Bonn (dpa) - Emergency interventions to stabilize the power supply in Germany also cost billions in the past year.
Around 1.4 billion euros were incurred for network and system security measures, according to figures from the Federal Network Agency.
That was around 100 million euros more than in 2019. The costs are allocated to the electricity price via the network charges and ultimately end up with the consumer.
These costs are caused by the insufficient expansion of the electricity grids in Germany.
If a lot of wind power is generated in the north, there are always bottlenecks in the transport of electricity to southern Germany.
The transmission system operators then reduce the feed-in of electricity from conventional power plants in the north and increase it in the south.
If that is not enough, wind turbines must also reduce their output.

Last year, a good 6100 gigawatt hours of electricity from renewable energies could not be used.
That was around 3 percent of total renewable generation in Germany.
The operators of the plants, especially wind turbines in Schleswig-Holstein and Lower Saxony as well as in the North and Baltic Seas, received compensation totaling 761 million euros.
The costs of reducing and increasing the feed-in of conventional power plants and maintaining reserve power plants amounted to a good 637 million euros.
