This modification arises as a result of both Action 1 of our report on the 9 August 2019 electricity system incident, and Action 5 of the Government’s Energy Emergencies Executive Committee report into the incident. It seeks to ensure the appropriate balance can be reached between the costs of managing system frequency, and the risks mitigated in doing so.
