At 6:30pm on 24 May 2016 the Critical Contingency Operator (CCO) declared a Critical Contingency. The underlying causes of the Critical Contingency were an unplanned trip of PPS at 4:20pm combined with the large gas demand on the day and depleting linepack. At 6:05pm, once the Critical Contingency threshold of 3 hours to 37.5 barg at the Kapuni Gas Treatment Plant was breached, the conditions for determining a Critical Contingency had been met. The CCO was required to determine and declare a Critical Contingency.
The Incident Report and Performance Report can be found on the CCO website here.
Critical Contingency Price
Under regulations 67 to 72, Gas Industry Co is required to engage an industry expert to determine a Critical Contingency price that will be applied to contingency imbalances sustained by interconnected parties and shippers during a Critical Contingency event. Tim Denne of Covec was engaged as the independent expert for this work. His final Critical Contingency price report is available below.
Pursuant to regulation 65 of the Gas Governance (Critical Contingency Management) Regulations 2008, the CCO issued a draft Performance Report which can be found below along with the submission received.
