In accordance with Table S22.214.171.124, 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.
