IEA Wind Task 19: Wind Energy in Cold Climates (working period 2016 - 2018)

IEA Wind Task 19 deals with the challenges of the utilisation of wind energy in Cold Climates (i.e. under icing-conditions) and offers through global networking and mutual exchange of experience, the possibility of collecting and generating additional know-how. Aim of the subtask was to share experiences with international partners and standardising of icefall risk assessments. In addition, an evaluation report on the functionality of the new Vestas rotor blade heating system was published.

Short Description

The Experts of IEA Wind Task 19 have been dealing with the manifold challenges of wind power under icing conditions for more than 15 years. The primary aim of this international research cooperation is to collect and generate new knowledge through mutual exchange of experience and global networking. This is achieved through biannual task workshops, where national research projects are presented and discussed.

During the last term (2016 to 2018) Energiewerkstatt worked on the following two research topics:

  • Energiewerkstatt led a subtask that dealt with the standardization of icefall risk assessments. As a result, an official recommendation of Task 19 was published in 2018, selecting and defining the essential methodology and input parameters for ice-throw/icefall risk assessments.
  • Furthermore, Energiewerkstatt evaluated the performance and functionality of the Vestas rotor blade heating system.

Parallel to the work on those research projects, guidelines with best practice examples and recommendations for the realization of wind energy projects under icing conditions were published under the umbrella of IEA Wind Task 19. These documents contain recommendations for internationally valid definitions and classification systems and serve as inputs for norms and standards.

In order to ensure a smooth knowledge transfer of international expertise to Austria, Energiewerkstatt served as a national interface for the IEA activities. In co-operation with the Austrian Wind Energy Association international know-how was disseminated in Austria.

In addition, basic data on wind energy utilisation and research projects in Austria was provided for the annual reports of IEA, with the goal of a successful international positioning of the Austrian research activities and deployment trends.
