Germany has four balancing responsible TSOs and more than 800 DSOs. Hence, the publication of hosting capacity information is dependent on the SO responsible for the specific area of the grid.
At the TSO level, 50Hertz publishes a table indicating the amount of additional feed-in and additional load that can be hosted at the existing substations within its control zone. In addition, an assessment of switchgear bay availability is provided, based on already occupied and requested bays.
Amprion publishes the availability of switchgear bays in its control zone. Substations with free switchgear bays and potentially expansions for additional switchgear bays are indicated, as well as an initial assessment of expected commissioning years.
TenneT TSO provides a map of its control zone that shows currently published locations of possible new connections. It is accompanied by a table with an indicative location of the substation and an estimated in-service-date of new customer connections together with possible comments on local limitations.
TransnetBW provides a map indicating substations with general or limited suitability for new grid connections in its control zone.
At the DSO level, information on available connection capacity is provided by a number of regional DSOs. An example from the participating company Netze BW GmbH is presented."Mittelspannungsauskunft" is an internet-based self-assessment tool for those wishing to feed in electricity about available connection capacities in the MV grid. The hosting capacity system calculates the capacity based online loading, transformer loading, absolute voltage, and voltage increase. In the future, there may possibly be an information service for supply and storage systems.
