Call for expressions of interest in accordance with § 4 para 2 of the German Regulation on Network Reserve (NetzResV) for the winter period 2025/2026 (1st October 2025 - 31st March 2026)
In accordance with the provisions of the German regulation on network reserve of power plants (Netzreserveverordnung) as last amended on December 22nd 2023, the German national regulatory authority (Bundesnetzagentur, NRA) has examined the requirement for additional reserve power for the network reserve as determined by the German transmission system operators for the winter period 2025/2026, and has published the associated report in accordance with § 3 para 1 NetzResV.
In the report of the German NRA dated April 28th, 2025, an additional demand for generation capacity for the network reserve in the total amount of 1344 MW is determined for the winter term 2025/2026, for the coverage of which an expression of interest pursuant to §4 NetzResV is initially launched. The total amount of network reserve capacity to be acquired may change depending on the sensitivity to network congestions and has to be evaluated in the context of possible alternatives within the congestion management as well as the current political situation.
The German transmission system operators hereby invite interested power plant operators to submit expressions of interest in accordance with § 4 (2) NetzResV for the participation of their power plants in the network reserve in the period from 5th May 2025 to 19th May 2025 10 a.m. CET. To submit an expression of interest, interested operators are required to complete the documents supplied for this purpose and return send them electronically to the responsible transmission.
