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. - eviltoast

That massive spike of 50c/kWh at the left looks tiny compared to today even though that’s already insanely expensive

    Solar is quite poor in Northern winters. Wind + solar + heat would be a better bet, but the battery required to heat your house for more than a day with low winds would be prohibitively expensive unless you added geothermal to the mix like a geothermal heatpump which is also very expensive. Betweem the gear, battery, geothermal, all installed your probably in the 80k$ range or more. A wood stove would be the best bet

      Finland has about 5.2GW of wind capacity vs 4.3 nuclear. If it’s a windy day the spot price will usually be low.

        Good point, for aome reason i was thinking more off-grid than load balancing economics. The battery would probably help lower power by filling when power is cheap and supplying when the rates spike throughout the day
