Do normal households and small businesses keep track of prices ? Are they able to cap their bills in any way ?

In my country, where I live, the per unit prices are fixed and any increases are announced. I doubt whether people anywhere could keep up with 10-30x changes in prices.

Smart meters are extremely popular in places that have flexible pricing. And given that electricity is expensive in lots of places, there are lots of home owners and businesses spending lots of money on solutions that help them reduce their energy cost. Even simple things like off peak tariffs can drive stuff like this.

As far as I know many electric contacts for end users have fixed prices. (Potentially with some auto price correction every year or so based on averages, but this shouldn't matter for now.)

Given that this are wholesale prices it about how much the company selling electricity to end-users pays for it to (simplified).
