Interim Coupling go-live
The Interim Coupling project was launched on the request of National Regulatory Authorities in 2018 in order to foster regional integration of Day-Ahead markets in Europe. The project aimed to connect the borders of the so-called 4M MC countries Czechia, Hungary, Romania and Slovakia with the Multi-Regional Coupling. This connection happens through the introduction of implicit capacity allocation on the respective borders. Implicit capacity allocation means that available cross-border capacity is auctioned simultaneously with the traded electricity, to optimise flows and increase efficiency at the borders.
A result of cooperation
The successful new coupling is the result of the close cooperation among the Power Exchanges and Transmission System Operators involved in the Interim Coupling Project: EPEX SPOT, EXAA, HUPX, NordPool EMCO, OKTE, OPCOM, OTE, TGE and TSOs 50Hertz, APG, CEPS, MAVIR, PSE, SEPS, TenneT, Transelectrica. The partners worked closely with national regulatory authorities ANRE, BNetzA, E-Control, ERU, MEKH, URE and URSO.
The go-live of the Interim Coupling project represents a major step.
One step closer to the target model
The go-live of the Interim Coupling project represents a major step towards the achievement of the European Single Day-Ahead Coupling. The next step consists of the introduction of the flow-based capacity calculation method in the so-called Core region, reaching from France to Romania and from Germany to Croatia. This happens in the framework of the Core Flow-Based Market Coupling project. More information on the Core Flow-Based Market Coupling project is available here.
