Second Auction was decommissioned in SDAC as of 29 January 2025 (trading day).

In early 2024 the Nominated Electricity Market Operators (NEMOs) cooperating within the Single Day-Ahead Coupling (SDAC) conducted a Public Consultation related to the potential removal of the Second Auctions.
As a result of the consultation and following the relevant National Regulatory Authorities approvals, the Second Auctions are no longer applied for the following countries as of 29 January 2025 (trading day): Austria, Belgium, Croatia, Czech Republic, France, Germany, Greece, Hungary, Netherlands, Portugal, Republic of Ireland, Romania, Slovakia, Slovenia and Spain.
The change aims to optimize the market coupling process in preparation for the launch of the 15-minute SDAC products, which is planned for 11 June 2025. By removing the second auctions in a coordinated manner, the whole SDAC process benefits from more contingency in the daily operational process, thus preserving its operational reliability and reducing operational risks, including that of decoupling.
