Why WindFarmer from DNV?

DNV is constantly innovating to meet its customers' changing needs. We transform ideas into services and solutions co-created with our customers.

We are committed to providing the wind industry with the most accurate prediction of future energy output. WindFarmer draws on DNV's 35 years and 340 GW of global wind farm energy production assessment experience, as well as 900 years of onshore and offshore operational data from completed projects, to continuously validate our methods and improve analysis transparency, project assurance, and project bankability.

The rapid expansion of offshore wind presents new energy assessment challenges due to larger machines, massive project scale, and flow conditions.





Yes, we offer discounted licences for researchers and for classroom teaching. 

Research licences provide fully functional software at a 50% discount. Research usage should meet all the following criteria:

  • The contracting party is an academic institution; its primary purpose is teaching and/or R&D, and it is not owned by a commercial organization
  • The work for which WindFarmer will be used is funded by government or other non-commercial entity
  • The results of the work will be published in an academic journal or conference paper
  • The sites and turbine models used are generic models available to others without undue restriction

Educational licences are offered to professors and lecturers for use by up to 50 students in a teaching environment. Please contact our sales team for more information on limitations and pricing.



WindFarmer is compatible with many file formats and its scripting capability provides a convenient way to interface with other formats, including your own in-house formats.
