# Commission Regulation (EU) 2015/703 of 30 April 2015 establishing a network code on interoperability and data exchange rules (Text with EEA relevance), Article 6: Rules for flow control

Extent: E+W+S+N.I.

1. In respect of flow control, the adjacent TSOs shall:
(a) ensure that rules are established in order to facilitate a controllable, accurate, predictable and efficient gas flow across the interconnection point;
(b) ensure that rules are established for steering the gas flow across the interconnection point and for minimising the deviations from the flow pursuant to the matching process;
(c) designate the transmission system operator who is responsible for steering the gas flow across the interconnection point. If the adjacent TSOs fail to agree on this designation, the transmission system operator that operates the flow control equipment shall, in cooperation with the other transmission system operator(s), be responsible for steering the gas flow across the interconnection point.
2. In order to steer the gas flow, the adjacent TSOs shall decide on the quantity and direction of the gas flow for each interconnection point and for each hour of the gas day.
The transmission system operator designated pursuant to point (c) of paragraph 1 shall be responsible for steering the gas flow across the interconnection point provided that contractual obligations regarding pressure are complied with by all adjacent TSOs:
(a) at a level of accuracy sufficient to minimise the steering difference; and
(b) at a level of stability in line with the efficient use of the gas transmission networks.
3. The quantity and direction of the gas flow decided by the adjacent TSOs shall reflect:
(a) the result of the matching process;
(b) the operational balancing account correction;
(c) any efficient flow control arrangements between the adjacent TSOs for purposes such as ramp-up, ramp-down, minimum flow, split of the flow at the virtual interconnection point if any, and/or switch of flow direction or operational cost efficiency;
(d) any arrangement managing cross-border trade restrictions due to gas quality differences pursuant to Article 15 and/or odourisation practices pursuant to Article 19.
4. A transmission system operator may decide to alter the quantity of gas or the gas flow direction or both, if this is needed, in order to:
(a) comply with provisions laid down in ... safety legislation applicable to the interconnection point;
(b) comply with requirements laid down in Emergency Plans and Preventive Action Plans developed in accordance with Regulation (EU) No 994/2010 of the European Parliament and of the Councilas it has effect in EU law immediately before IP completion day;
(c) react in case the operator's system is affected by an exceptional event.
