He said the outlook has been revised after the latest Russian attack on energy facilities and a persisting significant shortfall in generation capacity.
“Meanwhile, the Russians are preparing for new attacks on the energy sector within a week,” Shmyhal said.
Urgent repairs are under way in all regions, he added. In Kyiv, more than 230 crews are working, including 40 teams from state oil and gas operator Naftogaz joining the effort recently.
In homes where central heating cannot be restored soon, electricity should be available at least 18 hours a day, Shmyhal said.
“We are stepping up our efforts with all partners to secure energy equipment,” the minister said.
“More than 30 countries are already providing support so Ukraine can get through this winter.”
Earlier the same day, Prime Minister Yulia Svyrydenko said that since the start of 2026, Ukraine’s energy sector has been hit by 217 Russian attacks.
On Feb. 3, Russia launched another massive attack on Ukrainian energy facilities, firing multiple waves of ballistic missiles, Shahed drones, Kh-22 and Kh-101 cruise missiles from strategic bombers. The heaviest strikes targeted Kyiv city and oblast, Kharkiv city and oblast, Dnipropetrovsk Oblast and Odesa Oblast, with explosions also heard in Zaporizhzhya.
In Kyiv, damage occurred in the Darnytskyi, Desnianskyi, Dniprovskyi, Pecherskyi and Shevchenkivskyi districts, with five confirmed casualties by morning.
Mayor Vitali Klitschko said infrastructure was hit, leaving the Darnytskyi and Dniprovskyi districts on the left bank mostly without heating; 1,170 apartment buildings citywide lost heating, and utility and energy crews began restoration work.
