Further to the press release issued by the NEMO Committee on 19 December 2024 and to what has been communicated during today’s meeting of the Market Coupling Consultative Group, GME announces that the go-live of products with a 15-minute Market Time Interval (MTU), in the Day-Ahead Market (MGP)/Single Day-Ahead Coupling (SDAC), will take place on the trading day of 11 June 2025, with delivery date on 12 June 2025.

Concurrently with the go-live of products with a 15-minute MTU, as previously indicated in its Consultation Document 01/2024, GME will also make available, in the Day-Ahead Market, products with a 30-minute market time interval, in addition to the already available products with a 60-minute market time interval.

In this regard, with a view to enabling the testing of the new products, GME will organise blank test sessions with market participants beginning on 31 March 2025. The details of the tests, including the timetable of the test sessions and the participation procedure, will be made known with a subsequent communication well in advance.
