On October 27, 2021, the market unification of the Bulgarian market area with the Single Day-Ahead Coupling (SDAC) through the Bulgarian-Romanian border was successfully launched. For the first time, the inter-zone capacity between Romania and Bulgaria was implicitly allocated for a delivery day - October 28, 2021.

The integration of the Bulgarian-Romanian border into the Single European Market "day ahead" SDAC expands the participation of our country in the common electricity market and completes the full integration of the region of Southeast Europe into the market segment. The introduction into operational work of the market union between Bulgaria and Romania in the time segment "day ahead" marks another important stage in the process of integration of the European electricity markets and the completion of the European target model.

The European day-ahead single market allows for the simultaneous calculation of electricity prices and cross-border flows in the region, with the efficient use of the electricity system and cross-border infrastructure aiming to maximize the benefits for all market participants.

After the integration of the Bulgarian market area to the south with the markets of Greece and Italy, the connection of the country with the common European market "day ahead" and to the north across the Bulgarian-Romanian border is already a fact.

The successful accession of the Bulgarian-Romanian border to the Single European Market "day ahead" is the result of close cooperation between Bulgarian and Romanian electricity transmission system operators and electricity market operators - ESO EAD, CN Transelectrica SA, BNEB EAD and OPCOM SA, and support of the national regulatory authorities of Bulgaria and Romania.

For the European Single Market the day ahead - SDAC

SDAC allocates limited cross-border transmission capacity in the most efficient way, connecting wholesale electricity markets from different market areas through a common algorithm. At the same time, restrictions on cross-border capacity are taken into account in order to maximize social well-being in the European countries covered.

The aim of the SDAC is to build a single pan-European market in the day-ahead segment. An integrated day-ahead market increases the overall efficiency of trade by fostering competition, increasing liquidity and enabling the full use of electricity generation resources across Europe.
