Yes I total agree, NZ is a likely candidate for complete electricity (90% renewable) based economy (including transport) with high wind generation penetration. A flexible dynamic electrical load changing to the variable generation rates. The government is talking up electrical cars which would go hand in hand with such a grid, so hopefully Toyota will try out there new plug in hybrids on us!

Thats the spirit - a city like Wellington is a good size to run a V2G trial (and there is no problem with lack of wind in that part of the world either).
