LTiP

Demand assessment

By creating and maintaining the necessary transport infrastructure for gaseous energy carriers (natural gas, biomethane & hydrogen), the LTiP provides the basis for the efficient transformation of the energy system. A complete decarbonisation of the Austrian energy system cannot be implemented without a functioning gas infrastructure. It is therefore essential that this planning is based on profound data.

The demand survey for the current LTiP was carried out from December 2023 to March 2024. During that time the data for the demand model and the demand at entry and exit points were collected. Capacity expansion requests submitted by 1 March 2024 were included in the current planning.

In particular for the update of the H2 roadmap, market participants had the opportunity to inform their system operator or AGGM of their future site-specific methane and hydrogen demand via a non-binding questionnaire.

Planning

The demand model and the supply model for methane and hydrogen are created on the basis of the data provided. Hydraulic simulations were used to assess whether all end customers and the required capacities can be supplied at the entry and exit points in the distribution area. The necessary projects to maintain and expand the gas infrastructure - consisting of a methane and hydrogen network - for a climate-neutral energy system were then developed together with the network operators.

Consultation

The four-week consultation on the current LTiP took place from 28 October until 29 November 2024. During this period, market participants had the opportunity to submit comments on the current LTiP. These comments were taken into account in the LTiP.
