It's still worth it if you have a lot of load you can shift to the middle of the day (like a pool heater or battery), but for most 9-5 workers you just end up paying more at the times you're actually home.
Smart meters are free, most people already have one.
I thought most Australians had different pricing for peak/off-peak. I'm paying 39c/kWh for peak (3pm to 9pm) and 20c/kWh for off-peak (9pm to 3pm the next day).
Sure, a battery isn't available to everyone. But I is available for many.
One would have to do the math, cost of battery versus 24kw free daily. But clearly for lots of people the math will work.
A side effect of policies like this is effectively getting people to invest capital to time-shift elec usage. That's good policy. Reducing the peaks in consumption solves other problems.
I know, this doesn't really address the core issue, but is stuff like balcony solar legal in Australia?
Here in Germany, it is absolutely massive and an increasing number of people run their balcony solar with batteries that just feed into a regular Schuko Plug. It only allows to feed in 800W at a time, but there are workarounds for that as well
The utilities don't really want to sell you the cheap solar. They'd rather write op-eds about how too much solar is flooding the grid and beg for more money to invest in the grid elements they can make money from.
The government is having to force them to reflect the abundance of cheap, clean energy at these times in at least one of their tariff offerings.
They can bend the rules slightly by adding other daily charges or limitations and upping the price at other times to reduce uptake and move us all slightly further from the global optimum but maximize their profits.
After: 30c/kwh most of the day, 0c from 11-2
