Intraday markets are an important tool for market parties to keep positions balanced as injections and/or off-take may change between the day-ahead timeframe and real-time operations. The growth of intermittent generation capacity has increased the importance of efficient Intraday markets. In this context, the European Commission has established a Target Model for Intraday, based on continuous energy trading where cross-zonal transmission capacity is allocated trough implicit continuous allocation. This model has been laid down in the Framework Guidelines for Capacity Allocation and Congestion Management (CACM).
In response to this, the Cross-Border Intraday (XBID) Market project is a joint initiative by the Power Exchanges (PXs) and Transmission System Operators (TSOs) from 14 countries, to create a joint integrated intraday cross-border market. The single intraday market will enable continuous cross-border trading across the entire Europe. This single intraday market solution will be based on a common IT system with one Shared Order Book, a Capacity Management Module and a Shipping Module.
For more than three and a half years E-Bridge has been supporting the XBID TSOs and PXs in the implementation of the Single Intraday Market Coupling. In this period, among others the following project phases have been covered:
- Specification phase (completed)
- Design phase (completed)
- Development phase (completed)
- Testing phase (in progress)
- Go-Live preparations (in progress).
E-Bridge in its role of Project Management Office (PMO) for the joint TSO/PX organization has been acting as “Secretary General”, coordinating with the conveners of all project bodies and ensuring the overall consistency of the project. The project organization consists of several task forces responsible for specific deliverables. In addition to the project management services, E-Bridge convenes several Task Forces and provides expertise inputs on topics like
- market design,
- CACM compliance,
- pre- and postcoupling processes,
- operational procedures,
The participating project parties are: 50 Hertz, Amprion, APG, BritNed, Creos, Elia, Energinet.dk, EPEX SPOT, Fingrid, GME, National Grid Interconnectors, Nord Pool, OMIE, RTE, Statnett, Svenska Kraftnät, Swissgrid*, TenneT BV, TenneT GmbH, and TransnetBW.
