IEA Wind TCP Research Tasks

The IEA Wind Technology Collaboration Programme’s (TCP) cooperative efforts continue to advance the technological development and global deployment of wind energy technology. The IEA Wind TCP is a vehicle for member countries to exchange information on the planning and execution of national large-scale wind system projects, and to undertake co-operative research and development (R&D) projects called Tasks.

Participation in a research Task is open to any organization located in Member Countries or Sponsor Members of the IEA Wind TCP. Cooperative research is carried out as research, development, and deployment projects of the IEA Wind TCP. Technical reports, fact sheets, and recommended practices are released publicly to benefit the wind energy community.
