Article 9 Rules for the allocation of gas quantities

United Kingdom

Original text. Later amendments are not shown.

1.

In respect of the allocation of gas quantities, the F1adjacent TSOs shall establish rules ensuring consistency between the allocated quantities at both sides of the interconnection point.

2.

Unless otherwise agreed in the interconnection agreement, the transmission system operators shall use an operational balancing account. The transmission system operator in control of the measurement equipment shall recalculate the operational balancing account with validated quantities and communicate it to the F2adjacent TSOs.

3.

Where an operational balancing account applies:

(a)

the steering difference shall be allocated to an operational balancing account of the adjacent TSOs and the allocations to be provided F3by each adjacent TSO to their respective network users shall be equal to the confirmed quantities;

(b)

the adjacent TSOs shall maintain an operational balancing account balance that is as close to zero as possible;

(c)

the operational balancing account limits shall take into account specific characteristics of each interconnection point and/or the interconnected transmission networks, in particular:

  1. (i)

    physical characteristics of the interconnection point;

  2. (ii)

    linepack capability of each transmission network;

  3. (iii)

    the total technical capacities at the interconnection point;

  4. (iv)

    gas flow dynamics at the interconnected transmission networks.

Where the defined limits of the operational balancing account are reached, the adjacent TSOs may agree to extend those limits in order to provide allocations to network users that are equal to their confirmed quantities or otherwise allocate quantities to network users proportionally based on the measured quantity.

4.

The adjacent TSOs may agree to maintain or implement an allocation rule other than the operational balancing account, provided that this rule is published and network users are invited to comment on the proposed allocation rule within at least two months after publication of the allocation rule.
