Ukrainian energy operator Ukrenergo warned Monday that emergency shutdowns would be applied in all regions across the country as it contends with the consequences of a new wave of Russian attacks.

"Due to the consequences of shelling… to maintain the balance between the production and consumption of electricity, a regime of emergency shutdowns will be introduced in all regions of Ukraine," Ukrenergo said on Telegram.

"In priority, electricity will be supplied to critical infrastructure facilities."

"The situation is difficult, but under control," the operator said, after Kyiv's forces announced they destroyed more than 60 out of the 70 missiles launched by Moscow.

Still, it said that "some power plants will not be able to work at full capacity for a certain time."

"Combined with the frost increasing in the next 24 hours, this will lead to a deficit of electricity in the system," it said.

Emergency repair works are ongoing, the company said.

On Monday the Russian army acknowledged "massive attack on Ukrainian military command systems and related defence, communications, energy and military facilities."

After suffering humiliating defeats during what has become the largest armed conflict in Europe since World War II, Russia began targeting Ukrainian energy infrastructure in October, causing sweeping blackouts.

Putin on Friday said Russian strikes on Ukrainian infrastructure were "inevitable".

More than 500 Ukrainian localities without power: ministry
Kyiv, Ukraine (AFP) Dec 4, 2022 –

More than 500 Ukrainian localities remained without power Sunday following weeks of Russian airstrikes on the electric grid, an interior ministry official said.

"The enemy continues to attack the country's essential infrastructure. Currently, 507 localities in eight regions of our country are cut off from electricity supplies," deputy interior minister Yevgueny Yenin told Ukrainian television.

"The Kharkiv region is the worst hit with 112 isolated villages," Yenin added.

Another 90 villages were cut off in the Donetsk and Kherson regions, he said, with others in the regions of Mykolaiv, Zaporizhzhia and Lugansk.

On Saturday, Ukrainian authorities — including Mykolaiv region governor Vitali Kim — had once again urged civilians to bear up in the face of continually deteriorating early winter conditions and regular power outages.

Repeated daily power cuts have left millions of people without heat or lighting while outside temperatures have dropped below zero Celsius (32 Fahrenheit) in recent days.

With further strikes on the network widely expected, Ukrainians fear a difficult prolonged winter as well as a flood of departures by refugees from a war now into a tenth month.

Private Ukrainian energy operator DTEK said Thursday that nearly half of Ukraine's electricity grid remains damaged after Russia began targeting Ukrainian energy facilities in October following a series of humiliating military defeats on the ground.
