UNC 0926S Maintenance criteria for Emergency Contact data held in Central Systems

Summary

This Change Proposal has been raised to deliver the Central System changes required as set out within UNC 0926S.

This modification outlines the criteria for how all emergency contact data (EMR data) must be recorded and maintained in Central Systems. It covers the following:

1) The Supply Point criteria where EMR data is mandatory and is permitted to be maintained in Central Systems.

2) The treatment of non-mandated EMR data* and the circumstances in which it may be held by Central Systems, including, but not limited to, the mechanism by which non-mandated EMR data shall be deleted from Central Systems after a contiguous 12-month period of not meeting the criteria.
(*EMR data is mandatory for Supply Points when the AQ is ≥732,000kWh OR The Supply Point is an Interruptible Supply Point).

3) No differentiation between the treatment of EMR data regardless of Supply Point type. Ie. Large Firm Supply Point & Interruptible Supply Point EMR data is to be maintained consistently. Ie. maximum number of contacts which can be submitted is 5.

4) Confirmation that EMR data can be submitted for any Larger Supply Point* with the understanding that the owning Shipper expects and warrants that the Supply Point will soon meet the criteria for mandatory EMR data in the near future. (*Larger Supply Points have an AQ >73,200kWhs).

5) Confirmation that the Shipper warrants, prior to submission to Central Systems, that they have permission from the end consumer to share EMR data with Central Systems as per the parameters outlined in UNC post 0926S implementation.

6) Mandatory EMR data that has not been updated for >36 months will trigger a notification to the Shipper requesting that they review the EMR details held in Central Systems. If the Shipper updates EMR post this notification, then the clock of >36 months will restart. If an update is not received, Central Systems will retain the emergency contact details against the Supply Point and the original effective date shall be maintained.

Assumptions:
• The existing rules around when a Carry Over Flag is applied are to continue.
• NTS Supply Points, CSEPs and IGT Supply Points are included in this change.

Implementation is expected to occur from UNC0926S implementation effective date. No transitional rules are anticipated.
