Official UK-wide winter energy blackout times pinpointed in worse case scenario

The schedules for each severity published in the Electrical Supply Emergency Code are described as “the default rota disconnection plan”.

However, the BEIS document also notes, “detailed timings of disconnections and reconnections will be confirmed by an activation schedule issued by the National Grid Electricity System Operator.”

Level one, for example, begins with load block A experiencing a three-hour blackout in time period 1 — that is from 12.30am to 3.30am — on Mondays, then again from 3.30pm to 6.30pm on Wednesdays and 12.30am to 3.30am on Fridays.

Under level one, each load block experiences either three or four three-hour blackouts per week. Under level two, this increases to five–eight three-hour blackouts per week, eight–eleven blackouts under level three, and so on with increasing frequency per level.

Detailed default disconnection rotas for some of the severity levels can be seen above — the rest are published in the Electrical Supply Emergency Code on the BEIS website.
