EirGrid and SONI published yesterday a revised weekly constraints update for the current Week 40.

The revision reflects an update to active Transmission Constraint Groups.  

 

S_NBMIN_MINNI1 and S_NBMIN_MINNI2 are ACTIVE from 1st October 2020.

S_NBMIN_MINNIU and S_NBMIN_MINNI3 are INACTIVE from 1st October 2020.

 

The change is required for dynamic stability during a planned outage of B31 with B22 available in open-cycle mode only.

The weekly constraints update is published every Friday evening on the TSO Responsibilities page of SEM-O.com, alongside the current monthly update.
