This page outlines the requirements for registering as a Market Ancillary Service Provider (MASP) in the National Electricity Market (NEM).
A MASP delivers market ancillary services in accordance with AEMO’s market ancillary services specifications, by offering a customer’s load, or an aggregation of loads into FCAS markets.
