When looking at how the volumes and costs have changed over the years, the new update in “Energy data compact” provides you with historical data and background information. This complements the existing data on congestion management. All the information on this topic can be seen by entering the search term ”congestion management”. Much of this data is available in a monthly format and is continuously updated. The data can be further broken down into federal state or energy source, for instance. Moreover, the network level at which the congestion occurs can be seen, such as whether it occurred in a domestic or cross-border network and, for example, whether it was current-related or voltage-related. All the data can be downloaded free of charge as graphics or tables and in various formats.
