Single Intraday Coupling (SIDC) parties confirm the successful tests have been performed regarding the introduction of a 15-minute Market Time Unit (15-min MTU) capacity allocation between Croatia, Slovenia and Hungary. The expected go-live date is on January 9, 2024 (with the first delivery day January 10, 2024) aiming to enhance intraday trading between the three countries through SIDC.
Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs) involved in the European Single Intraday Coupling (SIDC) are pleased to confirm the successful completion of tests for the go-live of 15-min MTU capacity allocation on the Croatian, Slovenian and Hungarian borders.
The go-live is expected on January 9, 2024 (with the first delivery day on January 10) on the Croatian, Slovenian and Hungarian borders (HR-SI, HR-HU) after which 15-min MTU cross-border capacity will be allocated in the continuous trading through SIDC instead of the current 60-min MTU (implicit (HR-SI, HR-HU) and also explicit (HR-SI)).
In addition, the 15-min MTU product will be introduced in Croatia for trading additionally to the currently available product list.
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.
