Price of electricity in Finland peaks at 2.35€/kWh today. Keeping my tiny granny cottage warm costs me over 50 euros for a single day. It's negative 25C (-13F) outside.
That massive spike of 50c/kWh at the left looks tiny compared to today even though that's already insanely expensive
Are you actually paying the daily spot price? Not a flat amount with the utility provider taking the hit? That's how I know it from any other country, unless you have a specific contract where the user made an informed decision to opt for market rates.
Mainly the reason is that many countries do not have hourly capable meters, so calculating the price for each hour is not possible. Flat rate is needed when you just have the cumulative read once a month.
In Finland the meters communicate automatically once a day, and send the 24h values to grid company. The next generation meters which are now installed can communicate once a hour.
Sounds more like an incentive to put up solar panels and battery storage. Even if it isn't enough to go off grid totally, you can at least store on cheap days.
