Key terms for the market survey


This glossary provides a brief overview of key terms used in the market survey and the planned further procedure. In the event of any contradictions, the explanation in the Terms and Conditions of Participation and the description of the project shall take precedence.

Freely allocable capacity (fac)

With freely allocable capacity, the entry and exit capacities within a market area can be combined freely. The capacities are fixed. This applies to the availability of the virtual trading point too.

For marketing issues on PRISMA the german abbreviation fzK will be used.

Dynamically allocable capacity (dac)

With dynamically allocable capacity, the entry or exit capacities have an assignment restriction. This assignment restriction can vary and is marked with a number (dac-dac4). It means that only specific network points can be reached, although this capacity is fixed. In contrast, the virtual trading point is available on an interruptible basis, i.e. only when this is possible.

For marketing issues on PRISMA the german abbreviation dzK will be used.

Market area boundary

Transition point between one market area and a neighboring market area (market area boundaries with market areas outside the European Union are included) as viewed independently of the existing infrastructure and without focusing on individual transmission system operators or network points.

Technical study

Modeling for each market area boundary with which the necessary technical development or conversion measures for one or more capacity levels are determined. Once modeling is complete. capacity levels for specific network points will be defined.

Economic test

A test for evaluating the feasibility of projects for offering new capacity. 

New capacity

This refers to a possible increase in technical capacity or future additional capacity which is provided through investments or the long-term optimization of the network and after a positive market test (at existing boundary transition and/or market-area transition points, by constructing one or more new boundary transition and/or market-area transition points, as physical counterflow capacity which was not previously offered). 

Offering level

Capacity offerings based on the network expansion measures that have been derived from the results of the market survey and the technical studies. The levels differ depending on the market area boundary (border crossing point) and can be viewed here.

Preliminary agreement

Conclusion of a preliminary agreement on the capacities required for economic network expansion will give transport customers and the more capacity TSOs the security they require that the desired capacities will be offered or requested in the annual auction.

Parallel auction

The more capacity TSO will offer its existing capacities and new technical capacities as part of the 2017 annual auction in a multistage auction procedure in accordance with Art. 17 of the Network Code Gas Capacity Allocation Mechanisms. The auctions for existing capacities and new technical capacities will be held in parallel. New technical capacities are indicated separately by means of a suitable index or marketed by means of auxiliary points. Existing capacities and new technical capacities are offered with the Supplementary Terms and Conditions of Business at existing border crossing points. If the more capacity TSO offers multiple offering levels at a network point, it will create additional and identical network points in the form of auxiliary points on the primary capacity platform PRISMA and market a further offering level for each auxiliary point. Following the annual auction, the more capacity TSO will decide as part of an economic analysis which offering level is to apply as the basis for expansion. If a transport customer has made a successful bid on multiple offering levels, all bookings of new technical capacities that are not regarded further will be canceled by the more capacity TSO.
