NDM Check to Check Reconciliation – Enduring Solution

Summary

The coverage of this change proposal is around the reconciliation process and invoicing of this to Shipper Users.

For Class 3 and 4 sites with Automated Meter Reading (AMR) equipment, Check to Check (C2C) reconciliation is performed when a site visit or RGMA actual read is received. This reconciliation must be based on the prevailing consumption which can be:
• The deemed allocated position – The position calculated for the Commodity invoice with no subsequent reads, or
• Actual consumption – Where readings exist, or
• A combination of both - If readings exist but do not account for the full. C2C period

Currently, the deemed allocated volume/energy, is always used as the prevailing position with existing readings not considered.

The objective of this Change Proposal is to ensure that, during a C2C reconciliation the tru prevailing volume position is used.
