**Deck**: Russian drone strikes overnight damaged railway and power infrastructure across Ukraine, hit a thermal power plant that halted electricity generation, and left parts of Rivne and more than 900 communities in Zhytomyr without power, even though Ukraine says it intercepted most of the incoming drones.

Large parts of Ukraine’s energy and transport network were hit overnight, leaving new blackouts and disrupted infrastructure despite what officials describe as a high rate of drone interceptions.

Ukraine’s military said air defenses shot down or suppressed 140 of 176 drones launched in the latest wave. Even so, there were recorded impacts at 19 locations, and debris from downed drones fell on 13 more, underscoring how the sheer number of drones can still inflict damage.

According to Ukrainian channels and officials, reported targets included railway infrastructure in Poltava, power lines in Poltava region, an energy facility in Dnipro, the cable-stayed bridge in Zaporizhzhia, an industrial enterprise in Khmelnytskyi, and energy facilities in Vinnytsia and Rivne regions. There were also reports of a strike on a thermal power plant, which some described as likely belonging to a private energy company.

In a separate statement, the company said one of its thermal power stations came under massive Russian fire and stopped generating electricity. It reported significant damage to equipment and said its thermal power plants have been attacked more than 230 times since the full-scale invasion began. Losing a plant reduces the grid’s ability to cover demand, particularly during peak hours.

Regional authorities outlined the impact by Friday morning. Officials in Rivne region reported that parts of the region were without electricity because of the strikes. In Zhytomyr region, more than 900 settlements remained cut off from power. That affects homes, small clinics, schools, and local businesses just as seasonal temperatures start to fall.

The overnight attacks focused on central and western regions that are far from the front line. Explosions were reported in multiple locations in Vinnytsia region—Bershad, Vapniarka, Haisyn, Zhmerynka, Pohrebyshche, Kozyatyn and Vinnytsia city—as well as in Khmelnytskyi city, Shepetivka and other settlements. Hitting these nodes shows that critical infrastructure across the country remains exposed.

Damage to tracks and power lines in Poltava can slow military logistics, grain exports, and civilian passenger trains. Each destroyed transformer or generator adds to a constant repair effort for Ukraine’s energy workers, who face the risk of having to fix equipment under renewed fire.

The drone swarms serve several Russian objectives at once: they force Ukraine to use up air defense munitions on relatively inexpensive unmanned systems, test coverage around bridges and power facilities, and impose a rolling cost on civilians. Even when most drones are intercepted, the ones that get through can leave substations burned, tram lines stopped, and residential areas in darkness.

Ukrainian officials say they are dispersing power generation, repairing damaged lines quickly, and seeking more advanced air defense systems and electronic-warfare tools to counter jet-powered drones such as the “Geran-4” and “Geran-5” models reported in the night’s attacks. Each night of mass launches tests how long those defenses and repair crews can keep up.

Key signs to watch next include how fast operators can restore generation at the damaged thermal power plant, whether outages in Rivne and Zhytomyr shrink or spread in coming days, and whether Russia repeats large-scale drone strikes as temperatures drop and demand for heating grows.
