The Nominated Electricity Market Operators and Transmission System Operators from Slovakia, Czech Republic, Poland and Hungary established a new Local Implementation Project to couple intraday electricity markets under Single Intraday Coupling (SIDC) covering borders between Slovakia and the Czech Republic, Slovakia and Hungary and Slovakia and Poland.
The SIDC solution is based on a common IT system that 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 coupled area as long as transmission capacity is available.
The intraday solution supports both explicit and implicit continuous trading, while 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.
A more detailed roadmap is currently under development.
