Why Test Turbine Blades?

Wind turbine blade testing is a critical factor in maintaining high levels of reliability and evaluating the latest technological developments in airfoils and materials. Blade testing is required as part of turbine certification to meet international design standards including IEC, GL and DNV. Meeting international standards allows developers to mitigate the technical and financial risk of deploying mass-produced wind turbines.

WTTC Experience

Since opening in 2011, Wind Technology Testing Center (WTTC) has run 35 distinct blade testing programs entailing hundreds of individual blade tests. WTTC is an ISO/IEC 17025 accredited Laboratory and a RETL (Renewable Energy Testing Laboratory) per the IECRE rules and procedures to test wind turbine blades. The WTTC’s technical team includes experienced blade test engineers and technicians. WTTC is innovating and constantly improving testing methods to better represent field operations in the lab and to improve testing efficiency for wind industry partners.
