Yeah,

and margins are quite often not made at the retail end.

They're made often at the trading part, where they're buying and selling of energy.

The retail part is hard miles.

You've got to maintain a customer relationship, get the accurate readings, get the bill out, handle the customer service.

And to make a few percentage points on that, for most businesses, that'd be a business not worth having.

It's a lot of effort for a relatively small percentage return.

I wonder if you could tell me a little bit about what opportunities you think there are in some of these new applications of artificial intelligence in improving retail.
