Modifications

Enable additional daily metered Consumers to participate in gas DSR by introducing the role of an ‘aggregator’ to group Consumers’ DSR into a portfolio and offer it to National Gas Transmission (NGT).

To introduce further enhancements to Gas DSR arrangements for daily metered consumers following experience of recent reforms and based on consumer feedback.

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.

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)

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.
