The Gas Governance (Critical Contingency Management) Regulations 2008 (the Regulations) were amended in 2013 following a recommendation to the Minister of Energy and Resources from Gas Industry Co. One of the amendments was to change the arrangements relating to Regional Critical Contingencies.
In the design of the original regulations it was considered that it would be obvious to industry participants whether a critical contingency was regional or not. As a result, the CCM Regulations did not specify who would determine that status or when. Subsequent feedback showed that Transmission System Owners (TSOs) wanted the status to be clarified as soon as possible during a critical contingency and that view was shared by a number of shippers. As a result, the 2013 amendments included the following requirements:
- the industry body (Gas Industry Co) must prepare and publish guidelines to assist the Critical Contingency Operator (CCO) to determine whether a critical contingency is a regional critical contingency;
- as soon as possible after determining a critical contingency, the CCO must determine whether it is a regional critical contingency and publish a notice of that determination; and
- during a critical contingency, the CCO must also consider whether any event has occurred that would cause it to revise the CCO's determination and, if so, publish a notice to that effect.
