Core offering

TAG GmbH operates Austria's longest high-pressure natural gas transmission pipeline network (~380 km route / 1,140 km total across three parallel lines TAG I, TAG II, and TAG Loop 2) between Baumgarten (Slovak-Austrian border) and Arnoldstein (Austrian-Italian border), supported by five compressor stations with ~420 MW installed power and bidirectional flow capability. The company sells regulated gas transportation capacity to shippers and balance group representatives through primary market auctions and secondary market trading on the PRISMA European Capacity Platform, plus dispatching, contracting, and tariff calculation services. TAG is converting 380 km of pipeline for pure hydrogen transport (H2 Readiness, 168 GWh/day capacity) as part of the European Hydrogen Backbone and SoutH2 Corridor.

Product overview

TAG GmbH is Austria's leading gas transmission system operator, running the country's longest high-pressure pipeline network (~380 km / 1,140 km total across three parallel lines, operating at up to 70 bar). The core offering is the gas transmission pipeline system (TAG I, TAG II, TAG Loop 2), supported by five compressor stations with ~420 MW installed power. TAG's commercial products include primary market capacity allocation and secondary market trading via the PRISMA platform, the Reshuffling Service for capacity product exchanges, the Commercial Dispatching Platform (CoDiP) for nominations, and a Tariff Calculator. Supporting services include geodata/plan information, contractor procurement, and a gas alarm plan. TAG is actively transitioning toward hydrogen: the H2 Readiness project will convert one pipeline (380 km) for pure hydrogen transport (168 GWh/day), integrated into the European Hydrogen Backbone via the SoutH2 Corridor and SunsHyne Corridor initiatives. The network already transports biomethane without modifications and is being prepared for CO2 transport. TAG also operates waste heat recovery systems at compressor stations.

Products and services

• Gas Transmission Pipeline System Austria's longest high-pressure natural gas transmission pipeline system (~380 km route, 1,140 km total across three parallel lines TAG I, TAG II, and TAG Loop 2), operating at up to 70 bar pressure with five compressor stations (~420 MW installed power). Transports natural gas bidirectionally between Baumgarten (Slovak border) and Arnoldstein (Italian border) for system users including shippers and balance group representatives.
• Primary Market Capacity Allocation Transparent, non-discriminatory allocation of transmission capacity to system users via the PRISMA European Capacity Platform, with FZK (firm) and DZK (interruptible) capacity contracts at entry/exit points (Baumgarten, Arnoldstein). Regulated tariffs per E-Control Gas System Charges Ordinance.
• Secondary Market Services Capacity trade on the secondary market via PRISMA, including assignment (transfer of ownership) and transfer of use (utilization rights only). Allows system users to pass on contracted transportation capacity to third parties.
• Reshuffling Service Capacity exchange service allowing system users with long-term contracts (≥1 year) at TAG interconnection points to exchange existing capacity for new FZK products with different durations at another TAG interconnection point. Launched in 2024.
• Commercial Dispatching Platform (CoDiP) Web-based platform for balance group representatives to submit nominations and re-nominations 24/7 as an alternative or backup to AS4/Edig@s data transfer, supporting capacity management at entry and exit points.
• Tariff Calculator Non-binding online calculator for capacity-based transport fees based on the Gas System Charges Ordinance and E-Control methodology. Available on TAG website transportation services section.
• Geodata / Plan Information Service Free pipeline location information provided under the Environmental Information Act (UIG), including guidelines for safe working near gas pipelines. Available to planners, municipalities, and contractors.
• Procurement Services Supplier and contractor selection support, governed by TAG's General Conditions of Purchase, Code of Ethics, and contractor safety and information security requirements.
• Biomethane Transport TAG's existing pipeline system can already transport biomethane without requiring infrastructure adjustments, enabling renewable gas transport through TAG's high-pressure network.
• Waste Heat Recovery Waste heat from gas turbine compressor stations is recovered via waste heat recovery systems to generate electricity. One such system is already operational at the Weitendorf compressor station.
• Gas Alarm Plan Password-protected emergency communication system for reporting and coordinating responses to gas incidents. Accessible via dedicated phone line (24h Notruf: 0800 808 128) and web portal.
• H2 Readiness of the TAG Pipeline System Conversion of one of three existing gas pipelines (380 km) for pure hydrogen transport with capacity of 168 GWh/day (~1.5 million tonnes/year), part of the European Hydrogen Backbone and SoutH2 Corridor. PCI status granted by the EU Commission. Bidirectional design enables reverse flow hydrogen transport.

Regional players

• DESFA S.A. Greek gas TSO operating the high-pressure national transmission system plus the Revithoussa LNG terminal. Comparable in scale and role (regulated ITO-style TSO with hydrogen ambitions), but serves a different regional market (Southeast Europe) rather than directly competing with TAG's Central European cross-border flows.

Broad incumbents

• Snam S.p.A. Italy's largest gas TSO and 84.47% owner of TAG. Operates a ~3,300 km national high-pressure transmission network, including the Italian section of the SoutH2 and SunsHyne hydrogen corridors; structurally comparable as a regulated European gas TSO with parallel hydrogen transition strategy, but at much larger scale and broader geographic scope.
• GRTgaz: France's main gas TSO, operating the country's high-pressure transmission grid and developing hydrogen infrastructure (e.g., HY-FEN, mosaHYc projects). Comparable as a regulated, EU-backed gas TSO with active hydrogen backbone participation, though operating a national rather than cross-border corridor network.
• Enagás S.A. Spanish gas TSO and LNG terminal operator with an active role in the European Hydrogen Backbone (e.g., H2Med corridor). Comparable as a regulated ITO-certified TSO pursuing hydrogen retrofit of existing infrastructure, although primarily Iberian-focused rather than Central European.
• Open Grid Europe GmbH: One of Germany's largest gas TSOs operating ~12,000 km of high-pressure pipeline. Comparable as a regulated, ITO-certified European gas TSO with bidirectional flow, large compressor fleet, and an active hydrogen conversion programme, but at substantially larger scale than TAG.
• National Grid Gas Transmission: UK gas TSO operating ~7,600 km of high-pressure pipeline under Ofgem regulation with active hydrogen conversion projects (e.g., FutureGrid, HyNTS). Comparable as a regulated gas TSO with parallel hydrogen transition strategy and similar EU-aligned decarbonisation pathway, though structurally separated from EU market participants.
• Fluxys Belgium: Belgian gas TSO operating a cross-border transmission network connecting the UK, Norway, the Netherlands and Germany. Comparable as a regulated European gas TSO with hydrogen development plans, but with a broader geographic footprint and broader service portfolio (including LNG terminals).

Direct peers

• Gas Connect Austria GmbH: Austrian gas transmission system operator (TSO) that jointly owns TAG (15.53% stake) and operates the adjacent SOL system branching from TAG at Weitendorf toward Slovenia. Directly comparable as an Austrian ITO-certified TSO with cross-border gas and emerging hydrogen infrastructure, sharing regulatory framework and many of the same shippers.
• bayernets GmbH: German gas TSO and co-initiator of the SoutH2 Corridor alongside TAG, Snam and Gas Connect Austria. Operates a high-pressure transmission network in Bavaria that is the downstream leg of TAG's hydrogen corridor and shares regulatory certification, EU PCI participation, and a similar enterprise/government shipper mix.
• eustream, a.s. Slovak gas transmission system operator interconnecting with TAG at Baumgarten. A direct counterparty on the Slovak-Austrian border and a partner in the H2 Backbone WAG + Penta-West project, making it one of the most directly comparable pipeline operators on TAG's network.
