Accessing WEMS

Market Participant Interface access

The Market Participant Interface (MPI) is a web based application which allows Market Participants to trade in the WEM as well as access market related data.

The Market Participant Administrator (MPA), as appointed by each market participant, is able to manage the level of access of individual users through the user management in the MPI.

If you need to nominate a new MPA, or wish to have an additional MPA, please fill out the Market Participant Administrator (MPA) Nomination Form and return to Market Operations (WA).

If you require access to the MPI, please complete the WEMS Application for WEMS Access Form and return to Market Operations (WA).
