Wind Energy consultancy

We are highly specialized in Wind Energy technology and can help you solve the problems where everyone else failed (I say it because we already did this). We like challenges, and we always take the job to completion. We have a practical engineering approach to the task, with focus of economy of solutions, simplicity, safety, maintainability, reliability and quality.


  • Design of small wind turbines (up to 16 m rotor diameter): components selection and load calculation according to IEC61400-2.
  • 3D design and detailed engineering of all mechanical elements.
  • Finite elements stress analysis of mechanical components.
  • Manufacturing drawings.
  • Design of control system for stall and pitch regulated wind turbines (schematics, PLC software, custom electronic boards).
  • Consultancy on wind turbine safety, refurbishment, performance.
  • Wind turbine power performance measurements according to IEC61400-12-1 and IEC61400-12-2 standards.
  • Inspection of second hand wind turbines.
