Greece, together with Slovakia, has successfully joined the European Single Intraday Coupling (SIDC) for electricity. This move represents the completion of the European intraday market integration.

Greece and Slovakia were in the fourth wave of integration within the European Single Intraday Coupling (SIDC). Greece was late in establishing its power exchange, which happened in November 2020.

The go-live integrated the borders of both Greece and Slovakia (GR-IT and GR-BG as well as SK-CZ, SK-HU, SK-PL), on which cross-border capacity is now allocated, starting from November 29, in the continuous trading through SIDC.

The integration process of the European intraday market has been completed

With the fourth implementation wave, the integration process of the European intraday market has been completed and electricity trading on the markets of all 25 countries participating in the SIDC has been coupled, according to Poland’s power exchange Towarowa Giełda Energii (TGE).

SIDC consists of Austria, Belgium, Bulgaria, Croatia, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Norway, the Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, and Sweden.

Intraday coupling is a key component for completing the European internal energy market

It doesn’t include the three coastal European Union member states – Cyprus, Ireland, and Malta. Norway is part of the group as the only non-EU country.

SIDC is a joint initiative of nominated electricity market operators (NEMOs) and transmission system operators (TSOs). The first wave of integration went live in June 2018 and involved 15 countries.

European-wide intraday coupling is a key component for completing the European internal energy market. With the rising share of intermittent generation in the European generation mix, connecting intraday markets through cross-border trading is an increasingly important tool for market parties to keep positions balanced.
