Manage Supply Point Registration

Customer Change Team Leader


Based on the findings of the UIG Task Force, as at December 2018 just 12 sites were contributing 0.85% of national LDZ throughput to annualised UIG and up to 0.3% of national LDZ throughput to daily UIG volatility. 

This Modification proposes that where the requirement for a Class 2, 3 or 4 meter point to become Class 1 (number of calculations and number of months) has been met, and the Shipper has not taken steps to convert the site to Class 1 within a 28 Supply Point System Business Day grace period, that the CDSP would take steps to convert the meter point to Class 1.

The Modification also proposes a new Performance Assurance report of sites where the CDSP has taken action, over the previous 12 months
