The Nominated Electricity Market Operators and Transmission System Operators from Slovakia (NEMO) , Czech Republic, Poland and Hungary established a new Local Implementation Project (LIP 17) to couple intraday electricity markets under Single Intraday Coupling (SIDC, formerly known as XBID project) covering borders between Slovakia – the Czech Republic, Slovakia – Hungary and Slovakia – Poland. The Steering Committee of SIDC approved the establishment of a new LIP on July 7. The envisaged go-live of LIP 17 will be communicated at a later stage, reflecting the LIP 17 roadmap which is currently under development.
The SIDC solution is based on a common IT system with one Shared Order Book (SOB), a Capacity Management Module (CMM) and a Shipping Module (SM). 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 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. The purpose of the SIDC initiative is to increase the overall efficiency of intraday trading.
