Any individual may identify the need for an Urgent Rule Amendment using the
Market Rule Amendment Submission Form
Urgent Amendments may be identified as a result of the occurrence of a
specific event in the market that requires an immediate amendment to the Market Rules.
An urgent amendment to the Market Rules can be required for one or more of
the following reasons:
- To avoid, reduce the risk of or mitigate the effects of conditions that affect the ability of the integrated power system to function normally.
- To avoid, reduce the risk of or mitigate the effects of the abuse of market power.
- To implement standards or criteria of a standards authority.
- To avoid, reduce the risk of or mitigate the effects of an unintended adverse effect of a market rule.
Each submission should clearly identify the area of the rules under question, state the proposal, provide reasons for the proposed change, explicitly indicate that the amendment is urgent and identify which criteria was applied to make this determination.
