Berlin's 110 kV distribution network is undergoing a high level of replacement and expansion of grid nodes and improvements to the condition of the grid, in response to the increased rate of approaching change in the generation situation and demands on the grid.
On the grid, we can see an increase in decentralised generation in the LV and MV areas and in the growth of the city. In the 110 kV grid, the changes are primarily due to additions and reductions in plant performance in various areas of the grid. The work to expand and reinforce the grid reflects the need for the provision of a safe supply even during periods of restructuring.
Although electricity consumption in the city is stagnating, the number of new connections and changes to the grid is constantly rising. It therefore appears that we can expect an increase in the load for the city. In addition, it is difficult to evaluate changes due to the impact of power-to-heat and additional e-mobility.
The various new-build substations are helping to replace old technology, as well as providing increasing automation.
Currently there are no grid bottlenecks in the high-voltage parts of the Berlin electricity grid.
