What changed

EPEX SPOT and ECC confirmed the successful launch of both the SDAC Day-Ahead market (first trading day 30 September 2026) and the SIDC Intraday Auction (first trading day 9 September 2026) in Estonia, Latvia and Lithuania, completing EPEX SPOT's full spot power trading suite in the Baltics. The source adds that this builds on the earlier Intraday Continuous launch of 25 November 2025 and was enabled by implementation of the Baltic Multi-NEMO Arrangement (MNA) under CACM, with clearing provided by ECC.

Why it matters

The addition of SIDC Intraday Auction alongside the already-reported SDAC Day-Ahead go-live means Baltic participants now have access to EPEX SPOT's complete spot product range (Day-Ahead, Intraday Auction, Intraday Continuous), deepening multi-NEMO competition with Nord Pool EMCO across both day-ahead and intraday timeframes, not just day-ahead as previously captured. This broadens the scope of market design impact beyond the original event record to include intraday price formation and liquidity dynamics.

MD analysis

This update materially expands the scope of the originally recorded go-live event: it confirms the day-ahead milestone already tracked but newly establishes that a parallel intraday auction market coupling also went live just three weeks earlier, and situates both within a sequence that began with Intraday Continuous trading in late 2025. From a design perspective, this suggests the Baltic Multi-NEMO Arrangement was implemented as a phased rollout across trading timeframes rather than a single-day transition, with ECC's clearing extension being a necessary enabling condition. The framing remains operational/announcement rather than regulatory, indicating no further approval steps are pending; attention should now shift to monitoring whether competitive dynamics (pricing, liquidity, NEMO market share) materialize across both day-ahead and intraday segments, as the operator explicitly anticipates benefits seen in other multi-NEMO markets.
