SOEF Markets - FASS - DASSA Product Review Locational Methodology Industry Webinar Slides - June 2024

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). These proposals are based on the High-Level Design set out by the SEM Committee (SEM-22-012) and look to review the reserve products to be procured in the DASSA, and the development of a locational methodology that would support RES-E (electricity from renewable generation sources) objectives.
