Invoice issuing specifications

Pursuant to § 15 EEG 2014, the grid operator in whose grid the cause for the necessity of the regulation lies, is obligated to compensate the affected system operator.

Liability for compensation

Information obligation 

Pursuant to the EEG, grid operators must inform plant operators about anticipated measures. TenneT publishes usage reports on feed-in management. The usage reports contain

  • the measure's ID  
  • the affected region subject to the feed-in management
  • the cause of the measure
  • the start and end of the measure 
  • the levels invoked as well as the start and end of the respectively invoked level.

Changes to 01.01.2020

Regulation (EU) 2019/943 of the European Parliament and of the Council of 5 June 2019 concerning the internal electricity market will enter into force on 1 January 2020. With regard to compensation payments for feed-in management measures, this leads to the following amendment based on the provisions of Article 13 (7) sentence 2 of the above-mentioned Regulation:

Compensation payments due to feed-in management measures are to be paid at 100%. The limitation of the amount of compensation to 95% of the lost revenue up to a limit of 1% of the annual revenue is not applicable.

We will apply this regulation accordingly for measures from 01.01.2020 onwards. However, this regulation is a contradiction to the "95% regulation" according to § 15 para. 1 EEG 2017. Until a legislative clarification and/or notification by the regulatory authority, the compensation payments will therefore be made at 100% subject to full recognition by the competent regulatory authority.

General advice

The amount of compensation payments is established in accordance with the current guideline of the German Federal Network Agency for EEG feed-in management.

Furthermore, the joint association recommendation “Determination of compensation payments pursuant to § 12 para 1 EEG 2009” put forth by the associations BDEW, VKU, BEE, BWE, Fachverband Biogas, BSW Solar, AGFW and IVG, last revised on 13-01-2012, must be observed.

Basically, the values of the billing-relevant measuring system must be taken into consideration when calculating the outage work, which is also used in the remuneration according to the EEG.

Background and important information

Important for issuing invoices / compensation payment

Invoices are to contain, among other things:

  • Information on the identification of the plant(s), i.e. identification of the asset key(s) and the metering point name.
  • Amount of the claim to compensation pursuant to § 16 EEG in conjunction with § 17 EEG 2012 at the time of the settlement, e.g. by a copy of a credit note from the connecting grid operator.
  • When using the balance due accounting process, the corresponding reference values and the power curve.
  • Information regarding additional or saved expenses caused by the EMM.

Furthermore, in the course of the examination of incoming invoices from the access network operator, the feed-in dates for the metering point (down to the quarter hour) and, if applicable, information as to whether and in what form of direct marketing pursuant to § 33 b EEG 2012 the plant uses, are made available. The load profiles must be transmitted as an Excel file to the mailbox eeg-kwkg@tennet.eu in electronic form. The corresponding metering point must be indicated in the header.

The calculation files must:

  1. be completely filled out, 
  2. be completely printed out, 
  3. be signed,
  4. be attached to the invoice as an appendix and
  5. be sent to the following address:

TenneT TSO GmbH / Abteilung FSC-GAP

Bernecker Straße 70

95448 Bayreuth

Background / instructions for filling out the calculation files

To reduce the effort required to determine of the amount of compensation, and to ensure the payment of this amount in a timely manner, TenneT makes available appropriate forms or calculation files.

The calculation files are available for download on this page. With these standardized calculation files, the compensation amount may be calculated on the basis of the published guidelines for EEG feed-in management of the German Federal Network Agency, last revised on 29-03-2011 (version 1.0).

The calculation files must be filled out completely. The mandatory information must be entered in the yellow highlighted cells. Optional information can be entered in the orange highlighted cells. The macros must be activated when opening each file.

Once all the data has been entered completely, the amount of compensation is determined by the program after you click on the “Calculate” button.

The calculation files are used for the standardized calculation of the compensation amount. Special cases may not be fully replicated and must be agreed upon in the particular case with TenneT.

The areas in the calculation files protected by passwords must not be changed; otherwise, TenneT reserves the right to reject the issued invoice and to undertake a legal test. A difference is made in accordance with EEG 2009 and EEG 2012 in the calculation files. For EMM until the end of 2011, please use the downloads under EEG 2009. For EMM beginning January 2012, the corresponding downloads are found under EEG 2012. 


TenneT reserves the right, particularly in the case of plants operated for combined heat and power generation, to have the amount of the compensation payment examined by an independent third-party expert (e.g. financial auditor). 

The compensation amount is paid with the reservation that the conditions required for this pursuant to EEG or KWK-G are present. 

If the information turns out to be unfounded in the context of the billing to TenneT TSO GmbH, TenneT TSO GmbH can demand an interest-bearing refund of paid compensation to the appropriate extent.
