I live in Ukraine and run a software company here. I still don’t understand how the power grid is still functioning and how quickly it is repaired after an outage. I’ve been here since the war started, including some of the worst hit front line cities like Kharkiv and power outages after strikes were always resolved within a 48 hour period max, usually faster. How it’s possible to replace damaged substations within hours, I have no idea. Now I live in a relatively quiet area with a solar inverter battery (similar to the Tesla wall) and I have almost uninterrupted power sufficient to keep my business going. Just have to avoid using heavy appliances like the washing machine when on battery power.

Realy impressive, we have places (north sweden) after the last storm that took 7 days to restore power.

  That's probably because it's so remote. If it was a city in the south of Sweden it wouldn't take that long.

  Reminds me of about 7 days of prominent power outage (13.01.2024 - 19.01.2024) during Linux 6.8 merge window.

Power grid operators around the world are used to storms taking out their local grid all the time. Some storms are worse than others, but the world has gotten good are repairing damage fast. Ukraine is drawing on that experience for a lot. Substations are hard only because of quantity. Every power operator has experienced a substation having a catastrophic failure so they keep spares of the big parts on hand so they can restore power in hours when that happens. The only difference here is normally they are doing a few of these per year (and most of that is planned end of life replacements not sudden catastrophic failure) not a few per day. Manufactures of substations have had to scale up their production to meet Ukraine's needs and this is the real hard part. The rest is just normal overtime (that has been going on for several years now), and thus the normal overtime fatigue.

There's a song called 'Wichita Lineman by Glen Campbell. Has anyone ever done a Ukrainian cover for it? It's the only song I know that celebrates their work. I am a lineman for the county And I drive the main road Searching in the sun for another overload. I hear you singing in the wire. I can hear you thru the whine And the Wichita Lineman Is still on the line. https://www.youtube.com/watch?v=Q8P_xTBpAcY https://www.youtube.com/watch?v=Q8P_xTBpAcY Maybe 'Operator' by Jim Croce would get an honorable mention https://www.youtube.com/watch?v=Bb85NvjbBm8 https://www.youtube.com/watch?v=Bb85NvjbBm8 Also, I apologise for the way my country is acting (America). I fear we are soon to have a crisis of our own.
