The Project Parties involved in the DE-AT-PL-4M MC Project (’Interim Coupling’) have finalized the High-Level Market Design to be implemented and the national regulatory authorities reconfirmed their support for the continuation of the project during a NRA-TSO-NEMO meeting held on 22nd May 2019 in Budapest.

The project aims to couple the 4M MC and Poland and the Multi-Regional Coupling (MRC) by introducing NTC-based implicit allocation on 6 borders (PL-DE, PL-CZ, PL-SK, CZ-DE, CZ-AT, HU-AT) and implement Single Day-Ahead Coupling (SDAC).

The project intends to be a stepwise transition on the afore-mentioned borders from current NTC-based explicit allocation towards the flow-based implicit allocation which is to be implemented in the framework of the Core Flow-Based Market Coupling Project as target solution required by regulation.

The Interim Coupling significantly contributes to the regional market integration and brings benefits to the market before the flow-based day-ahead market coupling go live in the Core region.  

The current planning foresees the go-live of the Interim Coupling in Q2 2020.
