• Transit
    A key element of the liberalisation of the gas market is the possibility of transporting gas through the pipelines of other companies. For this, the required conditions must be contractually regulated  in a supplier framework agreement that effectively governs the rights and obligations of all involved within the scope of the network access. After initial obstacles and bottlenecks, the "transit"  generally works smoothly, which contributes to a lively competition.
  • Transit costs
    The transit costs are the costs charged by the network operators for the transport of "third-party" natural gas through their networks. The fees are monitored and approved by the Federal Network Agency. According to a study by the Federal Association of Energy Buyers (VEA), the transit costs for natural gas in Germany amount to €0.0021 to €0.0118/kWh, i.e. an average of €0.0052/kWh (November 2009).
  • Transmission network operator
    The service providers that operate the infrastructure of supra-regional power networks and are in charge of their maintenance are referred to as transmission network operators. For example, they also make sure that network fluctuations are kept low. In Germany, there are four transmission network operators:
    • Tennet TSO
    • 50 Herz Transmission
    • Amprion and
    • TransnetBW.

    As the transmission network operators hold a natural monopoly, there are statutory regulations to ensure non-discriminating network access.
  • TTF
    The Title Transfer Facility (TTF) is a virtual trading point in the Netherlands.
