Successful Go-Live of Polish Multi-NEMO day-ahead market coupling
On February 9, 2021, day-ahead auctions run by multiple Nominated Energy Market Operators (NEMOs) were successfully launched in Poland, the so-called Multi-NEMO Arrangements (MNA) go-live.

The aim of Single Day-Ahead Coupling (SDAC) is to create a single pan-European day-ahead electricity market. An integrated market boosts overall trading efficiency by promoting effective competition, increasing liquidity, and enabling the efficient use of generation resources and transmission capacity across Europe.

The SDAC process in the Polish market has so far been carried out by TGE. Along with the implementation of the multi-NEMO formula, both EPEX SPOT and Nord Pool also started operating in this area. The inclusion of new NEMOs in the Polish market is another step to strengthen European cooperation in the energy sector.

Thanks to the Market Coupling integration mechanisms, the European electricity market is constantly increasing liquidity while the coordinated process of market price formation and transmission capacity allocation contributes to the increase of social welfare in the coupled regions.

The project parties involved include the Polish TSO PSE and three NEMOs EPEX SPOT, Nord Pool and TGE.
