We provide installers, consultancy firms and other interested agencies with a comprehensive reference manual for the installation and operation of electrical systems connected to our distribution network.
Technical information on connections to the distribution network
Low voltage grid connection documentation
TAB NS Nord
The "Technical requirements for low voltage grid connections (TAB NS Nord 2023 v2.0)" ("Technischen Anschlussbedingungen für den Anschluss an das Niederspannungsnetz (TAB NS Nord 2023 v2.0)") 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.

Low Voltage Connection Ordinance
Further information on grid connection can be found in the Low Voltage Connection Ordinance (Niederspannungsanschlussverordnung - NAV).
All documents in German language only.
Medium voltage grid connection documentation
You find all documents on the Connection medium and high voltage page.
Documents on measurement and control
Our measurement and control concepts support you in integrating your energy system into our distribution network in a safe, standard-compliant and future-proof manner. The following documents contain important information on selecting and implementing the right concept for measurement and control.
Generating units connection documentation
You can find all the information and documents on the page generation units and storages.
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.
