BESS Fire Safety Installation — Bomberos Paraguay and Local Building Authority 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, 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. These Chinese fire-safety standards and domestic approval procedures are not recognised by Bomberos Paraguay or local building authorities as equivalent to Paraguay's applicable fire-safety installation requirements. BESS fire-safety evidence prepared under Chinese standards must be supplemented with IEC 62933-5-2 and IEC 62619-aligned design documentation for Paraguay 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)		 Fire safety for BESS installations in Paraguay is governed by Bomberos Paraguay (the national fire service) and the relevant local municipal building authority (intendencia municipal). There is no single confirmed standalone national BESS fire-safety installation regulation in Paraguay as of the dataset date. Fire-safety requirements for commercial and industrial BESS installations are determined at the project level through Bomberos Paraguay approval and local building permit processes. IEC 62933-5-2 (Safety Requirements for Electrochemical-based Energy Storage Systems) and IEC 62619 (Safety Requirements for Secondary Lithium Cells and Batteries for Use in Industrial Applications) are the internationally expected technical references for BESS fire and safety design in Paraguay project specifications. Exporters and project teams should engage Bomberos Paraguay and the local municipal authority at the earliest project stage to confirm applicable fire-safety requirements, design documentation expectations, suppression system specifications, and any mandatory equipment certification requirements before project design is finalised.IEC 62933-5-2 — Electrical Energy Storage Systems — Safety Requirements — Electrochemical-based systems (internationally expected technical reference for BESS fire-safety design in Paraguay project specifications)
IEC 62619:2022 — Safety Requirements for Secondary Lithium Cells and Batteries for Use in Industrial Applications (cell and module safety baseline referenced in project specifications)
Bomberos Paraguay — national fire service; project-level fire-safety approval required for commercial and industrial BESS installations
Local municipal building authority (intendencia municipal) — building permit and fire-safety installation approval at project level		 Gap: Bomberos Paraguay and local building authority fire-safety installation approval are mandatory project gates for commercial and industrial BESS installations in Paraguay. Chinese BESS fire-safety documentation based on GB standards does not satisfy Paraguay's applicable fire-safety requirements. Exporters and project teams should: (a) engage Bomberos Paraguay and the relevant local municipal authority (intendencia municipal) at the earliest project stage to confirm applicable fire codes, design documentation requirements, and any mandatory equipment or suppression system certifications; (b) prepare BESS fire-safety design documentation aligned with IEC 62933-5-2 and IEC 62619 — including thermal-runaway propagation mitigation, gas detection or ventilation design, suppression system design, emergency shutdown procedures, and separation distances; (c) confirm whether internationally accredited laboratory certifications (UL, FM Global, Bureau Veritas, DNV, SGS) are required by the project owner or building authority for fire-suppression equipment; (d) engage a locally licensed fire protection engineer for design review and permit application submission.[INFORMATIONAL] Bomberos Paraguay and local municipal building authority fire-safety approval are mandatory installation gates for commercial and industrial BESS in Paraguay. Chinese GB-standard fire-safety documentation does not satisfy Paraguay's applicable requirements. Engage Bomberos Paraguay and the relevant local municipal authority at the earliest project stage to confirm the applicable fire-safety requirements and design documentation expected for BESS installations before committing to system layout or equipment specification.

ANDE Grid Connection for BESS — 220/380 V 50 Hz System, IEC 62933, 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 34120-2023 (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 also operates at 50 Hz, 220/380 V (220 V single-phase, 380 V three-phase) — nominally the same voltage as Paraguay, which removes the voltage reconfiguration gap present in other export markets. However, PCS protection thresholds, ride-through settings, communication protocols, and SCADA interface requirements must still be confirmed with ANDE, as Chinese NEA grid approvals are not transferable to Paraguay.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 34120-2023 — 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)		 ANDE (Administración Nacional de Electricidad) is Paraguay's state vertically-integrated monopoly electricity utility and the de-facto sector authority. There is no separate independent electricity regulator in Paraguay. All grid-connected BESS installations — including utility-scale, distributed solar-paired, and behind-the-meter projects — require ANDE technical review and grid-connection approval. Paraguay's grid operates at 220/380 V (220 V single-phase, 380 V three-phase) at 50 Hz, supplied primarily from the binational hydropower plants Itaipú (Paraguay–Brazil) and Yacyretá (Paraguay–Argentina), which together produce a significant electricity surplus. Interest in BESS for distributed solar integration and grid services is emerging but the market remains very nascent. Specific BESS grid-connection requirements are defined in project-level connection agreements with ANDE. These may reference IEC 62933 (Electrical Energy Storage Systems) series standards including IEC 62933-5-2 (Safety Requirements for electrochemical-based systems) and IEC 62933-2-1 (Unit Parameters and Testing Methods). A publicly accessible ANDE technical specification document specifically for BESS grid connection had not been confirmed as of the dataset date; project-specific connection agreement terms must be obtained directly from ANDE.ANDE (Administración Nacional de Electricidad) — mandatory grid-connection approval for all grid-connected BESS in Paraguay; ANDE is the sole vertically-integrated utility and de-facto sector authority with no separate independent regulator

