The Government subsidy is welcome news for the Mayor of Wellington who
"Wellington Mayor Andy Foster said the $498,785 allocated would help
the council reach its goal of becoming a carbon-neutral capital by
Around 35 per cent of Wellington citys emissions come from road
transport, so this is an opportunity to support Wellingtonians who
want to transition to an EV [electric vehicle], but dont have access
to off- street parking or garaging, Foster said."
WOW! A whole THIRTY chargers. Great but what are they going to use in them
Rich. They'll need a couple of power stations to power all the other chargers
unless the plan is to restrict EV cars to Wellington :)
There are already quite a few chargers in Auckland - see
There are maps for locations of public chargers elsewhere in New
Zealand as well. In theory over time we will need more public charging
and fewer petrol pumps - some locations around New Zealand already
provide both; but most charging is likely to be done while a vehicle
is parked at home; I know of one person who has solar panels on the
house roof and electricity generated is stored in a battery, which is
used first for charging an EV.
Nobody in government is addressing the real issue. How is the electricity going
to be generated and stored? In your case you simply don't understand the
There is an interesting thread on this subject on geekzone - an
NZ-based technology website. In that thread there is a post with
cites that identifies that generating and transmission capacity to
supply the load required for just off-peak (overnight) EV recharging
is inadequate and the supply at any other time of the day is
non-existent (because Huntly is keeping the whole system afloat).
The fact is that if EV's are successfully marketed and sold, we need
to plan now for the increased clean-green generating capacity in order
for it to come online in the next 10 to 20 years. The current
Government seems to be unaware of this or they think we can wait to
see how market trends with EV's shape up.
A government some years ago took steps to remove government from both
electricity generation or distribution; we now have a market place
with a number of competing companies for each stage of delivery,
working in a free market to maximise profits though efficiencies and
taking advantage of competitive advantages between themselves. EVs are
often charged overnight. From above, there is currently an advantage
to our system in using off peak power, but that may not last.
For the owner of Manapouri, high demand is desirable, and closing the
smelter may release too much supply to sustain prices in the South
Isaland at least. The link across Cook Strait is possibly running
close to capacity; there may be advantages in spending the capital to
allow higher delivery north, but transmission losses suggest we should
be developing generation in the North Island anyway. In the short term
the answer is that for the North Island, prices are likely to
increase, which may make it more desirable for individuals and groups
to develop more solar generation. In the meantime, raising prices may
assist generate some of the capital needed for that development.
Given that we have such an effective market, the question does need to
be asked as to why some believe the governmen should be doing the work
for those market participants - if demand increases, then after prices
have increased sufficiently there will be an incentive for companies
to develop further generation as needed.
Are those wanting the government to "do something" prepared to pay for
that work? Or should they be charging the current electricity industry
body that is already doing projections of generation and demand and
sharing the results? Should the government set up a generation company
to compete in the industry itself? Or do those calling for the
government to get involved just have shares in current companies and
want a subsidy?
