Opening session: What is at stake? Volumes, market potential and possible strategies

10:00 – 10:45

The average operational lifetime of a wind farm is estimated to be of 20-25 years. In many European countries, a growing share of wind farms are over 10 years old – a proportion that can reach 60% in first-mover markets like Denmark and Germany. As wind assets come closer to the end of their operational lifetime, operators are confronted with a set of options: extend the operational life of the assets, re-power the site or decommission. Every site has its own characteristics, and will require a specific business case.
This introductory session will give an overview of the market potential in Europe, volumes expected to be decommissioned, lifetime-extended or re-powered, regulatory and technical challenges and potential business opportunities for the wind industry.


  • Giles Dickson, CEO, WindEurope
  • Peter Wells, CEO Onshore Wind Europe and SSA, GE Renewable Energy
  • Antonio Lopez-Nicolas, Deputy Head of Unit Renewables and CCS Policy, European Commission

SESSION 1: Lifetime extension in wind

10:45 – 12:15

Session description:

The decision to lifetime-extend relies on a set of legal, technical, and economic factors.
This session will feature a series of presentations, followed by a panel discussion, and look at the different factors that drive such decisions. On the regulatory side, the session will provide delegates with a pan-European legislation overview, comparing the situation in different countries.
On the technical side, the session will address how to assess the reliability of critical turbine components.
On the economic side, the session will look at some indicators of the market price in relation to operations.
The panel discussion at the end will explore how these different drivers combine to affect the business case for lifetime extension.

Followed by panel discussion with all presenters.

SESSION 2: Repowering – a necessary step in achieving RES targets

13:15 – 14:45

Session description:

This session will give insights on the current status of and potential for re-powering in Europe. Like lifetime extension decisions, repowering decisions depend on economic, technical and legal factors. Even more than for lifetime extension decisions, key considerations for re-powering are site-specific, and include spatial planning, community engagement to gain local acceptance, and technological developments, as new turbines may not be suited for older sites.  This session will present some concrete examples and real-world case studies.

Session chairs

  • Pedro Amaral Jorge, President, APREN
  • Luca Bragoli, Head of Public Affairs, ERG


  • The potential and regulatory overview for repowering in Europe
    Viktoriya Kerelska, Head of Advocacy, WindEurope
  • Drivers of the decision between LTE & repowering: pro & cons
    Peter Spengemann, Director of Repowering, WPD
  • Practical examples that illustrate clear comparison when managing old and new assets during decommissioning and construction
    Katrin Duening, Head of International Governmental and Political Relations, ENERCON
  • Involvement of local communities, social acceptance
    Sobia Waheed, Advisor, Danish Energy Agency

SESSION 3: Decommissioning and sustainability strategies(Part 1)

15:15 – 16:15

Decommissioning, a key step to further LCOE reductions

Session description:

Sites where lifetime extension or re-powering is not possible or economically unviable will have to be decommissioned. But even sites that are to be extended or re-powered will also go through some (partial) decommissioning of older parts or assets. This session will share practical know-how and lessons on decommissioning and explain how second-hand markets work. It will also feature a presentation of the regulatory situation across Europe with regards to decommissioning.

Session chair

Claudia Grotz, Chair of WindEurope working group on sustainability


  • Regulatory framework overview across Europe
    Claudia Grotz, Chair of WindEurope working group on sustainability
  • Decommissioning and its costs
    Matthias Brandt, Director, Deutsche Windtechnik AG
  • Second-hand markets
    Patricia Vela, Marketing manager, Surus Inversa

SESSION 3: Decommissioning and sustainability strategies (Part 2)

16:15 – 17:15

Sustainability, Achieving the full circularity of the wind sector through recycling key components of the turbine

Session description:

Achieving the carbon neutrality of the wind sector is a priority for wind industry stakeholders to comply with the Paris agreement.
This session will discuss growing cooperation with key industry sectors:  cement, chemicals and composites. Delegates will also learn about the latest innovative recycling technologies to accelerate wind turbine circularity.

Session chair
