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.

Automated intraday capacity allocation at Austrian-Swiss border

05.10.2020

The separation of the bidding zones of Germany (including Luxembourg) and Austria on 1 October 2018 has imposed additional tasks on the transmission system operators (TSOs) directly concerned and also on neighbouring TSOs, notably as regards congestion management. Bidding zones are areas where a wholesale electricity market price applies, and the AT-DE/LU separation resulted in increased demand for intraday cross-border capacity at the Austrian-Swiss border. The two TSCNET shareholders APG from Austria and Swissgrid, the TSO from Switzerland, have reacted to this changed market situation and introduced automated, platform-based intraday capacity allocation.

A border-specific solution was necessary because the Austrian-Swiss border cannot be integrated into Single Intraday Coupling (SIDC, originally introduced as XBID in 2018). Therefore, the intraday allocation of cross-border capacities is still carried out via explicit allocations, but now in an automated process. On 23 September 2020, with the first delivery on 24 September, telephone allocation was switched to a platform-based allocation. The IT platform used – Intraday Capacity Service (ICS) – allocates capacities in accordance with the “first come, first served” principle. After almost two weeks of automated allocation, the two TSOs consider the new, easier intraday trading procedure a success. Swissgrid has already been applying this more efficient allocation of cross-border volume on the Swiss borders with Germany and France.

New Local Implementation Project under SIDC

09.07.2020

European transmission system operators (TSOs) are committed to the European Energy Union by collectively working towards an integrated European electricity market. A key component for market integration is cross-border Single Intraday Coupling (SIDC), which was introduced as XBID in June 2018. SIDC is designed to increase the overall efficiency of intraday trading through effective competition, increased liquidity, and more efficient use of generation resources. Currently, the markets of 22 countries are coupled through SIDC: Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Romania, Slovenia, Spain, and Sweden. With the inclusion of the Slovakian Nominated Electricity Market Operator (NEMO) OKTE and TSCNET shareholder SEPS, the TSO from Bratislava, the project also extends to Slovakia.

Within the framework structure of the SIDC, Local Implementation Projects (LIPs) provide for the expansion of the market coupling, and a new project has now been established as LIP 17. The NEMOs and TSOs from the Czech Republic, Hungary, Poland, and Slovakia – the TSCNET shareholders ČEPS, MAVIR, PSE, and SEPS – have proposed to implement SIDC across the borders between Slovakia-Czechia, Slovakia-Hungary, and Slovakia-Poland. The SIDC Steering Committee approved on 7 July and the LIP 17 roadmap will now be elaborated in more detail.

The SIDC solution comprises a common IT system with a shared order book, a capacity management module, and a shipping module. In addition to the TSOs mentioned above, the TSCNET shareholders 50Hertz, Amprion, APG, ELES, HOPS, TenneT, Transelectrica, and TransnetBW as well as the TSCNET customers Creos from Luxembourg and Energinet from Denmark are also part of SIDC.

SIDC: Massive growth in trading volume

02.04.2020

European cross-border Single Intraday Coupling (SIDC) was introduced in June 2018 (then called XBID) to increase the overall efficiency of intraday trading through effective competition, increased liquidity, and more efficient use of generation resources. The overarching objective is the integration of the European energy market. In November 2019, SIDC was extended in a second go-live, so that currently the markets of 22 countries are coupled through SIDC: Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Luxembourg, Norway, the Netherlands, Portugal, Spain, Sweden (first go-live), and Bulgaria, Croatia, the Czech Republic, Hungary, Poland, Romania, and Slovenia (second go-live).

The Nominated Electricity Market Operators (NEMOs) from the seven countries of the second go-live report significant growth in trading volume in the coupled intraday market. The Hungarian NEMO HUPX, for example, recorded an average monthly trading volume of around 75,600MWh from December 2019 to February 2020 compared to 7,600MWh in the same period of the preceding year; in the Czech Republic, the volume has increased eightfold. The other NEMOs are also registering significant growth rates. A total of 36 million trades have been executed since SIDC first went live, and the system continues to operate reliably after the second wave.

The SIDC solution is based on a common IT system with a shared order book, a capacity management module and a shipping module. The TSOs cooperating in SIDC include the TSCNET shareholders 50Hertz, Amprion, APG, ČEPS, ELES, HOPS, MAVIR, PSE, TenneT, Transelectrica and TransnetBW, as well as the TSCNET customer Creos from Luxembourg and Energinet from Denmark. With the accession of the NEMO OKTE and further TSCNET shareholder SEPS, the TSO from Bratislava, the project has meanwhile been extended to Slovakia. A third go-live to expand continuous cross-border intraday trading to Greece and Italy is expected in the first quarter of 2021.

Single Intraday Coupling expanded

08.11.2019

Europe-wide intraday coupling is a key component for the completion of the European internal energy market. To help achieve this goal, the European cross-border Single Intraday Coupling (SIDC) solution was launched in June 2018 (then called XBID), standing for a significant step towards a single integrated continent-wide intraday market. A market of this kind increases the overall efficiency of intraday trading through effective competition, increased liquidity and more efficient use of generation resources across Europe. The SIDC solution is based on a common IT system with a common order book, a capacity management module and a shipping module.

The participating countries were initially Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Norway, the Netherlands, Portugal, Spain and Sweden. SDIC will now be expanded and continuous electricity trading will be possible across seven further countries: Bulgaria, Croatia, the Czech Republic, Hungary, Poland, Romania and Slovenia. Nominated electricity market operators (NEMOs) and the participating transmission system operators (TSOs) have confirmed the go-live of the extended SIDC and two additional local implementation projects on 19 November with first deliveries on 20 November.

TSOs already collaborating in SIDC include the TSCNET shareholders 50Hertz, Amprion, APG, TenneT, TransnetBW and Energinet as well as the TSCNET client Creos from Luxembourg. With the second wave, six more shareholders follow, namely ČEPS, ELES, HOPS, MAVIR, PSE and Transelectrica.

Second go-live wave of XBID

13.06.2019

The successful go-live of XBID, the European cross-border Single Intraday Coupling (SIDC) solution, on 12/13 June 2018 was a significant step towards a single integrated continent-wide intraday market. Such an integrated market increases the overall efficiency of intraday trade through effective competition, increased liquidity and more efficient utilisation of generation resources across Europe. Today the first anniversary of XBID is celebrated and over 16 million trades have been executed since its launch.

The SIDC partners look back on a successful first year of operation with a stable and robust system performance as well as a high and growing number of trades across Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Norway, the Netherlands, Portugal, Spain, and Sweden. The integration of seven additional countries into the SIDC region is expected in the fourth quarter of 2019. A pre-launch event for the second wave is planned for the beginning of October 2019 and a trial period will also be arranged with the market parties. The countries for this second go-live wave are Bulgaria, Croatia, the Czech Republic, Hungary, Poland, Romania, and Slovenia.

The TSOs already cooperating in XBID include the TSCNET shareholders 50Hertz, Amprion, APG, TenneT, and TransnetBW as well as the TSCNET client Creos from Luxembourg. Further shareholders are to follow with the second wave, namely ČEPS, ELES, HOPS, MAVIR, PSE, and Transelectrica.
