I've actually met the Synota guys in person, gotten to talk with them a bit about the model.
The energy bill you pay is for electricity you've already consumed from weeks ago. You pay after the fact.
The idea is that paying as you use energy benefits energy providers, since they're receiving capital for others' consumption of their energy instantly.
These companies often have multiple subsidiaries they have to pay as well. The way we currently do things -- separate consumption from payment -- can place downstream pressures on energy companies who have subsidiaries on other regions. After energy companies get paid, they also have to go out and pay any subsidiaries, which even further delays when they get paid.
Synota is battle testing this idea right now with Bitcoin miners.
The high-level vision is synchronizing consumption with energy to make everyone's processes more efficient (and subsequently cheaper) over time.
I'm definitely not smart enough to validate the success of the idea, but Jeff Booth's egodeath capital is a big investor, among others.
