Nord Pool and CROPEX Join SDAC in Slovenia via Multi-NEMO Arrangement Go-Live

On 21 October 2026, the Multi-NEMO Arrangement (MNA) in Day-Ahead Market Coupling went live in Slovenia, with Nord Pool and CROPEX joining the Single Day-Ahead Coupling (SDAC) framework in that bidding zone.

The addition of a second and third NEMO (Nord Pool and CROPEX) to operate alongside the incumbent NEMO in Slovenia introduces NEMO competition in the Slovenian day-ahead market, part of the broader SDAC harmonisation effort across Europe, and is expected to increase trading opportunities, liquidity and market efficiency in the region.

This event represents a concrete operational expansion of the SDAC Multi-NEMO Arrangement model into Slovenia, following the pattern already established in other bidding zones across Europe. By allowing Nord Pool and CROPEX to operate as additional NEMOs in Slovenia alongside the incumbent, the design introduces NEMO-level competition within a single bidding zone while preserving the single price coupling algorithm across the pan-European day-ahead market. The involvement of twelve named regional parties (APG, BSP, CROPEX, ELES, EPEX, EXAA, GME, HOPS, HUPX, MAVIR, NP, TERNA) signals a coordinated regional project spanning Austria, Slovenia, Croatia, Hungary and Italy interconnections. From a market design perspective, this is a scope-expansion milestone rather than a rule change: the underlying SDAC algorithm, price coupling methodology and CACM-based governance are unchanged, but the number of market operators market participants can choose from in Slovenia increases, which should tighten bid-ask spreads and improve price convergence with neighbouring markets. No regulatory decision, consultation or implementation deadline is disclosed in this release; it documents the operational completion of what was presumably a longer MNA onboarding process (testing, parallel running, regulatory sign-off) not detailed in this source.
