Vietnam is the third-largest wind market in Asia-Pacific and the fastest-growing in Southeast Asia. With a cumulative installed base of roughly 7.4 GW at end-2025 and a Power Development Plan (PDP8) targeting 26–38 GW onshore and 6 GW offshore by 2030, Vietnam represents the clearest near-term export opportunity for Chinese wind component manufacturers — including the clamps, bolts, and fixings that follow every turbine installation.
§ 01 Market Scale: Where Vietnam Stands
Vietnam's 2030 targets imply adding roughly 19–31 GW of new onshore capacity over five years from a 2025 base of ~7 GW — a build rate that puts it among the top five markets globally by growth rate, even if its absolute volume is a fraction of China's 120 GW annual pace. The offshore target of 6 GW by 2030 has been revised upward in PDP8's April 2025 update, with a longer-term goal of 70–91.5 GW offshore by 2050.
GWEC projects Vietnam will add 21.3 GW of onshore wind between 2025 and 2030 — approximately 2% of global additions over that period, which is a disproportionately large share for a country of Vietnam's economic size. (Source: GWEC Market Outlook Q3 2025 [2])
§ 02 Policy Drivers: Why Now
Three policy developments in 2025 moved Vietnam from "promising market" to "active procurement pipeline":
PDP8 revision (April 2025)
The April 2025 revision to the Power Development Plan updated offshore wind targets upward and extended the buildout horizon to 2035. It confirmed Vietnam's commitment to reaching 10% annual GDP growth, with renewable energy — particularly wind — as a key enabler of grid stability as coal is phased down.
Resolution 253/2025
Passed by the National Assembly in 2025, Resolution 253 allows authorities to approve investment policy and select investors simultaneously for offshore wind projects. This collapses a permitting step that previously added 12–24 months to project timelines. Industry observers expect this to trigger the first commercial offshore wind FIDs (final investment decisions) in Vietnam by 2026–2027. (Source: GWEC [2])
Supply chain localisation mandate
Vietnam's government has set a target to build two manufacturing hubs for wind components by 2030, positioning the country as a regional supply chain centre. China's Power Construction Corporation has already signed a cooperation agreement with Vietnam's Trungnam Group to build a factory in Ninh Thuan Province for wind turbine towers and steel structures.
§ 03 Vietnam vs China: Same Components, Different Context
For a Chinese component supplier, the comparison between these two markets is instructive:
| Factor | China | Vietnam |
|---|---|---|
| Annual new installations | 120 GW (2025) | ~3–5 GW/yr (indicative 2025–2030 pace) |
| Dominant turbine type | 6–10 MW onshore; 10–26 MW offshore | 3–6 MW onshore; 8–12 MW offshore (early projects) |
| OEM landscape | Goldwind, Windey, Mingyang, Envision, SANY dominate | Vestas, Siemens Gamesa historically dominant; Chinese OEMs entering (Shanghai Electric, Windey) |
| Component standards | DIN 3015 (pipe clamps); EN 14399 (bolts) | IEC standards; European OEM specs; Chinese OEM specs for new projects |
| Corrosion environment | C3–C5 (inland to coastal); C5-M (offshore) | C4–C5 (high humidity tropical); C5-M offshore (South China Sea) |
| Supply chain maturity | Fully developed domestic supply chain | Nascent; heavy import reliance for specialised components |
OEM landscape based on US Trade.gov Vietnam Wind Power Sector report and published project data.
The critical difference for procurement: Vietnam's nascent supply chain means that components not locally available must be imported. For specialised items — DIN 3015 pipe clamps in wind-rated EPDM, high-strength tower bolts with mill certificates, corrosion-rated fixings for tropical offshore environments — Vietnam-based EPCs are sourcing from China, Europe, or both. Chinese suppliers who can demonstrate wind-project references and provide compliant documentation are well-positioned to capture this flow.
§ 04 Supply Chain: Chinese OEM Entry Changes the Equation
The entry of Chinese turbine manufacturers into Vietnam is the single most important development for Chinese component suppliers watching this market.
