Topical Expert Meetings

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 are 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 in the public online library. It is the responsibility of the participants to distribute the information generated through the Task to the research centers, universities, manufacturers, promoters, and all the institutions participating in the development of the wind energy sector in their countries.

IEA Wind TEM#109 – Grand Challenges in Wind Energy Science

Paul Veers and Katherines Dykes – main facilitators of the TEM – recap the Grand Challenges event that gathered around a hundred of the greatest minds in #windenergy technology from across the globe. The focus was on interdisciplinary collaboration to create a more holistic approach to the design and deployment of wind farms, with breakout sessions coupling e.g. social scientists with wind turbine designers, atmospheric sciences with environmental scientists, and so on.

Latest TEMs

TEM #110


Wind Energy Instrumentation Development

TEM#110 was held in person in Broomfield, Colorado USA, on November 2, 2023, in conjunction with the NAWEA/WindTech 2023 Conference at the Omni Interlocken Hotel, and convened by Tommy Herges and David Maniaci from Sandia National Laboratories, and Nicholas Hamilton and Patrick Moriarty from the National Renewable Energy Laboratory. 30 experts from 7 countries gathered to discuss instrumentation gaps, opportunities challenges and barriers in breakout groups and in plenary sessions. As an outcome, the proceedings of the meeting will be published, including a Roadmap for instrumentation development.

TEM #106


Hydrogen for 100% Renewable Energy Systems

TEM#106 was hosted by the National Renewable Energy Laboratory (NREL) and held at the University of Colorado, Boulder (US) and online, on September 6 -7, 2023. The aim of this TEM, which gathered over 80 participants, was to lay the groundwork for a cross-cutting collaboration between the wind, PV and hydrogen TCPs managed by IEA Secretariat. As an outcome, the proceedings of the meeting will be published, including the identification of future R&D needs and a potential new joint or linked task between the Hydrogen, PVPS, and Wind TCPs.

TEM #105


Harmonised LCA for Wind Energy

TEM#105 was hosted by the Zurich University of Applied Sciences (ZHAW) and took place in Wädenswil, Switzerland, on September 21-22, 2023. During 2 days, 30 international experts on the environmental profile of wind energy initiated a discussion on the key considerations for a guiding framework on life cycle assessment of wind energy. The discussion centered around the topic of quantitative life cycle assessment of wind energy and guidance on inventory modelling and data, impact assessment, interpretation, reporting, and communication of LCA results. A wind LCA factsheet, which will represent the main outcome of this meeting, is currently being finalized, and the majority of participating experts agreed that a dedicated IEA task would be the way forward.
