Introduction

The N2EX Day Ahead Auction in the UK is a daily auction with physical delivery the following day (d+1). 

Gate closure time is 09:50 GMT / 10:50 CET and results are published at latest 10:00 GMT / 11:00 CET. 


We also offer a daily N2EX test auction with gate closure time 09:50 GMT / 10:50 CET with delivery day the following day. Results are usually published within a few minutes after gate closure.

North Sea Link (NSL)

After the official go-live of the NSL cable, members in NO2 will have the option to submit bids that can be matched in UK and vice versa given that there is capacity available on the NLS cable. This will not lead to any significant operational changes for our UK members already using the N2EX auction, except that the product code will change from N2EX_DA_1 to N2EX_DA_2

The first N2EX Auction using the updated N2EX_DA_2 product code will be held on Thursday 23rd September for delivery Friday 24th September. 


Note that Thursday 23rd is the technical go-live, meaning there will still be zero capacities offered on the NSL cable until the official go-live date, which is delivery day October 1st. 


Preliminary and Final results

Form 23rd of September 2021, the NSL cable and its addition to the N2EX auction is in the technical go-live phase. As a consequence of that, from the 23rd onward, the results, noticeably the flow on the cable, will have to be validated by the TSOs, Statnett and National Grid, before they are final. 

 

This means that the results that are first received is the preliminary results. These are published at the same time as N2EX results were published before the introduction of NSL. These preliminary results still needs to be approved and validated by the TSOs. On a normal day, this will happen before 11:00 CET

 

This is different from how the N2EX results were published previously, as there were no preliminary results, only final. 

Participants in the SDAC Auction and the UK DA market when it was still coupled will be familiar with the concept.
