Credit Assessment Load Factor values for Winter 2023: 1 November appeal deadline
The Credit Assessment Load Factor (CALF) values for the Winter 2023 BSC Season, which runs from 1 December 2023 to 29 February 2024, are available from the BSC Portal. If you are the Lead Party of a non-Credit Qualifying BMU, you can appeal an assigned CALF value if you believe it does not accurately represent your expected activity.

Questions about CALF value
Why might my calculated CALF value not accurately represent the expected Balancing Mechanism (BM) Unit activity?
- The CALF calculations for consumption BM Units take the average consumption in the reference season and divide it by the maximum consumption in the reference season. If a consumption BM Unit (e.g. a Supplier BM Unit) contains significant amounts of embedded generation, we can recalculate the CALF values using the Embedded Generation Methodology which takes the generation into account.
- CALF values are calculated using reference data from the same season last year. Therefore, if your portfolio has changed significantly in the last year, the reference data may not be representative of your activity in the Winter 2023 BSC season.
What can I do if I believe the assigned value does not accurately represent the expected BM Unit activity?
If you are the Lead Party of a non-Credit Qualifying BM Unit, you can appeal an assigned CALF value if you believe it does not accurately represent your expected activity.

- To raise an appeal to request that different reference data is used to calculate the CALF Values, please complete the CALF Appeals pro forma in Appendix 5 of the CALF Guidance Note document and email it to [email protected] by Wednesday 1 November 2023. You need to complete at least sections 1 and 2. If sections 3 onwards are not relevant, please detail the reference period that you would like Elexon to use to recalculate the CALF values and why that reference period would be more reflective of the activity in Winter 2023 than the Winter 2022 reference period.
- To raise an embedded generation appeal using alternate reference data, please complete the form in Appendix 7 of the Guidance Note and include the reference period that should be used and why that reference period would be more reflective of the activity in Winter 2023 than the Winter 2022 reference period.
