Communication note
15 April 2021: details of the SDAC webinar on the implementation of the DE-AT-PL-4M MC (Interim Coupling) Project

The DE-AT-PL-4M MC project, aims to connect the borders of 4M MC with the Multi-Regional Coupling (MRC) by introducing Net Transmission Capacity based (NTC-based) implicit capacity allocation on six borders (PL-DE, PL-CZ, PL-SK, CZ-DE, CZ-AT, HU-AT). The launch of the project is targeted for 10 June 2021. It will mark the transition to a single coupled auction for the day-ahead market across the countries covered by MRC and 4M MC. Against that background, the project represents a milestone for the completion of the European Single Day-Ahead Coupling (SDAC).

NEMOs and TSOs will arrange a webinar to provide market participants with detailed information about the expected changes and the member tests scheduled for the second half of May.

The webinar will be held on 21 April 2021 from 14:30 till 16:30.
