Our key tasks

We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).

Financial equilibrium

The financial equilibrium of TenneT TSO GmbH is reflecting the relevant efforts for the establishment of a balanced current account and the proceeds from the re-charging of the provided balancing energy to the balancing group managers.

With the following table, the financial equilibrium of TenneT TSO GmbH is depicted, reflecting the relevant efforts for the establishment of a balanced current account and the proceeds from the re-charging of the provided balancing energy to the balancing group managers. It does not contain expenses for balancing power financed through the grid charges.The given values (in €) represent the monthly costs for the balancing energy used by the TSOs to balance the balancing groups, the monthly revenues from the corresponding balancing group billing, the transfer of revenues for reducing the grid charges, as well as the offsetting with the delta account. The transfer of revenues ensues as of 01.12.2012, in accordance with the Resolution BK6 -12-024  of the Federal Network Agency, and the document "Model for calculating the reBAP as of 01.12.2012“ provides a detailed explanation of this. The delta account takes into consideration a correction amount from the past which, e.g. results from subsequent claims from balancing energy suppliers and which could not yet be clarified at the time of reBAP publication.

The balance results from:

  • Costs for balancing energy
  • Revenues from the balancing group billing
  • Transfer of revenues for NNI reduction
  • Offsetting with the delta account

The values are supplemented monthly with a time offset of three months.
