Participants in the National Electricity Market (NEM), Short Term Trading Market (STTM), Victorian Wholesale Gas Market, and Gas Supply Hub may be obliged under the Market Rules to provide credit support to AEMO.

This is the required format for Bank Guarantees in the STTM to cover Trading Participant security requirements. In accordance with Rule 478, each Trading Participant must provide security unless they are exempt.
