The smart electricity grid is...
Around 2.3 million Berlin households and businesses are supplied through our electricity grid. They use around 14 billion kilowatt hours - as much electricity as an ICE train would need to drive non-stop for 200 years. In order to maintain and modernise the grid, and equip it with smart technology, we invest in the hundreds of millions every year.
To ensure that the grid functions smoothly, we are decking it out with smart management technology and, at the same time, making it one of the smartest metropolitan grids in Europe. Additional technology enables central monitoring and management from the grid headquarters. The key advantage of this is that if an outage occurs, staff can respond quickly and redirect the electricity to other supply paths. In this way, outage times can be further reduced.
A milestone in our grid expansion is happening in the Charlottenburg district. Here, the largest investment project in Stromnetz's history is getting underway: in one of the most densely populated areas of Berlin, a highly modern grid node is being built for 72 million euros in a new building with new high voltage and control technology.
Europacity is being developed right next to Berlin's central station. This area will draw electricity from its own 110/10 kilovolt substation on Sellerstrasse. Stromnetz Berlin is investing over 30 million euros in the project as a whole.
A secure energy supply also requires new, modern technology. The current substation and its switchgears and transformers have reached the end of their useful life. Building the new substation guarantees a high quality of supply for a total of nearly 64,700 households and 3500 industrial and business customers in the Wuhletal area for the long term.
The very visible overhead cables in the Berlin area are being replaced in stages with underground high voltage cables. In the west of Berlin, all the high voltage overhead cables have already been removed. Positive side effects of the removal include higher transmission performance from the cable systems and a more attractive cityscape. Stromnetz Berlin GmbH's aim is to supply the city with electrical energy without any high voltage masts by 2030.
Over the next two years, we will be reinforcing the medium and low voltage grid in certain areas. The necessary renovation work will cost around 38 million euros. We have already started building work in the Hohenschönhausen, Mahlsdorf and Britz areas, and other districts will follow. The requirement was identified thanks to our state-of-the-art cable diagnosis management tool.
