Two cold climate wind energy reports out now

The IEA Wind Task 19 expert group has recently published two cold climate wind energy reports, which are now available for free.

Wind energy in cold climates (encompassing both low temperatures and icing climates) is expanding rapidly with an amazing 12 GW/year rate, equivalent of 4,000 large 3 MW wind turbines. This large market has some special challenges, especially regarding atmospheric icing conditions leading to ice accretion for wind turbines and low temperature effects on components. These markets are located all around the world (look at this free online icing and low temperature map for more details). Ice accretion on turbine blades may cause severe production losses, up to 20 percent of annual energy production, increase turbine mechanical loading and sound emissions from blades as well as increasing of ice throw hazards.

VTT has been coordinating an international expert group called IEA Wind Task 19 'Wind Energy in Cold Climates' since 2002, with as its mission to enable large scale deployment of cold climate wind power in a safe and economically feasible manner. The purpose of this expert group is to gather and provide information about wind energy in cold climates, including project development, operation and maintenance (O&M), health, safety and environment (HSE), operational experiences, and recent research. The current Task 19 working period is January 2016 to December 2018.

Task 19 has recently published two important documents:

  • Available technologies – report (May 2016), which summarises all key technologies available for cold climate wind energy applications, ranging from listing available icing maps to icing weather models, ice detectors, turbines equipped with ice protection system (de- and anti-icing), ice throw assessment, operation and maintenance, standards and testing. This is the quickest way to find a solution to your icing or low temperature challenge in just a few minutes.
  • Recommended practices – report (February 2017), which is basically an international pre-standard summarizing all best practices from numerous experts for development and operation of wind farms in cold climates. By reading this report, you will lower your risks and uncertainties substantially when developing or operating turbines in cold climate conditions.

Next, in 2017–2018, Task 19 will focus on among others:

  • developing international ice throw guidelines
  • development of turbine ice protection system (anti- and de-icing systems) performance evaluation guidelines
  • continue working with cold climate aspects for international standard IEC 61400-15 ed1 'Site energy yield assessment'

OWI-Lab is also a member of the IEA Task 19 research task force, an international expert group within IEA ‘RD&D Wind’, which deals with wind energy in cold climates.
