And my prediction is we won't see a collapse in the wholesale price like what we saw in Australia.
But it does come down to making sure that we electrify just as fast as we're putting solar on the rooftops.
I mean, battery technology or battery paybacks are quite complicated at the moment.
We do not have an energy system that fairly recognises and rewards battery ownership, even though it will go a long way to reducing infrastructure costs in New Zealand that we all have to pay for on our power bills.
About half of our power bill is poles and wire costs.
So it gives you sort of an understanding there of the role that batteries will play in the future, because if you have a battery in a home, you remove that home from peak periods.
Just like highways, we don't build poles and wires.
We only build poles and wires for peak demand, right?
And if you can smooth out that load or reduce that peak demand, then it creates a better outcome for all New Zealanders as a whole.
But there are lots of different retail plans that will change the way that we will look at batteries.
And so if you can get three hours of power at nighttime, you know, that might be enough.
Or if you can get a low off-peak rate, you might not need a battery.
When you're, you know, looking at financing a battery on a mortgage, it probably comes in at somewhere around 28 cents a kilowatt hour to put a, you know, to cycle a battery.
So it is cheaper than peak rates, probably not cheaper than off-peak rates.
Yeah, so we've got all those metrics as well.
You're paying about $1,000 a kilowatt hour for a battery.
And so what we're seeing is about 50%, this is very anecdotal data now, but about 50% of solar installations that are going into New Zealand at the moment are going in with batteries.
And the rest are being built pretty much battery ready, which means we won't buy the battery yet, but we'll buy it somewhere down the path.
The best way that I can describe batteries at the moment is they're kind of like life jackets, right?
you don't really value them until you're in the water.
