Offshore Wind: Top 10 Companies in China in 2025

Beyond the Horizon: The Unstoppable Rise of China’s Ultra-Large Offshore Wind Turbines

Imagine a single spinning blade longer than a football field, sweeping through the sky miles from shore. Now imagine three of them, mounted on a tower that rivals the Eiffel Tower in height, generating enough clean electricity to power a small town. This isn’t a scene from a futuristic film; it’s the reality being built today off the coast of China. Fueled by ambitious national policy and fierce corporate competition, Chinese firms are locked in a technological “arms race” to create ever-larger, more powerful offshore wind turbines. This relentless escalation is not just redefining the limits of engineering; it’s positioning China to dominate the next chapter of the global energy transition, one colossal turbine at a time.

From Blueprints to Blue Horizons: The Expanding Application Ecosystem

The diversity of these projects signals that industry adoption is moving beyond simply building larger turbines for standard, fixed-bottom wind farms. A crucial pattern is the strategic push into deep-water floating wind. Projects by CNOOC (a 150 MW demonstration) and technology unveilings from China Huaneng Group and Mingyang (with its ambitious 50 MW twin-head design) show a concerted effort to unlock wind resources in deeper waters, where fixed foundations are not feasible. This represents a significant expansion of the addressable market. Furthermore, the role of specialized firms like Eastern International Ltd., which handles the complex logistics of transporting 110-meter blades, highlights the maturation of a supportive ecosystem. The adoption of giga-turbines is therefore not a monolithic trend; it’s creating a vertically integrated supply chain, from turbine design to specialized maritime logistics, all scaling in tandem.

The East Is Green: How China Forged a Global Offshore Wind Nexus

The geographic concentration of these advancements is impossible to ignore: they are all happening in China. This is not a coincidence but the direct result of a powerful, state-driven industrial strategy. The Chinese government, through policies like the Beijing Declaration 2.0, provides a massive and predictable domestic market by mandating huge annual installations (at least 15 GW of offshore wind annually). This guaranteed demand de-risks investment and allows state-owned developers like China Three Gorges Corporation and China Huaneng Group to finance and build giga-scale projects. These developers, in turn, provide a captive market for turbine OEMs like Goldwind, Mingyang, and DEC, fueling their R&D and manufacturing scale-up. This closed-loop system creates an unparalleled competitive advantage. Now, this nexus is preparing to go global. Mingyang’s announcement of a potential $2 billion factory in Scotland is a clear signal that the strategy is shifting from domestic consolidation to aggressive international expansion, leveraging the scale and technology perfected at home.

The Race to the Top: Escalation from Prototype to Powerhouse

These installations reveal a technology in a state of hyper-acceleration. The market is not just mature; it’s in an active “arms race.” We can see a clear progression. First, you have the commercial-scale turbines like SANY’s 13.6 MW model securing its first major orders, representing the current market-ready technology. Simultaneously, companies are pushing the immediate boundary with record-breaking prototypes, such as DEC’s successful installation of a 26 MW turbine and Goldwind’s 20 MW machine. Finally, you have forward-looking R&D setting the stage for the next leap, exemplified by Mingyang’s conceptual plan for a staggering 50 MW floating turbine. This three-tiered progression—commercial deployment, prototype testing, and conceptual design—is happening concurrently and at a blistering pace. It shows that the technology is mature enough for mass deployment while still having enormous headroom for innovation, driven by intense domestic competition to be the first to the next milestone.

Winds of Change: Charting the Future of Global Energy

The message from these milestones is unequivocal: ultra-large offshore wind turbines, engineered and scaled in China, are set to become a defining force in the global energy landscape. The future is not just about incremental increases in turbine size; it’s about the export of China’s entire vertically integrated model—combining state-backed project development, cost-competitive manufacturing, and cutting-edge technology. The relentless push from 13.6 MW commercial units to 26 MW prototypes and 50 MW concepts within a single year signals an industry compressing a decade of Western R&D cycles into a few years. As companies like Goldwind and Mingyang look to deploy over 200 GW internationally by 2034, Western manufacturers will face unprecedented competition not just on price, but on technological prowess and speed. The giga-turbines rising in the East are casting a long shadow, heralding a fundamental shift in the world’s clean energy supply chain.
