Analysis of China’s Wind Turbine Yarn Industry: Larger Blades to Drive Market Demand, with Limited S

2025-12-18

Overview of the Future Development Prospects and Market Demand in the Wind Turbine Yarn (Wind Energy Glass Fiber Yarn) Industry

1. Proportion of Wind Turbine Yarn in Glass Fiber Reinforced Yarns

  • Market Share: According to statistics from the China Fiberglass Industry Association, wind turbine yarn accounted for approximately 20% of all glass fiber reinforced yarns in China in 2023.
  • Application: Wind turbine yarn is a specialized electronic-grade glass fiber yarn used primarily in wind turbine blades. It can be processed into woven fabrics or pultruded sheets and used in combination with resins.

2. Impact of Larger Wind Turbines and Blades on Demand for Wind Turbine Yarn

  • Trend Towards Larger Turbines: There has been a trend towards larger onshore and offshore wind turbines in recent years, leading to an increase in the rotor diameters of wind turbine blades. This trend also involves continuous iteration and updates in blade design, structure, and materials.
  • Efficiency Gains: Technically, larger wind turbine blades increase the swept area, allowing for more efficient capture of wind energy and improving the overall efficiency of wind turbine units while reducing the cost per kilowatt-hour (kWh) of wind power.
  • Demand Forecast: The demand for high-performance wind turbine yarn is expected to grow by 33% by 2025 due to the increasing size of wind turbines and their blades. Each gigawatt (GW) of wind turbine capacity requires approximately 10,000 tons of glass fiber, meaning that 115 GW of installed wind turbine capacity corresponds to about 1.15 million tons of glass fiber.

3. Competitive Landscape and New Capacity in the Wind Turbine Yarn Industry

  • Concentrated Market: The competitive landscape in the Chinese wind turbine yarn industry is relatively concentrated, with major players like Jushi Group, Taishan Fiberglass (a subsidiary of Sinoma Science & Technology), and International Composite Materials accounting for around 90% of the national production capacity.
  • Barriers to Entry: The rapid iteration and higher production and certification barriers associated with wind turbine yarn mean that new entrants face significant challenges. Projects recently commissioned by Changhai Shares and Taishan Fiberglass involve alkali-free coarse yarns, which differ from wind turbine yarns. New entrants like Xiehe New Energy and Orient Hope, focusing on high-modulus and high-strength fiberglass, are expected to have limited short-term impact on supply.
