About TEMs

The IEA Wind Task 11 gathers experts to present the latest results on narrow topics and discuss solutions in a small group setting.

The Topical Expert Meetings (TEM) organized in the frame of Task 11 play an important role since they aim to begin the conversation about new technical and scientific developments and information needs. Task 11 is also an important catalyst for starting new research tasks within IEA Wind. It is frequent that after a TEM, an ad hoc working group will write a proposal to begin a new research task. Most research activities of IEA Wind began with a TEM.

Four TEMs per year are organized under Task 11. The Operating Agent (OA) solicits topics for future meetings that are presented and validated during one of the biannual ExCo meetings. A host country and organization is identified and an expert writes an introductory note that is sent out with the meeting invitation. The invitation process is coordinated by Task 11 OA. Task 11 participants as well as the host select institutions and experts that will receive an invitation to the meeting. All attendees are expected to give presentations that contribute to the meetings.

The OA moderates the meeting and assembles the proceedings. During one year, the proceedings are only available for Task 11 participating countries. After that, they are posted on the public online library. It is responsibility of the participants to distribute the information generated through the Task to the research centers, universities, manufactures, promoters, and all the institutions participating in the development of the wind energy sector in their countries.

Template documents for proposing a TEM topic and realising a TEM are available in the Task 11 Library (insert link).

TEM #102


Airborne Wind Energy: Challenges and Opportunities

TEM#102, hosted by Airborne WInd Europe, Kyushu University, NCSU, NREL and WindForS, will take place on September 23 & 24, 2020.  Experts from the whole world will gather online to discuss  the challenges and opportunities linked to this disruptive technology. and identify the research priorities to be addressed through international collaboration within a new IEA Wind Task, accelerating the pace of technology development and deployment.

Latest TEMs

TEM #101


Hybrid Power Plants

This TEM, hosted by DTU & NREL, brought together experts from the wind, solar and storage communities to discuss the state of the art, research needs and future opportunities related to hybrid power plants. Cross-TCP collaboration and technology development will be fostered in the frame of a new IEA Wind Task.

TEM #99

JULY 2020

Floating Offshore Wind Arrays

This first-ever online TEM hosted by IFPEN, MaREI (UCC), NREL & Principle Power, gathered a total of over 100 experts from 18 different countries in a successful 3-day online event. They discussed the challenges linked to array-scale deployment of floating wind turbines, resulting in a new IEA WInd Task proposal tackling the challenges unique to the topic.

TEM #98


Erosion of Wind Turbine Blades

This TEM took place in Roskilde, Denmark and gathered 29 experts from 12 different countries to discuss the key factors and research needs regarding the erosion of leading edge wind turbine blades. The topic is highly multidisciplinary and there are plenty of opportunities for international collaboration in the frame of an IEA Wind task.
