Connection Agreement

The Connection Agreement called (Aansluitovereenkomst = AO) is applicable to connected parties (industries) connected to the national grid. The Connection Code  Gas - TSO specify that this type of agreement is a condition for the creation of a physical link between us and the industrial connection.

GTS also uses 2 other kinds of agreement in addition to the Connection Agreement (AO) mentioned above, i.e.:

  • Connection Agreement called Systeemverbindingsovereenkomst (SVO): applicable to connections between the national gas transmission network and the gas transmission networks of local distribution companies (LDC).
  • Grid Connection Agreement (GCA): applicable to other connections (such as border stations and storage facilities).

What does the Connection Agreement (AO) regulate?

The Connection Agreement (AO) covers all agreements relating to the connection between the industrial connected party and the national gas transmission network operated by GTS. The Connection Agreement (AO) provides both the industrial connected party and us with clarity about eithers responsibilities and tasks. As the agreement relates to a long-term physical connection between high value infrastructures, it is important for both parties to make unambiguous agreements. This relates not only to the conditions under which the gas is delivered (pressure, quality, capacity), but also to how deal with adjustments to these conditions or to the installation.

The different elements of the Connection Agreement (AO)

The Connection Agreement (AO) is signed by both parties and consists of the following elements:

the Agreement
the Agreement, in which the contracting parties, the contractual relationship under the Network Code and the effective date etc are laid down.

General Terms and Conditions
the General Terms and Conditions, which supplement the Networkcode and which regulate how to deal with e.g. gas quality, pressure, capacity, measurement, termination, building and planting rights, liability, and force majeure

Appendix 1
the appendix ‘Technical Specifications’, in which the specific parameters of the connection are laid down, such as capacity, pressure, gas quality, and contact details in the event of disasters;Technical Specifications

Appendix 2
the appendix ‘Drawing of the transfer point and the physical situation’.

FAQ

  • It is important that both minimum and maximum capacity are known. The maximum capacity is given in normal cubic metres per hour at a temperature of 0°C and a pressure of 1013 mbar and with an energy content Hs of 35,17 MJ/m3. The maximum capacity is a determining factor for the design and dimensions of the connection point. We need the minimum capacity in conjunction with the off-take pattern in order to verify the measuring equipment provided by connected parties.
    The off-take pattern raises questions about anticipated use. For example, connected parties may consume more gas in the winter for space heating, so a summer/winter pattern is involved here. Sometimes there is also a continuous (low) basic off-take with regular peaks that are a multiple of the basic off-take.
    In brief, the off-take pattern indicates how connected parties’ installations are operated and provides insight into the possible fluctuations in gas consumption between minimum and maximum capacity.

  • In order to be able to make the best possible choice for a connection point it is important to know where a connected party wishes to locate its gas receiving station. For this purpose, we need the coordinates for the planned gas receiving station and, if possible, also a map/sketch/drawing/Google Earth photo indicating the location of the gas receiving station.

  • Article 17 of the General Conditions for Connection Agreements, version 2.0 accompanying the connection agreement  describe the conditions under which termination is possible.

    In addition, article 6.A.11 of the TSC deals with the supply of transmission capacity in the event of bankruptcy or business cessation.
