Extending the PC4 Read Submission Window (Mod0884)

Summary

This Change Proposal has been raised to deliver the requirements outlined in Modification 0884.

Required changes because of Modification 0884:

Modification 0884 seeks to amend the Product Class 4 read submission window outlined in UNC TPD M 5.9.4 to allow Shippers more than 25 Supply Point System Business Days after the actual read date to submit a meter read for Settlement.

This change intends to amend the Class 4 read submission window for SMPs with a Market Sector Code (MSC) of ‘Domestic’ to 80 Supply Point System Business Days after the actual read date to submit a meter read to Central Systems.

It also intends to amend the Class 4 read submission window for SMPs with a MSC of ‘Industrial and Commercial’ to 45 Supply Point Systems Business Days after the actual read date to submit a meter read to Central Systems.

Downstream impacts highlighted in the ROM:

Increasing the Product Class 4 read submission window may have downstream impacts on a number of processes including:

1. the Must Read process;
2. the Rolling AQ process;
3. the Annual Formula Year AQ/SOQ process;
4. Meter Point Reconciliation;
5. UIG Reconciliation;

for SMPs which have reads submitted past the current 25 SPSBDs.It is worth noting that during modification development it was stated that later submission of reads is expected to be an exception rather than the norm.
