Explanation IntraDay

On the tabsheet "Table" you will find the data described below. The data is presented per PTU (Program Time Unit), in the columns going from the left to the right you will find:

• ATC, is the Available Transfer Capacity, in this column the capacity available for the intraday cross border allocation is presented. The ATC is based on matched data between the TSOs. Because "netting" is applied it is possible that the ATC exceeds the NTC.
• Requested capacity, in this column the capacity requested by market parties is presented
• Obtained capacity, in this column the capacity allocated to market parties is presented
• Nominated capacity, in this column the capacity actually nominated by market parties is presented, this value can not exceed the value in the column obtained capacity
• NTC, this is the Net Transfer Capacity     

The data presented on the pages related to intraday cross border capacity allocation is from different points in time. The ATC is based on matched data between the TSOs as known at the latest gate closure for capacity request and the Requested, Obtained and Nominated Capacity from the moment of publication. On the pages the moment of publication is shown to avoid misunderstandings about the validity of the data. 
A zero (0) on this webpage in the columns Requested, Obtained and Nominated Capacity can also mean that no allocations or nominations concerning Intraday Capacity have taken place. Normally an empty space should be published but for the time being it will be a zero. For real time ATC you have to visit the website of the intraday Capacity Allocation Platform (https://www.intraday-capacity.com/portal/). 

Data for import and export is presented in separate tables below each other. 

On the border between Germany and the Netherlands the "first come first serve" method is used, this means that the participant being first to ask for capacity is first to be served. On this border the so-called "continuous trading" system is applied which means that capacity can be allocated till 75 minutes before the start of the delivery hour, so there will be 24 gates per day. The allocation is performed on the systems of Deutsche Börse System (DBS). TenneT is the joint allocation operator of the intraday capacity allocation for this border. 

In all cases the capacity is allocated to the market free of charge. 

On the Dutch/German border a nomination obligation applies. If a party does not nominate, the contract value will be settled in unbalance. In case this happens, the values in the columns "obtained capacity" and "nominated capacity" will be different where this can not be the case in normal conditions.
