The 400 kV line to Auckland needs to be built soon.

In the local news rag there was an article for resource consent to increase the temperature of the Grid wires from 70°C to 120°C.
The reason for that is the extra sagging of the cables within allowable clearances. Imagine the powerlosses!! [Linked Image]

Other option is to triple or quadruple the current carrying conductors , which is common in Europe, OK it adds extra weight, perhaps the cost of strengthening towers and insulators may not outweigh the benefits.

The power here in West Auckland has gone up from 8.26 Cts kWh to 14.87 cts kWh in about 10 years, thats nearly double!! Now you pay extra for cable faults to your property and or point of entry, used to be included. Linecharges up from 20cts to 63cts / day.
Also the electricity commision levy of 0.17 cts kWh an other rip off tax.

Just something to ponder about.
Time for a nice coffee now

Cheers
