Figuring out the long term damage is not as simple as figuring out which targets got hit. If a power plant got hit, the first thing they are going to do is shut the thing down and figure out the damage. It may turn out that that only one turbine was damaged and hole was made the wall. They clean up the mess and put the undamaged turbines back on-line and at least some capacity is back on line in short order. Or it could turn out that the critical controls for the entire plant were put out action and the plant cannot run until they are replaced and parts to enable the plant have a six month lead time. In extreme cases, the entire plant may be flattened and the entire plant will have to be rebuilt for scratch. But so far, Russia does not seem to be having that kind of success.

From the early reports, it does not seem like the strikes were all that successful given the amount that Russia invested into the attacks. Part of that is due to the fact that Russia seems to have prioritized hitting a lot of different targets over thoroughness on a few critical targets. Part of that is they seemed to have had a lot of malfunctions (maybe some of that is due to Ukrainian air defenses but I am skeptical).
