The Tuesday’s go-live integrated the borders of Greece and Slovakia (specifically: GR-IT and GR-BG as well as SK-CZ, SK-HU, SK-PL), on which cross-border capacity on is now allocated, starting from 29th November, in the continuous trading through SIDC.
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, including: 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.
SIDC is a joint initiative of NEMOs and TSOs. The first wave of integration went live in June 2018 and involved 15 countries. Poland joined SIDC in the second implementation wave in November 2019.
TGE has been long supporting the integration of the European electricity market. In 2010, a direct-current connection was established between Poland and Sweden via a market coupling mechanism, followed by a link with Lithuania 5 years later. In December 2015, TGE became the Nominated Electricity Market Operator (NEMO) for the Polish bidding zone, and had this status extended for additional 4 years in December 2019. In addition to being active on the SIDC cross-border Intraday Market, the Polish Exchange participates in the European Day-Ahead Market (SDAC), inaugurated on 15 November 2017, which included the implementation of the Interim Coupling project on 17 June 2021 (leading to the extension of cross-border electricity trading onto new interconnections, i.e. with Germany, the Czech Republic and Slovakia, in addition to the existing ones with Sweden and Lithuania).
