Introduction

• Greater number of audits during a Performance Annual Operating Period (PAOP), increasing confidence in Metering data entering Settlement;

• A greater degree of flexibility in Metering System Measurement Class selection;

• Improve the number of successful audits by removing the no access issue;

• Ability to target Site Inspection Visits where Settlement Error is more likely to have occurred;

• Lower resource requirements on Meter Operating Agents (MOA) and Licensed Distribution System Operator (LDSO); and

• Reduced planning required by Registrants in arranging site access.

Sample Selection

• Supplier Volume Allocation (SVA) Main Sample;

• SVA Specific Sample;

• SVA Targeted Audits;

• SVA Desktop Audit Sample;

• Central Volume Allocation (CVA) Main Sample;
