Revised Weekly Operational Constraints Update
EirGrid and SONI have published a revised Weekly Operational Constraints Update for Week 27.
The revision reflects the implementation of the next phase in the trial of an increased system limit for the Rate of Change of Frequency (RoCoF).
From Wednesday 1st July, system conditions permitting, the RoCoF limit will be 1.0 Hz/s.
The weekly constraints update is published every Friday evening on the TSO Responsibilities page of SEM-O.com.
