Article 2 Definitions

For the purposes of this Regulation, the definitions in Article 2 of Regulation (EC) No 715/2009, Article 3 of Commission Regulation (EU) No 984/2013^f1, F1and Article 3 of Commission Regulation (EU) No 312/2014^f2F2... shall apply. In addition, the following definitions shall apply:

1. (a)

   ‘exceptional event’ means any unplanned event that is not reasonably controllable or preventable and that may cause, for a limited period, capacity reductions, affecting thereby the quantity or quality of gas at a given interconnection point, with possible consequences on interactions between transmission system operators as well as between transmission system operator and network users;

2. (b)

   ‘initiating transmission system operator’ means the transmission system operator initiating the matching process by sending the necessary data to the matching transmission system operator;

3. (c)

   ‘lesser rule’ means that, in case of different processed quantities at either side of an interconnection point, the confirmed quantity will be equal to the lower of the two processed quantities.

4. (d)

   ‘matching process’ is the process of comparing and aligning processed quantities of gas for network users at both sides of a specific interconnection point, which results in confirmed quantities for the network users;

5. (e)

   ‘matching transmission system operator’ means the transmission system operator performing the matching process and sending the result of the matching process to the initiating transmission system operator;

6. (f)

   ‘measured quantity’ means the quantity of gas that, according to the measurement equipment from the transmission system operator, has physically flowed across an interconnection point per time period;

7. (g)

   ‘operational balancing account’ means an account between F3adjacent TSOs, to be used to manage steering differences at an interconnection point in order to simplify gas accounting for network users involved at the interconnection point;

8. (h)

   ‘processed quantity’ means the quantity of gas determined by the initiating transmission system operator and by the matching transmission system operator, which takes into account the network user's nomination or re-nomination and contractual provisions as defined under the relevant transport contract and which is used as the basis for the matching process;

9. (i)

   ‘steering difference’ means the difference between the quantity of gas that the transmission system operators had scheduled to flow and the measured quantity for an interconnection point.
