Trans Austria Gasleitung Gmbh (TAG) is a leading Austrian gas transmission system operator (TSO) and an important partner for the Austrian and European gas supply and other grid-based renewable energy forms such as biogas and hydrogen.
Its core business is the transport of gas and the operation and maintenance of gas pipelines and facilities for the reliable and secure supply of energy to Austria and neighboring countries.
