Upon completion of the (GWO) Basic Technical Training (BTT), you will be aware of the hazards involved in working on hydraulic, mechanical and electrical systems in a wind turbine environment and how to control these hazards. You will be ready to work in the wind energy industry upon completion.


The GWO – Basic Technical Training (BTT) consists of the following three Modules:

  • Mechanical (BTTM)
  • Electrical (BTTE)
  • Hydraulics (BTTH)

The Basic Technical Training modules are aimed at candidates who have no previous experience with hydraulic, mechanical or electrical systems, but can also be used to retrain candidates who have some knowledge, but not of their application in wind turbines.


This Basic Technical Training (BTT) course should enable participants to perform basic hydraulic, mechanical and electrical tasks under the supervision of an experienced technician.

This course does not make participants a trained person to perform hydraulic, mechanical or electrical work without supervision.
