IAMMETER Upgrade for Australian Users: NEM12 Data Export & Import

— Billing Reconciliation and Electricity Cost Optimization for Australian Solar and Energy Users

Starting from October 2025, IAMMETER will introduce NEM12 data format export and import, helping Australian solar users, energy consultants, and business customers meet local compliance requirements and optimize their electricity bills by comparing electricity retailers.

What is the NEM12 Format (Australian Energy Data Standard)?

In Australia, energy data management must comply with AEMO (Australian Energy Market Operator) regulations. NEM12 is the most commonly used data exchange file format for storing and transferring interval data from smart meters.

Electricity retailers, distributors, and MDPs (Metering Data Providers) typically use this format for:

Electricity billing
Energy data reconciliation
Compliance reporting

For solar users and customers looking to optimize their electricity bills, the NEM12 format is also a critical tool for communication and comparison with electricity retailers.
