Urgent Modification 0791 - Contingency Gas Procurement Arrangements when a Supplier acts under a Deed of Undertaking

Summary

This Change Proposal has been raised to deliver the requirements associated with the Modification 0791 proposed process.

UNC Modification 0791 - Contingency Gas Procurement Arrangements when a Supplier acts under a Deed of Undertaking has been raised with Urgent status.

The Modification seeks to introduce new arrangements to enable National Grid NTS to procure gas where, following the termination of a Shipper User providing shipping services to one or more Gas Suppliers, no new Shipper User (a ‘Registered User’) is appointed and one or more of the Suppliers acts in accordance with its deed of undertaking until such time a new Registered User is in place.

The Modification proposes to create a new role for National Grid NTS, separate to its role as residual balancer, under which it would be obliged to procure gas to meet the forecast demand of Terminated Supply Meter Points that are temporarily without a Registered User (i.e. a Shipper). The target quantity of gas to be procured for each Day by National Grid NTS as the Contingency Procurer of Supplier Demand (CPoSD) in the period for which the arrangements apply would be the aggregate forecast demand of the Terminated Supply Meter Points, net of any trades enacted against the terminated shipper’s imbalance account provided for under Modification 0788 ‘Minimising the Market Impacts of Supplier Undertaking Operation’.
