WEMS MPI USER GUIDE


1. INTRODUCTION

The purpose of this document is to describe the functions and capabilities of the WEMS Market

Participant Interface (MPI) and act as a guide to Market Participant users. The Market Participant

Interface (MPI) is the medium between the Market Participant (MP) and AEMO to exchange and submit

registration information, trading submissions and facilitate the extraction of reports.

This document is intended for MPI users.

2. SYSTEM REQUIREMENTS

The MPI is accessed via a web browser and AEMO recommends either Internet Explorer (IE) 9 or later

or the latest Google Chrome browser. IE 8 is supported but requires a Silverlight plugin to display the

BMO (Balancing Merit Order).

4. ACCESSING THE SYSTEM

Upon visiting the site https://wems.aemo.com.au/mpi, the MPI will require the user to authenticate with

their WEMS RSA SecurID token before the user is able to access the MPI. The RSA SecurID token can

be identified by the RSA SecurID dark blue and red logo with white writing as per Figure 1 below.

Figure 1 RSA SecurID Token Example

New users must apply for WEMS access by contacting their Market Participant Administrator (MPA) as

well as completing the WEMS Token Request Form. This form, along with the RSA Quick Reference

Guide is available from the MPI login page or from Market Operations (WA)

([email protected]).

Figure 2 Login Screen

New users must also be assigned the appropriate roles by their MPA to ensure they have the correct

access privileges.

RSA SecurID tokens are managed and issued by AEMO; however individual roles and user accounts

are managed by each MPA.

At the top of the form, the user should fill in a date for the Proposed Effective Date. This is the

date from which the Participant Information will be made effective in WEMS if it is approved by

AEMO. The user can pick a date from the calendar, or enter a date manually in the

dd/mm/yyyy format.

The Previous Effective Data shows the data that has been previously approved by AEMO and

is effective immediately preceding the new requested Effective Date for the current Change

Request.

The user can input new information into the New Effective Data column. All of the fields must be

filled out. If there are only a few sections to be changed, the user can click Copy Previous

Data to New Data Fields, which is at the top right side of the screen. This will copy all of the

previous data to the new form. The user can then edit the sections that are most relevant to

their change request.

When the Change Request form has been filled out by the user, click Submit, at the bottom of

the form. If the user decides not to submit the change request, click Back. After clicking the

Submit button, a popup screen will appear asking whether to submit this information for review,

click OK, and the user will be directed to the Pending Approval Window, where the Change
