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 49,1 minutes before the energy is flowing again.

Statistically speaking, in Berlin in 2017, every consumer spent approximately 18.3 minutes without electricity.1 For comparison: the same figure for Germany as a whole in 2016 was 12.8 minutes.2

Secure - laid underground, Berlin's electricity cables are 99.998% reliable


Global - the 34,707 km long electricity cables in Berlin would stretch once around the world

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 177.7 million euros on grid infrastructure in 2018, especially the expansion and maintenance of the distribution grid in Berlin. Nearly 70 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.


Surprising - Whitsunday is often the day of the year with the lowest energy consumption


Enduring - each year, Berlin consumes enough energy to run an ICE train non-stop for 200 years
