Connection in medium- or high-voltage

We require for the set up of a new connection:

• expected power requirements* (net output),
• a scaled site plan that includes the local position of the property to be connected: If you already have a suggested location for your transfer station, include this on the site plan along with the desired cable route through the property or building.

Please send also the completed forms E.1 and E.2.

If you are planning to change your own system, e.g. B. an extension or an adjustment of the connected load, please send us the completed forms E.1 and E.2 as well as a net ouput.

Please send us the completed form E.1 to decommission your transfer station and dismantle the connection.

For your request please use the following forms:

E.1 – Application
E.2 – Data sheet for assessment of system perturbations

Along with the quote for your connection to the medium-voltage grid, you will also receive one of the following versions of the grid connection contract:

1. If you use the connection yourself, you will receive a contract which regulates both the grid connection and connection usage

• Sample copy of contract regulating grid connection and connection usage (PDF 173 kB)

2. If your connection is used by a third-party, you, the power recipient,

• will receive a grid connection contract
  sample copy of grid connection contract (PDF 115 kB)
• and the connection user will receive a connection usage contract
  sample copy of connection usage contract (PDF 127 kB)

The contract also contains the following attachments:

• General specifications and technical requirements for grid connections and connection usage in the medium-voltage and high-voltage grids (PDF 184 kB)
• Property boundary (only applies to the grid connection contract and the combined grid connection/connection usage contract):
  Property boundary measuring field (PDF 94 kB)

Historically, in the case of existing connections, the following property boundaries are also conditionally available:

• Property boundary cable termination (PDF 93 kB)
• Property boundary bus bar branch (PDF 104 kB)
• Property boundary transfer control panel (PDF 94 kB)

Note: Further explanations regarding terms such as power recipient, connection user, grid connection contract and connection usage contract can be found in our glossary.

The set up or change of connections in the medium- and high-voltage grid takes place after 17 EnWG in connection with our „General and technical conditions for connection and connection use in the medium- and high-voltage grid“.

^{All documents in German language only.}

The technical requirements are to be taken into account when planning, constructing, connecting and operating customer systems connected to the medium-voltage grid.

Manufacturers of medium-voltage switch gears that are permitted to be installed in the distribution grid receive a corresponding certificate of approval from us before they are installed. If equipment from other manufacturers is installed, it must be checked and approved by the Distribution System Operator before use.

Overview of approved equipment:

• Approved factory-ready electricity stations (PDF 84 kB)
• Approved switchgear (PDF 81 kB)

The following manufacturers currently have permission to install approved switchgears in Berlin's medium-voltage grid:

As a Distribution System Operator, we keep a directory that contains a register of electricians who are permitted to construct, expand, alter or maintain the systems on our distribution grid. When choosing your electrician, please ensure that he or she is registered in our directory and has the necessary credentials.

The following guidelines apply to temporary connections and to the operation of a customer-owned station for providing power to a construction site with a transformer of up to 630 kVA:

Technical guidelines for stations for providing power to a construction site 2009 (PDF 322 kB)

If you require a temporary connected capacity greater than 630 kVA, our technical requirements apply. You will find the documents at 'Technical documents'

The application, planning and commissioning procedures and practices for stations for providing power to a construction site are identical to those that apply to an application for a transfer station connection.

At the moment, the individual connection costs are the only charge that applies to the connection of a station for providing power to a construction site. The connection of a station for providing power to a construction site does not currently require the customer to make a contribution towards building costs.

VDE-AR-N 4110 applies to the connection and operation of standby generators.

For planning, set-up, operation of and changes to customer installations (transformer stations and generation facilities) on the 110 kV high-voltage grid in Berlin, the technical requirements for the connection to the high-voltage grid (VDE-AR-N 4120^*) as well as the supplementary Berlin-specific technical requirements for connection to the high-voltage grid in Berlin, apply.

Further information

Since 1 January 2015, the VDE-AR-N 4120 has replaced the Transmission Code 2007 as well as the VDN guideline "Renewable Energy Power Plants on the High-voltage Network" (EEG-Anlagen am Hoch- und Höchstspannungsnetz) for 110 kV grid connections..

Information of the VDE on the topic of high-voltage connection

Note

Since May 2016, the "Commission Regulation (EU) 2016/631 of 14 April 2016 establishing a network code on requirements for grid connection of Generators" has applied. At present, this is being transposed into national law by the relevant bodies, such as the VDE-FNN, and we expect an amendment to the technical connection regulations (TAR).^*

^* The VDE-AR-N 4120 forms part of the VDE regulations and can be purchased from VDE Verlag GmbH.

Applicants for a grid connection request in accordance with the Power Station Grid Connection Ordinance (Kraftwerksnetzanschlussverordnung - KraftNAV) also use the documents from our requirements for connection to the high-voltage grid in Berlin.

Once the boundary conditions (including power requirements, location of the planned customer-owned transfer station and the cable route through the customer property) have been clarified, we will provide you with an individual quote for establishing a connection between your transfer station and our medium-voltage grid.
The quote also sets out the connection costs for the connection to our medium-voltage grid and a contribution to building costs.

The contribution to building costs is in line with the recommendations made by the Federal Network Agency. To establish this fee, the published unit price of the access grid level in force when the contract was concluded or adapted is multiplied by the contractually agreed provision of power:

Contribution to building costs = Annual unit price (≥ 2,500 h/a) of the grid level x appointed power (kVA)

• Federal Network Agency position paper on charging contributions to building costs for grid connections in the area of grid levels above low-voltage (BK 6p-06-003 dated 05/01/2009) (PDF 44 kB)
• Price sheets of grid usage fees

Note: Some connection versions and additional actions may entail extra costs which you must bear in addition to the costs of a regular connection.

Price sheet reactive energy

When withdrawal electrical energy, a displacement factor (cos Phi) between 0.9 inductive and 1 must always be observed. If this is not the case, no reactive work is calculated according to the following price sheets.
