Modifications

UNC TPD (Transportation Principal Document) Section Y part B only permits Distribution Network Operators (DNOs) to charge positive unit rates to Shippers, this modification permits negative rates.

This Modification seeks to align obligated Code Communication methods with future communication network changes, attributable to national PSTN decommissioning, to prevent undue disruption to the GB gas industry.

To provide a remedy for Erroneous Transfers that have failed to be progressed (exceptions) within a reasonable period to be proactively managed by the Central Data Services Provider (CDSP)

This Modification proposes amendments to the current Unidentified Gas Reconciliation Period arrangements to reconcile UIG to the same months that the energy originated from (instead of smear over previous 12 months).

The purpose of this Modification is to acknowledge the extent of Transporters’ obligations to accept gas tendered for delivery to (or make gas available for offtake from) the System in the provisions that set out the charges payable where a User utilises the System without holding system capacity.
