All NEMOs to modify the threshold that triggers second auction procedure in April and May 2023

Due to the recent market circumstances specifically in The Netherlands, the Nominated Electricity Market Operators (NEMOs) operating the Single Day-Ahead Coupling have decided to modify the lower threshold that triggers the 2nd auction procedure from EUR -150 to EUR -500 per MWh.

The goal of this change is to maintain security of operations by avoiding triggering second auctions in the most affected countries on a regular basis and thus binding operational resources, which could endanger the Market Coupling session by increasing the risk of Full Decoupling.

The change will be implemented as of 15 June (first trading day) for delivery date 16 June, except Czech Republic, where the change will take place from Thursday 22 for delivery date 23 June.

The second auction procedure is triggered when certain price levels are reached in the coupled Day-Ahead auction, in order to allow market participants to review their positions when price levels are higher/lower than usual.

The following countries are affected by the threshold switch to -500 EUR:


– Austria
– Belgium
– Croatia
– Czech Republic
– Estonia
– France
– Germany
– Hungary
– Ireland and Northern Ireland
– Latvia
– Lithuania
– Portugal
– Romania
– Slovenia
– Spain
– The Netherlands

The countries not explicitly mentioned in this note, are not affected by this change.
