E-Bridge supports network operator cooperation Connect+

A new standard process for congestion management in power grids (Redispatch 2.0) will start in October 2021. As of July 1, the network operator cooperation Connect+ will provide a nationwide solution for data exchange free of charge. E-Bridge has supported this important project from the beginning as project manager in all phases.

The legislator stipulates that congestion management will be coordinated between all market participants and network operators in the future. Up to now, only large power plants were used for this purpose at the request of the transmission system operators.

From October 1, 2021, all plants larger than 100 kW, and thus also renewables, will be included in this process. As a result, distribution system operators will also assume an active role in congestion management in the future. “Redispatch 2.0 will also integrate renewables into congestion management in the future. With the help of this new standard process, congestion management will be optimized. The aim is to slow down the rise in costs. This will be made possible not least by the exchange of data via Connect+,” says Jörg Brand from Westnetz.

In the “Redispatch 2.0” project, the German Association of Energy and Water Industries (BDEW) has developed an industry solution for this purpose. The Federal Network Agency (BNetzA) has issued the main specifications.

In Redispatch 2.0, network operators in the transmission and distribution networks must coordinate intensively and exchange significantly more data with each other and with market participants in the future. For this reason, the Connect+ cooperation offers market participants a standardized communication channel as a single point of contact. The cooperation is open to further network operators, feedback and cooperation with market participants is also possible via the already existing consultation circles. In the conception and development phase to date, a Germany-wide standardized interface for the future exchange of redispatch data has been created. “This builds the foundation for the implementation of the roll-out scenario required by the BNetzA in the third quarter of 2021 for Redispatch 2.0 and the basic data exchange between market parties and network operators as well as the nationwide implementation of the new market role Data Provider can begin,” says Frank Reyer of Amprion.

The use of the RAIDA data exchange platform is free of charge. RAIDA was developed by the cooperation partners together with the IT service provider Soptim AG from an already existing IT system of Amprion. In the cooperation, tasks are distributed among several partners. For example, Amprion and Westnetz are responsible for hosting, while EWE NETZ is responsible for application management. “After a test phase of several months, RAIDA will already be operationally usable at the beginning of the implementation phase for Redispatch 2.0 on July 1, 2021,” says Elfried Dieling of EWE NETZ. “That’s why all network operators, deployment managers, plant operators as well as direct marketers are invited to support us in introducing the processes so that Redispatch 2.0 can be implemented in compliance with the rules.” Registration for the use of RAIDA already started on 28.06.2021 via the website www.raida.de.

“Especially in view of the dynamic framework conditions and the high time pressure, it was a special challenge to sharpen the scope of the TSO project towards a comprehensive Redispatch 2.0 data exchange platform,” says Nikolaus Pleister from EWE NETZ. “With the basis now created, the cooperation still has a lot of potential to master further challenges in the course of the energy transition,” adds Frederik Obinger from TenneT.
