As part of the ongoing work to develop Future Arrangements for System Services, EirGrid and SONI have shortlisted four options to address the period between the end of the current DS3 Regulated Arrangements and the go-live of the DASSA (including the TSOs' recommended option). The TSOs have today published a consultation paper on the DS3 System Services Tariffs to FASS ('The Gap') Consultation Paper. Responses to the question set out in this paper should be submitted through either the EirGrid or the SONI portal by 25 March 2025.
