For reference, the price for fixed-cost plans is around 10c/kWh.
As someone who’s been constantly running an electric heater in the garage while painting my car, I was quite lucky with the timing.
It’s not literally free, though. Transfer prices are fixed, and there are taxes and some other minor costs associated with it, so where I live, it still adds up to around 6c/kWh even when the price drops to zero. The cheap prices are due to an excess of wind power, but once the wind dies down, prices usually spike hard.
Nordic energy market is capped between -0,5€ - 2,00€/kWh (upper limit might go up if needed). Average market price for last 30days was 0,05€/kWh, which is fairly normal. Price currently is per hour, but market will change to 15min next year.
In Finland, we pay distribution separately, it is commonly 0,02€-0,05€/kWh, depending on the grid company.
On top of that there is electricity tax which is 0,03€/kWh.
Total is something around 0,12-0,15snt/kWh.
