As part of the ongoing work to develop Future Arrangements for System Services, SONI and EirGrid have developed proposals for the design of the Day-Ahead System Services Auction (DASSA).

The TSOs have today published a consultation paper on the DASSA Volume Forecasting Methodology for the reserve services.

The consultation period is now open. Responses to the questions set out in this paper should be submitted through either the EirGrid or the SONI portal by 15 November 2024.
