New intraday products on German, French and Benelux borders under SIDC

29.10.2020

The European Transmission System Operators (TSOs) are jointly striving for an integrated European electricity market. A key component for market integration is cross-border Single Intraday Coupling (SIDC), which was introduced in June 2018, then called XBID. SIDC aims to increase the overall efficiency of intraday trading through effective competition, increased liquidity, and more efficient use of generation resources. Further progress has now been made along the path to a common market: On 10 December 2020, the competent Nominated Electricity Market Operators (NEMOs), the Belgian and French TSOs Elia and RTE and the two TSCNET shareholders Amprion, one of the four German TSOs, and TenneT, the Dutch-German TSO, will launch new cross-border intraday products at the borders of the bidding zones between Belgium, Germany, France, and the Netherlands.

In concrete terms, 30-minute cross-border products are to be introduced in intraday continuous trading at the Belgian-French border and 15 and 30-minute cross-border products at the Belgian-German, Belgian-Dutch and Dutch-German borders. With the introduction of these intraday products, the TSOs fulfil their obligation to offer cross-zonal capacity for SIDC at their borders with least common multiple of the imbalance settlement periods (ISP) and this on both sides of the respective bidding zone borders. This innovation should improve the possibilities for imbalance management by market parties, closer to real time, as market participants will be able to sell or buy cross-border products with the same resolution as the ISPs of the Belgian, Dutch, French, and German-Luxembourg bidding zones.

Moreover, Belgian and Dutch market participants will then have access to the existing market liquidity of 15-minute products in Germany and Austria and 30-minute products in Germany and France respectively, where these cross-border products have already been established. The XBID platform for SIDC comprises a common IT system with a shared order book, a capacity management module, and a shipping module. Via this platform, the new products will be available for cross-border trade in Belgium and the Netherlands from 10 December 2020 and will complement the currently existing 60-minute cross-border products. Bids for 15-minute and 30-minute products will be included in the NEMOs’ shared order books.

As SIDC represents a pan-European solution, numerous TSCNET shareholders are involved in the solution for market integration. In addition to the above mentioned TSOs, 50Hertz, APG, ČEPS, ELES, HOPS, MAVIR, PSE, SEPS, Transelectrica, and TransnetBW as well as several TSCNET customers are also part of SIDC.

New cross-border intraday products will be launched in December 2020 under SIDC
