It happened again, power was out in a large part of Auckland and up North towards Whangarei and Cape Reinga.

A 220 kV line going North was tripped in Onehunga while a large shipping container was within the safe M.A.D. of one of the main 220 kV lines.
A flashover occured to the container stacker.
The driver was ok but shaken.

The other main 220 kV circuit going North was out for maintanance, the trip of the other line caused a domino effect and power went off for about 1 hour.

It is being addressed that the system in Auckland needs a back up double circuit line going north which will take an other 5 years to be in place.

My question is why have a shipping container stacking yard within the easement of overhead 220 kV lines ?

Just a new topic to get some conversation going.
