Solar eclipse Electricity Margin Notice: comment

"The National Energy System Operator's electricity margin notice is a standard tool it frequently uses to ask for more power to be available because of tighter margins – it’s a precaution that gives them some extra buffer. Today’s eclipse will mean solar power goes offline earlier than usual and coincides with peak electricity demand so having more power sources available on standby is part of running a robust grid, with the UK’s being one of the most reliable in the world while increasingly going green.

"This year has seen more margin notices issued in the summer because of the frequent heatwaves, which are being made worse and more common by climate change, as extreme heat drives up demand from air con and fans while reducing efficiency of many power sources including gas and nuclear. The only way to bring our climate back into balance is to reach net zero emissions, including rolling out more renewables and upgrading the grid after decades of under investment."
