BESS Fire Safety Installation — Jabatan Bomba dan Penyelamat Malaysia (Bomba) Approval and UBBL 1984 Requirements China manages BESS fire safety under a combination of mandatory standards and project-level fire-safety review. GB 44240-2024 includes fire-safety provisions for BESS cells and modules (mandatory, effective August 1, 2025). GB/T 36276-2023 and GB/T 36558-2023 cover system-level safety including fire-related requirements. Project-level fire-safety review in China is governed by local fire authority approval procedures under the Fire Protection Law of the People's Republic of China. These Chinese fire-safety standards and domestic approval procedures are not recognised by Bomba as equivalent to Malaysia's UBBL 1984 and NFPA-referenced fire-safety installation requirements. BESS fire-safety evidence prepared under Chinese standards must be supplemented with documentation aligned to Malaysian requirements for Bomba project review.GB 44240-2024 — 电化学储能系统用二次锂电池安全要求 (includes fire-safety provisions for BESS cells/modules; mandatory, effective August 1, 2025)
GB/T 36558-2023 — 电力系统电化学储能系统通用技术条件 (General Technical Requirements for Electrochemical Energy Storage Systems in Power Systems)		 Jabatan Bomba dan Penyelamat Malaysia (Bomba — Fire and Rescue Department of Malaysia) is the fire safety authority having jurisdiction for building fire safety approvals in Malaysia, under the Fire Services Act 1988 (Act 341). Bomba fire-safety approval is a mandatory project gate for all commercial and industrial facilities, including BESS installations. The Uniform Building By-Laws 1984 (UBBL 1984) — made under the Street, Drainage and Building Act 1974 — sets minimum fire-safety requirements for buildings in Peninsular Malaysia (Sabah and Sarawak have separate building laws). Bomba's technical references include MS 1183 (Code of Practice for Fire Protection — various parts), and NFPA codes may be referenced in project specifications for stationary BESS. NFPA 855 (Standard for the Installation of Stationary Energy Storage Systems) is the internationally dominant BESS fire-installation code; formal Bomba adoption of NFPA 855 specifically for stationary BESS has not been confirmed from publicly accessible official sources as of the dataset date — direct Bomba verification is required before project design is finalised. For utility-scale BESS installations, Bomba plan scrutiny and Certificate of Completion and Compliance (CCC) from local authorities are required. A Bomba-accredited fire-protection engineer should be engaged for design review and submission.Fire Services Act 1988 (Act 341) — Malaysia statutory basis for Bomba fire-safety jurisdiction
Uniform Building By-Laws 1984 (UBBL 1984) — minimum fire-safety requirements for buildings in Peninsular Malaysia (made under Street, Drainage and Building Act 1974)
MS 1183 — Malaysian Standard: Code of Practice for Fire Protection (various parts; Bomba technical reference)
NFPA 855 — Standard for the Installation of Stationary Energy Storage Systems (internationally dominant BESS fire-installation code; Bomba formal adoption specifically for BESS unconfirmed as of dataset date — verify directly with Bomba)
IEC 62933-5-1:2024 — Electrical Energy Storage Systems — Safety considerations — Hazard identification, risk assessment and risk mitigation (system-level safety standard expected in project specifications)		 Gap: Bomba fire-safety installation approval is a mandatory project gate for all commercial and industrial BESS installations in Malaysia. Chinese BESS fire-safety documentation based on GB standards does not satisfy Bomba's requirements under UBBL 1984 and Malaysian fire codes. Exporters and project teams should: (a) confirm directly with Bomba the applicable fire code and standard for stationary BESS installations — including whether NFPA 855 or MS 1183 (or a local adaptation) applies — and determine any Malaysia-specific requirements or additional conditions; (b) prepare BESS fire-safety design documentation aligned with Bomba requirements — including thermal-runaway propagation mitigation, gas detection or ventilation design, fire suppression system design, emergency shutdown procedures, and separation distances; (c) ensure fire-suppression system equipment is certified by an accredited laboratory acceptable to Bomba; (d) engage a Bomba-registered fire protection engineer (Jurutera Keselamatan Kebakaran) for design review and application submission; (e) obtain CCC sign-off from local authority (Pihak Berkuasa Tempatan) before commissioning.[INFORMATIONAL] Bomba fire-safety approval is a mandatory installation gate for commercial and industrial BESS in Malaysia. Chinese GB-standard fire-safety documentation does not satisfy Malaysia's Bomba requirements under UBBL 1984 and Malaysian fire codes. Engage Bomba and a registered fire protection engineer at the earliest project stage to confirm the applicable fire code for stationary BESS (including whether NFPA 855 or MS 1183 applies) and design requirements before committing to system layout or equipment specification. Local authority CCC sign-off is required before commissioning. Jabatan Bomba dan Penyelamat Malaysia (Fire and Rescue Department of Malaysia)2026-06-14 · unverified
