ACER amends the EU electricity single day-ahead coupling products methodology to enhance market flexibility

ACER approves Nominated Electricity Market Operators’ (NEMOs’) proposal to amend the single day-ahead coupling (SDAC) products methodology.

The methodology lists all products that are eligible for inclusion within the EU single day-ahead coupling.

What are the amendments about?

NEMOs deemed it necessary to amend the SDAC products methodology to:

• enable the implementation of the 15-minute Market Time Unit (MTU) products into the SDAC;
• remove entry barriers for those market participants trading 15-minute MTU products; and
• allow them to buy and sell electricity for each 15 minutes during the day, enhancing market flexibility.

In its Decision 13-2024, ACER has revised NEMOs’ proposal and agreed to introduce a clear division between product categories, as well as to improve the overall structure and clarity of the document.

To foster the implementation of the 15-minute MTU, ACER has also amended the methodology for calculating scheduled exchanges resulting from single day-ahead electricity market coupling.

What are the next steps?

NEMOs shall implement the amendments by the time the 15-minute MTU becomes operational in the SDAC (required by January 2025).