Shanghai Electric
Shanghai Electric's wind subsidiary is supplying turbines to the Hai Anh Wind Farm in Quang Tri Province — one of the first confirmed Chinese OEM turbine deliveries in Vietnam. Where Chinese turbines go, Chinese supply chain specifications follow: DIN 3015 clamps, metric bolt grades, and component documentation in Chinese-standard formats become the baseline rather than the exception.
Windey (运达股份)
Windey began its international expansion with Vietnam orders as early as 2019, making it one of the earliest Chinese OEMs to establish a commercial presence in the country. Its turbine footprint in Vietnam creates a reference base for subsequent Chinese component suppliers.
Tropical corrosion environment
Vietnam's coastal and offshore wind sites sit in a tropical maritime climate: year-round high humidity (85–95% RH indicative), salt-laden air, and temperatures that rarely drop below 20 °C. This affects component selection in two ways:
- Elastomer insert selection — EPDM is the standard for most pipe clamp applications, but the combination of high UV, ozone, and temperature means insert inspection intervals should be tightened vs northern European or Chinese northern desert specifications. Natural rubber should not be substituted.
- Corrosion protection — Offshore sites in the South China Sea require C5-M rated corrosion protection. For clamp bodies and fasteners, this typically means 316L stainless or hot-dip galvanised steel with a duplex paint system, with A4 hardware throughout. Zinc plating alone is insufficient.
§ 05 What This Means for Procurement
Near-term (2025–2027): onshore buildout
Vietnam's onshore pipeline is active now. Projects in the 50–200 MW range are in construction or late development across the central and southern highlands (Ninh Thuan, Binh Thuan, Gia Lai provinces). These projects use 3–5 MW turbines — smaller than the Chinese domestic mainstream — which means:
- Pipe clamp OD ranges are narrower (hydraulic lines are smaller diameter on smaller turbines)
- Tower bolt diameters are smaller (M30–M42 range, indicative), but hot-dip galvanising specifications remain the same
- Project cycle times are faster — procurement windows for a 100 MW onshore project may be 6–12 months from award to delivery
Medium-term (2027–2030): offshore acceleration
If Resolution 253/2025 delivers on its promise to accelerate FIDs, the first commercial offshore projects could enter equipment procurement in 2026–2027. These will be 8–12 MW turbines (indicative, based on current developer preferences) in the Gulf of Tonkin and South China Sea. Procurement for offshore differs significantly from onshore:
- All marine-contact fixings require stainless or duplex body — hot-dip galvanised carbon steel is not adequate for splash zone
- Cable and pipe routing clamps must be A4-rated minimum, with mill-certificate traceability
- Lead times are longer and quantities per project are larger — early engagement with suppliers is critical
§ 06 Sourcing Considerations for Vietnamese Projects
For EPCs and developers sourcing clamps and fasteners for Vietnam wind projects, three questions determine whether a Chinese supplier is appropriate:
1. Does the supplier have wind-project references?
Generic industrial clamp suppliers are not wind-rated. Request references by OEM name and project MW. For a Vietnamese project using a Chinese turbine, a supplier with domestic Chinese wind project references for the same OEM is the strongest qualification.
2. Can the supplier provide tropical-climate documentation?
Vietnam's corrosion environment (C4–C5 onshore, C5-M offshore) requires insert material data sheets showing temperature and UV resistance, and metal component material certificates showing grade and coating weight. "EPDM" on a label is not sufficient — the compound specification and shore hardness matter.
3. What are the MOQ and lead time to Vietnam?
Sea freight from Yancheng (Jiangsu) to Ho Chi Minh City is approximately 5–8 days; to Hanoi/Haiphong 6–10 days. For standard DIN 3015 clamp OD ranges (Ø6–89 mm), ex-stock availability and short lead times are achievable. For large-diameter or custom configurations, 4–8 week lead times apply (indicative).
