In the context of fossil fuel resources such as coal, oil, and natural gas gradually depleting, offshore wind power is emerging as a crucial renewable energy solution for the future. With a coastline stretching over 3,260 km and enormous offshore wind potential, Vietnam is facing a great opportunity to develop the offshore wind power industry, contributing to the realization of the national green energy transition goals.
Offshore Wind Power: Global Trends and Opportunities for Vietnam
History of offshore wind power development worldwide
The first offshore wind power project was installed in Denmark in 1991, marking an important turning point in the history of renewable energy. Since then, commercial-scale offshore wind farms have developed strongly worldwide, especially in Europe.
Thanks to breakthrough advances in turbine manufacturing technology, the investment cost of offshore wind power has dropped sharply to about 6-8 cents/kWh, making this energy source competitive with traditional fossil fuel sources. Modern wind turbines are manufactured with advanced engineering technology, ensuring high longevity and the ability to withstand harsh conditions at sea.
Vietnam’s offshore wind power potential
According to Dr. Du Van Toan from the Institute of Marine and Island Research under the General Department of Seas and Islands (Ministry of Natural Resources and Environment), wind energy resources are the newest and fastest-growing energy source in the world today.
Vietnam possesses extremely abundant wind resources with impressive figures:
- Total wind power potential: 513,360 MW – the largest in Southeast Asia
- Potential capacity: 200 times the capacity of Son La hydropower plant
- Compared to electricity sector forecast: More than 10 times the total forecast capacity for 2020

- Wind energy density: 1,200-1,400 W/m²
- Ideal conditions for large-scale offshore wind power development
2. Khanh Hoa: Enormous potential
- Longest coastline: 370 km
- Sea surface area: 37,000 km²
- Wind energy resources: 259,000 MW (highest in the country)
- Including the Spratly Islands
3. Ca Mau: Rich potential in the far south

- Sea surface area: 25,400 km²
- Wind energy resources: 203,200 MW
4. Binh Thuan: Wind energy center
- Coastline: 192 km
- Sea surface area: 19,200 km²
- Wind resources: 172,800 MW
5. Special areas
Phu Quy Island, Bach Long Vi, and the Spratly Islands also possess high wind energy resources, suitable for establishing large offshore wind power projects.
Current Status of Offshore Wind Power Development in Vietnam
Initial phase (2015-2019)
- 2015: Bac Lieu nearshore wind power project with 99.6 MW capacity became operational
- 2017: Nearshore wind power projects in Ca Mau, Soc Trang, Ben Tre, Tra Vinh, Tien Giang, Ba Ria – Vung Tau
- 2019: Ke Ga wind power project (Thanglong Wind) with 3.4 GW capacity, total investment of 12 billion USD approved by the Government for feasibility study
Boom with FIT mechanism (2020-2021)
With the Feed-in Tariff (FIT) policy of 9.8 cents/kWh for 20 years committed by EVN, Vietnam’s offshore wind power sector developed strongly:
- As of October 30, 2021: 84 projects fully or partially operational
- Total installed capacity: Approximately 4 GW
- Number of registered projects: About 15 GW
Draft Power Development Plan VIII: Ambitious vision
According to the Draft Power Development Plan VIII (April 2022 version), the Ministry of Industry and Trade set ambitious targets:
By 2030:
- Onshore and nearshore wind power: 16 GW
- Offshore wind power: 7 GW
By 2045:
- Total wind power capacity: 122 GW
- Of which offshore wind power: 66 GW
International vision
The World Bank’s “Offshore Wind Roadmap to 2050” group proposes a target of 70 GW for Vietnam with offshore wind power prices reaching 5 cents/kWh. If achieved, Vietnam will:
- Rank 3rd in Asia for wind power capacity
- Only behind China and Japan
- Surpass South Korea, Philippines, Indonesia
It is estimated that by 2050, offshore wind power can meet nearly 30% of Vietnam’s electricity demand, possibly even higher depending on the market and technological progress.
Challenges in Offshore Wind Power Development
1. Project implementation timeline
An offshore wind power project requires 7-10 years to complete stages including:
- Survey and wind measurement
- Geological research
- Feasibility assessment
- Environmental impact assessment
- Design and component manufacturing
- Construction and installation
With the target of 7 GW by 2030 (only 7 years remaining), starting immediately is urgent.
2. Technical and financial requirements
Implementing offshore wind power projects requires:
- Complex and advanced technology
- Enormous financial investment
- Wind measurement costs: About 2 million USD
- Total initial survey costs: About 15 million USD/project
3. Lack of planning and legal framework
Experts emphasize the need for:
- Clear marine spatial planning
- Comprehensive environmental legal framework
- Long-term and stable policy mechanisms
- Transparent geological survey licensing processes
4. Resource waste issues
According to Dr. Du Van Toan, current policies do not grant exclusive survey rights, leading to:
- Multiple enterprises surveying the same sea area
- Waste of financial resources and time
- Lack of information-sharing mechanisms among enterprises
Solutions for Sustainable Offshore Wind Power Development
1. Comprehensive and long-term planning
Offshore wind power needs to be planned in coordination with:
- Sustainable marine economic development strategy (Resolution 36/NQ-TW)
- Renewable energy development orientation (Resolution 55/NQ-TW)
- Integrated marine spatial planning
- Other marine-oriented economic sectors
2. Stable policy framework
Learning from successful European countries’ experience:
- Strategic policy framework with a minimum 10-year vision
- Solid, transparent, and timely seabed leasing processes
- Clear project licensing mechanisms
- Specific financial and science-technology policies
3. Domestic supply chain development
For offshore wind power to become a sustainable industry:
- Develop local turbine and equipment manufacturing supply chains
- Increase local content in projects
- Reduce imports, promote economic development
- Attract and develop high-quality human resources
4. Exclusive survey rights mechanism
Dr. Du Van Toan proposes:
- Grant exclusive survey rights to enterprises
- Avoid resource waste when multiple units survey the same area
- Establish common rules for information sharing among enterprises
5. Inter-agency coordination
Management agencies need to:
- Promptly approve comprehensive development planning
- Announce priority areas for offshore wind power development
- Create market conditions
- Balance with other activities: maritime, national defense and security, marine conservation areas, fishing grounds
Economic and Environmental Benefits from Offshore Wind Power
Environmental benefits
According to the World Bank report (June 2021):
- Offshore wind power has the potential to supply 12% of Vietnam’s electricity by 2035
- Replace coal-fired power plants
- Reduce emissions by over 200 million tons of carbon
- Contribute to Vietnam’s Net Zero goals
Economic benefits
Developing offshore wind power will:
- Add at least 50 billion USD to Vietnam’s economy
- Stimulate local supply chain development
- Create thousands of high-skilled jobs
- Open export opportunities to global markets
- Reduce dependence on energy imports
Offshore wind power is not only a potential renewable energy solution but also an opportunity for Vietnam to develop a new, modern, and sustainable industry. With enormous offshore wind potential and favorable geographical location, Vietnam can completely become one of the leading countries in the region for offshore wind power.
However, to turn potential into reality, synchronized coordination is needed among the State, enterprises, and the international community in building long-term planning, stable policy frameworks, and developing domestic supply chains. As Dr. Du Van Toan emphasizes: “The energy transition needs and expected capacity recorded in the Draft Power Development Plan VIII are an important foundation to promote wind power development as a new industry, but long-term development planning and appropriate policy mechanisms are still needed.”
