Watching the prices fluctuate here, it's very annoying that we don't have a way to buy power when it's cheap, store it, and sell it back when it's expensive, as consumers.

The incentive to place storage into your house would be so much better if this were possible. It feels like people have been writing papers about this for years but no one has made it happen. I think people would be willing to self fund new meters themselves to participate.

Exactly that is happening here in Australia.

People buy solar and batteries and hook up with Amber[0] who charges a static monthly fee but provides access to wholesale prices. When you give/take from the grid is for you to manage.

So, now you have kind of a non-scaling side hustle when you really just wanted to have cheap energy without having to think about it.

I've heard various people say good/bad things about Amber. People who say it works automatically, some say it doesn't sell to the grid at times it should etc etc.

But I think it is an interesting world when households can be used to support the local grid. And maybe more interesting because now there are more hackable targets on the internet relating to the local grid....

In the UK there's a number of people doing that with smart meters.
