Russia has found a way to cut Ukraine’s power lines that no repair crew can undo. A unique power transmission tower that a Russian drone cut down at the Dnipro River crossing in Kyiv cannot be restored,  Ukrenergo board chairman Vitaliy Zaichenko says, as the grid operator rushes to build alternative ways to keep electricity flowing, Interfax reports.

Russia has spent the war trying to switch off Ukraine’s lights. Now, it is widening the campaign before winter with a new tactic: drones that slice through the steel towers carrying high-voltage lines.

“Everyone has seen the video showing the destruction of one of the unique power transmission towers at the crossing over the Dnipro in Kyiv. It was severed, and it is impossible to restore it,” Zaichenko continues.

He adds that now the company is developing new technical solutions "on the fly, and very fast." It will start the procedures for those solutions from 15 October, he notes. Russia’s use of drones able to sever metal towers is a new and serious challenge for Ukraine’s power engineers.

Zaichenko did not say when the tower was hit. On 30 September, Russia first used a jet-powered drone carrying a 40-kilogram charge built to cut steel towers, and that evening an eyewitness filmed one striking a power line tower in Kyiv, which cut electricity in parts of three districts, Informator reported.

When the spare parts are as scarce as the targets are plentiful

Rebuilding is colliding with a global shortage. Ukrenergo faces serious difficulties getting backup equipment, Zaichenko explains, because the whole world’s energy system is expanding at once and everyone needs the same hardware.

“There is a real problem with equipment. The global power system is expanding, and everyone needs energy equipment. There is a tough queue,” Zaichenko says.

Ukraine has faced such challenges since August 2026, when Russia began launching its jet-powered drones. Kyiv still has no effective solution against them and relies more on a mix of air defenses, such as automated turrets and interceptor drones.

Kyiv has also engaged over 100 private air defense system brigades to protect its enterprises in the ranks of the Ukrainian Air Forces.

Ukraine has found the US component in a Russian jet-powered drone targeting civilians, supermarkets, medical warehouses, and bridges. According to its Defense Intelligence, the new weapon contains a PNI5GA magneto-inductive sensor made by the US company PNI Sensor.

The US-made navigation component adds to evidence that Western technology continues to appear in Russia's strike drones. HUR had already identified US-made chips in the Geran-4 in May, but the newly reported PNI5GA is a navigation sensor in a modified version of the drone that Institute for the Study of War (ISW) says Russia may seek to field ahead of winter.

A Russian engine replaces the Chinese one

Russia has also replaced the drone's Chinese-made Telefly turbojet engine with a Russian-made equivalent produced in Alabuga. Russia is using the Alabuga zone to bring more of its drone production home rather than importing Iranian or Chinese parts, according to the ISW.

"The remaining electronic units and components are unchanged and identical to those used in previous Geran UAVs," HUR said.

What the warhead is built to cut

The modified drone also carries a specialized KRSN warhead designed to cut through bridge structures and power-line supports. Presidential adviser Serhii Beskrestnov described the warhead on 30 September, saying it consists of a 40-kilogram main charge and four strike modules. Its warhead is meant to destroy hardened targets made of steel and concrete and to damage cable-stayed bridges.

Russia has stepped up strikes on Kyiv's Northern and Southern bridges across the Dnipro in recent days with such drones.

However, Russia may try to field more resilient and more dangerous versions of its strike drones before Ukraine has effective countermeasures in place. Russia could use them to degrade Ukraine's energy infrastructure and logistics ahead of a winter strike campaign that it said will very likely be brutal.

More than a decade ago, a group of snipers shot up an electrical substation in Silicon Valley, striking power transformers and disabling the substation for nearly a month. The shooters were never identified; similar substation shootings, some by neo-Nazis, have taken place since. The longer Christopher Cox studies the American power grid—looking at aging infrastructure and ongoing transformer shortages, specialized manufacturing and rising demand, the massive energy consumption of data centers and whiplash usage of large language models—the more vulnerable it seems. “Somehow, we’ve made the industrial equivalent of a Fabergé egg the linchpin of our civilization,” Cox writes. “What would happen if someone started breaking them?”

The hope of restoring the grid would fade as fossil fuel supplies were exhausted, because so many utilities rely on them to “black-start” their generating units. A 2010 report called “High-Impact, Low-Frequency Event Risk to the North American Bulk Power System,” prepared by the Energy Department and NERC, condensed the entire disaster movie that would follow into a single paragraph: “The supply of food, water and fuel would degrade within days. The facile communication of information to the general population would be greatly complicated by the loss of cellphones, internet access and television. The economy would virtually shut down as electronic transactions could no longer be processed. After several days, widespread social unrest and confusion would ensue.” Thirsty, starved, dirty and surrounded by the useless machines we once depended on, we would be lucky if our misery ended at “confusion.”
