UK National Grid issues a "reduced margin" notice for the Eclipse

The UK's National Electricity System Operator (NESO) Electricity Control Centre has issued an "Electricity Margin Notice" covering a four hour period around the partial solar eclipse on Wednesday.

At the peak of the eclipse just after 17h UT, 90-95% of the sun will be obscured over the UK, cutting the power that PV solar cells can produce substantially for a period of time by up to 1760 MW. This, combined with the evening peak demand, has prompted NESO to issue the notice.

The Electricity Margin Notice is not a warning of impending power cuts. Instead it's letting the power generation industry know that there's a period when the safety margin will be reduced more than they want it to be, and therefore inviting flexible generation options to be made available at short notice should it be required. This is a normal type of request for this kind of event.
