Yes, just ideal for the guy who does the 2 am run to Greymouth carrying the Christchurch Press and gets back to Christchurch in time for a late breakfast.

>The answer usually is.--Ohh they will build more power stations! ARE THEY ? - Where are the RC applications? Where are the plans? where is even some intent to build stations. ?
Notice how much of the list is either consented or in the consent process.
In short the power industry isn't building much stuff because power demand growth is pretty minimal. Any extra power used by the likes of EV's is offset by efficiency improvements elsewhere, or demise in industry. Plus you have the departure of the smelter hanging over the industry that could potentially depress wholesale power prices for a decade.
My view is that some serious reform (or nationalization) is needed in the energy sector to force the move to more renewable generation.

As above, the entire national fleet of cars converted to EV would be (ignoring transmission losses and complexities, back of envelope) satisified by the output of one Manapouri sized station.
There are already consented wind farms alone which could potentially meet that, they just havn't been built because the demand isn't there YET.
Fossil fueled stations have their place because of their ability to rapidly spin up and down as the load demands, but as we get more energy storage solutions, battery or the posited pumped hydro, this will reduce in need.
While getting away from fossil fuel power stations is absolutely a good thing, it's not a bad thing to use them to power your EV in the meanwhile, firstly it is much easier to make a single power station cleaner and more efficient than it is to make all ICE vehicles cleaner and more efficient, and secondly when said fossil fueled plants are replaced with renewable ones and storage solutions then instantly the fleet gets greener.
"Oh but but coal is powering it really" is not a good reason to avoid an electric vehicle, it's about the worst reason.

In 1969 $7285.00. in 1976 $20600. 1979 $32,000. last import 1987 $102,000.

Of course of course lolllol are you European ?

What caused the big increase between 1979 and 1987 ?

You're way off! I have most of the prices here in a Identicar book and so I can quote you the costs of most vehicle from the late 1960s - 1991/2. The basic Toyota Corolla DX 1.3L would have cost you $16,795 in Oct 1985. a 1989 Toyota Camry was $45,000.

Are you not assuming, that all EVs need to be charged every Day/night? Surely an EV (fully charged and not used for 1-7 days) doesn't require charging every 24 hours!

Yep, I paid $10k for a new Sigma 1.6L in 1979. My old man paid $3.5k for a new Hunter in 1972

Everything increased. A house could be bought for less than $10k in Auckland back in 1969. By the time the end of the 1980s came along same house would have set you back $100K+. Now probably $1.2m+

anyone about to buy a fuel efficient car that generates less than 146g of CO2 per KM should wait until Jan 2022, as you'll get a rebate.
I reckon there will be a pause on purchase of efficient hybrids or small cars this year, then a huge demand next year.
Meanwhile, there will be some stockpiling of popular cars and utes before 2022, the trick is to be able to sell them before Jan 2022.

NZ’s total power generation, with all coal stations going full steam, is currently around 9.7 GW
In NZ light vehicles travel an estimated 42 billion per kilometres per year.
A 40kwH Nissan Leaf (and we are talking a piddly Nissan Leaf) gives 270km, or 5 hours city driving at an average of 50-60kph
This equals 8kwH per hour of driving (of a Nissan Leaf).
If you use 8kwH to drive 50kms, then how much extra electricity does NZ need to generate for 25% of light vehicles to go EV
I.e how much power is needed for EV's to travel 10 billion kilometres per year @ 8KwH per 50 kilometres.
At 8kwH per 50km, how much more generation will we need for EV's to travel 42 billion kilometres per year ?

" Most people charging at home use just a standard 10A plug in power connection overnight. ". cough ! 2.4kw for 8 hours = 19kwH, less 10% efficiency losses = 17kwH. A piddly Nissan leaf is 40kwH and uses roughly 8kwH to drive 50km, so long as you never drive more than 90-100kms in a day you'll get by, but just.
300,000 houses at 2.4kw for a solid 8 hours is a fair chunk of power for any local network.

Most 'normal' houses which heat water and cook with electricity use around 20kwH per day. 19kwH to put a daily 17kwH (50%) back into your (Piddly) Nissan Leaf effectively doubles your power load and your power bill.
And just because it is at night off-peak may no longer apply because now there are 300,000 other EV's charging, then off-peak no longer becomes off-peak, increased rates could apply.
A flat 60kwH Tesla uses the same daily power as 3 houses.

6.72 GW with the figure you have given and that's if everyone bought a Nissan Leaf lol.

The Tesla Model S 60kwH weighing 2,045kg is rated at 18.1 kWh/100 km
Tesla Model S 75kwH @ 2,188kg is rated at 18.5 kWh/100 km
Dunno if that is rated with 1 or 2 or 3 people, air-con on, etc.

So it could be right to say we need an extra 8GW for 42 Billion Kms per year.
Interesting in the USA they have found people with EV's tend to drive more because it is cheaper and they like it more.
Given NZ's hydros can't keep up with our current demand, hence why we have burnt more coal then in the last 3 months than in 2 years,.
Then where is this extra 8GW (almost double our current production) of electricity coming from ?

If you take 1975, $12,000 is well over $90k in today's money. A lot of money when you think the average wage was about $95 a week
You can buy a few Jag for less these days, and the new car will of course be better that the 75 model in all respects

I have a receipt dated 1986 for a brand new ‘86 Mazda 626 GLX, that car cost $26,000.

Your maths is better than mine, does that equate to 6.72GW or 6.72 GWH ? Cause maybe I'm confusing GW of generation base with GWH of consumption ?

That figure is unobtainable. Huntley used to be able to maintain a load factor of 75% out of a total of 1000MW, assuming one out of 4 turbines was out for maintenance at any point in time. I guess it will be about 70% now.
Geothermal would be about 70-80% due to plant and bore maintenance.
Hydro overall would average about 35% due to water availability.
Wind, about 20% due to availability of wind and maintenance.
Reality is with water and gas constraints at the moments NZ is on a knife edge. Frequently we see 100-150Mw of diesel and/or Avgas being burnt in gas turbines.

Reform is needed, no doubt. The generator companies have zero interest in more generation as it would constrain wholesale prices. Ironic when the Govt owns over 50% of the major generators. Mind you the Govt is creaming the system with dividends and tax on profits.
About the planned generation shown above, bear in mind that wind only has a load factor of 20% at best. So a big wind farm of 800MW is only going to actually produce at a rate of 200MW at best and needs to be backed by fast response hydro.

Our fantastic Politicians, who know everything of course, will just wave a magic wand and everything will be as they want it to be - you'll see.
That's what they want you to believe. They're so up themselves they think they know better than everyone else in the country - they DON'T.
Theres a lot more work to be done to electrify this country in a 'green' way. And I doubt it's going to work as they wish it will. But they'll have plenty of excuses !

Avgas ? Or JetA1 ?
