Requesting a Procedure Change
Only the party responsible for a WEM Procedure can initiate the Procedure Chage Process for that procedure. Rule Participants may suggest changes to a WEM Procedure. All suggestions for amendment or replacement of an ERA WEM Procedure should be sent to market.compliance@erawa.com.au.
Requesting offer construction guidance
Market Participants that have received a notice from the ERA under clauses 2.16C.1(c)(ii) or 2.16C.2(d) of the WEM Rules may, in accordance with clause 2.16D.6 of the WEM Rules, request guidance from the ERA in relation to the Offer Construction Guideline.
For the ERA to consider providing guidance, a request must:
- be in writing, using the form linked below.
- identify the matters in the Offer Construction Guideline on which the Market Participant is seeking guidance.
- specify the Market Participant's reasons for seeking guidance.
- where relevant, provide supporting materials that illustrate or evidence the matters raised in the request.
A Request offer construction guidance form can be completed and submitted to market.compliance@erawa.com.au.
The ERA is only required to consider requests for guidance on the Offer Construction Guideline that pertain to WEM Rule 2.16D.5. However, the ERA may consider queries that are not bound by WEM Rule 2.16D.5.
