Low voltage grid connection documentation
TAB NS Nord 2019
The "Technical requirements for low voltage grid connections (TAB NS Nord 2019)" ("Technischen Anschlussbedingungen für den Anschluss an das Niederspannungsnetz (TAB NS Nord 2019)") define the basic requirements of the distribution system operator with regard to the house connection, customer system and system operation. The system operator agrees to comply with these requirements.

Planning aid for charging infrastructure
To set up a charging infrastructure, the power requirement must be determined. If several charging points are planned, a simultaneity factor must be taken into account when determining.
To determine the individual power requirement, use the specifications in the technical connection conditions. In addition, we provide you with two alternative planning aids.
