Single Intraday Coupling (SIDC) parties confirm the successful fourth wave go-live integrating Greece and Slovakia, which joined SIDC on 29 November. Intraday trading now extended across 25 countries coupled through SIDC.
Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs) involved in the European Single Intraday Coupling (SIDC – formerly known as XBID) are pleased to confirm the successful go-live of the fourth launch of SIDC.
The go-live on 29 November integrated the Greek and Slovakian borders (GR-IT and GR-BG and SK-CZ, SK-HU, SK-PL) on which cross-border capacity on is now allocated, starting from 29 November, in the continuous trading through SIDC.
The integration of Greece and Slovakia into the Single Intraday Coupling marks another important milestone towards the single integrated European Intraday market, which is now entirely completed.
SIDC currently couples the continuous intraday markets of 25 countries: 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.
The SIDC solution is based on a common IT system with one Shared Order Book, a Capacity Management Module and a Shipping Module. It allows for orders entered by market participants for continuous matching in one bidding zone to be matched by orders similarly submitted by market participants in any other bidding zone within the project’s reach as long as transmission capacity is available. The intraday solution supports both explicit allocation (where approved by the respective National Regulatory Authorities) and implicit continuous trading. It is in line with the EU Target model for an integrated intraday market.
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. The purpose of the SIDC initiative is to increase the overall efficiency of intraday trading.
