Global Offshore Wind Capacity Set to Grow to 420 GW by End of 2035, Gwec Report Says

Why It Matters

The surge in offshore wind capacity accelerates the global clean‑energy transition and creates a massive pipeline of investment opportunities, while highlighting persistent grid‑connection and permitting bottlenecks that could curb momentum.

Key Takeaways

• Global offshore wind to hit 420 GW by 2035
• 92 GW installed by 2025 powers ~100 million homes
• China holds 52% of offshore wind market share
• Grid‑connection delays remain major barrier to project rollout

Pulse Analysis

The Gwec’s latest outlook underscores an unprecedented expansion of offshore wind, positioning the sector as a cornerstone of the decarbonisation agenda. With 420 GW slated for 2035, the industry will dwarf current onshore wind installations and supply clean electricity to hundreds of millions of households. This growth trajectory is driven by falling turbine costs, supportive policy frameworks, and the strategic advantage of offshore sites that capture stronger, more consistent winds.

China’s dominance, now accounting for over half of global offshore capacity, reflects aggressive national targets and massive state‑backed financing. Europe, led by Germany, the Netherlands, and the UK, continues to push ahead with ambitious auction schemes, while Taiwan leverages its deep‑water coastline to attract foreign developers. The convergence of these regional pushes is creating a robust supply chain, from blade manufacturers in Europe to port facilities in Asia, further compressing project timelines and driving down levelized costs.

Despite the optimism, the sector faces critical hurdles. Lengthy permitting processes and grid‑connection bottlenecks pose significant risk to developers and investors, as highlighted by Gwec’s deputy CEO. Addressing these challenges will require coordinated policy reforms, accelerated grid upgrades, and innovative financing structures. Stakeholders who can navigate these complexities stand to benefit from a market poised to deliver trillions of dollars in renewable infrastructure over the next decade.
