Electricity supply interruptions in 2024 shorter than in the previous year – Germany’s electricity grid one of the most reliable in a European comparison
Year of issue 2025
Date of issue 2025.10.09
The Bundesnetzagentur has today published figures on interruptions to the electricity supply in 2024. The non-availability of electricity averaged 11.7 minutes per final customer. In 2023 it had been 12.8 minutes.
"The electricity supply in Germany is still very stable. The energy transition is making headway without any loss of reliable electricity supply,
" said Klaus Müller, President of the Bundesnetzagentur.
Even when taking energy transition measures into account, the figures on interruptions to the electricity supply in 2024 do not reflect any negative trends in terms of long-term interruptions. The current figure is below the level of the 10-year average (interruption duration of 12.7 minutes per final customer). A comparison with neighbouring countries also shows that Germany’s electricity grid remains one of Europe’s most reliable.
Bundesnetzagentur collects supply interruption data
Operators of energy supply networks report to the Bundesnetzagentur each year detailing all the supply interruptions lasting longer than three minutes that have occurred in their networks. The reports state the time, duration, extent and cause of the interruptions.
For 2024, 830 network operators reported a total of 164,645 supply interruptions at low and medium-voltage level. Thus the number of reports of interruptions has grown by around 6,300 compared with the previous year. Nevertheless, the average duration of an interruption in supply per final customer has reduced slightly and supply interruptions have been corrected faster.
The System Average Interruption Duration Index (SAIDIEnWG), calculated by the Bundesnetzagentur, shows the average duration of unplanned interruptions to supply per connected final customer and voltage level in a calendar year, not including those caused by force majeure (eg extreme events).
Figures for federal states and details of interruptions
An anonymised list of the individual supply interruptions reported has been published in addition to the SAIDIEnWG figures for each federal state.
An overview of electricity supply interruptions is available on the Bundesnetzagentur's website at www.bundesnetzagentur.de/SAIDI-Strom.
