Bundesnetzagentur publishes electricity security monitoring 2025

The Bundesnetzagentur published its report on the status and development of security of supply in the electricity sector, adopted by the German federal government on 2025-09-03.

• Main announcement: The monitoring analyses developments up to 2035 and examines two scenarios (a target scenario and a “delayed energy transition”). It finds Germany will need up to 22.4 GW (target scenario) or up to 35.5 GW (delayed transition) of additional controllable capacity by 2035; the agency supports a capacity mechanism, the federal Power Station Strategy, and the planned legal framework for additional power stations to be installed by 2030.
• Background and details: The report emphasises demand flexibility from heat pumps, storage, electric vehicles and electrolysers, and industrial load flexibility; notes that battery storage can already be refinanced on the market; warns that delays in renewable rollout and network expansion increase reliance on additional reserves and redispatch measures. The monitoring’s capacity needs broadly align with the 2022 monitoring (previous estimate 17–21 GW by 2030).
