Russian strikes cripple Ukraine’s power grid ahead of Geneva talks

Russian forces launched a coordinated assault on Ukraine’s energy infrastructure overnight into Feb. 17, cutting power and heating to large parts of the country and killing three energy workers, Ukrainian officials said. The strikes hit high-voltage transmission lines, power plants, substations and transmission equipment hours before a U.S.-backed trilateral round of talks in Geneva, complicating both relief efforts and diplomatic negotiations.

Ukrainian authorities said the attacks affected 12 regions and left “tens of thousands” without electricity and heat. Deputy Energy Minister Artem Nekrasov reported that homes in five regions had suffered power cuts and that heating supplies were disrupted in Odesa and Sumy. The three workers were killed when a Russian drone struck their car near the Sloviansk power plant in a frontline area, officials said.

Denys Shmyhal, a senior Ukrainian official, described the strikes as striking the backbone of the grid by damaging high-voltage transmission lines and critical generation and distribution nodes. Operators at nuclear plants were forced to “unload” reactor units, reducing output or shutting units as a precaution when external supplies became unstable, officials said, raising additional safety concerns and operational strains on the power system.

Ukrenergo, the state transmission operator, warned that “Due to the damage caused by the enemy, emergency outages have been applied in most regions,” signaling a broad geographic response to localized hits. The private energy company DTEK said infrastructure supplying the strategic Black Sea port of Odesa suffered “incredibly serious” damage and warned that “Repairs will take a long time to restore the equipment to working order.”

Kyiv responded to the grid disruption by seeking cross-border assistance. Shmyhal said the damage prompted a request for emergency electricity support from Poland to shore up supplies while repairs proceed. The outage cascade and the need for imports underline the fragility of Ukraine’s grid under sustained attack and the reliance on regional interconnections as a buffer during crises.

President Volodymyr Zelenskiy condemned the strikes on social media, writing that “It was a combined strike, specially calculated to cause as much damage as possible to our energy sector,” and calling for diplomacy to be backed by “justice and strength.” He added on social platforms that “Every day, Russia could choose real diplomacy, but it chooses new strikes” and that “Moscow must be deprived of the ability to use the cold as leverage against Ukraine.”

The timing of the bombardment, hours before the Geneva talks scheduled for Feb. 17–18 and at which Vladimir Medinsky was named to lead the Russian delegation, is likely to harden Kyiv’s negotiating stance and complicate Western efforts to mediate. Strategically, targeting energy infrastructure in winter imposes immediate humanitarian costs and aims to create political pressure by disrupting heat and power when demand is highest.

Market and policy implications are immediate. Emergency imports from Poland will tighten regional cross-border capacities and could push short-term wholesale electricity prices higher in neighboring markets. Repeated attacks on generation and transmission also increase the financial burden of reconstruction for Ukraine and heighten calls among Western policymakers for additional air defenses, grid-hardening investment, and contingency arrangements for energy supplies during negotiations.

The strikes continue a pattern of winter attacks on critical infrastructure since the full-scale invasion began in 2022, exacerbating civilian hardship and testing international support mechanisms. Key gaps remain in public reporting: a full list of affected regions, the detailed status of individual power plants and nuclear units, and precise weapon counts. Ukrainian authorities and international partners will need to provide that operational data to guide repairs, humanitarian aid and policy responses.
