European Single Intraday Coupling (SIDC)
Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs) confirm the target date for the launch of SIDC (formerly known as XBID) and the go-Live of 2 further Local Implementation Projects on 19th November with first deliveries on 20th November. This confirmation follows the successful completion of testing and the first Market Trial period. The November 2019 go-live date is still subject to completion of the required go-live preparation and launch activities.
Marking another important step towards expanding the single integrated European Intraday market, the target go-live with the 2 additional Local Implementation Projects will expand the continuous trading of electricity across the following countries: Bulgaria, Croatia, Czech Republic, Hungary, Poland, Romania and Slovenia. They join the existing countries already operating the SIDC: Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Norway, The Netherlands, Portugal, Spain and Sweden. A 3rd wave go-live is expected by the end of 2020.
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 project’s reach as long as transmission capacity is available. The intraday solution supports both explicit allocation on the Croatian/Slovenian and French/German borders (as requested by the respective NRAs) 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.
