Lose the straits cable and everyone in the North Island is f***ed - or when the quake* takes out Haywards.
The Rio Tinto comment seems particularly WTF? - being south of the main power generation would mean anything down there would have f***-all affect on distribution issues in the North Island.
These are my thoughts and opinions - sometimes I'm wrong, but not often ;-)

"The smelter's power demand from the national grid is about 570 MW. Most of the energy for the smelter is supplied from the Manapouri hydroelectric power station, via two double circuit 220 kV transmission lines. The facility is the largest electricity consumer in New Zealand, and uses approximately one third of the total electricity consumed in the South Island and 13% of the total electricity nationwide, equivalent to about 680,000 households."  Wikipedia

yes and no.

electricity is affected by gravity.

but the effect is negligible.

so the effect of gravity drawing electricity south towards the smelter is offset by the centrifugal force generated by the earth's rotation which would tend to send it to the North Island?  8)

Don't try and be a smart-ass, guys - you can only do the latter part  :laugh:

Three things wrong with the windup - electricity moves in a circuit, or loop, so any perceived advantage in one direction is cancelled by the reversal in the other - and if anything, the earth's magnetic field would have more effect in a single direction.
The second is that it is just convention that has North to the top as there are other alternatives - http://www.bellerbyandco.com/index.php/globes.html so you can set your own perspecive, or for more conventional maps - https://www.flourish.org/upsidedownmap/
And, third, electricity needs a physical circuit to pass through and if it is broken - like losing the Cook Strait Cable or the Haywards transformer - it doesn't work or, come to that, the South Island end that converted the power from AC to DC for the cable.
