A-C

  • Change of Direction

    Change from one Day to the next from Injection (or Draw-Off) to Draw-Off (or Injection) activity.

  • Connection

    Set of Branch line(s) and Delivery Station(s) intended to carry the supply to the end consumer

D-H

  • Daily Capacity

    Maximum quantity of Energy that the Shipper may either make available to the Transport Manager at a Large Scale Transport Grid Entry Point or take from a grid Delivery Point, or which may be allocated to a grid Exit Point, every day, as defined in the Transport Contract.

  • Daily Peak Draw-Off Capacity

    The additional draw-off capacity available under certain conditions in the case of a Dynamic Offer. It is equal to 26% of the Nominal Daily Draw-Off Capacity and independent of the Stock Level.

  • Daily Standard Draw-Off Capacity

    The Quantity of Energy defined each day by multiplying the Nominal Daily Draw-Off Capacity and the Draw-Off Adjustment Factor for that Day.

  • Delivery Conditions

    Stipulations regarding delivery set out by the Eligible Customer in their Connection Contract. They are defined in terms of nominal, minimum and maximum values of the delivery pressure, as well as the minimum and maximum flow through the equipment at their Delivery Station.

  • Delivery Point

    Point where the Transport Manager makes the gas available to the Shipper for delivery to the Eligible Customer. It is located at the output flange of the corresponding Delivery Station(s).

  • Delivery Station

    Delivery facility whose primary functions are Pressure regulation and gas volume measurement.

  • Draw-off Adjustment Factor

    For a given Customer on a given Day, a percentage between 0 and 100, dependent upon the Storage Level achieved by that Customer the previous Day. It enables the Daily Standard Draw-Off Capacity for that Day and that Customer to be established.

  • Eligible Customer

    Customer authorised to enter into a natural gas supply contract with their chosen supplier.

  • Energy Quantity

    Quantity of gas transported over the grid, expressed in MWh. That Energy Quantity is obtained by multiplying the volume of gas by the gross calorific value (GCV) of natural gas.

  • Entry Point

    Point on the Large Scale Transport Grid where the Shipper makes the gas available to the Transport Manager under the terms of a Transport Contract.

  • Exit Point

    Point where the gas leaves the Large Scale Transport Grid and enters the Regional Service Grid or the grid of an Adjacent Operator.

  • GESIP

    Groupe d’Etude de Sécurité des Industries Pétrolières et Chimiques [study group for safety in the petroleum and chemical industries].

  • Hourly Capacity

    Maximum quantity of Energy that the Shipper may either make available to the Transport Manager at a Large Scale Transport Grid Entry Point or take from a grid Delivery Point, or which may be allocated to a grid Exit Point, every hour, as defined in the Transport Contract.

  • HSSEQDD

    Hygiène Santé Sécurité Environnement Qualité Développement Durable [Hygiene, Health, Safety, Environment, Quality, Sustainable development]

I-M

  • Injection Adjustment Factor

    For a given Customer on a given Day, a percentage between 0 and 100, dependent upon the Storage Level achieved by that Customer the previous Day. It enables the Daily Standard Injection Capacity for that Day and that Customer to be established.

  • Main Grid

    Grid which interconnects the Entry Points with adjacent operators (transport, storage and production operators). It primarily comprises pipes of large diameter.

  • Maximum Stock

    For any given Day, the product of the Storage Capacity and the Maximum Stock Level for that Day. This is the maximum Energy Quantity in Stock that a Customer may hold on a Given day.

  • Maximum Stock Level

    Coefficient, expressed as a percentage, in the range 0 to 100, enabling calculation of the Maximum Stock for a given Day and Customer.

  • Minimum Stock

    For any given Day, the product of the Storage Capacity and the Minimum Stock Level for that Day. This is the minimum Energy Quantity in Stock that a Customer may hold on a Given day.

  • Minimum Stock Level

    Coefficient, expressed as a percentage, in the range 0 to 100, enabling calculation of the Minimum Stock for a given Day and Customer.

  • Movement

    The type of service provided by TIGF to a given Customer. A Movement is described as Injection if the quantity of gas delivered by the Customer to TIGF is intended for injection. It is described as Draw-Off if TIGF returns a quantity of gas to the Customer. Over the course of any given Day, a Movement may only be either Injection or Draw-Off. If no Movement takes place during a given Day (no amount of gas is stored or returned), then the Movement on that Day is considered to be Injection if the previous day’s movement was Injection. It is considered to be Draw-Off if the previous day’s Movement was Draw-Off.

N-P

  • Nominal Daily Draw-Off Capacity

    Maximum quantity of Energy that a Customer may ask TIGF to return to them on a given Day (except under Special Circumstances).

  • Nominal Daily Injection Capacity

    Maximum quantity of Energy that a Customer make make available to TIGF on a given Day so that it can be stored (except under Special Circumstances).

  • Operational Procedures

    Part of the Contract describing the respective obligations of the Parties concerning the exchange of information in relation to the fulfilment of the Contract.

  • Public Distribution

    Term used to refer to communes where gas is distributed to private customers, small businesses or tertiary sector activities.

Q-Z

  • Quantity Drawn Off

    Quantity of Energy which TIGF has delivered on a given Day to a given Transport Storage Interface Point, in fulfilment of the Contract.

  • Quantity Injected

    Quantity of Energy which TIGF has taken on a given Day from a given Transport Storage Interface Point, in fulfilment of the Contract.

  • Regional Grid

    Grid whose purpose is to carry the supply from the Large Scale Transport Grid to Consumer Points which are not directly connected to it.

  • Shippers

    Legal person who has who has entered into a transport contract with the Transport Manager. The Eligible Customer may be their own Shipper or may engage a third party company specialising in gas shipping to act on their behalf.

  • Special Circumstance

    A situation of Force Majeure, Planned or Unplanned Maintenance etc. which limits the capabilities of TIGF and thus the entitlements of its Customers.

  • Standard Offer

    Storage service, excluding Additional TIGF Services, provided under the terms of the Storage Access Contract.

  • Stock

    On any given Day, a Customer’s Stock is equal to the Stock of the previous day increased by the Quantity Injected for that Day or reduced as appropriate by the Quantity Drawn Off for that Day. The Stock cannot be negative and must lie between the Minimum Stock and the Maximum Stock.

  • Stock Level

    Quotient defined each Day by the ratio between the Day’s Stock and the Storage Capacity.

  • Storage Access Contract

    Contract binding TIGF and the Customer for the provision of access to natural gas storage installations operated by TIGF.

  • Storage Capacity

    Maximum quantity of subscribed Energy that the Customer may, on their own behalf, ask TIGF to keep in storage. That quantity is used to calculate the amount of the standard offer.

  • Storage Transport Interface Point

    Point where the Customer makes the Gas available to TIGF, in fulfilment of the Storage Access Contract.

  • Storage Unit

    Set comprising:
    - a Unit Storage Capacity;
    - a Nominal Daily Unit Draw-Off Capacity;
