Russian strikes hit three major power plants in the Kyiv region on Tuesday night, as well as a substation that transfers electricity from two nuclear plants to the capital.

Missiles and drones also struck power plants in Kyiv and Kharkiv this week. Rolling blackouts and water outages have accompanied the attacks, which appear to resemble a reported Russian assessment of how to disrupt life in Ukrainian cities.

Ukrainian intelligence said it intercepted the assessment from Russia last month. The document describes potential effects ranging from power cuts to a complete loss of water supply, and identifies vulnerable grid facilities, including switchyards at nuclear plants. Its author is not named, but European officials familiar with it consider it likely to have come from analysts linked to Russia’s military or intelligence agencies.

The strikes continued after Donald Trump unilaterally declared an energy ceasefire between Moscow and Kyiv last week.
