ACER amends the methodology for calculating scheduled exchanges resulting from single day-ahead electricity market coupling
What is it about?
ACER approves Transmission System Operators’ (TSOs’) proposal to amend the methodology for calculating scheduled exchanges resulting from single day-ahead coupling (SDAC). The amendment, proposed by TSOs on 21 March 2024, was referred to ACER by the European National Regulatory Authorities (NRAs) on 24 May 2024.
The methodology describes how the scheduled exchanges between bidding zones, scheduling areas, and Nominated Electricity Market Operators’ (NEMOs’) trading hubs are calculated in the SDAC.
What are the amendments about?
TSOs deemed it necessary to improve the SDAC algorithm to enable the effective implementation of the 15-minute Market Time Unit (MTU) in the SDAC (required for January 2025).
The amendments will allow handling an increased volume of data within the limited calculation timeframe. To do so, a back-up functionality for the calculation of the scheduled exchanges between bidding zones was introduced.
To foster the implementation of the 15-minute MTU, ACER has also amended the single day-ahead coupling products methodology.
What are the next steps?
TSOs shall implement the amendments by the time the 15-minute MTU becomes operational in the SDAC (required in January 2025).
