Wind Turbine Blades Being Manufactured in İzmir

Wind Turbine Blades Manufactured in Izmir Izmir is the city with the highest installed wind energy capacity in Turkey and has become a production hub for wind turbine blades, which play a crucial role in wind energy generation. With global climate change, the importance of renewable and clean energy has increased. At the same time, the energy crisis that has occurred has raised the value of domestic energy sources. For these reasons, interest in wind energy and consequently wind turbines has been increasing in recent years in our country. The share of wind energy in Turkey's installed electricity capacity has approached 11 percent thanks to investments, and Turkey possesses a capacity exceeding 11,400 megawatts in wind energy. This energy is supplied from power plants in 47 provinces.

Approximately 4,000 Blades Produced Annually

With 1,754.9 megawatts, Izmir has the highest installed wind energy capacity in the country and stands out in equipment manufacturing in this field. There are 4 blade production facilities within 3 companies in Izmir, and these facilities produce approximately 4,000 blades annually. Blade production is supported by turnover exceeding USD 700 million and exports surpassing USD 500 million.

Composites Form the Main Material of Blades

Composites constitute the main materials in blade production, and these blades are created through intensive labor. Blades are primarily composed of fiberglass, carbon fiber and resin. In production, wind turbine blades are manufactured in two shells, and the molds that form the shells vary according to blade length. For this reason, the amount of fabric used for the shells also varies. After the shell phase, the surface preparation stage of the turbines begins. Following sandpapering and connection operations for tower mounting in the relevant section, certain technical processes are carried out. After the blade is painted, it becomes ready for shipment.

Assured to Operate at Speeds Reaching 300 Kilometers per Hour

The time for a blade to exit the mold is 24 hours, while completion of all operations can take 1-2 weeks. Great care is taken to ensure no errors occur during the manufacture of wind turbine blades, and these blades are expected to last 20-30 years after installation. These blades are assured to operate at speeds reaching 300 kilometers per hour. Source
