoption globally; Sri Lanka does not yet have a domestic equivalent.IEC 62933-2-1: Electrical energy storage systems — Unit parameters and testing methods — Part 2-1: General specification
IEC 62933-5-2: Electrical energy storage systems — Safety requirements for grid-integrated energy storage systems
PUCSL / CEB grid-storage connection requirements		 IEC 62933 system-level evidence is increasingly expected by project owners and lenders for utility-scale and commercial BESS in Sri Lanka. Chinese GB/T 36276 and GB/T 36558 reports are domestic evidence only and are not substitutes. Exporters targeting utility-scale Sri Lanka projects should prepare IEC 62933-2-1 performance documentation and IEC 62933-5-2 safety evidence, and engage with PUCSL/CEB on system-level storage technical requirements before project submission.[INFORMATIONAL] Chinese GB/T 36276 and GB/T 36558 system-level evidence does not substitute for IEC 62933 documentation expected by Sri Lanka project stakeholders. Prepare IEC 62933-series performance and safety evidence for utility-scale and commercial BESS projects in Sri Lanka. International Electrotechnical Commission (IEC)2026-06-14 · unverified
Lithium Battery Transport — UN 38.3 and Dangerous Goods Documentation China exporters commonly prepare UN 38.3 reports, MSDS/SDS, transport conditions appraisal reports, and dangerous-goods packaging documents for lithium battery shipments. These documents are required but must match the exact shipped cell or battery configuration — a cell-level UN 38.3 report does not automatically cover a battery module, rack, or containerised system shipped to Sri Lanka.UN 38.3 test report and test summary
SDS / MSDS
Dangerous-goods packaging and transport documents for BESS		 Lithium cells and batteries shipped to Sri Lanka must have UN Manual of Tests and Criteria, Part III, subsection 38.3 test evidence where transport rules require it. Sri Lanka as an island nation receives almost all BESS imports by sea. Exporters should prepare a UN 38.3 test summary, safety data sheet (SDS), dangerous-goods classification, packaging evidence, and IMDG Code sea-transport documentation before shipment. Air transport of large BESS lithium batteries is severely restricted under IATA DGR.UN Manual of Tests and Criteria, Part III, subsection 38.3 (UN 38.3)
IMDG Code for sea transport of dangerous goods
ICAO Technical Instructions / IATA DGR for air transport (large battery restrictions apply)		 UN 38.3 transport evidence is configuration-specific. A test summary covering a cell may not cover a module, rack, or containerised BESS. Sri Lanka importers, port authorities, shipping agents, and carriers may reject inconsistent test summaries, SDS classifications, package marks, or shipping names. Exporters should ensure the UN 38.3 test summary covers the exact BESS configuration shipped, and prepare a complete dangerous-goods package for Colombo port authorities.[INFORMATIONAL] Chinese GB battery safety evidence does not replace UN 38.3 transport documentation. The shipped BESS configuration must be covered by the UN 38.3 test summary and IMDG-compliant dangerous-goods shipping documents.
