The construction of a pipe-line by a gas transporter is within section 14(1)(f) only if (when constructed) each of the conditions in subsections (2) to (5) is expected to be met in relation to the pipe-line.
The pipe-line must be wholly or partly in England.
Either—
The pipe-line must have a design operating pressure of more than 7 bar gauge.
The pipe-line must convey gas for supply (directly or indirectly) to at least 50,000 customers, or potential customers, of one or more gas suppliers.
In the case of a pipe-line that (when constructed) will be only partly in England, the construction of the pipe-line is within section 14(1)(f) only to the extent that the pipe-line will (when constructed) be in England.
"Gas supplier" has the same meaning as in Part 1 of the Gas Act 1986 (c. 44) (see section 7A(11) of that Act).
