In Germany, the Redispatch process controls the use of generation plants and prevents the supply of energy from these plants from causing bottlenecks in the power network. For this purpose, a network operator corrects the previously planned use of the generation plant by the operator.

Basis for Redispatch 2.0

Changes within the framework of the Network Expansion Acceleration Act (NABEG 2.0), which came into force in May 2019, have resulted in amendments to the Energy Industry Act (EnWG). The previous requirements for feed-in management in accordance with the Renewable Energies Act (EEG) and the Combined Heat and Power Generation Act (KWKG) will be repealed and transferred to a uniform Redispatch regime (Redispatch 2.0) in accordance with Sections 13, 13a, 14 of the Energy Industry Act (EnWG). Redispatch 2.0 is to be implemented from 1 October 2021 and currently affects all generation and storage plants with an output from 100 kW upwards. This results in new requirements for all market partners. The previous feed-in management is to be largely replaced.

The new process

In the previous process, only large conventional power plants participated in the Redispatch process. Generation plants for renewable energies were not initially taken into account. As the renewable energies plants are being significantly expanded as part of the energy transition and are now providing the majority of electricity generation, they are increasingly causing bottlenecks in the electricity network and must therefore be regulated by the network operators in the short term. In order to keep the curtailment of renewable energies to a minimum in the future, the renewable energies plants are to be taken into account in deployment planning to the same extent as conventional power plants and included in the Redispatch process.

The network operators have created the new Redispatch 2.0 process for this purpose. The process ensures the exchange of data between network operators in Germany for all power generation plants of 100 kW and upwards and ensures that, in the event of bottlenecks, only the most cost-effective generation plants, which are the most effective for eliminating bottlenecks, need to adjust their output.

Basic procedure

The key process steps of Redispatch 2.0, application guides, the introduction scenario and definitions of terms, were drawn up in the Bundesverband der Energie- und Wasserwirtschaft e.V. (Federal Association of Energy and Water Industry - BDEW) and are available on the BDEW website.

There are also various specifications from the Federal Network Agency for the new Redispatch process:

Participants in Redispatch 2.0

In general, the new process affects all plant operators with generation plants from 100 kW and above installed output (including emergency power generators) and all power network operators in Germany whose network these plants are connected to.

Our implementation

We identify all plant operators and plants with an output of 100 kW or more and contact the plant operators before the process starts. The procedure for each plant is coordinated and all plants receive a unique ID. The plant operators are obliged to provide information about the affected plants.
