Paris, 6 February 2024.
- Anniversary: following the 5th anniversary of the Single Intraday Coupling, which took place in June 2023, all Nominated Electricity Market Operators (NEMOs) and all Transmission System Operators (TSOs) celebrate this month the 10th anniversary of the Single Day-Ahead Coupling.
- Both platforms enhance cross-border electricity exchanges in 27 and 25 countries respectively with a total population over 440 million. In 2022 an annually traded volume of 1794 TWh was channelled through these platforms.
- Market integration and cooperation strengthen security of supply, generate substantial social welfare gains, promote competition and support decarbonisation in Europe.
It was in 2014, when NEMOs and TSOs voluntarily decided to build upon the previously existing Day-Ahead regional markets and stepwise coupled all regions in Europe by means of one algorithm in the Single-Day Ahead Coupling. Today both platforms embody market integration, as they couple all European bidding zones and enhance cross-zonal trade by allocating the grid capacity in the most efficient way.
Market coupling is crucial for system resilience and grid stability across Europe. An integrated market enables the efficient management of weather-related fluctuations in renewable generation and helps to mitigate security of supply risks derived from unexpected disruptions in the supply of primary energy sources.
About SDAC
SDAC allocates scarce cross-border transmission capacity in the most efficient way by coupling wholesale electricity markets from different regions through a common algorithm, simultaneously taking into account cross-border transmission constraints, thereby maximising social welfare. The aim of SDAC is to create a single pan European cross zonal day-ahead electricity market. An integrated day-ahead market increases the overall efficiency of trading by promoting effective competition, increasing liquidity and enabling a more efficient utilisation of generation resources across Europe.

About SIDC:
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.
