Revenues from cross-border congestion management (2007 - 2022)

As of 1 January 2020 Regulation (EU) 2019/943 of the European Parliament and of the Council of 5 June 2019 on the internal market for electricity is applicable. According to this regulation Bundesnetzagentur shall annually by 1 March publish a report informing on the amount and use of the congestion revenues collected by the national transmission system operators (TSOs) in the previous calendar year.

In the past, pursuant to point 6.5 of the congestion management guidelines in annex I of the now repealed Regulation (EC) No 714/2009, the reporting comprised the time between 1 July until 30 June.

Study on the uniform price zone Germany-Austria (October 2011)

Publication of the study "Relevance of established national bidding areas for European power market integration – an approach to welfare oriented evaluation"

The debate on splitting up the single German-Austrian wholesale price zone threatens the intended network development and may be detrimental to competition in Germany and Europe. This is confirmed by a study on the relevance of established national bidding areas for European power market integration.

The study shows that the necessary preconditions are not in place for a splitting of the market Germany-Austria, because the situation in the network is not characterized by structural and sustained congestion. Moreover there is no indication that German TSOs shift internal congestion to their external borders.

Furthermore, there are a number potentially negative consequences from a market splitting: neither could a splitting result in an increase of cross-border capacities available to the market, nor would it reduce loop flows through neighbouring countries. On the contrary, splitting up the price zone would increase market power of large electricity generators to a degree not acceptable for viable and effective competition. Market splitting would also tend to have a negative effect on the network development, which is needed for the integration of electricity generated from renewable sources.

The implications of a market splitting go far beyond the German and Austrian market. The German-Austrian electricity market promotes the European integration process with its central location in the heart of Europe and its high liquidity.

"Strengthening the internal market can be achieved through integration rather than segregation. Therefore, we should think about the forming of larger cross-border market areas, rather than succumbing to particularism." (Matthias Kurth)

Report on the impact of the nuclear power moratorium on the transmission networks and security of supply (April 2011)

The Bundesnetzagentur was commissioned by the Federal Ministry of Economics and Technology (BMWi) to write a report entitled "Impact of the nuclear power moratorium on the transmission networks and security of supply". The report was submitted to the BMWi on 12 April 2011. This was an initial, preliminary assessment by the Bundesnetzagentur based on statements by the transmission system operators.

Publication of the first regional report on electricity interconnections management (March 2010)

The regulators of the Central-west region (CWE) have published their first regional report on electricity interconnections management and use 2008, which provides a detailed evaluation of the economic efficiency of congestion management methods at a regional level.

The report should help market parties to get a better understanding of the effectiveness and efficiency of congestion management methods. Therefore, regulators of the CWE region welcome any comments interested parties could provide, as regards to the methodology and the content of the report as well as on the conclusion to be drawn from it.

The report has been published on the website of the European Energy Regulators and can be found via the following link.

Report on the capacity auction at the French-German cross-border interconnections in 2006

Together with the French regulatory authority Commission de Régulation de l' Énergie, the Federal Network Agency provides a report on the capacity auction at the French-German interconnections in 2006, in line with the common roadmap. This report describes the effects of the changes in the capacity allocation mechanisms since the beginning of 2005 and points out further possibilities for improvement.

Open Market Coupling (2006)

Studies confirm feasibility and positive effects of the OMC.

In the framework of the European discussion on the improved and market based allocation of cross border capacities the concept of the Open Market Coupling has been developed and introduced by the German Power Exchange EEX in the first round of the Mini Fora. The concept envisages a combination of explicit and implicit auctions when allocating the transmission capacity between liquid European markets.

According to the concept a central Auction Office will be established or an existing Auction Office’s functions are extended. The Auction Office bids at all participating power exchanges, enters in the rights of use of allocated capacity and manages the electricity cross border trade.

The German Study Group on Congestion Management commissioned three studies on this concept.

The first study (leading consultant Prof. Dr. Jürgen Kühling) deals with the examination of legal on the implementation of the OMC. The second study (RWTH Aachen, leading consultant Prof. Dr.-Ing. Hans-Jürgen Haubrich) examines technical conditions for the functioning of the OMC. The third study (Frontier Economics/ Consentec/ IAEW) provides an assessment of different congestion management methods on economical aspects.

Below the English translation of the summary of the legal study and English translations of the technical and economical studies are available. The Federal Network Agency has commissioned the translations of the economical study. Therefore the translation of the study is not authorized through the consultants.
