High-Level Market Design finalised

11.06.2019

It was only at the end of 2018 that the national regulatory authorities of Austria, Germany, Poland and the so-called 4MMC countries (Czechia, Hungary, Romania, and Slovakia) requested the initiation of the interim project for an NTC-based market coupling (“Net Transfer Capacities”) between these countries. The parties involved in the DE-AT-PL-4MMC (“Interim Coupling”) project have completed the High-Level Market Design to be implemented and the national regulatory authorities have confirmed their support for the continuation of the project. This involves a total of eight TSOs that are shareholders and customers of TSCNET Services: 50Hertz (Germany), APG (Austria), ČEPS (Czechia), MAVIR (Hungary), PSE (Poland), SEPS (Slovakia), TenneT (Germany), and Transelectrica (Romania).

The project aims to couple 4MMC and Poland as well as Multi-Regional Coupling (MRC) through the introduction of NTC-based implicit allocation on six borders (PL-DE, PL-CZ, PL-SK, CZ-DE, CZ-AT, HU-AT) and the implementation of a Single Day Ahead Coupling (SDAC). The project envisages a step-by-step transition at the above-mentioned boundaries from the current NTC-based explicit allocation to the flow-based implicit allocation to be implemented in the framework of the CoreFlow-Based Market Coupling Projectas target solution required by regulation. The Interim Coupling significantly contributes to the regional market integration and brings benefits to the market. The current planning envisages the go-live of the interim coupling for the second quarter of 2020.