Malaysia Grid Connection for BESS — ST Grid Code, TNB Connection Requirements, and 50 Hz System China's grid-connection requirements for BESS are governed by GB/T 36558-2023 (General Technical Requirements for Electrochemical Energy Storage Systems in Power Systems) and GB/T 34120-2017 (Technical Specification for Electrochemical Energy Storage System Connected to Distribution Network). The PCS (energy storage converter) is assessed under NB/T 42090-2016 (Technical Code for Testing of Energy Storage Converters). Chinese BESS products are validated by grid operators through National Energy Administration (NEA)-authorised procedures. China's grid operates at 50 Hz, 220/380 V (220 V single-phase, 380 V three-phase) — different from Malaysia's 240/415 V (LV). PCS firmware and voltage protection parameters configured for China's 220/380 V grid must be re-parameterised for Malaysia's 240/415 V, 50 Hz grid conditions before grid-connection testing and commissioning.GB/T 36558-2023 — 电力系统电化学储能系统通用技术条件 (General Technical Requirements for Electrochemical Energy Storage Systems in Power Systems)

NB/T 42090-2016 — 储能变流器检测技术规程 (Technical Code for Testing of Energy Storage Converters)		 Suruhanjaya Tenaga (ST), the Energy Commission of Malaysia, is the statutory regulator under the Electricity Supply Act 1990 (ESA 1990). All grid-connected generation and storage facilities in Peninsular Malaysia and Sabah require an ST licence or exemption under the ESA 1990. Tenaga Nasional Berhad (TNB) is the transmission and distribution system operator in Peninsular Malaysia. BESS installations connected to the TNB distribution or transmission network require TNB grid-connection approval and must comply with the TNB Connection and Use of System Code (CUSC) and the Grid Code (Peninsular Malaysia). Malaysia's grid operates at 50 Hz ±0.5 Hz (240 V single-phase, 415 V three-phase for low-voltage distribution; 11 kV and above for medium and high voltage). BESS power conversion systems (PCS) — bidirectional inverters — must be configured and validated for Malaysia's 50 Hz grid parameters. IEC 62933 series standards (including IEC 62933-2-1 and IEC 62933-5-2) may be referenced in utility-scale BESS project technical specifications and TNB connection agreements. Malaysia utility-scale BESS is an emerging sector; TNB has conducted BESS tenders under the national energy transition roadmap. Project-specific ST licensing conditions and TNB connection agreement technical requirements must be obtained directly from ST and TNB for each project.Electricity Supply Act 1990 (ESA 1990) — Malaysia statutory framework for electricity licensing; ST is the regulator

Malaysia grid parameters: 50 Hz ±0.5 Hz, 240 V single-phase, 415 V three-phase (LV); 11 kV / 33 kV / 132 kV / 275 kV (MV/HV)		 Gap: Chinese GB/T BESS grid-connection certificates and NEA approvals do not satisfy ST licensing requirements or TNB grid-connection requirements in Malaysia. Key gaps requiring attention: (a) ST licence — any entity operating a generation or storage facility exceeding the ESA 1990 exemption threshold requires an ST licence; obtain ST pre-project guidance on BESS licensing category; (b) grid voltage — Malaysia LV is 240/415 V whereas China is 220/380 V; PCS voltage protection thresholds, ride-through settings, and reactive power capability must be reconfigured and retested for Malaysia's grid parameters; (c) TNB project-specific connection agreement — engage TNB at the earliest project stage to obtain the applicable CUSC/Grid Code technical requirements before equipment design is finalised; (d) IEC 62933 series — where project specifications or TNB connection agreement require IEC 62933-2-1 or IEC 62933-5-2 evidence, Chinese GB/T standards are not accepted as equivalent; (e) communication protocols — confirm the SCADA/communication interface protocol required by TNB for BESS monitoring.[INFORMATIONAL] Chinese GB/T BESS grid-connection compliance and NEA approvals do not satisfy Malaysia ST licensing or TNB grid-connection requirements. BESS PCS must be re-parameterised for Malaysia's 240/415 V at 50 Hz grid. Obtain ST pre-project guidance on BESS licensing category and engage TNB at the earliest project stage to determine CUSC/Grid Code technical requirements, applicable IEC 62933 evidence, and SCADA/communication protocol specifications. Malaysia utility-scale BESS is an emerging sector — project-specific ST and TNB requirements must be confirmed directly before equipment procurement is finalised.

