It depends. Repairing a "hydro" (using Malopox terms) is expensive, repairing some "distribution nodes (using Arestovich terms, what a comparison) is not. As long as Ukrainian nuclear plants are on and kicking, Ukraine is somewhat fine. Meanwhile Belarus has put "B" (or Cyrillic
"W" as Wagner (?), there are several thousands of Wagnerites doing training job in the middle of potato fields of the former Soviet Republic) sign to their MRAP's and tanks at the border.
Dnieper hydro is allegedly being repaired. Kiev hydro was just taken out.
Transmission lines are relatively easy to repair, however high voltage (750kv) transformers are in short supply globally due to energy transition efforts and if those are damaged in Ukraine it can take months to source a replacement.
Ukraine has reportedly ca 14gw of generation capacity left (ca 8gw through 9 nuclear reactors at 3 power plants it still controls, rest through minor hydro/solar/wind, leftover gas peakers and coal stations) which needs to be transmitted via 750kv lines and then downvolted to your 220v consumer specs. If transformers are out - nukes have to be throttled.
They also have interconnectors with Poland / Moldova (Romania ultimately) / Hungary and rely on those heavily, however Romanian nuclear has been suffering outages at Cernavoda nuclear reactor lately, with the latest unplanned outage happening few days ago (https://economedia.ro/breaking-avarie-la-un-reactor-al-centralei-nucleare-cernavoda-in-plina-canicula-hidroelectrica-isi-creste-rapid-productia-ca-sa-acopere-deficitul-de-productie.html)
Thick lines are 750kv transmission grids. Vinnitsa substation was targeted again so now they have to scramble to rejig surviving equipment to continue transmitting with the remaining network.
