I've read of concepts where you export your excess home solar power to the grid and sell it to a large scale battery farm. noting they are unlikely to pay more that 8c per kwH.
Or maybe they just charge you a 'holding fee' and you can store and then use your stored power to recharge your car anywhere in NZ. Or sell it to anyone else who wants it.
The battery farms could also support the grid during sags, maybe the battery company will pay you if they use your excess to prop up the grid ?

Amusing to see all the people predicting 3 million EVs or grid armageddon, completely missing the point of the incentives.
There are very few EVs in NZ. Something like 1.5% of the fleet. This doesn't make a lot of sense in a country that has lots of renewable electricity production (90%) to have to pay $$$ mainly to the middle east to import oil. And keeping a loss making refinery going.
So given the average price of a BEV is say $50k plus right now, they are still not going to represent the majority of imports, and even if they did, going to take a while for them to even hit 10% of the fleet.
So to quote a good book, Don't Panic.
But if it triggers a few more people switch from buying a new BMW or Audi and get a Tesla series 3 instead, then that is all good on emissions reductions.
Take a look at Norway. a country similar to NZ in many respects, which has more incentives. they are managing the grid with 50% of all new cars registered being EVs

I would be a lot happier with this if they were using NZ coal.
It was around the early 1990s I've still got VHS copies of the 1min and the 30sec Ads. I think only Bill Cotton (Akl Japanese car parts centre) and I were the only ones doing (Car wrecking) TV ads at the time

On the subject of lithium batteries, my neighbour lost 3 sheds, a car, all his tools and a big freezer full of food in a fire caused by a lithium battery in a cordless drill.

100,000 new cars sold each year in little old Nz.
50% of that = 50,000
Well that's a relief. At that rate it'll take ONE CENTURY before all our ICE cars change to EV's.
I reckon well have the charging capacity by then.
Stand down Gents, & Ladies, and don't panic - untill the next Govt announcement.
God knows what that'll bring.

Thats about the time the hot water heating gets turned off .! What about the Clown Greens and saying that there will be EV charging stations every 75 kms.Hope they,ve got multiple charging points.!

Didnt they(lithium batteries) get the blame for the aircraft fires?

As I said to Tony9, you are assuming that all EV owners would be charging their EVs every Night/day. I hardly think that all EVs would require a charge within every 24 hour period. There will be (most) those that don't use all the available Battery power every day, or indeed use their EV everyday or so.

Hopefully more votes for ACT so they can control the idealogical idiots in labour and the Gweens.
My bad, should have said ATK, but in fact pretty much any liquid hydrocarbon.

Similar in many respects, but not power generation. They have so much Hydro that they export electric power. Helps having other countries close.
The really interesting bit is that EVs are subsidised to the point of being cheaper to buy than ICEs, fuel (electricity) for the EVs is free or cheap, but still 50% of cards sold are ICE.

Norway installed capacity V NZ.
" At the end of 2020, the total installed capacity of the Norwegian power supply system was 37 732 MW (37.732 GW) "
NZ is 9.7 GW but with water and gas resource restraints it's more like 6-7GW on an average day.
Or 1/5th of Norway. not quite apples with apples.

NZ has relatively low capacity as it enough to meet our needs. so why build more when consumption in NZ has not been growing much. About 10GW vs 30GW of capacity according to Wikipedia so about 3x more in Norway.
They export a fair bit, but the staggering difference to me is that they use about 27MWh per person whereas NZ uses about 9MWh. So again they use about 3 x more power per person - before EVs started really taking off. Almost like a cold country needs more heating or something.
Given we have many years before EVs even get to 10% of the fleet, the point remains; we have a long time to build more generation and grid. Paid for by not importing as much oil.
EVs are so much more efficient, that even if we burnt some of that fossil fuel in gas turbines like the decommissioned South Downs plant in Auckland, it would be an easy solution if need be, but don't think we need it; as others have said we have capacity ready to go, we just have not had demand.

What "capacity ready to go"? Please enlighten us.

So then back in the 80s cars were way more expensive, especially if you wanted a fancy "Turbo" model.
Biggest short term change I think would be if Tiwai shut down freeing up 600+ MW of generation from Manapouri. With the newspaper paper mill at Kawerau shutting down, that will free up some geothermal.
That is all grid generation; at the same time PV installation are getting cheaper, so there will also be a stream of micro generation. It was impressive to see Gt Barrier running on solar and tiny micro wind turbines everywhere

From what I,ve read the Power not used if Tiwai Point closes down can only be used in parts of the South Island and to get to the North Island requires a massive and expensive upgrade of the transmission system.

Folk talking about lack of capacity, solar roof tiles - sorted!
