Professional property connections

Documents for amendments or new applications for grid connections

Site plan, scale 1:500 or 1:1,000, showing:

• Parcel boundaries
• Building outlines (for blocks of flats and terraced houses, the boundary lines between individual buildings must be shown on the site plan)
• Service room or connection column (on the street side) or, in the case of medium-voltage connections, the desired location of the customer’s own transformer station
• House numbers
• Street names
• North arrow
• Location of any registered generation plant
• Location of charging points
  

If the property connection is located inside the building: floor plan of the ground floor and, if applicable, the basement, scale 1:100 or 1:50, showing:

• Parcel boundaries
• Building floor plan
• Service connection room (facing the street)
• House numbers (if there are several buildings)
• Street names
• North arrow
  

If available, sectional drawing, scale 1:100 or 1:50

If available, open space layout plan, scale max. 1:200

If you are not the landowner or the holder of a leasehold, a declaration from the landowner

• Low voltage
• Medium voltage
  

Further documents required for changes to or new applications for grid connections, as well as generation and consumption facilities

If you are acting on behalf of another party, you will need a corresponding power of attorney

For low-voltage applications:

• where applicable, forms in accordance with DIN-VDE-AR-N 4100, Annex B
• Where applicable, Form F.4 in accordance with DIN-VDE-AR-N 4105
  

For medium-voltage registrations:

• Supply facility/grid connection
  • E.1 and E.2
• Feed-in installation
  • E.1 and E.8 (pages 1(5), 3(5), 4(5) and 5(5) for the signature line)
• Mixing plants and storage facilities
  • E.1, E.2 and E.8 (pages 1(5), 3(5), 4(5) and 5(5) for the signature line)
    

If you are unsure whether you require a medium-voltage connection or not, please complete the forms for medium-voltage registration for connected loads of 250 kW or more. This is the maximum value at which a medium-voltage connection is generally required at the latest. However, depending on the grid topology, a medium-voltage connection may also be required for lower connected loads. You will then receive further information on this once the grid connection assessment has been completed.
