BESS Fire Safety Installation — Guyana Fire Service (GFS), GNBS Code of Practice for Fire Safety, and NFPA Code References 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 from August 1, 2025). GB/T 36558-2023 and GB/T 36276-2023 cover system-level safety including fire-related requirements. Project-level fire-safety review in China is governed by local fire authority approval procedures. Chinese fire-safety standards and domestic approval procedures are not recognised by the Guyana Fire Service or GNBS as equivalent to Guyana's national fire-safety code requirements. BESS fire-safety evidence prepared under Chinese standards must be supplemented with NFPA 855-aligned design documentation — including thermal runaway propagation mitigation, gas detection, ventilation, suppression system design, emergency shutdown, and required separation distances — for GFS and GNBS 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)		 The Guyana Fire Service (GFS) is the authority having jurisdiction for fire safety in Guyana. The Guyana National Bureau of Standards (GNBS) publishes the Code of Practice for Buildings — Fire Safety, Use and Occupancy, which sets mandatory fire-protection requirements for commercial and industrial facilities in Guyana. Buildings must be constructed using fire-resistant materials and must be equipped with built-in warning systems (smoke detectors, sprinklers, alarm systems) to alert occupants and the GFS. GNBS is an ISO/IEC 17025-accredited standards body and a member of CARICOM's Regional Organization for Standards and Quality (CROSQ); Guyana's standards framework draws on IEC and international references. Formal GNBS or GFS adoption of NFPA 855 (Standard for the Installation of Stationary Energy Storage Systems) specifically for stationary BESS has not been confirmed from publicly accessible official sources as of the dataset date — this is a high-priority gap requiring direct verification with the GFS and GNBS before project fire-safety design is finalised. BESS project owners and EPCs in Guyana typically reference NFPA 855 in project specifications given its status as the internationally dominant BESS fire-installation code. The GFS must be engaged for fire-safety design review and approval of commercial and industrial BESS installations before commissioning.GNBS Code of Practice for Buildings — Fire Safety, Use and Occupancy — mandatory fire-safety requirements for commercial and industrial facilities in Guyana (obtain current edition from GNBS)

Guyana Fire Service (GFS) — fire-safety design review and approval authority for commercial and industrial installations		 Gap: GFS fire-safety design review and approval is a mandatory project gate for commercial and industrial BESS installations in Guyana. Chinese BESS fire-safety documentation based on GB standards does not satisfy Guyana's fire-safety code requirements. Exporters and project teams should: (a) confirm directly with GFS and GNBS whether NFPA 855 has been formally adopted as the applicable standard for stationary BESS installations in Guyana, and determine any Guyana-specific requirements or derogations; (b) prepare BESS fire-safety design documentation aligned with NFPA 855 — including thermal-runaway propagation mitigation, gas detection or ventilation design, suppression system design, emergency shutdown procedures, and required separation distances — in accordance with GFS and GNBS requirements; (c) ensure fire-suppression system and detection equipment is listed and certified by an internationally recognised laboratory (UL, FM Global, Bureau Veritas, DNV, or SGS) where required by GFS; (d) engage a fire protection engineer experienced with NFPA codes and Guyana GFS requirements for fire-safety design review before submitting to GFS for project approval; (e) note that Guyana's tropical climate (high humidity, high temperatures) may impose additional equipment derating and protection requirements on battery thermal management systems.[INFORMATIONAL] GFS fire-safety approval is a mandatory installation gate for commercial and industrial BESS in Guyana. Chinese GB-standard fire-safety documentation does not satisfy Guyana's GNBS / GFS fire-safety code requirements. Engage GFS, GNBS, and a fire protection engineer experienced with NFPA 855 at the earliest project stage to confirm the applicable fire code for stationary BESS in Guyana and design requirements before committing to system layout, thermal management system selection, or equipment specification.

