The German regulator Bundesnetzagentur (BNetzA) has determined the approval of an overbooking and buy-back system of the Transmission System Operators (TSO) for the offering of additional capacities in the nationwide market area (BK7-19/037 – „KAP+“) on March 25, 2020. It was published at the beginning of April 2020.
Since May 2019, TSO, BNetzA and further market participants, especially involved in the different consultation processes, have executed an intensive coordination process. In this context, the TSO published a concept concerning the overbooking and buy-back system as well as a detailed process description. Both documents are elements of the ruling. In addition, the TSO and the market area managers (MAM) have discussed the concept and the process description with the market participants and clarified the essential considerations.
With regard to the operational execution, the basics, which are places through Kap+, have to be amended through specifications of the process description from time to time. The first specification was executed in April 2020 by TSO and MAM. The document is available for download below. The performed specifications affect the handling of interruptible internal orders (number 2.2.2) as well as the design of the capacity buy-back process (number 2.3.4 and 22.214.171.124). Both constitute through Kap+ covered specifications from the point of view of BNetzA. Further potential necessary itemisations and specifications of the process description will be communicated in a comparable manner.
