Transmission Lines
Data on capacity, scheduled trade, actual exchange and congestion income.
The TSOs decide how much capacity is to be transferred, and the capacity for the coming day is published at Nord Pool Spot every day before 10:00.
Scheduled trade on the transmission lines is the flow of electricity from areas of surplus to areas of deficit resulting from the Nord Pool Spots price calculation. The physical exchange is the actual measured exchange of electricity. Negative values indicate export of electricity out of the area to the connected area, and positive values indicate import.
Congestion rent is calculated as the difference in spot prices between the two price areas multiplied by the estimated exchange between the two areas concerned. The international connections to Norway and Sweden are completely at the disposal of NordPool Spot and in return the TSOs receive the congestion rent. In NORDEL (Denmark, Norway, Sweden, Finland, Iceland) the congestion rent is distributed according to a scale agreed upon. With regard to the KONTEK interconnection the congestion rent is paid to Energinet.dk, Vattenfall Europe Transmission and Vattenfall AB (Vattenfall’s trading company in Sweden) according to a scale agreed upon.
The interconnection between Western Denmark and Germany is at the disposal of the market at annual, monthly and daily auctions at which payment for utilization of the interconnection - and thereby the congestion rent - is calculated on the basis of demand and supply. The congestion rent is equally divided between Energinet.dk and E.ON Netz.

| Comment | Please note that the format shown in the example applies to data download as JSON, XML or fetched through the API and is in accordance with the ISO 8601 standard. The format is slightly different when it is shown on screen or downloaded manually as CSV or XLSX. This is mainly due to readability and consideration for Excel users. In preview (in the GUI) all timestamps are shown as (display convention) YYYY-MM-DD hh:mmZ e.g. 2017-07-14 08:00Z. The Z will remind viewers that this is UTC. In download (CSV and XLSX) the date time are exported as YYYY-MM-DD hh:mm e.g. 2017-07-14 08:00. That is without the \u201cT\u201d and the \u201cZ\u201d and the seconds. Excel will recognize it as date-time. The user must remember the convention about time zones. In download (JSON and XML) the full format is used YYYY-MM-DDThh:mmZ e.g. 2017-07-14T08:00Z. |
