China Wind Turbine Rotor Blade Market Size & Share Analysis - Growth Trends And Forecast (2025 - 2030)

China Wind Turbine Rotor Blade Market Trends and Insights

Ambitious 2030 Wind-Power Capacity Targets

China plans to hit 400 GW of cumulative wind by 2030, with 140 GW slated for 2025 alone. This policy certainty drives the long-term procurement of ever-larger rotors, 58.6% of which now exceed 180 m in diameter.^{[1]Global Wind Energy Council, “Global Wind Report 2025,” gwec.net} Grid-parity objectives force OEMs to optimize blade aerodynamics for diverse inland and coastal conditions. Consistent government backing sustains capital inflows into new blade factories, sparking technology upgrades that keep the Chinese wind turbine rotor blade market on a steep growth curve.

Cost Decline in > 80 m Carbon-Glass Hybrid Blades

Hybrid composites reduce blade weight by 38% and costs by 14% compared to glass-only designs, while maintaining stiffness.^{[2]Advanced Materials Research, “Hybrid Composite Blades for Offshore Wind,” advancedmaterials.org} Automated fiber placement and thermoplastic processing now enable serial manufacture, anchoring China’s leadership in blades exceeding 80 m in length for offshore use. Local suppliers of polyurethane resin systems are strengthening hybrid adoption, pushing the China wind turbine rotor blade market toward lightweight, high-performance solutions suited for 16 MW-class turbines.

Rapid Offshore Wind Build-Out Along Coastal Provinces

Jiangsu already hosts 55% of national offshore capacity, and the 800 MW Dafeng deep-sea array became China’s farthest offshore project in 2025. Coastal incentives and reduced transmission losses encourage the use of larger rotors to harness stable marine winds, thereby increasing blade demand. Government estimates indicate that offshore resources could yield over 1,000 TWh annually, accounting for a third of coastal electricity needs. These factors collectively propel the China wind turbine rotor blade market deeper into high-margin offshore segments.

Accelerating Replacement of 2010-Era Onshore Turbines

Early-generation ≤ 2 MW machines with ≤ 45 m blades are financially outclassed by today’s > 5 MW, 150 m-rotor units. Operators leverage existing grid links to repower, multiplying site output without new land acquisitions. Warranty expirations and high O&M costs heighten urgency, channeling orders into modern blades and boosting near-term revenue in the China wind turbine rotor blade market.

Volatile Epoxy & PET Foam Prices Squeezing Margins

Shift from scarce balsa to PET foam magnifies exposure to petrochemical swings; resin spikes already compress OEM margins by up to 3 percentage points.^{[3]United States International Trade Commission, “PET Foam Supply Chain Trends,” usitc.gov} Currency shifts and import tariffs complicate budgeting, compelling supply-chain diversification and trials of bioplastics, also known as bio-resins. Price pass-through is limited amid cut-throat turbine bidding, keeping profitability pressure high across the Chinese wind turbine rotor blade market.

Grid Curtailment Risk in Northern China Wind Bases

Curtailment once topped 47% in Gansu, eroding ROI for new blades despite recent UHV line progress^{.[4]Energy Policy Journal, “Curtailment and Market Reforms in Northwest China,” energypolicy-journal.org} Spot-market reforms improved utilization by 26.8% in Northwest China; however, seasonal oversupply still poses a threat to cash flows. Storage projects and cross-provincial trading are crucial for locking in demand and safeguarding growth in the Chinese wind turbine rotor blade market.

Segment Analysis

By Location of Deployment: Onshore Repowering Steers Near-Term Volume

Onshore blades contribute 92.5% of 2024 installations and are projected to log a 13.2% CAGR to 2030, driven by large-scale repowering that rapidly expands the China wind turbine rotor blade market size for this segment. Fleet owners in Inner Mongolia and Xinjiang swap out sub-2 MW units for modern 5 MW designs that increase site yields by more than 70% 

Latest province-level auctions include strict LCOE caps, prompting OEMs to opt for longer rotors to maximize megawatt-hours within fixed tariffs. Enhanced aerodynamics and hybrid materials keep nacelle mass in check, ensuring logistics feasibility across rugged inland transport routes. The result is a virtuous cycle of capacity factor gains and declining costs that entrenches onshore leadership in the Chinese wind turbine rotor blade market.

Offshore arrays, though smaller today, represent the fastest-growing slice, adding more than 10 GW annually after 2025. Jiangsu’s deep-sea sites pioneered 240-m rotor trials in 2025, signalling future procurement of extra-long, splash-zone-resistant blades. Floating foundations under test in Fujian could unlock Southern deep-water zones, expanding geographical diversity and boosting the overall China wind turbine rotor blade market.

By Blade Material: Hybrids Challenge Carbon Fiber Dominance

Carbon fiber’s 51% share stems from its stiffness-to-weight edge, especially for > 10 MW offshore machines. Yet, hybrids will see a 13.6% CAGR to 2030 and could overtake carbon by volume before 2032, reshaping the China wind turbine rotor blade market share landscape.

Producers blend carbon unis with glass fabrics, lowering cost while retaining critical bending stiffness. Thermoplastic resins make large-part recycling feasible, aligning with China’s 2030 circular-economy standards. Hybrids thus bridge the cost and sustainability gap, widening the addressable demand and anchoring market expansion.

By Blade Length: Above 75 m Category Sets the Pace

The 61–75 m class holds 47.5% share, but blades above 75 m are advancing at 14.5% CAGR, the strongest of any segment. This length class anchors 16 MW offshore turbines and next-generation 8 MW onshore units, which drive down LCOE by capturing steadier, high-altitude winds.

Logistics constraints on road transport are driving the development of modular blade concepts, which ease last-mile delivery to remote mountain sites while sustaining the China wind turbine rotor blade market for ultra-long products. Specialized rail and river-barge corridors further enhance growth prospects for the category, exceeding 75 m.

By Manufacturing Process: Pre-Preg Gains Traction Amid Automation

Vacuum infusion’s 58.3% share reflects mature workflows and moderate capex. Pre-preg, growing at 13.1% annually, couples automated layup with low void content, which is crucial for fatigue life in duty cycles exceeding 20 years offshore.

Pultrusion of spar caps and shear webs cuts resin wastage and supports serial production, enhancing throughput in plants targeting 6,000 blade sets per year. Integrated digital twins detect defects in situ, reducing rework and supporting cost competitiveness throughout the Chinese wind turbine rotor blade industry.

Geography Analysis

The Three-North region still accounts for over 60% of cumulative installations and remains central to the China wind turbine rotor blade market; however, curtailment and harsher climates mean growth rates trail the national average. Ultra-high-altitude sites in Tibet went online at 4,650 m in 2024 and require custom low-temperature resin systems that widen technological niches.

Coastal provinces, particularly Jiangsu, dominate offshore capacity and are home to dense manufacturing clusters. Proximity between plants and ports reduces transport risk for blades exceeding 100 m. Guangdong and Zhejiang augment demand with generous feed-in premiums and streamlined approvals, underpinning double-digit regional CAGR.

Central and Eastern provinces, such as Shandong, strike a balance between inland and coastal advantages. Mature rail links feed export shipments, making Shandong a pivotal hub for international blade orders that broaden the addressable China wind turbine rotor blade market beyond domestic needs. Improved inter-provincial power trading further incentivizes developers to site new projects where grid stability and load proximity coincide.
