Your guide to consumer installations subject to notification or authorisation
You can submit registrations or, where applicable, notifications for consumption installations – such as charging points, heat pumps, air-conditioning systems, electric heat generators or other consumption installations (including those covered by Section 14a of the Energy Industry Act (EnWG)) – via our service portal. This also applies to registrations for extensions to these installations. Please ensure you have the necessary documents ready in advance. Please do not forget to apply for a change to your grid connection if the agreed connected load changes as a result of the new consumer installations. This can also be done in a separate process via the service portal. However, a total of further documents are required for both processes, which we have compiled for you in a comprehensive overview.
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
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)
- 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.
Your path to a decentralised generation plant
Upon receiving a feed-in commitment, capacity is reserved for you on a binding basis; this capacity is then no longer available to other connection applicants. To prevent unnecessary capacity from being tied up, we have introduced the following reservation procedure. You can submit any supporting documents you already have from the reservation procedure directly with your application.
You can register a solar PV system, a storage unit or a combined heat and power (CHP) unit for your home, business or property via our service portal – as well as register any extensions to these systems. Please ensure you have the necessary documents ready in advance.