Paraguay grid parameters: 220 V single-phase, 380 V three-phase, 50 Hz		 Gap: Chinese GB/T BESS grid-connection certificates and NEA approvals do not satisfy ANDE's grid-connection requirements. Key points requiring attention: (a) voltage nominal alignment — Paraguay and China both use 220/380 V 50 Hz, which removes the voltage reconfiguration gap seen in other markets; however, grid tolerance bands, protection relay settings, and ride-through requirements must still be confirmed with ANDE; (b) ANDE project-specific connection agreement terms — engage ANDE at the earliest project stage to obtain applicable technical requirements before equipment design is finalised; (c) IEC 62933 series compliance — where ANDE or project specifications require IEC 62933-2-1 or IEC 62933-5-2 evidence, prepare test and design documentation accordingly, as Chinese GB/T standards are not accepted as equivalent; (d) communication protocols — confirm the SCADA or communication interface protocol required by ANDE for BESS monitoring (IEC 61850, DNP3, Modbus, or project-specific specification); (e) ANDE's BESS framework is nascent — expect requirements to evolve and confirm the latest applicable technical conditions before equipment procurement is finalised.[INFORMATIONAL] Chinese GB/T BESS grid-connection compliance and NEA approvals do not satisfy ANDE's Paraguay grid-connection requirements. The nominal voltage alignment (220/380 V 50 Hz in both countries) removes the voltage reconfiguration gap seen in other markets, but ANDE project-specific connection agreement terms, IEC 62933 evidence requirements, and SCADA/communication protocol specifications must still be confirmed. Engage ANDE at the earliest project stage. No publicly accessible ANDE technical specification specifically for BESS grid connection has been confirmed as of the dataset date — direct ANDE engagement is essential before equipment procurement is finalised.

Cell and Module Safety — IEC 62619 as International Baseline for Paraguay BESS Project Acceptance via INTN Conformity 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 in Paraguay project specifications or INTN conformity assessment. 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)		 Paraguay does not currently have a confirmed standalone mandatory BESS product safety regulation equivalent to the EU Battery Regulation or a dedicated national BESS technical regulation. INTN (Instituto Nacional de Tecnología, Normalización y Metrología) is the national standardisation body responsible for developing and maintaining Paraguay's national standards (NP norms). INTN adopts IEC international standards by reference as NP norms and operates a conformity assessment system. ANDE (the state electricity utility and de-facto sector authority) may reference INTN-adopted IEC standards in project technical specifications and connection agreement requirements. IEC 62619:2022 (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. IEC 62933-5-1:2024 (Electrical Energy Storage Systems — Safety considerations — Hazard identification, risk assessment and risk mitigation) is the expected system-level complement. Exporters should verify the current INTN regulated-product scope and any mandatory conformity assessment obligations directly with INTN 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 Paraguay project specifications, adopted by reference as INTN NP norm)

