Solar curtailment
Solar expanded faster than any energy source in history. This rapid growth has created a new market dynamic: On sunny days, Europe now generates more solar energy than it can immediately use or store.
The numbers
- 7.3 TWh solar curtailed in 2025
- Capture rates down to 17% in Spain
- Curtailment spreading beyond Germany to new markets
Key takeaways
- Why curtailment matters: 7.3 TWh curtailed, expanding beyond Germany and Spain
- Value squeeze: Capture rates hit 17% in Spain, challenging profitability
- Two curtailment types: Economic (negative prices) vs technical (grid protection)
- New strategy: Shift from maximising output to maximising value through storage and flexible deman
- Kpler intelligence: Proprietary forecasts for capture prices and curtailment
