Vietnam’s Exclusive Economic Zone boasts over 1,000 GW of wind power potential: report

Vietnam’s Exclusive Economic Zone (EEZ) has a wind power potential of 1,068 GW, nearly 470 GW more than previously estimated, according to a report released Friday by the National Center for Hydro-Meteorological Forecasting (NCHMF).

The report, titled "Detailed Assessment of Wind Resource Potential in Coastal (up to 6 Nautical Miles) and Offshore Areas in Vietnam," was conducted by the NCHMF with support from the United Nations Development Program (UNDP) and the Norwegian Embassy.

This wind potential was measured at a height of 100 meters above sea level, said Mai Van Khiem, director of the NCHMF. He noted that from November to February each year, wind capacity accounts for half of the annual total - peaking in December and gradually decreasing, with the lowest levels recorded in May.

The southern offshore areas account for 894 GW of this potential, while the northern areas contribute 174 GW.

In nearshore zones (up to 6 nautical miles), the total technical wind power potential is 57.8 GW. The Bac Lieu-Ca Mau region alone contributes nearly 30% of this, while the Ninh Thuan-Binh Thuan area accounts for 24 GW. Although the Quang Tri-Hue region has lower potential, it offers stable wind speeds during the winter months. The Red River Delta has a modest potential of 0.17 GW.

Compared to previous assessments, such as the World Bank’s 2021 study and data from the Global Wind Atlas (GWA), this report provides more detailed and higher-resolution information, both spatially and temporally.

“Notably, the EEZ potential outlined in this report exceeds the World Bank’s estimate by 469 GW, primarily due to the broader scope of the survey and more refined climate modeling using domestic observational data,” the research team explained.

They also emphasized the use of the Weather Research and Forecasting (WRF) model customized specifically for Vietnam, which enhanced the accuracy of the results.

The findings are based on wind data collected from 26 coastal and island meteorological stations, satellite sources from CCMP, ASCAT, and SCATSAT-1 (covering 30 years of ocean surface wind data), as well as buoy data from Nghe An province and seabed depth measurements.

A key innovation in this report is the integration of potential impacts from extreme weather events. Typhoons and tropical depressions occurring between August and October pose structural and safety risks to wind turbines. Meanwhile, strong winds and high waves during the northeast monsoon season can hinder access to and maintenance of offshore wind systems.

To support model calibration and long-term observation, the research team recommends increased investment in offshore wind monitoring stations at heights exceeding 100 meters. They also suggest incorporating these findings into offshore wind development strategies and national marine spatial planning.

Additionally, the team advocates for expanding research into other forms of marine renewable energy, such as wave, tidal, and ocean thermal energy.

“Vietnam has some of the most promising offshore wind resources in the region, creating a strong foundation for the development of a large-scale offshore wind industry. This will contribute to energy security, green economic growth, and the achievement of net zero commitments,” they said.

The study provides a vital scientific basis for policy planning, identifying priority development zones, attracting investment, building infrastructure, and training the future offshore wind workforce, the team added.

Hoang Duc Cuong, deputy director of the Department of Meteorology and Hydrology, emphasized that Vietnam lies within a strong and stable Asian monsoon belt, giving it abundant wind energy potential. He noted that this renewable source will play a key role in meeting the country’s climate change goals and advancing a low-carbon economy.

However, he also warned that marine-based natural disasters are highly complex and could significantly impact the stability of offshore wind operations and energy generation.
