Milestones in our company history

We were founded in 1972 and are based in Vienna, Austria. Gas has been flowing through our TAG pipeline system since 1974. With 50 years of experience in the gas transport business, we have grown to become a vital European interconnector. Our modern pipeline system carries gas from Italy to Austria and our neighbouring countries, as well as in the reverse direction.

At approximately 380 km in length, our pipeline system is Austria’s longest high-pressure pipeline network. It comprises three parallel pipelines – TAG I, TAG II and TAG Loop 2. One of them will be converted to carry pure hydrogen by 2030.

transport services are our expertise


In everything we do, we make a significant contribution to security of supply in Europe.
We are one of Europe’s leading natural gas transporters. With our transport capacities and the services we offer, we are a dependable partner to the energy market. We provide our services transparently and in a non-discriminatory manner.

Who our customers are and how we work with them

Our customers are system users. By entering into a capacity contract with us, they acquire the right to enter natural gas (booked flow rate) at an entry point, or withdraw it at an exit point, on a guaranteed or interruptible basis.

System users allocate the capacities specified in their contracts to balance group representatives, which are authorised by law and under the general terms for balance group management to nominate those capacities for the relevant entry and exit points in accordance with the Austrian Gas Market Code.

Nominations are defined in terms of energy (kWh/h). Subject to the technical capacity of our pipeline system, we accept defined nominations for the Baumgarten entry point (Austrian/Slovakian border) and the Arnoldstein entry and exit point.

Quality and professionalism

To avoid interruptions and reductions in the flow of gas, we coordinate necessary maintenance work so as to minimise the impact on our transport services.

Gas accepted into our pipeline system must meet defined quality specifications. As a minimum, gas entering the TAG transport system must satisfy the criteria specified in the technical rules as defined in section 7 paragraph 1 no. 53 of the Austrian Natural Gas Act. These technical rules are listed in Annex 2 to the Gas Market Model Ordinance.


TAG Owners

Our jointly authorised owners are the Italian company Snam S.p.A.
and the Austrian company Gas Connect Austria GmbH.

Our policy for health, occupational safety, information security and environmental protection standards

HSSE Policy

At TAG GmbH, we are acutely aware of our responsibilities towards our employees, owners and interested members of the general public. We are committed to applying recognised standards in the fields of health, occupational safety, information security and environmental protection.

Our primary objectives are to reinforce positive effects, minimise negative impacts, and continually improve our performance. In pursuing these objectives, we live out our shared values of respect, responsibility and competence. These principles are the pillars of our corporate philosophy and guide our efforts to foster security and safety, and health and environmental awareness.


We oblige all parties who work for TAG GmbH to comply with our principles.

We consider health, occupational safety, information security and environmental protection as integral parts of our activities and our management culture.

We demand exemplary behaviour in relation to HSSE both from ourselves and from our partners. We are aware of our responsibilities to our wider environment and act accordingly.


We comply with all HSSE relevant laws, technical guidelines and other binding obligations.

We see HSSE as a shared responsibility and are confident that accidents and undesirable events can be prevented. Nevertheless, in case of an unexpected event we are prepared to minimise unwanted consequences and restore safe operation.

We take seriously the impacts of our activities on people, society, animals and the environ­ment. We aim to minimise energy use, limit the release of pollutants, reduce greenhouse gas emissions and protect sensitive information and information processing facilities. We strive to continuously and measurably improve our HSSE performance.


We are aware of our risks and opportunities and take specific state-of-the-art action in response.

We ensure that our employees are well trained. All our staff is involved in developing and implementing our HSSE programme.

We learn from mistakes and ensure that they never happen again. All our employees are required to report unplanned events and potential improvements. We review those events and circumstances systematically in a follow-up process and implement any lessons learned.

Our commitment to community projects and social organisations

Social responsibility

We get involved where help is needed, because human beings are important to us. In all our partnerships, we attach great importance to respect, responsibility and professionalism. These values are our corporate values and, as such, they form the basis for harmonious relationships both within our organisation and with the wider community.

Our collaboration with Österreichischer Buchklub

For years, we have worked successfully with Österreichischer Buchklub (Austrian Book Club), the country’s largest non-profit organisation dedicated to literacy. Book Club provides age-appropriate support for reading skills and language development in children and young people. It is not only schools that benefit from this partnership – we do too, because it enables us to give the communities situated along our pipelines an understanding of our company and our social responsibility.

“Reading for all the senses” audio drama project in schools

With a focus on STEM subjects (science, technology, engineering, and mathematics), this project entitled “Lesen für alle Sinne” also provides technical know-how about innovative methods for supporting the acquisition of reading skills. Together with Österreichischer Buchklub, we aim at raising awareness of how literacy is about much more than just practising reading. It is also about a whole range of other positive effects: dealing with specific topics and issues, awakening curiosity, reading aloud to one another, teamwork, discussion about texts and effective use of the voice.

At the end, participants devise and record the audio drama to produce a piece of work that can be listened to and shared again and again. We are grateful to Österreichischer Buchclub for its community engagement and look forward to working on further projects together.

Partnering successfully with Diakonie - a firm commitment to social justice

As one of the five largest social welfare organisations in Austria, Diakonie has over 600 locations nationwide. At TAG, we are proud to have partnered with Diakonie since 2020 and to work with it on important charitable projects.

During the COVID-19 pandemic, we established a COVID assistance fund to provide urgently needed assistance packages for families in poverty. We also provided hot meals for people suffering homelessness. In another major project, we set up a COVID testing station at AmberMed, Diakonie’s medical facility, which provides medical care to those without health insurance. We also supported Diakonie by providing important hygiene facilities and funding a part-time physician at AmberMed for one year.

As well as supporting Diakonie financially, we also wanted to help through direct action. So some of our staff members cooked for Diakonie’s volunteer helpers to thank them for their tireless efforts.

Thanks to our support, a qualified nurse joined the AmberMed team in January 2022.

We are proud to help provide healthcare to some of the most vulnerable members of our society and to work with Diakonie to ensure that no one goes without the medical assistance they need. Together, we are working to improve the help available for those in need.
