Vietnam has significant offshore wind resources, supported by favorable geology, a long coastline of more than 3,260 km, over 1 million square kilometers of sea area, a shallow continental shelf and year-round winds. The Global Wind Energy Council (GWEC) estimates Vietnam’s offshore wind potential at about 600 GW, positioning the country as one of Asia’s most attractive clean-energy targets.
“Vietnam’s offshore wind potential is very large—about 600 GW,” said Bui Vinh Thang, GWEC Country Director for Vietnam. Despite this scale, Vietnam is currently exploiting only about 1% of its offshore wind potential, equivalent to roughly 6 GW.
With the right investment and development, GWEC says Vietnam could rise to the top five offshore wind markets in the Asia-Pacific region.
The GWEC Global Offshore Wind Report 2026 projects that in the 2031–2035 period, Vietnam could become the fifth-largest offshore wind market in APAC if it installs 7 GW of new offshore wind capacity, aligned with targets in the revised VIII Power Plan.
The projections were discussed during the APAC Wind Energy Summit 2026 in Hanoi on June 9–11, 2026, hosted by GWEC and RE+ Events under the theme “Wind power creates prosperity in APAC: Building an electricity-based economy by expanding offshore wind and supply chains.”
Offshore wind is also expanding globally. Global Market Insights Inc. estimates the market will rise from $109 billion in 2026 to $307.5 billion by 2035, representing a compound annual growth rate (CAGR) of 12.2% from 2026 to 2035.
In a scenario where Vietnam fully develops 600 GW of offshore wind, the sector could generate between 2,100 and 2,400 TWh per year. This estimate is based on an offshore wind capacity factor of about 40–45%, which is higher than onshore wind due to more stable offshore wind conditions.
GWEC links this potential to Vietnam’s electricity demand forecasts under the VIII Power Plan: total electricity sales are projected at about 500–558 TWh by 2030 and 1,238–1,375 TWh by 2050.
On that basis, fully exploited offshore wind capacity of 600 GW could supply roughly 1.5 to 2 times Vietnam’s total electricity demand by 2050. The article says this would be enough to support domestic supply for all 100 million people, enable clean electricity exports to Singapore, Thailand and Malaysia via submarine cables, and support green hydrogen and green ammonia production.
Vietnam still relies on imported coal and hydropower, both facing increasing pressure from climate change. With two-digit electricity demand growth, the article argues that wind power would play a crucial role in the future energy mix. It notes that offshore wind offers more stable generation than solar and is less weather-dependent than hydropower.
On climate, the article states that developing 600 GW of offshore wind would eliminate hundreds of millions of tons of CO2 per year, supporting Vietnam’s Net Zero commitment by 2050 announced at COP26.
