Stromnetz Berlin fact sheet
In German language only.
Facts, figures and dates
We have put together an overview of the key facts, figures and dates on our company, our work and the city of Berlin.
Statistically, each Berlin resident will only lose their power supply once every four years. If there is an outage, however, a disruption will last an average of 48 minutes before the energy is flowing again.
Statistically speaking, in Berlin in 2021, every consumer spent approximately 9.4 minutes without electricity.1 For comparison: the same figure for Germany as a whole in 2020 was 10.7 minutes.2

In the metropolis on the Spree, 99 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 291 million euros5 on grid infrastructure in 2022, 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 430,000 euros are tendered across Europe.

There is a clear trend recognisable in Berlin, which will continue to increase over the next few years: alongside traditional electricity plants and CHPs, an increasing number of small, local generation plants are being integrated into our distribution grid. These include photovoltaic plants, wind turbines, thermal power stations in a wide range of sizes and bioenergy plants.
This trend can also be seen in tenant power systems, where in most cases CHP units are used to generate energy.
The photovoltaic plants and wind turbines represent a particular challenge for us: they do not produce a constant supply of energy. The time at which generation occurs and the amount of energy generated depend on how the wind is blowing and the sun is shining. However, there are also several smaller local generation plants, e.g. small thermal power stations, which feed in regardless of actual demand.
