IEA Wind Task 19 considers wind turbine performance testing in icing climates as a key
element to mitigate risks when developing wind farms in cold climates and for accelerating
wind turbine technology improvements in cold climate conditions. The first edition of the
Performance Warranty guidelines for wind turbines in icing climates was published in May
2018. The aim of this second edition is to present and further detail the most promising
available options on how wind turbines with icing climate adaptations can be warranted and
tested with affordable and reasonably accurate test methods.
