The average length of Power Purchase Agreements (PPAs) for wind energy in the UK is forecasted to increase from 24 years in 2024 to 26 years by 2028. This represents a steady year-on-year growth as agreements extend slightly over this period. Compared to 2023, where the average length stood at around 23 years, the trend indicates an increasing confidence in long-term commitments within the wind energy sector. The compound annual growth rate (CAGR) over the five years is modest, reflecting a stable yet incremental shift toward longer agreements.
Future trends to watch for include:
- Growing interest in renewable energy investments may push PPA durations even longer as stakeholders seek lasting returns.
- Technological advancements in wind energy systems could influence the structuring of agreements and duration commitments.
- Policy changes and government incentives might further impact agreement structures and durations, encouraging better long-term planning.
