Offshore Wind: Top 10 Projects in China in 2025

The New Great Wall: How China’s Offshore Wind Power Sector is Conquering the Seas

Introduction

Imagine building an energy source so vast it could power a country the size of Spain from the sea alone. This isn’t a futuristic fantasy; it’s the reality unfolding off the coast of China. While the world watches, China is constructing a veritable “Great Wall” of wind turbines at a scale and speed that is redefining the global energy landscape. By the end of 2024, China’s offshore wind capacity hit an astounding 41 GW—more than half the world’s total. This is not just about adding renewable capacity; it’s a calculated strategy of industrial supremacy, where giga-scale projects and relentless technological innovation are cementing China’s role as the undisputed leader in offshore wind power. The projects materializing in 2025 are not just installations; they are declarations of a new energy world order.

Industry Adoption: From Giga-Farms to Strategic Power Hubs

The diversity of these projects signals that China’s strategy goes far beyond simply generating electricity. It is about strategic integration and securing a multi-faceted energy future. We see multi-gigawatt farms like the Jiangsu Offshore Wind Projects (1.6 GW) built for raw, utility-scale power. At the same time, the Guangdong Pearl River Delta Phase IV project by CTGNE is strategically positioned to energize the Greater Bay Area, one of the world’s most critical industrial and economic hubs. This direct link between renewable generation and industrial demand showcases a sophisticated approach to decarbonization and energy security. The adoption isn’t just about size, but also about conquering new frontiers. The Yangjiang Shaba III Complex proves commercial viability in deeper waters, setting the stage for future expansion beyond the coast. This range of applications—from powering megacities to enabling deep-sea operations—implies that offshore wind is becoming a foundational pillar of China’s economic and energy policy.

Geography: Coastal Provinces as Crucibles of Wind Power

The map of China’s offshore wind dominance is written along its coastline. Provinces like Guangdong, Jiangsu, and Shandong are not just locations; they are epicenters of a state-driven industrial revolution. These regions are leading for clear, strategic reasons: they have strong, consistent winds, proximity to massive coastal population and industrial load centers, and the political mandate to meet national renewable energy targets. Guangdong, with projects like the 1.2 GW Pearl River Delta farm, leverages offshore wind to power its manufacturing might. Jiangsu is a hub for massive-scale projects developed by companies like Eastern International Ltd. Meanwhile, Fujian, with its powerful winds in the Taiwan Strait, has become a hotbed for technological breakthroughs, hosting both the Pingtan farm’s 16 MW turbines and the Fujian Offshore Turbine Test Site. This intense regional focus creates powerful ecosystems of developers, manufacturers, and port infrastructure, creating a competitive dynamic that accelerates innovation and deployment across the country.

Tech Maturity: Scaling Turbines and Conquering Deep Waters

These installations reveal a clear, three-tiered approach to technological maturity: commercializing at scale, pioneering new frontiers, and investing heavily in next-generation R&D.
First, mature, proven technology is being deployed on a massive scale. The SPIC U 1 project, with its 106 turbines of 8.5 MW capacity, demonstrates the industry’s ability to execute large, complex projects efficiently.
Second, the industry is rapidly commercializing the next wave of technology. The Pingtan Offshore Wind Farm’s deployment of Goldwind’s 16 MW turbines shows how quickly larger, more cost-effective units are moving from prototype to commercial operation. This is the engine of cost reduction.
Third, and most strategically, China is pioneering the future. The Qingzhou IV project, a relatively small 16.6 MW installation, is hugely significant as it features CRRC’s innovative ‘Ocean X’ floating wind platform. This is a critical demonstration project for unlocking the vast energy potential of deep waters where fixed-bottom turbines are not feasible. Simultaneously, the Fujian Test Site, supported by China Three Gorges Co., is pushing the absolute limits of technology by installing the world’s first 20 MW turbine, with prototypes for 26 MW and even 35 MW units already on the drawing board. This layered approach ensures dominance today while securing leadership for decades to come.

Forward-Looking Insights: State-Crafted Supremacy and the Next Frontiers

China’s offshore wind sector is a masterclass in state-orchestrated industrial supremacy. The projects of 2025 are not isolated successes but the product of a vertically integrated ecosystem designed for global leadership. The immense domestic market, protected and nurtured by state policy, allows developers like China Three Gorges and SPIC to underwrite giga-scale projects. This, in turn, provides a massive proving ground for domestic manufacturers like Goldwind and Mingyang Smart Energy, enabling them to hyper-scale innovation and drive down costs at a rate Western competitors find difficult to match.
Looking forward, two frontiers are clear: deep-water floating platforms and wind-to-hydrogen integration. With shallow waters becoming saturated, the successful demonstration of floating wind at projects like Qingzhou IV signals the start of a major push into deeper seas. This will be the next great expansion phase. Furthermore, the sheer scale of generation from projects like the planned 43.3 GW Taiwan Strait Wind Farm will necessitate energy storage solutions, positioning green hydrogen as a logical next step. China is not just building wind farms; it is building the foundation of a new energy economy and positioning itself to export this expertise and technology to the world.
