Summary

There is no process to ensure that the Supply Point Capacity (Often referred to as “SOQ”) and Supply Point Offtake Rate (often referred to as “SHQ”) allowed in a NExA (which is a contract between the site operator and the Transporter) and that allowed by the UNC (which is contract between the Relevant Shipper and the relevant Transporter) are aligned. This can result in discrepancies where the Shipper books more capacity on the System than the customer is allowed to use in accordance with the NExA.

 

Modification 0701 has been raised and seeks to improve visibility where a consumer has entered into a bi-lateral Network Exit Agreement (NExA) with the relevant Transporter and to link capacity increases with the NExA so that the allowed capacity does not exceed the capacity as agreed in the NExA.

 

This Change Proposal has been raised to deliver the system requirements set out within this Modification.

 

The Interim solution was implemented on 12/09/2022.  The enduring solution proposed implementation November 23.
