A Critical Contingency was declared at 19:36 on 13 July 2010 and was terminated at 22:34 on 13 July 2010. Under the Gas Governance (Critical Contingency Management) Regulations 2008, a number of reports have been published in respect of this event:
- Critical Contingency Incident Report, prepared by the Critical Contingency Operator under regulation 64. This report outlines the events that occurred that day and the actions taken by the Critical Contingency Operator and the Transmission System Owner.
- Critical Contingency Operator Performance Report, prepared under regulation 65. The purpose of this report is to assess the effectiveness of the Critical Contingency arrangements during the event and identify areas where those arrangements could be improved.
- 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 on a Critical Contingency day. Dr John Small of Covec has been engaged for this work.