GPL Grid Connection for BESS — Mixed-Frequency Grid (60 Hz Coastal DBIS / 50 Hz Legacy Areas), GPL Grid Code, IEEE 1547, and Project-Specific Connection Requirements 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). This differs fundamentally from Guyana's coastal DBIS grid at 60 Hz, 120/240 V. PCS firmware, voltage protection thresholds, frequency ride-through settings, and power factor control parameters configured for China's 50 Hz / 220/380 V grid must be fully reconfigured and retested for Guyana's 60 Hz / 120–240 V coastal grid before installation.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)
GB/T 34120-2017 — 电化学储能系统接入配电网技术规范 (Technical Specification for Electrochemical Energy Storage System Connected to Distribution Network)
NB/T 42090-2016 — 储能变流器检测技术规程 (Technical Code for Testing of Energy Storage Converters)		 Guyana Power and Light Inc. (GPL) is the sole licensed electricity utility in Guyana and operates the transmission and distribution network under a licence from the Public Utilities Commission (PUC). All grid-connected BESS installations require GPL technical review and grid-connection approval under the GPL Grid Code and GPL's Interim Interconnection Requirements. GPL references IEEE 1547 (Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces) and NEC 2014 (Articles 690 and 705) in its renewable energy interconnection guidelines. Installations rated 100 kWac and above are subject to an interconnection assessment in accordance with GPL's Grid Code before approval is granted. A Government Electrical Inspectorate Certificate of Inspection (COI) is also required. CRITICAL GRID PARAMETER — Guyana's grid is not uniform: the coastal Demerara-Berbice Interconnected System (DBIS), where utility-scale and C&I BESS projects are concentrated, operates predominantly at 60 Hz with 120/240 V single-phase and 208/240 V (or 120/208 V three-phase) distribution. Some legacy inland and hinterland areas retain 50 Hz supply. Chinese BESS PCS designed for China's 50 Hz / 220–380 V grid must be reconfigured, re-validated, and re-parameterised for 60 Hz / 120–240 V operation on the coastal DBIS before grid-connection testing and commissioning. GPL's SCADA integration requirement — confirmed for the 2026 PowerChina US$27.3M BESS project at New Sophia and Goedverwagting substations — specifies connection to Guyana's National Control Centre (GNCC) using SCADA, Energy Management, and Automatic Generation Control (AGC) systems. IEC 62933 series may be referenced in GPL project specifications for utility-scale BESS; confirm applicable edition with GPL at the earliest project stage.GPL Grid Code — technical requirements for all generation and storage assets connected to the GPL transmission and distribution network (obtain current version directly from GPL)

Government Electrical Inspectorate — Certificate of Inspection (COI) required for all new electrical installations		 Gap: Chinese GB/T BESS grid-connection certificates and NEA approvals do not satisfy GPL's grid-connection requirements. The most critical technical difference is grid frequency and voltage: (a) Guyana's coastal DBIS operates at 60 Hz / 120–240 V, fundamentally different from China's 50 Hz / 220–380 V — PCS frequency and voltage protection settings, ride-through parameters, reactive power control, and AGC interface must be fully reconfigured and retested for Guyana's grid before commissioning; (b) GPL Grid Code and Interim Interconnection Requirements — engage GPL and the Government Electrical Inspectorate at the earliest project stage to obtain a COI and grid-connection technical requirements before equipment design is finalised; (c) IEEE 1547 compliance — GPL's interconnection guidelines reference IEEE 1547; confirm whether BESS PCS carries IEEE 1547-2018 compliance evidence, or whether project-specific testing is required; (d) IEC 62933 series compliance — where GPL or project-owner specifications require IEC 62933-2-1 or IEC 62933-5-2 evidence, Chinese GB/T standards are not accepted as equivalent; (e) SCADA / AGC integration — the GPL National Control Centre (GNCC) SCADA interface protocol must be confirmed before BMS and EMS design is finalised; (f) confirm whether the specific project site falls within the 60 Hz coastal DBIS or a legacy 50 Hz area, as this determines the PCS configuration scope.[INFORMATIONAL] Chinese GB/T BESS grid-connection compliance and NEA approvals do not satisfy GPL's Guyana grid-connection requirements. The single most important technical gap is the 60 Hz / 120–240 V coastal DBIS grid versus China's 50 Hz / 220–380 V grid — BESS PCS must be fully reconfigured and re-validated for Guyana's grid frequency and voltage before commissioning. Engage GPL and the Government Electrical Inspectorate at the earliest project stage to obtain GPL Grid Code technical requirements, applicable IEEE 1547 and IEC 62933 evidence scope, COI process, and GNCC SCADA integration specifications. Verify whether the project site is on the 60 Hz DBIS coastal grid or a legacy 50 Hz area before finalising PCS equipment selection. Guyana Power and Light Inc. (GPL)2026-06-14 · unverified
Cell and Module Safety — IEC 62619 as International Baseline for Guyana BESS Project Acceptance 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 harmonised with IEC 62619 and are not accepted as equivalents in Guyana project specifications. Exporters must obtain IEC 62619 type-test certificates from an ILAC-accredited laboratory in addition to any Chinese GB compliance. Note that the 2026 GPL/PowerChina BESS project involves Chinese equipment; however, project-level IEC compliance obligations and GPL technical acceptance criteria are determined by the GPL Grid Code and project contract specifications, which are not publicly available as of the dataset date.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)		 Guyana does not currently have a confirmed standalone mandatory BESS product safety regulation equivalent to the EU Battery Regulation or a Saudi SABER/IEC 62619 mandatory conformity route. GNBS (Guyana National Bureau of Standards), established under the Standards Act No. 11 of 1984 and operating under the Ministry of Tourism, Industry and Commerce, is the National Standards Body of Guyana. GNBS is an ISO/IEC 17025-accredited body, participates in CARICOM's CROSQ regional standardisation framework, and draws on IEC international standards in its technical work. No publicly accessible GNBS Technical Regulation specifically mandating IEC 62619 or an equivalent conformity assessment route for BESS cells and modules has been confirmed as of the dataset date. However, IEC 62619 (Safety Requirements for Secondary Lithium Cells and Batteries for Use in Industrial Applications) is the internationally expected safety standard for lithium BESS cells and modules and is expected to be referenced in GPL grid-connection agreements and project specifications for utility-scale and C&I BESS projects in Guyana — as illustrated by the 2026 GPL/PowerChina 60 MWh BESS project (US$27.3M, New Sophia and Goedverwagting substations). IEC 62933-5-2 and IEC 62133 may also be referenced in project specifications for system-level and module-level safety. Exporters should verify the current GNBS regulated product list and confirm IEC evidence requirements with GPL and the project owner before shipment.IEC 62619:2022 — Safety Requirements for Secondary Lithium Cells and Batteries for Use in Industrial Applications (internationally expected baseline for BESS cell/module safety in Guyana project specifications)
IEC 62133-2:2017 — Secondary cells and batteries containing alkaline or other non-acid electrolytes — Safety requirements for portable sealed secondary lithium cells and for batteries made from them (may be referenced for module-level safety)

