Notices published by the Critical Contingency Operator (CCO) during a critical contingency event are available on the CCO’s website click here

Following the termination of a critical contingency, the CCO is required to publish the following reports:

• Incident Report (regulation 64), which outlines the cause and duration of the event, actions taken by the CCO and transmission system owner, the level of general compliance by retailers and consumers with directions issued during the event, and another other matters the CCO considers appropriate.  The Incident Report must be issued as soon as reasonably practicable, but no later than five business days after the critical contingency is terminated.

•  Performance Report (regulation 65), which assesses the effectiveness of the critical contingency arrangements during the event, and identifies areas where those arrangements could be improved. This report must be issued no later than 20 business days following the termination of the critical contingency, or as otherwise agreed between the CCO and Gas Industry Co as the industry body.

In the case of a non-regional critical contingency, regulations 67-81 provide for a process for setting contingency imbalances.
