We pay the one hour spot price for power.
The power company called me the other day and offered a fixed-price fixed-term electricity contract for two years at about 8 cents for the power. My prompt answer was "No, thank you." and they didn't even try to convince me otherwise because they knew what a bad deal it was for an ordinary consumer such as our household whose power bills are around €50 per month with the current spot price based contract that we have.
Even if the price went up by 20%, which I doubt it will, the spot price contract would still be the overwhelmingly cheapest option. The Olkiluoto 3 NPP has been running without a hitch since last spring with some ability to vary its output and the newly installed wind power capacity is massive. Any cold and calm snap during the winter will probably be short enough not to warrant paying for the huge markup for every single hour that the power company would pocket for the vast majority of two-year period.
The latest 28-day average price of power (not including transmission, the peak power fee and the constants in the bill) was about 2 cents.
