Schedule Management

The operational processing of the Schedule Management at TenneT is centrally located at our control centre in Lehrte.

In accordance with the German market regulations (conforming to the European Standard ESS), the nomination process is automated. The customer systems are informed regarding the current status of their schedule registration with defined messages.

To guarantee smooth operations between the control centre and customer systems, a coordinated processing of these messages is necessary. Due to the European Initiative for the Standardisation of Congestion Management and shortening of Lead Times with the Schedule Registration, the requirements to be satisfied by the involved partners have increased. To provide you with technical support in this regard, the employees of the 24/7 shift and the back office in Lehrte are at your disposal.

24/7 shift

The shift employees supports you with the following topics:

  • Coordination for the day ahead process
  • Intraday schedule changes
  • Congestion management

Back office

  • Day after process
  • General technical questions


The balance responsible party (BKV) registers the scheduled energy deliveries in a binding manner to the transmission grid operator by 14:30 on the previous day at the latest for the following day. You can obtain information on the schedules below

Information on a possible breakdown of the E-Mail-address of TenneTs scheduling system

In the case of longer  breakdown of the E-Mail-address of TenneT’s scheduling system fahrplan(at)tennet-scheduling.eu we will inform you as balance responsible party.

In such a case we ask you (as far as available) to use the communication via ISDN to our FTP-Server.
As a further alternative we might in such a case possibly install another E-Mail-address for scheduling and inform you accordingly. This may cause slight changes in your IT (e.g. change of E-Mail-address of TenneT).

Please note this information in order to enable you and your communication systems to be prepared in the best possible way for such a case.
