Recommended Practices

Recommended Practices

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 projects called Tasks or Annexes. As a final result of research carried out in the IEA Wind TCP Tasks, Recommended Practices, Best Practices, or Expert Group Reports may be issued. A Recommended Practices document includes actions and procedures recommended by the experts involved in the research project. Use of these documents is completely voluntary. However, these documents are often adopted in part or in total by other standards-making bodies.

Recommended Practice 8: Glossary of Terms
Due to the widening appeal of wind energy it was considered that a Glossary of Terms, expressed in simple language, would serve to introduce consistency into future publications of the IEA as well as be of use to those with an interest in wind energy such as planning authorities, manufacturers and users of wind turbines.

Recommended Practice 6: Structural Safety Review of (Draft) Standards/Codes of Practice
The aim of this document is to compare the (draft) standards and codes and to comment on their similarities and their differences. The conclusions drawn from this is intended to be of help for national standards committees (both present and future) in formulating a consistent set of safety standards as well as to stimulate international standardization.

Recommended Practices for Wind Turbine Testing and Evaluation, 2nd Edition
This document describes the recommended practices for testing and reporting power performance characteristics of a single Wind Turbine (WT). It provides a standard methodology, exclusively for comparing the energy production characteristics of WTs available in the market.

About Recommended Practices

These documents have been developed and reviewed by experts in the specialized area they address. They have been reviewed and approved by participants in the research Task, and they have been reviewed and approved by the IEA Wind Executive Committee as guidelines useful in the development and deployment of wind energy systems. Use of these documents is completely voluntary. However, these documents are often adopted in part or in total by other standards-making bodies.
