Offshore wind installations are becoming an increasingly important component of the global renewable energy sector, supported by stronger and more consistent wind conditions available at offshore locations compared with land-based sites.
- According to the Global Wind Energy Council, 2026, approximately 9.3 GW of new offshore wind capacity was connected in 2025, bringing cumulative global capacity to around 92.5 GW. This operational capacity could generate electricity equivalent to the annual consumption of nearly 102 million households, demonstrating the sector’s growing role in energy security and low-carbon power generation.
- Government renewable energy targets continue to support the expansion of offshore wind installations. According to the European Commission, 2024, European Union member states set combined offshore renewable energy ambitions of 86–89 GW by 2030, 259–261 GW by 2040, and 356–366 GW by 2050. These targets are encouraging coordinated maritime planning, cross-border electricity networks, and offshore energy hubs while providing long-term visibility for turbine manufacturers, cable suppliers, engineering companies, utilities, and institutional investors.
- According to the UK Government, 2025, approximately GBP 900 million was allocated for fixed-bottom offshore wind and GBP 180 million for floating offshore wind under the seventh Contracts for Difference allocation round. The government also set an administrative strike price of GBP 113 per MWh for conventional offshore wind. These measures improve revenue certainty, although developers continue to face challenges from high financing costs, construction inflation, and supply-chain pressures.
The medium-term outlook for offshore wind remains positive, although growth is expected to differ across regions. According to the International Energy Agency, 2025, approximately 140 GW of additional offshore wind capacity could be installed between 2025 and 2030. Annual installations are projected to rise from 9.2 GW in 2024 to more than 37 GW by 2030. However, the agency reduced its offshore wind forecast by 27% due to policy uncertainty, project cancellations, higher equipment costs, and weak auction participation. Faster permitting processes and timely grid connections will therefore remain critical to supporting future project development.
- According to the U.S. Department of Energy, 2025, the Floating Offshore Wind Shot aims to reduce floating wind energy costs by more than 70%, reaching USD 45 per MWh by 2035, while supporting the deployment of 15 GW of floating offshore wind capacity.
