Facts, figures and dates
Here we have put together an overview of the key facts, figures and dates on our company, our work and the city of Berlin. You can find the collated information as a fact sheet in the download area.
Stromnetz Berlin offers a high level of supply reliability: Statistically, each Berlin resident will only lose their power supply once every five years. If there is an outage, however, a disruption on the medium voltage grid will last an average of 48 minutes before the energy is flowing again.
Statistically speaking, in Berlin in 2019, every consumer spent approximately 34.6 minutes7 without electricity.1 For comparison: the same figure for Germany as a whole in 2018 was 13.9 minutes.2

In the metropolis on the Spree, 98 per cent of cables are underground. This means that they are well protected against external influences such as bad weather or lightning, although they can be damaged by underground building work.
Stromnetz Berlin GmbH will invest around 211 million euros on grid infrastructure in 2020, especially the expansion and maintenance of the distribution grid in Berlin. Nearly 60 per cent of this expenditure is going to companies from the Berlin-Brandenburg region. And that is still the case, even though all commissions over 400,000 euros are tendered across Europe.

7 Explanation: On February 19, 2019, there was an extraordinary, more than 31-hour, large-scale power failure in Berlin-Köpenick with around 34,000 network customers affected, this means commerce and households. The cause was a horizontal earth drilling during bridge construction work on the Salvador Allende Bridge. Both 110 kV feeder cables for the substation Landjäger were damaged. For comparison value SAIDI of 2018 for Stromnetz Berlin: 13.9 minutes.
