Credit Assessment Load Factor values for Spring 2022 appeal deadline

The Credit Assessment Load Factor (CALF) values for the Spring 2022 BSC Season, which runs from 1 March 2022 to 31 May 2022, are available from the Credit/Credit Alerting section under the Financial and Credit menu on the Elexon 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.

How it relates to you

There may be circumstances where your calculated CALF value may 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 Spring 2022 season.

Appeals process

Q. 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 embedded generation appeal, please complete the CALF Appeals pro forma in Appendix 7 of the CALF Guidance document and email it to [email protected] by Tuesday 1 February 2022. A word version of the form can be found on the right hand side of the CALF Guidance document webpage.

  • To find out more about CALF appeals, please see Section 12 of the CALF Guidance Note.

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 document and email it to [email protected] by Tuesday 1 February 2022. 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 Spring 2022 than the Spring 2021 reference period.

To raise an embedded generation appeal using alternate reference data, please complete the Appendix 7 form and include the reference period that should be used and why that reference period would be more reflective of the activity in Spring 2022 than the Spring 2021 reference period.

Holiday CALF appeals

If you wish to request recalculated CALF values for the Easter period, the holiday CALF deadline for the Spring 2022 BSC Season is Tuesday 15 February 2022, 10 working days before the start of the season.

Please request a copy of the Holiday CALF proforma via [email protected].
