Russia damaged the Trypillia power plant and forced emergency blackouts in Kyiv on September 30 in its largest combined strike on Ukraine's grid since the last heating season, officials said.

"Since the summer, there has been practically no day when the enemy has not attacked energy infrastructure. But such a massive and combined attack has occurred for the first time since the end of the last heating season," Prime Minister Serhii Koretskyi said, the Kyiv Independent reported.

Ukraine's Air Force said Russia launched 188 attack drones, 86 of them jet-powered, as well as Zircon and Onyx anti-ship missiles and Iskander-M and S-400 ballistic missiles overnight, and that five missiles and 155 drones were shot down or suppressed, Ukrinform reported. It recorded hits at 18 locations. State generating company Centrenergo said equipment at the Trypillia thermal power plant in the Kyiv region was damaged and withheld the extent for security reasons.

Missile alerts cost Ukraine an estimated $45mn for every hour they force businesses to stop, and Russian attacks have caused about $10bn of damage to fixed assets this year, Economy Minister Oleksandr Kravchenko told the Guardian, the Kyiv Independent reported. Steel plants, warehouses, logistics hubs and data centres have all been hit, he said.

The attacks continued overnight into October 1. The Air Force said Russia launched 107 drones, 63 of them jet-powered, from 18:00 on September 30, that 87 had been downed by 08:00 and that hits were recorded at 11 locations while the attack was still under way, Interfax-Ukraine reported.

Russia hit Ukraine's grid with what Kyiv called its biggest combined strike since the last heating season and a new weapon built to cut power lines, while Russia's defence ministry reported Ukrainian drones over 19 regions and Ukraine's General Staff claimed hits on depots in occupied territory. Moscow warned European arms makers they were targets, as Estonia pressed its case over the Milrem arson.

The ledgers

The running ledgers are kept as six public spreadsheets at permanent addresses. The first three are non-exhaustive, every row is sourced, and where only one side has spoken the row says so. Defence ministry figures are recorded as claims, and in the sabotage ledger attribution is given exactly as the authorities state it and no further. The fourth tracks what has happened to Ukraine's steel, iron ore, coke, ferroalloy and non-ferrous plants since 2021, grouped by owner. The fifth, started on September 27, follows strikes on data centres, telecoms, media and research sites.
