We’ve published the Weighting Factors for the 2025/26 Delivery Year, accessible via the Monthly Weighting Factors dropdown in the Settlement Data section—alongside figures for the 2024/25 Delivery Year.
Looking for previous data? Historical Weighting Factors, including figures from 2023/24 and earlier, can be found under the Key Payment Figures dropdown on the same webpage.
Why it matters? Monthly Weighting Factors are applied to:
- Capacity Market Supplier Charge
- Supplier Capacity Market Credit Cover
- Capacity Provider Payments
These payments shift from month to month based on demand, with higher charges when demand is high (typically this is first half of the Delivery Year) and lower charges during periods of low demand.