IEC 62933-5-1:2024 — Electrical Energy Storage Systems — Safety considerations — Hazard identification, risk assessment and risk mitigation
GNBS — Guyana National Bureau of Standards (verify current regulated product list directly; no confirmed mandatory BESS-specific Technical Regulation as of dataset date)		 Critical gap: GPL project specifications and grid-connection agreements 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 project technical specifications. Exporters should: (a) verify the current GNBS regulated-product list for any mandatory pre-shipment conformity obligation; (b) obtain IEC 62619 type-test certificates from an ILAC-accredited laboratory for all cells and modules supplied to Guyana BESS projects; (c) confirm the applicable IEC 62619 edition and any additional IEC 62933-5-2 or IEC 62133 evidence requirements referenced in the GPL connection agreement or project specification before committing to a test programme; (d) note that Guyana's booming BESS procurement activity (GPL/PowerChina 2026 and Bartica BESS upgrade) indicates that GPL's project technical acceptance criteria are evolving — engage GPL directly to confirm current IEC evidence scope before equipment procurement is finalised.[INFORMATIONAL] No confirmed standalone mandatory BESS product safety regulation has been identified for Guyana as of the dataset date; however, IEC 62619 is the internationally expected technical baseline for BESS cell and module safety in GPL project specifications and grid-connection agreements. Chinese GB 44240-2024 and GB/T 36276-2023 certification alone is not sufficient for Guyana project acceptance. Verify GNBS current regulated-product scope and confirm IEC 62619 evidence requirements with GPL, the project owner, and any appointed conformity assessment body before shipment.

UN 38.3 Transport Safety Testing — Mandatory for Lithium Battery Imports to Guyana via Georgetown 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 Guyana 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. For large utility-scale BESS shipments typical of Guyana GPL projects (30–60 MWh), sea freight via container is the expected mode; the test summary must cover the specific packaged configuration being shipped.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 for air freight, IMDG Code for sea freight). Guyana is party to international transport conventions. BESS shipments to Guyana will primarily arrive by sea freight via Georgetown (Guyana's main commercial port on the Atlantic coast), with some inland transport by road thereafter. UN 38.3 requirements apply universally to all lithium battery imports to Guyana by air or sea — there is no Guyana-specific exemption. BESS cells and modules exported from China to Guyana must be covered by a valid UN 38.3 Test Summary from an accredited laboratory before shipment. Exporters should also confirm local Guyana Customs and Trade Administration (GRA) dangerous-goods import documentation requirements with a licensed dangerous-goods shipping agent experienced with Georgetown port procedures.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
IMDG Code — applies to all sea freight of lithium batteries including BESS cells and modules arriving at Georgetown, Guyana
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 Guyana-bound shipments arriving at Georgetown. 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 ILAC-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 with experience in Guyana Georgetown port procedures to confirm IMDG Code packaging, marking, labelling, and documentation requirements for BESS cell and module sea freight shipments, including any Guyana Customs / GRA import declaration requirements for dangerous goods.[INFORMATIONAL] UN 38.3 transport compliance is universal — a Chinese-origin test summary from an accredited laboratory is accepted for Guyana shipments via Georgetown 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 Georgetown port (Guyana's main commercial port) and IMDG Code sea freight procedures to confirm packaging, marking, labelling, and documentation requirements for BESS cell and module shipments to Guyana.
