Here (in Estonia) the pricing changes every full hour. We get pricing for the next day (24h) a day before by 14 (2 pm). This is calculated from weather forecast, expected consumption and available generation resources. This is for residential use. For industrial applications you can buy electrical energy from the grid based on 15 minute pricing slots. Almost all the houses are equiped with online readable power meters.
I think this is the way things are moving in other jurisdictiins as well. In case of Germany and France one of the reasons why the systems have mot been upgraded lies in the privacy rules for the power consumption data according to one smart meter manufacturer.

Not just that, in addition the smart meters cost a bunch of money to install... people don't like paying anything very much.
Norway is going all-in on smart meters, installation has been rolled out this year to ~80% of the country, due to reach 100% next year. The total installation cost is estimated at around 2.5 billion USD for around 2.2 mill. houses, i.e $1000 per house. Which of course we as consumers will be paying for through higher electricity prices.
