09/05/2018 - Exercise Paparua

The CCO conducted its annual industry exercise - "Exercise Paparua" on the 09/05/2018.
The exercise simulated a major landslip on the First Gas Ltd Maui pipeline in north Taranaki.  This resulted in the pipeline being isolated for 7 -14 days while repairs were carried out.  In order to conserve linepack and pressure in the transmission system, the CCO issued curtailment instructions affecting consumers in Bands 1 to 6.
