Ofgem has approved a suite of modifications to energy industry codes to implement the new Electricity System Restoration Standard (ESRS) introduced by the government in a policy statement in April 2021. The ESRS mandates that in the event of a total or partial shutdown of Great Britain’s power grid, the Electricity System Operator must be able to restore 60% of demand on the transmission network within 24 hours, and 100% within five days.
New arrangements for rebooting power grid approved
