China Powers Up Its Farthest Offshore Wind Farm
Published: 7.9.2025
China has taken a major leap forward in offshore wind energy with the successful grid connection of the first units from the 800 MW Dafeng offshore wind power project, located in the East China Sea.
Spearheaded by China Three Gorges Corporation (CTGC), this project marks the farthest offshore wind farm ever built in China, demonstrating the country’s growing engineering strength in large-scale renewable infrastructure.
Positioned 85.5 kilometers offshore from Yancheng City, Subsite H8-1 of the Dafeng project sets a new national benchmark in deep-sea wind farm development.
Key Highlights:
98 wind turbines
Three offshore booster stations
Total installed capacity: 800 MW
Annual energy output: 2.6 billion kWh (Enough to power approximately 1.1 million households)
To overcome unpredictable sea conditions, the construction team deployed a self-developed meteorological warning system, ensuring optimal safety windows for offshore operations.
At its peak, over 1,000 workers coordinated simultaneously across multiple vessels and platforms—an extraordinary feat of precision and project management.
Why This Matters for the Renewable Energy Industry?
This milestone comes as global attention shifts toward offshore wind energy as a viable path toward net-zero goals.
According to the National Energy Administration (NEA), China’s wind power capacity reached 521 GW by the end of 2024—including 41.27 GW of offshore capacity—with deep-sea installations like Dafeng expected to drive exponential growth in the coming years.
Offshore wind offers several advantages:
Stronger and more consistent wind resources
Lower land-use conflict
Proximity to coastal demand centers
Scalability to gigawatt-scale generation
Globally, over 71 billion kilowatts of offshore wind potential exist, mostly in deep-sea zones.
Yet less than 0.5% has been developed. China’s Dafeng project stands as a blueprint for how countries might unlock untapped potential using the latest marine technology and digital tools.
With the launch of Dafeng, China is sending a clear message to the international energy market: It is ready to lead in the next frontier of renewable energy—deep-sea wind power.
What the Dafeng Project Means for the Industry
Investors: Offshore wind becoming the more viable and cost-effective energy solution, more countries may move forward with deep-sea wind farms, inspired by China’s success.
OEMs & Suppliers: As confidence grows, we could start seeing a surge in funding for large-scale offshore projects.
Governments: Dafeng provides a proven model for scaling offshore wind efficiently and may encourage government may adopt more aggressive offshore goals using it as benchmark.
CTGC expects the Dafeng wind farm to be fully operational by December 2025, contributing meaningfully to China’s national clean energy targets.
More importantly, it sets a precedent for engineering ambition that could be replicated in Europe, Southeast Asia, and the Americas.
