The area out here on Canada's west coast is tricky to power, and expensive; and we're as far from our nation's capitol as Tehran is from Berlin, with I imagine similar feelings of disconnect. It's a lot of overhead power-lines, nestled in among beautiful, thick, tall trees that really catch the wind during winter storms like the one now (go see on windy.com!). Those wires come down, maybe start a fire in the forest for the lulz, and teams of people in their trucks and cranes repair the breakage. It's planned and operated as well as our flatlander conservative opposition will permit (the cruelty to plebes is the point).
It should be noted that one of the biggest projects for power in this metro is the remediation of overhead power lines to underground cabling running alongside water and sewer service, much as Germany has done. It's trickier to fix, and thieves keep stealing it for the copper, but every time the ground was opened for any significant pipe work, our hydro-electricity supplier was there to use its access and string new cabling alongside whatever else was going in. Wiring that last-hectometer has been a challenge with the WWI-era homes, but even trenching up to a bungalow and running the cable up the side - so ghetto - gives us something unlikely to put people like Otter in the dark for so long.
But long-range power connection is still via strings of thick cabling up on the steel - or often wooden - poles, for long trunk-lines into the wilderness (so pretty!, and see how long that line runs), same as Germany will do. Then it's just the cost of accessing the transmission line to safely get there and fix it. With the vast distances they're traversing, breakage is both more likely and also more expensive to fix.
I'm in a new section of the metro, and the power infrastructure is solid aside from the blip and blinks caused by construction - for new buildings and for upgrades - in the area. It's been solid, so far, and 30 min drive probably from Otter's house could get her to mine. So the upgrades are happening, but it's slow, costly, and stymied at every stage.
