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
You could get fixed price plans for around 5c/kwh. However take into account that yesterday was an anomaly. The average price for the last 28 days is 12.65c/kWh. During the summer time it was around 1 to 3c/kWh.
