Article 8(1) of the Gas (NI) Order 1996 authorises the holder of licences issued under –
sub-paragraph (a) of that paragraph to participate in the conveyance of gas from one place to another; and
under sub-paragraph (c) of that paragraph to store gas.
These licences are subject to standard conditions. There are also conditions attaching to particular licences. Article 60(1) of the Energy (Northern Ireland) Order 2003 provides for the Department of Enterprise, Trade and Investment, after consultation with the Northern Ireland Authority for Energy Regulation, to modify the conditions of particular licences or the standard conditions where it considers it necessary or expedient to do so for the purposes of implementing or facilitating the operation of arrangements designed to secure that prices charged in connection with the conveyance of gas through certain designated pipelines are in accordance with a common tariff which does not distinguish (whether directly or indirectly) between different parts of Northern Ireland or the extent of use of any such pipeline.
This Order designates the pipelines to which this power of modification applies.
Each pipeline is described in the Schedule and the designation has effect from the date of coming into operation of the Order until the date specified opposite the pipeline in the Schedule. However, the Order also specifies certain events on the happening of which, the Order (or so much thereof as designates any particular pipeline) shall cease to have effect. These events are set out in Article 3.
