Calling for entries from companies and consortia interested in undertaking a study to evaluate future business models and commercial frameworks that could mitigate associated legal and commercial risks of using refurbished minor wind turbine component parts. 

Integrating refurbished parts into wind turbine maintenance offers significant benefits, including reduced operational costs, resources and emissions, WTG downtime, and supply chain volatility. However, adoption is hindered by legal and commercial uncertainties such as liability, warranties, certification, intellectual property rights, and ownership. 

The Sustainability JIP would like to:

• Assess legal risks: Identify and analyse the perceived legal risks associated with adopting refurbished turbine parts, including challenges related to IPR and ownership.
• Review certification and warranty practices: Investigate current certification processes for refurbished parts and examine issues surrounding warranties and insurance.
• Evaluate business models: Compare existing and emerging commercial frameworks that could mitigate legal and commercial risks, drawing on transferable insights from successful case studies.
• Application of the framework: Demonstrate the framework’s applicability and explore liability and ownership implications through targeted, component-specific case studies. 

The deadline for clarification questions is 5 December 2025.
