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

How's the heat pump gang doing in that kind of temperature?
It's what I exclusively heat my house with
They are mostly ground source over there, which shouldn't be affected by cold snaps.
They should be using supplement heat sources at that temperature.
Since it's a cold area, they're likely using a geothermal heat pump, which isn't affected by air temperature. It uses the ground for heat exchange rather than the air.
Some of the modern air-source heat pumps can operate down to those temperatures. https://carbonswitch.com/best-cold-climate-heat-pump/
You're right though, geothermal would be more likely currently and if that's the case then the heat pump gang is doing just fine.
Definitely. I live in the San Francisco Bay Area where it doesn't get too hot nor too cold, but I do still need heating during winter, and occasionally air conditioning during summer (maybe for 3 weeks or so, sporadically turning on during the day).
I bought the cheapest heat pump I could find that would work with my existing Ecobee thermostat (a Gree Flexx), and even that one says it'll work down to -22F with a 1.25 COP
I've got solar panels, which made a heat pump a better choice than a new gas furnace.