INTN (Instituto Nacional de Tecnología, Normalización y Metrología) — Paraguay national standardisation body; conformity assessment via INTN NP norm adoption of IEC standards; verify current regulated product scope directly with INTN		 Critical gap: Paraguay project owners and ANDE connection agreements reference IEC 62619 as the expected safety evidence for BESS cells and modules. INTN conformity assessment adopts IEC standards by reference as NP norms, and IEC 62619 is the internationally expected baseline. 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 or INTN conformity assessment. Exporters should: (a) verify the current INTN regulated-product list for any mandatory pre-shipment conformity assessment obligation; (b) obtain IEC 62619 type-test certificates from an ILAC-accredited laboratory for cells and modules supplied to Paraguay BESS projects; (c) confirm the applicable IEC 62619 edition and any NP norm version referenced in the project specification, ANDE connection agreement, or INTN conformity scope before committing to a test programme.[INFORMATIONAL] No confirmed standalone mandatory BESS product safety regulation has been identified for Paraguay as of the dataset date; however, IEC 62619 is the internationally expected technical baseline for BESS cell and module safety in Paraguay project specifications and ANDE connection agreements, adopted by reference through INTN NP norm adoption of IEC standards. Chinese GB 44240-2024 and GB/T 36276-2023 certification alone is not sufficient for Paraguay project acceptance. Verify INTN current regulated-product scope and confirm IEC 62619 evidence requirements with the project owner, ANDE, and any appointed conformity assessment body before shipment.

UN 38.3 Transport Safety Testing — Mandatory for Lithium Battery Imports to Paraguay; Landlocked Routing via Paraná Hidrovía and Argentine or Brazilian Ports 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 Paraguay-bound shipments. The primary gap for Paraguay is not standard equivalence but multimodal routing complexity: BESS cargo from China must transit at least one of Argentina or Brazil before reaching Paraguay, and dangerous-goods documentation must comply with each transit country's applicable international dangerous-goods regulations across sea, road, and potentially river barge legs.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). Paraguay is landlocked and all BESS imports from China arrive via multimodal logistics: either (a) sea freight to Argentine ports (Buenos Aires / Zárate / Rosario) followed by river or road transport to Paraguay; (b) sea freight to Brazilian ports (Santos / Paranaguá) followed by road transport to Paraguay; or (c) river barge via the Paraná–Paraguay hidrovía waterway. Each routing mode activates the relevant international dangerous-goods convention (IMDG Code for sea legs, ADR or domestic DG road regulations for road legs, UNECE riverine DG rules for waterway legs). A UN 38.3 Test Summary from an accredited laboratory is required before shipment. Exporters must engage a dangerous-goods logistics specialist with experience in Paraguayan import routing to ensure compliant multimodal documentation across all transit jurisdictions.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)
IMDG Code — applies to all sea freight of lithium batteries including BESS cells and modules (sea legs via Argentine or Brazilian ports)
ADR — European Agreement concerning the International Carriage of Dangerous Goods by Road (applies to road legs through Argentina or Brazil if those countries apply ADR-aligned national regulations)
UNECE European Agreement concerning the International Carriage of Dangerous Goods by Inland Waterways (ADN) — applies to river barge transport on the Paraná–Paraguay hidrovía waterway where applicable
UN Model Regulations, 7th revised edition (2021) — Test Summary requirement in force since January 1, 2020		 The gap for Paraguay is multimodal routing complexity and documentation scope, not standard equivalence. UN 38.3 is a universal requirement and Chinese-origin test summaries from accredited laboratories are accepted for Paraguay-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 since the original UN 38.3 testing triggers a reassessment requirement; (d) multimodal routing documentation: engage a dangerous-goods logistics specialist with experience routing cargo from China through Argentine or Brazilian ports to Paraguay via road or the Paraná–Paraguay hidrovía waterway — each leg (IMDG sea, ADR road, ADN or national waterway rules) requires compliant DG documentation; (e) Paraguay Customs (DNA — Dirección Nacional de Aduanas) import requirements for lithium batteries, including any pre-shipment or customs declaration obligations.[INFORMATIONAL] UN 38.3 transport compliance is universal — a Chinese-origin test summary from an accredited laboratory is accepted for Paraguay-bound shipments provided it covers the specific cell model and is current. The primary risk for Paraguay shipments is multimodal routing complexity: cargo must transit Argentina or Brazil (or both) before reaching Paraguay, and each logistics leg activates different international dangerous-goods conventions. Engage a dangerous-goods logistics specialist with Paraguay routing experience before shipment. Verify test summary coverage and currency, and confirm DNA (Paraguay Customs) import documentation requirements for lithium battery cargo.
