changes in Global Wind Organisation (GWO) trainings standard
Author: Ewelina Frank

A third version of GWO standard for Basic Technical Training was released on May 31, 2017. In this article, we have presented the most important changes introduced in that document.

  1. First of all, the name of a whole package has been changed – now it is Basic Technical Training (BTT). It still consists of three modules: electrical, hydraulic and mechanical, however, the program has been limited, which, consequently, shortened the duration of the training from 7 to 4 days. A detailed program of Basic Technical Training is available at
  2. As before, each module will end with an exam and (this is another change) the introduction to WINDA system. Therefore, you can do each module separately. However, there is a probability that only a complete training will be considered as as equivalent of so-called manufacturer’s levels.
  3. Successful completion of a training depends on tests at the end of each module – that part does not change much except that the new stanard specifies the test requirements. It cannot consist of less than 30 questions, about one minute per question. During the test there will be possibility to use few scripts and notes prepared by Training Provider.
  4. BTT is aimed at people who start their work on the wind turbines. The program of each module is arranged in a way to teach the basic principles of safe work within the most important electrical, mechanical and hydraulic systems. Basic Technical Training certificates are valid for an indefinite period of time. Companies affiliated to the Global Wind Organization will require valid BTT certificates from technicians working on their turbines since March 31, 2018

Windhunter Academy has been offering this training since October 2016. We have adapted our programs to new guidelines and we have been offering them since mid-June according to new guidelines.


The new version of Global Wind Organisation (GWO) standard gives employer the opportunity to recognize the competence of his employees without the need of sending them to  BTT, but that will be the topic for the next article…
