NMI approved energy metering plays a critical role in accurate electricity measurement, compliant billing and fair cost allocation across commercial, industrial and multi tenant environments. Approved meters are tested against Australian requirements to ensure energy consumption is measured reliably where electricity usage data is used for billing or financial settlement.
This page serves as your knowledge hub for NMI approved energy metering and compliance. From understanding pattern approval requirements and meter selection to installation, commissioning and ongoing data management, you will find practical guidance, technical information and expert updates. Explore how NMI approved meters and energy management software can support accurate billing, improve visibility and provide dependable data across complex electrical networks.
NMI approved meters are essential in apartment buildings, shopping centres, retirement villages, business parks and other multi-tenant properties where electricity use is measured for billing. They help ensure each tenant is charged according to accurately recorded consumption.
Reliable metering also supports clearer cost allocation between common areas, individual tenancies and shared services. This gives property owners, operators and embedded network managers greater confidence in billing data and helps reduce disputes.
Commercial and industrial sites often need to measure electricity use across buildings, departments, production areas or individual pieces of equipment. NMI approved meters provide dependable data where energy costs are being allocated between different users or business units.
Accurate metering can also support energy reporting, budget control and operational decision-making. By identifying where electricity is being consumed, organisations can better understand costs and improve accountability across the site.
Renewable energy generators rely on accurate metering to record the electricity produced by solar farms, wind farms, hydro systems and other eligible power stations. NMI approved meters provide dependable energy data that can support Large-scale Generation Certificate (LGC) calculations and compliance reporting.
Reliable metering helps reduce the risk of inaccurate claims, data gaps and audit issues. It also gives generators and project operators greater confidence that recorded generation data can be traced, verified and used to support certificate creation.

Four quadrant metering separates import, export and reactive energy at Australian sites. Learn how it works, why direction matters and which meters suit.
The SRES expands to 1 MW from October 2026. Here is what bigger commercial solar means for metering, self consumption and site data.
The NMI Approved Energy Metering Blog Library is designed to be your central hub for understanding the requirements that support accurate electricity measurement, compliant billing and fair cost allocation. Where electricity data is used for trade, tenant billing or financial settlement, the meter must meet relevant Australian legal metrology requirements. Our collection of blogs explores NMI pattern approval, meter accuracy, verification and practical applications to help you understand what compliant metering involves.
Here you’ll find practical guidance on selecting NMI approved meters, meeting NMI M 6-1 requirements and understanding verification procedures such as NITP 14.2. From embedded networks and multi-tenant properties through to commercial facilities and renewable energy projects, this library brings together clear and actionable content to support property owners, metering providers, engineers, retailers and energy professionals in maintaining accurate, reliable and compliant electricity measurement.
National Instrument Test Procedures (NITP) form part of the legal quality assurance systems, as mandated by the National Measurement Institute (NMI). NMI works to assure accuracy verification is done for all electricity meters used within Australia for Trade Measurement or Billing. National Instrument Test Procedures for electricity utility meters is known as NITP-14. Electricity metersRead more
SATEC introduces the first NMI approved fit for purpose retrofit electrical energy meter with the EM133-XM-HACS energy billing meter. The DIN rail NMI pattern approved electrical energy meter has Class Accuracy 0.5S, providing a full range of electrical measurements such as KW, KVAR PF, HZ, Volts, Amps, Harmonics, and other electrical and energy measurements. SplitRead more
SATEC’s release of the NMI approved EM133-XM eXpertmeter takes smart energy metering to a high-level design far exceeding any DIN energy meter products currently on the Australian Market.
Electricity energy meters for use in the Australian market must be Pattern Approved, this involves a process of assessing and testing the electricity energy meter to comply with metrology conditions per NMI M 6-1.
Many sceptics thought it was impossible to achieve NMI Approval for a Multifunction Electricity Meter designed in a compact DIN rail footprint. In fact many doomsday forecasters predicted electrical switchboard enclosures, distribution boards, riser/cupboard spaces for multifunction metering would have to be increased in size to accommodate larger electrical metering to be in compliance for Energy Meters per NMI M 6-1.
SATEC continue to set the standard in Energy Metering design with the release of the NMI Approved BFM136 Multi Circuit Meter, suitable for use on multiple electrical circuits.
One of the many technical and metrology requirements for obtaining pattern approval and verification from The National Measurement Institute (NMI) for any active-energy electricity meter to be used for trade is for the energy meter to pass the 12KV impulse test.
Any din rail electricity meter used for sub-metering is now required to comply with NMI testing standards for energy meters.
From January 2013, the exemption for energy meters used for trade (billing customers) was lifted, meaning energy meters used in residential, commercial and other businesses environments must now have NMI (National Measurement Institute) approval.
