DETAILS

If a prolonged electricity shortage affects a specific region, or the whole
country, electricity rationing may be necessary. The Electricity Supply
Emergency Code (ESEC) outlines the process for ensuring fair distribution
nationally while still protecting those who require special treatment, using a
process known as ‘rota disconnections’.


NOVEMBER 2019 UPDATE

From 1 April 2019 there is a legal separation of powers between the National
Grid Transmission Owner (TO) and National Grid Systems Operator (SO). This
document has been updated to reflect the new role of the National Grid
Electricity System Operator (ESO).
