Can a Capacity Market Notice be issued for any period less than four hours away?
No, at least four hours' notice needs to be given for a Capacity Market Notice to be first communicated as being active. Regardless of the Capacity Market Notice process National Grid ESO's control room will continue to monitor system margin and communicate any issues closer to real time through operational messages communicated on the System Warnings page of BMRS.
