With over 3,000 kilometers of coastline, Vietnam holds significant potential for wind power generation. On April 18, Vietnamese authorities released a new report estimating the country’s wind power potential within its exclusive economic zone at 1,068 gigawatts (GW).
The study also identifies the strongest wind regions and time periods, incorporating extreme weather risk assessments, forming a scientific basis for future wind power policy.
Ninh Thuan–Binh Thuan leads in coastal wind potential
The report, titled " Detailed Assessment of Wind Resource Potential in Coastal (up to 6 Nautical Miles) and Offshore Areas in Vietnam," finds that wind strength peaks from November to February each year, with December being the windiest month. Wind speeds then decline, reaching the lowest point in May.
For nearshore areas (within 6 nautical miles), the technical potential is estimated at 57.8 GW. Among these, the Ninh Thuan–Binh Thuan region accounts for 24 GW, over 40% of the total. The Bac Lieu–Ca Mau region contributes nearly 30%, while the Quang Tri–Hue area, though less potent, offers consistent wind speeds. The Red River Delta contributes under 1%.
When categorized by larger regions and based on wind speeds measured at 100 meters above sea level, the southern offshore zone emerges as the key wind energy source with 894 GW of potential, compared to 174 GW in the north.

Offshore wind potential more than expected
The study was conducted by Vietnam’s National Center for Hydro-Meteorological Forecasting (NCHMF). Researchers say the higher-than-expected wind power estimate—469 GW above the World Bank’s figure—is due to broader survey coverage and improved climate modeling using local observational data.
Notably, the report includes an assessment of extreme weather risks. It highlights the impact of typhoons and tropical depressions, particularly between August and October, which could damage wind turbine infrastructure. Strong winds and heavy waves brought by the northeast monsoon also pose challenges for offshore wind system operation and maintenance.
The study was supported by the United Nations Development Programme (UNDP) and the Norwegian Embassy. Patrick Haverman, UNDP’s Deputy Resident Representative in Vietnam, said the report offers the most detailed wind power mapping to date, with high-resolution data and over 30 years of simulation analysis.
It also provides information on topography, coastal geography, marine weather hazards, and sea conditions in Vietnam’s East Sea and coastal zones. These insights are expected to guide investors and policymakers. Vietnam’s government recently approved a revision to its National Power Development Plan (PDP8), targeting offshore wind deployment by 2030 with a total installed capacity goal of 6,000 to 17,032 MW.
