EirGrid has today published a consultation paper on the design of the day-ahead system services auction (DASSA).
As part of the ongoing work to develop Future Arrangements for System Services, EirGrid and SONI have developed proposals for the design of the DASSA. These proposals are based on the High-Level Design set out by the SEM Committee (SEM-22-012) and are informed by the collaborative design undertaken with our partners DotEcon and AFRY, by regulatory engagement and industry feedback.
Responses to the consultation, preferably structured in line with the specific questions raised in this paper, should be submitted via the EirGrid consultation portal by 10 May 2024.
Please note your response will be publicly available for viewing on the portal. If you require your response to remain confidential, please clearly state this in your response.
An industry workshop, at which the TSOs will present our proposals and facilitate a Q&A for interested parties, will be scheduled in April 2024 (date to be confirmed and communicated to customers and stakeholders in due course).
