The number also depends on whether you consider “short term” vs. “long term”. Maybe it is 38% down at the moment, but they have spare parts to get some of it back up.
But they’ll run out of spare parts rather quickly if Ukraine keeps up the speed. And then it gets interesting.






Yep. It really depends on if you have to replace some basic hardware like pipes, tanks, and valves that you can do with sheet metal and a welding tool, or if they blew up the control center with the computers and the specialized hardware. Or maybe some of the specialized pumps and valves. Those are expensive, and so nobody has large quantities lying around.
When the Russians hit the Ukrainian power grid, the Ukrainians can get replacement parts from all over Europe and the rest of the world. But Russia has the problem that those parts are high up on the embargo lists, so they have to get either Chinese parts (which may need modifications on them or the controlling software), or smuggle the original items.
