Grid re­serve / re­serve pow­er plant re­quire­ment

The Netzreserveverordnung (NetzResV) stipulates that the transmission system operators (TSOs) are to carry out a system analysis every year to determine the reserve power plant capacity necessary for future grid stabilisation using redispatch. The Bundesnetzagentur examines the system analysis and publishes its report on the need for reserve generation capacity every year.

Latest Bundesnetzagentur report and the TSOs' system analysis

The latest report of 28 April 2021 deals with the need for reserve power plants for the 2021/2022 winter and the year 2023/2024.

  • The requirement for winter 2021/2022 amounts to 5,670 MW.
  • The 2023/2024 period has also a total requirement of 4,169 MW.

The grid reserve requirement can be met in the coming winter half-year from domestic grid reserve power plants. The procurement of additional grid reserve power from foreign power plants is therefore not required.
