So when you're talking about the changes of how we look at energy across our communities, can you just talk us through what does that look like right now? Because we've come a long way from just looking at coal and gas.

So I'm going to jump out from the large-scale utility assets Nigel was just talking about to this small-scale revolution almost.

Australians lead the world almost in our investment in rooftop solar.

On a per capita basis, I think we are, if not the one of the leading nations for how many households have invested in their own rooftop solar which has done amazing things for our transformation towards renewables but comes with its own challenges because you know sun shines at the same time approximately every day that's when we get all that generation for people's houses from their own rooftops but then in the evening you've kind of got this massive sudden drop because sun goes down all at their fellow stops and they'll need the same amount of electricity and in fact if not more because it tends to coincide with that time of day when people are getting home and need to use more So adding the battery storage into the household level is, sorry, I've used this word twice in a very short space of time, but a game changer because what it means is at a household level, not only can they create their own electricity during the day and use whatever they can during the day, they can now store it for themselves and use it during that evening peak.

And so we've seen already, like I think there's now half a million have been rolled about through the cheaper home batteries program, is that what we were famously calling the duck curve in the wholesale market pricing because of that kind of very big change in demand from the middle of the day when it was really low when everyone was using their solar and so the price completely fell off and then it really spiked up at the end of the day when all the households suddenly needed to get grid scale power.

It's starting to really flatten out.

In fact, I heard somebody call it a platypus the other day.

How is that resonating with Canberra and with state governments? Are things moving in terms of understanding where the technology is meeting the requirement?

Yeah.

Think about it.

I am.

And I'll also confess.

So I recently got solar and batteries for the first time.

And I spent ages trying to work out what to get, what plan would work for me.

Like, and I've been in the energy sector for even longer than 15 years.

But it is a question of...

Why has it become so difficult?

So, one of the things that we have done to date is we try and keep the cost of the network down and we try and do that by pricing in such a way that people who can respond to price signals and move their electricity consumption around do that.

And that is really effective and it's a good tool to use.

But not everyone can do that and not everyone wants to engage with that.

So, rather than those network price signals being passed through and experienced by customers, what we're saying is, well, there's a retailer standing in the middle there.

Network costs are an input to the overall price of electricity and the overall structure of the tariff that you pay.

And let's get the retailer to look after the complexity.

How expensive is loyalty for some consumers, Anna?
