The Frequency Risk and Control Report includes an assessment of the magnitude, duration and likelihood of transient frequency deviations, forecast impact and the cost of securing the system and confirms which risks will or will not be secured operationally.

The requirement for a Frequency Risk and Control Report was introduced following the approval of Security and Quality of Supply Standards (SQSS) modification GSR027. The first version of the report was submitted to Ofgem on 1 April 2021 and approved on 12 May 2021.

The FRCR is produced at least once annually and is consulted on with industry and reviewed by the SQSS Panel ahead of submission to Ofgem.

The 2024 FRCR report and methodology is being consulted between 10 April 2024 and 17 May 2024, and will be submitted to Ofgem for approval on 30 June 2024.
