More than 9 GW of new offshore wind capacity was grid-connected worldwide in 2025, bringing total installed offshore wind capacity to 92.5 GW. The global offshore wind market expanded at an average annual rate of 10% over the past decade. Offshore wind now accounts for 7.1% of total global installed wind capacity.
China remained the largest offshore wind market for the eighth consecutive year, commissioning 6.6 GW in 2025. Europe added nearly 2 GW, with installations in the United Kingdom (1.0 GW), Germany (0.5 GW) and France (0.4 GW). Outside mainland China, new offshore wind capacity was also commissioned in Taiwan and South Korea.
China accounted for 52% of global offshore wind capacity, followed by the United Kingdom, Germany, the Netherlands and Taiwan. European offshore wind installations surpassed 38 GW, representing 42% of global offshore wind capacity.
The average turbine rating installed in the offshore wind sector during 2025 was 10.3 MW.
A total of 11.4 GW of offshore wind capacity was awarded through auctions in 2025, equivalent to around one-fifth of the record volume awarded in 2024. The report also identified approximately 25 GW of consented offshore wind projects outside China that are considered ready to build but are awaiting final investment decisions, grid connections, auction results or support mechanisms.
Global offshore wind capacity is forecast to grow at a compound annual rate of 24% between 2026 and 2030. More than 327 GW of new offshore wind capacity is expected to be installed over the next decade, increasing total global offshore wind capacity to 420 GW by the end of 2035.
The figures are published in the 2026 Global Offshore Wind Report by the Global Wind Energy Council.
