Does this exist anywhere in the world?
It's really cool. Sometimes the price goes below zero - "plunge pricing" - if there is too much production and too little use. They give you the pricing info for today and tomorrow ahead of time, not sure how they predict future pricing - probably based on weather forecasts, since they only use solar and wind?
I have WiFi smart sockets on things like electric heaters to turn them on when electricity price is below my threshold level. It's a nice feeling being paid for using electricity. If you have an electric car you could also programmatically only charge it when electricity price is below a certain level. Octopus also have an EV leasing company, thinking of selling my current car and leasing one from them after covid19 is gone to a degree that I still need a car again.
Here are their dev docs:

They even have an open graphQL API and a storybook - how many utility companies you know who do this? Looks like Octopus hired the right people!

Though yes, it would have been better if I could have adjusted.
Still, the conclusion is like you said. There's basically no real-world scenario where it makes sense for a residential customer to go it alone, because they can make at most a couple hundred bucks a year. So makes sense for their device companies or someone else to figure it out with utility and pay thousands of homeowners to agree to participate. Ohmconnect has a cool service in California.
The real big thing is aggregating the aggregations. Distributed Energy Management Systems (DERMS) / Virtual Power Plant Management Systems are an active research topic.
