As ROC-supported wind and solar projects approach the end of their subsidy periods in 2027, asset owners face a critical decision: decommission or repower. Repowering offers the opportunity to extend site life and increase capacity, but it comes with challenges that can rival new development. This session explores the complexities of repowering, lessons from international markets, and strategies for managing aging renewable assets in the UK.
- The scale of projects losing ROC support and the economic case for repowering versus decommissioning
- Why repowering can be as difficult as new development—planning constraints, grid connection issues, and site complications
- Commercial uncertainty facing ageing ROC assets, including exposure to wholesale market volatility, and electricity generator levy implications.
- Decisions around repowering, life extension, or merchant operation.
