KONTAN.CO.ID - KYIV - Russian missiles and drones struck nearly a dozen Ukrainian energy infrastructure facilities on Wednesday, causing serious damage at three Soviet-era thermal power plants and blackouts in multiple regions, officials said.

Ukraine's air force said it shot down 39 of 55 missiles and 20 of 21 attack drones used for the attack, which piled more pressure on the energy system more than two years after Russia launched its full-scale invasion.

"Another massive attack on our energy industry!" Energy Minister German Galushchenko wrote on the Telegram app.

Two people were injured in the Kyiv region and one was hurt in the Kirovohrad region, Interior Minister Ihor Klymenko said.

Galushchenko said power generation and transmission facilities in the Poltava, Kirovohrad, Zaporizhzhia, Lviv, Ivano-Frankivsk, and Vinnytsia regions were targeted.

Some 350 rescuers raced to minimize the damage to energy facilities, 30 homes, public transport vehicles, cars, and a fire station, the interior ministry said.

National power grid operator Ukrenergo said it was forced to introduce electricity cuts in nine regions for consumers and that it would expand them nationwide for businesses during peak evening hours until 11 p.m. (2000 GMT).

Ukrenergo CEO Volodymyr Kudrytskyi, interviewed by the Ukrainska Pravda media outlet, said electricity imports would not make up for power shortages. He said hydropower stations had also been hit, clarifying an earlier company statement omitting hydro stations from the list of affected facilities.

Power cuts for industrial users, he said, were "almost guaranteed" but interruptions for domestic users would depend on how well they reduced consumption.

"Many important power stations were damaged," he said, citing three stations operated by DTEK, Ukraine's biggest private company, as well as two hydropower stations.

"The damage is on quite a large scale. There is a significant loss of generating power, so significant that even imports of power from Europe will not cover the shortage that has been created in the energy system."

Russia's defense ministry said it struck Ukraine's military-industrial complex and energy facilities in retaliation for Kyiv's strikes on Russian energy facilities.

"As a result of the strike, Ukraine's capabilities for the output of military products, as well as the transfer of Western weapons and military equipment to the line of contact, have been significantly reduced," the ministry said.

WORLD WAR TWO ANNIVERSARY

President Volodymyr Zelenskiy noted the attacks were launched on the day Ukraine marked the end of World War Two.

"This is how the Kremlin marks the end of World War Two in Europe, with a massive strike, attempting to disrupt the lives of our people with its Nazism," he said in his nightly video address.

In an earlier online address, Zelenskiy singled out what he said was the West's limited progress in curbing Russian energy revenue and some countries that attended President Vladimir Putin's inauguration for a fifth term in the Kremlin on Tuesday.

Fighting Nazism back then, he said, was "when humanity unites, opposes Hitler, instead of buying his oil and coming to his inauguration".

Ukraine has stepped up drone attacks on Russian refineries this year despite apparent objections by the United States, trying to find a pressure point against the Kremlin whose forces are slowly advancing in the eastern Donbas region.

Ukrainian strikes on Russian refineries may have disrupted more than 15% of Russian oil refining capacity, a NATO military alliance official has said.

After pounding the energy system in the first winter of the war, Russia renewed its assault on the grid in March as Ukraine was running low on stocks of Western air defense missiles.

Prime Minister Denys Shmyhal estimated that more than 800 heating facilities had been damaged and up to 8 GW of power generation lost so far, adding the government needed $1 billion to fund repair work.

DTEK vowed to keep working to restore power at its facilities, and its CEO, Maxim Timchenko, called on Ukraine's allies to provide more air defense systems.

Officials did not name the facilities hit on Wednesday, part of a policy of wartime secrecy that Kyiv says is needed to prevent Russia from using the information for further strikes.

But Lviv governor Maksym Kozytskyi said Russia attacked a natural gas storage facility in his region in the west of the country, Radio Free Europe/Radio Liberty reported.

In central Poltava region, energy infrastructure was hit by a drone, Poltava Regional Governor Filip Pronin said.

The governors of Vinnytsia and Zaporizhzhia said critical civilian infrastructure facilities were damaged.