Cell and Module Safety — SIRIM Certification, IEC 62619, and IEC 62133 for Malaysia BESS China's primary mandatory standard for BESS cells from August 2025 is GB 44240-2024 (Secondary Lithium Cells and Batteries Used in Electrical Energy Storage Systems — Safety Requirements), which replaces the prior GB/T 36276 series as the mandatory safety baseline for large-format BESS batteries over 100 kWh. The prior voluntary standard GB/T 36276-2023 (Lithium-Ion Batteries for Electrical Energy Storage) provides the technical framework for cells, modules, and battery clusters used in EES. These Chinese standards are not accepted as equivalents to IEC 62619 or IEC 62133 in Malaysia project specifications or SIRIM certification. Exporters must obtain IEC 62619 test evidence from an ILAC-accredited laboratory in addition to any Chinese GB compliance.GB 44240-2024 — 电化学储能系统用二次锂电池安全要求 (Secondary Lithium Cells and Batteries Used in Electrical Energy Storage Systems — Safety Requirements; mandatory, effective August 1, 2025)
GB/T 36276-2023 — 电力储能用锂离子电池 (Lithium-Ion Batteries for Electrical Energy Storage; voluntary, effective July 1, 2024)		 SIRIM Berhad is Malaysia's national standards body and a government-linked company that provides product testing and certification services for the Malaysian market. SIRIM operates the SIRIM Certification Scheme for electrical and electronic products; a SIRIM certification mark indicates compliance with the applicable Malaysian Standard (MS) or adopted international standard. For lithium batteries and BESS, SIRIM and Suruhanjaya Tenaga (ST) may require evidence of compliance with IEC 62619 (Safety Requirements for Secondary Lithium Cells and Batteries for Use in Industrial Applications) for industrial/utility-scale BESS cells and modules, and IEC 62133 (Safety Requirements for Portable Sealed Secondary Lithium Cells and Batteries) for smaller cells. IEC 62933-5-2 (Safety Requirements for Electrochemical-based Energy Storage Systems) may be required at the system level. Malaysia does not currently have a confirmed standalone mandatory BESS product certification regulation equivalent to the EU Battery Regulation. The practical expectation for utility-scale BESS projects tendered by TNB is IEC 62619 compliance evidence from an ILAC-accredited laboratory. Exporters should verify the current SIRIM and ST regulated-product scope for BESS before shipment, as Malaysia's BESS regulatory framework is evolving.IEC 62619:2022 — Safety Requirements for Secondary Lithium Cells and Batteries for Use in Industrial Applications (internationally expected baseline for BESS cell/module safety; expected in Malaysia utility-scale project specifications)
IEC 62133-2:2017 — Safety Requirements for Portable Sealed Secondary Lithium Cells and Batteries (applicable to smaller lithium cells; SIRIM certification reference)
IEC 62933-5-2 — Electrical Energy Storage Systems — Safety Requirements — Electrochemical-based systems (system-level safety standard expected in project specifications)
IEC 62040-1 — Uninterruptible Power Systems — General and Safety Requirements (referenced for BESS power conversion systems in some project specifications)
SIRIM Berhad — Malaysia national standards body and certification authority; verify current regulated-product list and applicable MS or IEC standard adoption for BESS before shipment
Suruhanjaya Tenaga (ST) — verify any ST-specific BESS equipment certification requirements		 Critical gap: Malaysia project owners, TNB tenders, and SIRIM certification reference IEC 62619 as the expected safety evidence for BESS cells and modules. Chinese GB 44240-2024 and GB/T 36276-2023 are not harmonised with IEC 62619 and are not accepted as substitutes in Malaysia project technical specifications or SIRIM certification. Exporters should: (a) verify the current SIRIM regulated-product list and any ST equipment certification requirements for BESS before shipment; (b) obtain IEC 62619 type-test certificates from an ILAC-accredited laboratory for cells and modules supplied to Malaysia BESS projects; (c) confirm whether IEC 62133 or IEC 62133-2 is also required for the specific cell form factor and chemistry; (d) confirm the applicable IEC 62619 and IEC 62933-5-2 editions referenced in the project specification or TNB tender requirements before committing to a test programme; (e) note that Malaysia's BESS regulatory framework is evolving — additional mandatory certification requirements may be introduced.[INFORMATIONAL] No confirmed standalone mandatory BESS product certification regulation has been identified for Malaysia as of the dataset date; however, IEC 62619 is the internationally expected technical baseline for BESS cell and module safety in Malaysia project specifications and TNB tenders. Chinese GB 44240-2024 and GB/T 36276-2023 certification alone is not sufficient for Malaysia project acceptance or SIRIM certification. Verify SIRIM current regulated-product scope and ST requirements, and confirm IEC 62619 evidence requirements with the project owner, TNB, and any appointed conformity assessment body before shipment. Malaysia's BESS regulatory framework is evolving — allow additional lead time for certification if regulatory changes occur.

