All NEMO Committee's Fourth Annual Conference Reviews SDAC/SIDC Performance and Charts Future Market Coupling Priorities

The All NEMO Committee held its fourth Annual Conference in Brussels on 29 September 2026, bringing together the European Commission, ACER, NRAs, NEMOs, TSOs and market participants to review the first anniversary of the SDAC 15-minute Market Time Unit (MTU), discuss SIDC enhancements, and debate future priorities for deeper European electricity market integration.

The conference consolidates the governance narrative around Europe's most integrated day-ahead and intraday coupling mechanisms, publicly reporting a 100% operational success rate for SDAC sessions in 2025 and signalling where regulators and market operators see remaining gaps and priorities for further integration, which shapes the trajectory of future CACM-related design work.

While this is a high-level governance and reporting forum rather than a discrete rule change, it functions as an authoritative checkpoint on the maturity of SDAC/SIDC market coupling following the 15-minute MTU transition. The reported 100% success rate and explicit institutional engagement (European Commission, ACER) indicate the reform is now in a stabilized operational phase, with discourse shifting toward next-generation integration priorities (security of supply, renewables integration, flexibility) rather than implementation risk. This event is best tracked as a market-impact/review milestone that may seed future PROPOSAL or CONSULTATION events if 'remaining gaps' identified in the afternoon panel are formalized into concrete regulatory initiatives.
