Methodology for capacity determination

Below we provide information on the rules for determining the available transmission capacity in entry and exit zones of the transmission system.

The IES uses definitions in accordance with:
General principles:
Determination of technical capacity is performed on the basis of a mathematical model and mapping of the transmission network with the use of hydraulic calculation tools - SIMONE. Calculations are performed using manufacturer defined algorithms.
In the analyses, the loads at individual points take into account:
  • Transmission Contracts and Capacity Allocation / Allocation of Transmission Ability(PP/PZ) made,
  • Inter-operator Transmission Contracts (hereinafter ITCs) and the executed Capacity Allocation (PP),
  • the approved capacity allocation forecast and the concluded Connection Agreements insofar as the deadline for concluding the agreement under which gas delivery is to take place, as stipulated therein, has not passed.
In the hydraulic analyses, for the assumed network load, the Transmission System Operator (hereinafter TSO) analyses the system operation taking into account: integrity and operational requirements of the transmission network. In this way, taking into account the capacity at entry points, the available operational parameters of the compressor stations and the transmission system, the TSO determines the capacity that can be offered on a firm basis at individual exit points under the minimum pressure condition defined for a given exit point.
  1. Technical capacity means the maximum firm capacity that the TSO can offer to network users, taking into account the integrity and operational requirements of the transmission network.
    1. The technical capacity at individual physical exit points or at individual physical entry points belonging to a given relevant point may not be equal to the technical capacity of a given point.
    2. A change in the contracted quantities at one of the relevant points may affect the technical capacity of the other relevant points.
    3. In accordance with the Decree of the Minister of Energy, in the event of a change in the existing conditions or technical parameters of operation of equipment of an installation or network for an applicant classified in Group A and B, Subgroup II, it is necessary to determine the entry point to the system at which fuel for transmission will be transmitted. Technical capacity (or available transmission ability) can be verified once the entry point to the system is determined.
  2. Contracted capacity means the capacity that the TSO has allocated to the network user under the transmission contract and the PP/PZ and PZ. As defined (715/2009 Article 2, point 19) the allocated (i.e. contracted) capacity does not include signed connection agreements.
  3. Available capacity means the portion of technical capacity that has not been allocated and is still available within the system at any given time. The available capacity at individual physical exit points or at individual physical entry points belonging to a given relevant point is limited by the parameters of the technological and measurement system of the station. The local limitations of the line elements (limited diameters of connector gas pipelines) must also be taken into account. The available capacity at individual physical exit points or at individual physical entry points belonging to a given relevant point may not be equal to the available capacity of the relevant point.
