Tender Control Reserve

background

Product tendering

As a transmission system operator, TransnetBW GmbH is responsible for the safe and stable operation of its grid. The condition for this is that the balance between production and use is maintained in the TransnetBW control area. In order to ensure this, TransnetBW GmbH needs control power and control energy. The products necessary for the TransnetBW control area are tendered by TransnetBW GmbH.

According to the new regulations of the second Energy Industry Act and the Network Charges Ordinance, the control reserve is tendered and allocated jointly by the German transmission system operators (TSOs). Further information is available on the shared website of the German TSOs.

Transnational cooperation

Study explores potential benefits

Transmission system operators from Belgium, Germany and the Netherlands conducted a study to qualitatively assess a joint coordinated balancing area (CoBA) in collaboration with E-Bridge Consulting GmbH and the IFHT Institute for High Voltage Engineering RWTH Aachen.

The aim of this was to analyse the regulatory and legal framework, the product specifications in the markets for system services and the overall market design in order to assess the potential benefits of a transnational reserve market.

The results demonstrate that the less complex cooperation options have been put into practice to a certain extent. Additionally, the study illustrates that the design of the existing markets with regard to secondary control and minute reserve varies significantly between the three countries. The introduction of transnational reserve markets stipulated by the Network Code on Electricity Balancing requires complex solutions.

Against this backdrop, the decision was made to initially explore the less complex options for cooperation:

  • Joint access to minute reserve
  • Belgium’s involvement in the joint tendering platform for primary control reserve
  • Increase in the permissible exchange of primary operating reserve between Germany and the Netherlands

Further analyses of cooperation options in relation to more complex reserve products (secondary control and minute reserve) are planned.

In contrast to the previously published study on transnational cooperation in the reserve market between Belgium and the Netherlands, this report includes an updated data set.
