Register as a Customer in the NEM

This page outlines the requirements for registering as a Customer in the National Electricity Market (NEM).

A Customer is a registered participant that purchases electricity supplied through a transmission or distribution system to a connection point. Retailers and end users who buy electricity in the spot market must be registered as Market Customers.

A Market Customer can deliver market ancillary services in accordance with the National Electricity Rules and AEMO’s market ancillary services specifications, by classifying their market load or an aggregation of their market load as an ancillary service load (ASL).

Participants who are already registered as a Customer in the NEM, and who wish to change their scheduled bid and offer data, should visit the Changing Scheduled Bid, Valuation Data and Offer Valuation Data page.

This page also provides information for participants, who are already registered as a Market Customer, classifying market load as ancillary service load (ASL).

Note: Once your first application to classify non-scheduled ASL has been approved, to amend or classify new ASL, you will be required to manage your applications through the Portfolio Management System (PMS). Applications to classify scheduled load as ASL are not managed through PMS.
