The programme of the examination is as follows:

  • 08:30-09:00 DTU staff available for last minute installations
  • 09:00-12:00 Case study (individual)
  • 12:00-13:00 Lunch
  • 13:00-          Individual examinations


All participants will carry out a complete WAsP study; all the way from the meteorological data and digital maps to the annual energy production of a wind farm. The case study will be similar to that on the third day of a standard WAsP course. A few typical pitfalls here and there in the available information have been put in and the participant is required to identify and correct these.


In the afternoon the participants will individually present their WAsP study from the morning and then one question will be drawn from around 10 which has to be answered. The questions can be found here. There will also be a brief question concerning roughness estimation from a photograph and finally one simple question having to do with the wind atlas methodology (like: what happens to the WAsP production estimate if you – after your analysis – are told that the met. station was actually situated in a valley. Does it go up or down?).

About one hour per participant has been set aside for this part. This means of course that participants must be prepared to wait until it is their turn. Please note, that we cannot guarantee a time where we finish, so participants are advised to either book a plane late in the evening or the day after.

The grading

Based on the case study and the answers to the questions a pass/fail grade will be given by the board of examiners (consisting of at least two members of the WAsP team).

The level required is described in detail in the level requirement page.

Please also note that this is an examination and that there is no guarantee that you will pass. The level is such that it is not enough just to have participated in the WAsP course; Practical experience is also required!


You need to be a registered WAsP user in order to participate in the certification examination. The level required to pass the examination is described in detail in the level requirement page.

What to bring

Bring your own computer with the newest version of WAsP, the Map Editor, the Climate Analyst and the Turbine Editor installed and ready to run. Please note, that to run the map editor you will need at least 50 MB of RAM. A mouse is strongly recommended since digital map inspection and editing is part of the case study. Except for emergency situations, no time has been set aside for installing the software. There are no limitations to the other software installed on your PC, as long as your PC is not connected to the outside world. We recommend that you are familiar with at least one text editor (Notepad, WordPad, etc.) on your PC. Please also bring a converter plug to Danish power outlets, if the certification takes place at DTU Risø Campus.

Lunch and refreshments

Lunch will be served after the case study. Coffee, tea and soft drinks will be served during the examination.
