Neso activated an Emergency Assistance notice on October 12 to secure 1.2GW of electricity imports. The action followed a delayed return to service for a critical transmission asset managed by National Grid Electricity Transmission.
Why it matters
The measure was taken as an operational tool to maintain system security after reduced network capability threatened grid stability. Electricity supplies for customers remained fully secure throughout the event.
Neso requested an initial 700MW of imports followed by an additional 500MW to manage the system. This total import of 1.2GW was facilitated through a French interconnector cable.
