I once asked a big cheese at Transpower if Tiwai closed would they extend the Southern terminal of the HVDC from Benmore to Manapouri? He said no as there would be sufficient AC transmission capacity from Manapouri to Benmore.
I dont know much of the technical stuff but wouldn't an electron generated at the bottom of the South Island be puffed by the time it got to the area of greatest NZ demand(Auckland Isthmus/Waikato)?
Boop boop de do
