Original timeline overview

Requirements definition progress

• Excellent engagement – ‘requirements register’ being worked through

• Some aspects outside UNC – e.g. some iGT matters, industry data management

• Some matters stalled pending understanding of scope of SMIP – subsequently re-started

• Some key UNC industry requirements considered in detail – industry definition drawing to conclusion – year end target

Current timeline overview

Scoping Additional

Moving to the next Phase

• Preparing for economic, efficient, next phase with longevity

• Pre-requisites:– Defined requirements, expected outcomes and benefits– Priorities and dependencies

• Analysis of industry requirements

• Consider solution options

• Develop a delivery plan– reflecting the volume and nature of change – ensuring continuity of services

• Gain customer commitment

• Implemented UNC modification(s) [maybe in parallel with above]

Requirements Defined

& Signed Off

The development of a delivery plan may require iterations to fully work through the functional and non-functional requirements.

Mod 380 is part of a ‘family’: demand attribution, allocation and reconciliation

A ‘family’ of processes and objectives:

• Reduced reliance on allocation – Allow for more DM on back of AMR and Smart

• Increased accuracy of NDM allocation – AQ representative of more recent usage (mod 380)– Introduce more EUCs – potentially support for modest change

• Reduced risk of AQ ‘gaming’– Remove AQ amendments– Oblige shippers to submit all readings?

• NDM reconciliation attributable to individual sites– Meter point reconciliation

Keeping the family together!
