Grid connection

Are you interested in connecting your plant(s) to our transmission grid? We have compiled relevant information and documents for you below. 

To maintain the technical safety of the transmission grid of Austrian Power Grid AG (APG), connections to APG’s grid are only permissible in compliance with the officially approved General Grid Conditions.

In addition to the direct statutory and regulatory requirements, the General Grid Conditions also regulate the underlying legal relationship between APG and its partners with respect to grid connection and grid use.

• Information sheet on the amendment of the General Network Terms and Conditions (German only)

• General Grid Conditions OLD - valid until 31 October 2024

   

• General Grid Terms and Conditions NEW - valid from 1st April 2025 (german only)

The price sheet (German only) regarding the system usage charges is also part of the General Network Terms and Conditions. The fee that APG is entitled to charge in accordance with the General Network Terms and Conditions in the event of violations of the agreed reactive power range is listed in the reactive power price sheet (German only).

Pursuant to Section  44 (1) Electricity Act (Elektrizitätswirtschafts- und -organisationsgesetz, ElWOG), the right to connect to the grid within an area covered by the distribution network essentially lies with the distribution system operators. A direct connection to APG’s transmission grid is possible if the relevant distribution system operator waives this right. Exceptions to this rule are installations with a grid connection of over 110 kV; however, in these cases a minimum capacity of 200 MW is stipulated in accordance with Section 55 (7) 5 Electricity Act (ElWOG).  

The establishment of a new grid connection or modification of an existing grid connection at APG must be applied for using the forms provided for these purposes. Modification of an existing grid connection includes, in particular, changes in the electrical properties of the grid connection in terms of the applicable technical rules, as well as changes in the grid use (e.g. planned increase in maximum capacity). The application should be accompanied by the necessary documents and evidence required for the assessment of the grid connection. The application and documents should be submitted together in writing to APG.  

Applications to APG shall be made in writing and signed in the company’s name, either by registered post (the date of receipt is determined by the incoming poststamp), or electronically by e-mail to the P.O. Box disclosed by APG. 

Application forms 

• Producers (German only)

• Consumers (customers) (German only)

• Distribution network operators (German only)

• Owners of interconnectors pursuant to Art 63 Regulation (EU) 2019/943 (German only)

Once the application has been received, APG will check it for completeness and the grid connection procedure will be initiated in accordance with the General Grid Conditions. 

During the review of the application, APG may ask the applicant to provide other necessary documents and evidence to make a detailed assessment of the grid connection. In the event of an incomplete and/or erroneous application, APG shall request that the applicant rectify the application within a reasonable deadline. 

In accordance with the deadlines specified in the General Grid Conditions, APG shall send the applicant a response, informing the applicant whether or under which conditions a grid connection can be made. The conditions may be manifold and may also include the possibility of restricted grid usage in certain circumstances. If the applicant does not oppose the conditions specified within the stipulated deadlines, these conditions shall be deemed accepted and further steps will follow. All conditions stated in the response letter shall subsequently be taken into account in the contracts to be concluded bilaterally. 

For the connection of new or significantly modified (in terms of the applicable technical rules) existing facilities to APG’s transmission grid, the requirements of the operational notification procedure and evidence of compliance in accordance with the details published by APG based on the applicable technical rules shall be complied with: 

• Operational notification procedure and evidence of compliance for power-generating modules in accordance with Network Code Requirements for Generators (NC RfG) (german only)

• Operational notification procedure and evidence of compliance for grids and loads in accordance with Network Code on Demand Connection (NC DCC) (german only)

In the course of the type-approval procedure, the applicant shall demonstrate to APG that their facilities meet the requirements of the applicable technical rules and the contractually agreed requirements.

Compliance monitoring of facilities that have already obtained the final operational notification is carried out annually by means of a questionnaire. The completed form for the respective year must be submitted to APG by the deadline of June 30 of the following year.
