EirGrid and SONI have published a revised weekly constraints update for the current Week 40 2026. 

The below notes have been updated in the Other Constraints/Notes/Risks Table: 

  • Ireland Autumn transmission ratings are in place
  • Maximum continuous output of unit HNC limited to 730 A (amps) due to temporary derating of Finglas-Huntstown 220 kV circuit. This equates to approximately 302 MW exported but is subject to variation.

The weekly constraints update is published every Friday evening on the General Publications page of SEM-O.com.
