On 9 June 2026 in Hanoi, the Global Wind Energy Council (GWEC) released its Global Offshore Wind Report 2026. In 2025, 9.3 GW of new offshore wind capacity was connected worldwide, up 16% and the third-highest year on record. Global offshore capacity reached 92.5 GW by the end of 2025.
China leads for the eighth year in a row
China commissioned 6.6 GW of offshore wind in 2025, bringing its total to 48.4 GW. It has led the world in new offshore installations for eight consecutive years.
More than 50 GW under construction
More than 50 GW of offshore wind projects are now under construction worldwide. GWEC expects annual offshore installations to double in 2026, with a compound annual growth rate of about 24% from 2026 to 2030. It forecasts more than 327 GW of new offshore capacity over the next decade, taking the global total to 420 GW by 2035, when annual additions are expected to exceed 50 GW.
What it means for the supply chain
Offshore turbines are larger and operate in harsh conditions, which raises the bar for corrosion protection, welding and dimensional accuracy in towers, monopiles and internal structural parts. A wave of offshore construction will also lift demand for these components.
