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 30 April 2019 deals with the need for reserve power plants for the 2019/2020 winter and the year 2022/2023.
- The requirement for winter 2019/2020 amounts to 5,126 MW.
- The 2022/2023 period has also a total requirement of 10,647 MW.
The calculation of this requirement was made without taking into account the recommendation of the Commission "Growth, Structural Change and Employment" of 26.01.2019, to reduce the power of coal-fired plants to around 15 GW of lignite and about 15 GW of hard coal in 2022.
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.
