Ukraine managed to maintain energy stability after last week’s Russian attacks targeting key parts of its infrastructure, Ukrainian Prime Minister Denys Shmigal said, The Guardian reports.

On Facebook, Shmigal noted that in the first three days of the week, Russia carried out up to 130 missile and drone strikes on civilian and energy facilities, especially in the capital, Kyiv.

He said repairmen were able to restore power to about 4,000 settlements and that people in Ukraine voluntarily reduced consumption by an average of 10 percent, making it easier to avoid blackouts.

“The aggressor sought to intimidate Ukrainians and paralyze the energy sector of the state. It did not achieve its goal,” said Denys Shymyhal.

Russia has announced that it is continuing airstrikes against military and energy facilities in Ukraine using high-precision, long-range weapons.

A missile seriously damaged a key energy facility in the region around Ukraine’s capital, while 10 missiles and four drones hit Zaporizhzhia in southeastern Ukraine on Saturday.

Electricity was periodically cut off in Kyiv, and fires broke out in Zaporizhzhia, but further damage to substations did not affect electricity in the city.

Evidence from the scene suggests that several rockets fired at Zaporizhzhia missed, damaging only cars and shattering windows of high-rise buildings, rather than affecting critical infrastructure.

Russia is waging a campaign to destroy Ukraine’s energy system as winter approaches, prompting the Ukrainian government in recent days to launch a nationwide effort to conserve energy.
