0857 - Revision to the Determination of Non-Transmission Services Gas Year Target Revenue

This Modification would revise the method of the determination of National Gas Transmission’s Allowed Non-Transmission Services Revenue for a Gas Year under the NTS Transportation Charging Methodology (TPD Section Y Part A-I). The purpose of this change is to mitigate, not remove, revenue volatility (where there is year to year revenue swings) to achieve a greater degree of year-on-year stability of target revenues in General Non-Transmission Services revenues, and therefore General Non-Transmission Services Charges.
