Practice note on prevalent DUML non-compliances

We have published a practice note that examines three of the most common non-compliance issues found in distributed unmetered load (DUML) databases.

Inaccuracies in DUML data has led to distorted settlements and increased costs for participants and ultimately, consumers.

The three most common types of DUML related non-compliance are:

• timely audit submissions
• failure to ensure database is accurate and
• recording database changes as a monthly snapshot instead of daily database updates.

Part 16A of the Electricity Industry Participation Code 2010 requires retailers with DUML databases to ensure they are audited. Regular audits support accuracy, transparency, and fairness in market operations.

A DUML database logs information on unmetered assets such as streetlights, billboards, traffic lights, and other electrical loads connected to an installation control point (ICP). The information in the database is used to reconcile the unmetered load.

Reconciliation compares the amount of electricity used by consumers with the amount supplied by generators. This process also calculates and invoices any electricity generated that hasn't been accounted for.
