Metrology Procedures and Unmetered LoadsNational Electricity Market (NEM) metrology procedure
The metrology procedure is made in accordance with clause 7.14 of the National Electricity Rules (the Rules), and is comprised of two parts:
- Metrology Procedure: Part A National Electricity Market.
- Metrology Procedure: Part B: Metering Data Validation, Substitution and Estimation Procedure for Metering Types 1–7.
The metrology procedure applies to AEMO, registered participants, metering providers, and metering data providers, in relation to connection points in the NEM that may be classified as a first-tier load, second-tier load, market load, or intending load, in accordance with clause 2.3.1 of the Rules.
The metrology procedure provides information on the application of metering installations to connection points, and sets out provisions for metering installations and metering data services.

In accordance with Table S220.127.116.11, Item 5(c) of the Rules, the metrology procedure must include arrangements for unmetered loads that have been classified as market loads. Consequently, the metrology procedure requires AEMO to publish:
- The NEM Load Table, which lists the load values for unmetered market load.
- A Guideline, to provide industry with assistance in determining the device load values for an unmetered market load device.
Unmetered loads that are not included in the NEM Load Table (that is, off-market unmetered loads) are the subject of arrangements determined through consultation between LNSPs, FRMPs (typically Local Retailers), interested parties and end-use customers.
