Bidirectional Austrian-Czech Interconnection

The project of the Bidirectional Austrian-Czech Interconnection (BACI) is a planned pipeline connection of the   Austrian and Czech gas transmission networks between the compressor stations Břeclav in the Czech Republic and Baumgarten in Austria, which would directly link the gas markets of both EU Member States for the first time.

The project is intended to efficiently secure transmission capacity between the two countries and to enable further market integration fostering the liquidity of gas trading places and gas-to-gas competition on gas wholesale markets in the Czech Republic and Austria for more reasonable gas prices, which can also affect neighbouring gas markets positively.

The projected length of the new pipeline (DN 800, PN 84) in the territory of the Czech Republic is 12 km. A final investment decision has not been taken. The partner to the project is the Austrian gas transmission system operator, Gas Connect Austria GmbH.

In accordance with Act No. 183/2006 Coll., on Land-Use Planning and Building Rules, the plan to execute the Bidirectional Austrian-Czech Interconnection project is included in the version of the Regional Development Policy of the Czech Republic as of 2008.

EU Regulation No. 347/2013, the main purpose of which is to facilitate and accelerate the implementation of projects of strategic importance in the energy sector, introduced, among other things, a new status for projects – Project of Common Interest (PCI). The PCI status can be awarded to projects that provide a significant contribution to creating the internal energy market, ensuring the security of supply, and building strategic priority corridors with a cross-border impact. The list of PCI projects is to be updated every two years. The Bidirectional Austrian-Czech Interconnection (BACI) project (as PCI No. 6.4) was included on the list of PCI projects in 2013, in 2015 and in 2017. In 2020, the project was not awarded the PCI status. Additional information on Projects of Common Interest (PCI) is available on the European Commission's website here, and on the PCI interactive map here.

Public consultation for the project held within the framework of projects proposed for inclusion on the list of Projects of Common Interest (PCI) took place between December 22, 2014 and March 31, 2015, and between March 27 and June 19, 2017. The past public consultation was conducted between February 26 and May 29, 2019. For additional information on the public consultation process, please, follow these links: 2015, 2017 and 2019.

In 2012, the European Commission allocated funds under the European Union program for Trans-European Energy Networks (TEN-E) to co-finance a project entitled "Study of the First Direct Bidirectional Czech-Austrian Interconnection". The co-financing concerned two main activities:

  • Update of documentation for the land-use permit application in conformity with new legislation – this task mainly concerns the technical specifications for the new route of the pipeline and the compilation of project documentation for the land-use permit application.
  • Study of potential future use of the Bidirectional Austrian-Czech Interconnection – the study dealt with technical and economic aspects of the project and included an analysis of its impact on the Central and Eastern European region.

The European Union trans-European Energy Networks program (TEN-E) supported long-term investments into the energy sector. The objective of the program was to ensure the security and diversification of supply, and more importantly, the gradual interconnection, interoperability, and development of trans-European networks for the transmission of electricity and transport of gas.


In 2014, the project was awarded a grant under the Connecting Europe Facility (CEF) program in the amount of 50% of total eligible costs for preparing background documents for the Investment Request application.

The Connecting Europe Facility (CEF) is one of the most important programs included in the EU financial framework for the years 2014-2020. The program consists of providing EU financial assistance to support Projects of Common Interest in transport, energy and telecommunications infrastructure, using the synergy potential between these sectors.

The pre-application procedure accordingly to the EU Regulation No. 347/2013 at the Ministry of Industry and Trade was completed.
