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 1st April 2021 and approved on 12th 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 2023 FRCR report and methodology is being consulted between 13th February 2023 and 24th February 2023. It will concentrate on minimum inertia requirements and be submitted to Ofgem for approval on 31st March 2023.
