Since its inception, the Belt and Road Initiative (BRI) has facilitated the implementation of numerous infrastructure projects in Central Asia, including highways, railways, industrial parks, and urban development projects. Solar street lights, as an important component of green infrastructure, are appearing increasingly frequently in demonstration projects across Central Asia.
However, a practical problem faces all suppliers and contractors involved in such projects: although Central Asian countries are geographically connected, significant differences exist in their technical standards, certification requirements, and procurement specifications. A solar street light product that passes acceptance testing in Kazakhstan may face specification incompatibility issues in projects in Uzbekistan or Kyrgyzstan. Adapting standardized products to the specifications of different countries is one of the core challenges of these projects.
I. Overview of Technical Standards Systems in Central Asian Countries
After independence, the evolution of technical standards systems in Central Asian countries followed different paths, currently resulting in a situation where roughly three systems coexist.
Soviet Standards System (GOST / SNiP)
Kazakhstan, Uzbekistan, and Kyrgyzstan have all adopted, to varying degrees, the GOST standards (national standards) and SNiP specifications (construction specifications) from the Soviet era. These standards clearly stipulate illuminance levels, uniformity, and pole spacing for road lighting, but they lack specific provisions for new technologies such as solar streetlights, and some content is clearly outdated.
International Standards System (IEC/EN)
As countries become more open to the outside world, the recognition of IEC (International Electrotechnical Commission) standards and European EN standards in Central Asia is gradually increasing. Especially in projects involving foreign investment or international financing (such as loans from the Asian Development Bank and the World Bank), products are typically required to comply with IEC or EN standards and hold the corresponding CE or IEC certifications.
Chinese Standards (GB)
"Belt and Road" projects undertaken by Chinese companies sometimes use Chinese national standards (GB standards) as technical basis. Some Chinese suppliers' products have passed CCC certification (China Compulsory Certification) and relevant GB standard testing in China, but the recognition of these certifications in the host Central Asian countries varies depending on the nature of the project and the requirements of the client.
II. Key Certification Requirements for Solar Street Light Products
In the "Belt and Road" projects in Central Asia, solar street light products typically require certifications in the following categories:
Electrical Safety Certification:The Low Voltage Directive (LVD) in CE certification is a fundamental requirement, ensuring the electrical safety of the product within the specified voltage range. For smart street lights containing wireless communication modules, the Radio Equipment Directive (RED) is also required. IEC 62262 (Protection against ingress of foreign solids and liquids, i.e., IP rating) and IEC 62368 (Safety requirements for audio-visual information technology and communication equipment) are common specific standards.
Photometric Performance Certification:The photometric performance of road lighting products typically requires a goniophotometric report issued by an accredited laboratory. The report format should conform to IES LM-79 (for the Americas market) or the European standard EN 13032 (for Europe and most "Belt and Road" international financing projects). Data such as luminous flux, luminous efficacy, and light distribution curve in the report are the basis for lighting design verification. Electromagnetic Compatibility (EMC) Certification
EMC certification ensures that products will not interfere with other electronic devices and possess a certain level of interference immunity. The EMC Directive (EMCD) in CE certification is a European requirement, while GOST R EMC is a requirement for Russia and some CIS countries, and is required in some government projects in Kazakhstan and Uzbekistan.
Photovoltaic Module Certification
The photovoltaic panels (solar panels/photovoltaic modules) in solar streetlights should hold IEC 61215 (Design Qualification and Approval of Crystalline Silicon Photovoltaic Modules) certification. This is a fundamental international certification requirement for photovoltaic module quality and a standard clause on the procurement list of multilateral development bank loan projects.
III. How to Adapt Standardized Products to Different National Standards
Given the differences in standards among Central Asian countries, customizing a product for each country is neither realistic nor economical. A more feasible strategy is to establish a standardized product platform with adaptability, achieving cross-border adaptation through modular design and flexible configuration.
Certification Coverage Strategy: Prioritize obtaining the most internationally recognized certification systems—CE certification (covering EU standards) and IEC certification (covering international electrotechnical standards)—as the foundation for product certification. Based on this, supplementary certifications are obtained to meet the specific requirements of particular markets (such as EAC certification in Kazakhstan, i.e., Eurasian Economic Union certification). This "broad foundation + targeted supplementation" certification strategy can cover major Central Asian markets at a relatively low cost.
Flexible Configuration of Lighting Parameters: Different national standards have varying requirements for illuminance and uniformity in road lighting. Through adjustable controller parameters and replaceable optical lenses, the same luminaire product can be adapted to different lighting design requirements without requiring product redevelopment. Providing a DIALux simulation report for different national standards is an effective way to demonstrate product compliance with local regulations.
Document Localization: Localizing procurement documents and technical documentation is an often overlooked but crucial adaptation process. Translations of product installation manuals, maintenance guides, and certification certificates (Russian is the common working language in Central Asia, and the official status of Kazakh and Uzbek languages is gradually increasing) can significantly lower the barriers to entry for owners and contractors, and are also an important component of the completeness of tender documents.
IV. Characteristics of the Procurement Process for "Belt and Road" Demonstration Projects
Infrastructure projects under the "Belt and Road" framework often have unique procurement processes that differ from purely commercial procurement.
International Competitive Bidding (ICB) is the primary procurement method for large-scale projects. Tender documents have detailed requirements for product technical specifications, certification documents, sample test reports, and reference projects, and often have specific deadlines. Preparing a complete technical documentation package in advance is a fundamental prerequisite for participating in this type of procurement.
Some projects involve third-party inspection agencies to conduct pre-shipment inspections or arrival inspections of the products. Inspection content typically includes sampling tests of appearance, dimensions, electrical parameters, and photometric performance. Familiarity with the testing standards and procedures of common third-party testing organizations (such as SGS, Bureau Veritas, and Intertek) helps to mitigate testing risks in advance.
Local content requirements have emerged in some government projects, requiring a certain percentage of products or services to be provided by local companies. For foreign suppliers, establishing partnerships with local companies not only helps meet local content requirements but also facilitates handling localized matters such as standard certification and customs clearance.
V. Conclusion
The solar street light market in Central Asia along the Belt and Road Initiative presents both vast growth potential and significant regulatory complexity. For companies aiming for long-term growth in this market, investing in certification systems, documentation, and local cooperation networks is a more sustainable competitive strategy than simply competing on price.
Regulatory adaptation is not a one-time task. Technical standards and procurement regulations in Central Asian countries are constantly evolving, especially in Kazakhstan and Uzbekistan, which are accelerating their alignment with international standards. Maintaining continuous attention to local regulatory developments is essential for competitiveness in this market.
