NTS gas connections

On these pages, you will find out more about connecting to, diverting, and shipping using the gas National Transmission System (NTS). We manage the entire connections process. The NTS supplies gas to end consumers, including large end users, such as large industrial consumers and power stations, who receive gas directly from the NTS.

If you have any questions about NTS gas connections (for large industrial consumers) please contact us by email and we will be happy to help.

[email protected]

We offer three types of connection to the NTS: entry, exit, and storage. Our Gas Contract Management Team manages the entire connections process for, and relationship with, new and existing customers requiring connections and diversions to the NTS. We also provide support to gas shippers who wish to use the NTS, and those who would like to reserve capacity through the Planning and Advanced Reservation of Capacity Agreement (PARCA) and Capacity Allocation Mechanism for IPs (CAM) processes.