UN 38.3 Transport Safety Testing — Mandatory for Lithium Battery Imports to Malaysia Chinese BESS cell and module manufacturers are required to comply with UN 38.3 for export shipments under international transport conventions. Chinese manufacturers typically hold UN 38.3 test reports and test summaries from CNAS-accredited testing laboratories such as UL, SGS, Bureau Veritas, TÜV, or CAICT. The UN 38.3 Test Summary (required since January 1, 2020) must cover the specific cell or battery type being shipped. A Chinese-origin UN 38.3 test summary from an accredited laboratory is acceptable for Malaysia imports — the key gap is ensuring the test summary covers the specific cell model, chemistry, capacity, and configuration of the BESS units being shipped, and that it is maintained current with any cell design changes.UN 38.3 test reports and test summaries from CNAS-accredited Chinese laboratories (CAICT, UL China, SGS China, Bureau Veritas China, TÜV Rheinland China) — acceptable for international transport if the test summary covers the specific cell/battery type being shipped UN 38.3 (Recommendations on the Transport of Dangerous Goods — Manual of Tests and Criteria, Part III, Section 38.3) specifies eight mandatory transport safety tests (T1 Altitude Simulation, T2 Thermal Test, T3 Vibration, T4 Shock, T5 External Short Circuit, T6 Impact/Crush, T7 Overcharge, T8 Forced Discharge) for lithium metal and lithium-ion cells and batteries of all sizes, including cells, modules, and battery packs used in stationary BESS. Since January 1, 2020, a UN 38.3 Test Summary is mandatory documentation that must accompany lithium battery shipments under international transport regulations (IATA DGR, IMDG Code, ADR). Malaysia is served by major international shipping routes through Port Klang and Penang Port and international air cargo through Kuala Lumpur International Airport (KLIA). Malaysia is a party to international transport conventions, and the UN 38.3 requirement applies universally to all lithium battery imports by air, sea, or road — there is no Malaysia-specific exemption. BESS cells and modules exported from China to Malaysia must be covered by a valid UN 38.3 Test Summary from an accredited laboratory before shipment. Malaysia's CIDB (Construction Industry Development Board) or DOSH (Department of Occupational Safety and Health) may have additional on-site handling requirements for BESS during installation — verify with the relevant authority.UN 38.3 — Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part III, Section 38.3 (mandatory transport safety tests T1–T8 for all lithium cells and batteries)
IATA Dangerous Goods Regulations (DGR) — applies to all air freight of lithium batteries including BESS cells and modules via KLIA and other Malaysian airports
IMDG Code — applies to all sea freight of lithium batteries including BESS cells and modules via Port Klang and Penang Port
UN Model Regulations, 7th revised edition (2021) — Test Summary requirement in force since January 1, 2020		 The gap is documentation scope and currency, not standard equivalence. UN 38.3 is a universal requirement and Chinese-origin test summaries from accredited laboratories are accepted for Malaysia-bound shipments. Exporters should verify: (a) the UN 38.3 test summary covers the specific cell model (including chemistry, capacity, and format) being exported — a summary for a different cell model or capacity is not transferable; (b) the test summary is from a currently accredited laboratory; (c) any cell design change (electrolyte, separator, electrode, BMS firmware affecting charge/discharge) since the original UN 38.3 testing triggers a reassessment requirement; (d) module-level and battery-pack-level assemblies may require separate UN 38.3 assessment if they constitute a battery as defined under international transport regulations; (e) engage a dangerous-goods shipping agent familiar with Port Klang (Westports / Northport), Penang Port, and KLIA DG regulations to confirm packaging, marking, labelling, and documentation requirements for BESS cell and module shipments to Malaysia.[INFORMATIONAL] UN 38.3 transport compliance is universal — a Chinese-origin test summary from an accredited laboratory is accepted for Malaysia shipments provided it covers the specific cell model and is current. The primary risk is scope mismatch (wrong cell model or capacity in the summary) or an outdated summary after a cell design change. Verify test summary coverage and currency before each shipment. Engage a dangerous-goods shipping agent familiar with Malaysia port (Port Klang / Penang Port) and aviation (KLIA) DG regulations to confirm packaging, marking, labelling, and documentation requirements for BESS cell and module shipments.
