This is literally how most electricity is charged. I’ve been in probably 30+ non European countries and it is frequently billed this way. Potable water is usually the same. Residential users rarely exceed the standard allowance so they never come across tiered pricing.

In fact most larger cities not only have tier pricing but also peak pricing inside tier levels.

Commercial and industrial is its own game, they have tiers and on/off peak charges along with load shedding requirements. Often it’s billed not just kWh but also peak amperage draw.

Edit: by load shedding I mean commercial/industrial end users often have to be able to accept incoming excess power from the grid that residential use isn’t consuming due to weather/events grid failures etc. Power grids are immensely complex and very interesting beasts.
