In accordance with Section 13 (1) EnWG, the transmission system operators (TSOs) are obliged, among other things, to carry out measures in accordance with Section 13a (1) EnWG (redispatch). The redispatch processing server (RAS) is used to process these measures. The harmonized activation process (HAP) was developed by the TSOs in 2019 for coordination with the parties responsible for scheduling (EIV). The HAP replaces telephone coordination and the RD order process in order to accommodate the constantly growing number of participants in the redispatch process. With the HAP, the redispatch is called up by exchanging XML files based on the ENTSO-E formats. The following process diagram illustrates the coordination process. There are also supporting processes that ensure secure operation. The TSOs intend to successively implement the HAP with all affected market participants.
To participate in the HAP, the EIV requires software that can process the files and send the corresponding responses back to the TSO. The TSOs provide the RACE - Redispatch Activation Client for this purpose. This application is free of charge for the EIV. Further information on this can be found below. However, an EIV is also free to configure its own solution for the coordination processes. The EIV is then responsible for the proper functioning of its own software solutions. The process description and the attached format descriptions and examples therefore need to be taken into account. These can also be found below. Commissioning for EIVs always takes place in consultation with the connecting TSO and is accompanied by extensive integration and technical tests. The TSOs recommend the use of the RACE. This has already been successfully tested operationally with a large number of EIVs. In addition, further developments and adaptations are covered by the TSOs.
