Special "invincibility centres" will be set up around Ukraine to provide electricity, heat, water, internet, mobile phone connections and a pharmacy, free of charge and around the clock, President Volodymyr Zelenskiy said in his nightly video address on Tuesday.
Russian attacks have knocked out power for long periods for up to 10 million consumers at a time. Ukraine's national power grid operator said on Tuesday the damage had been colossal.
"If massive Russian strikes happen again and it's clear power will not be restored for hours, the 'invincibility centres' will go into action with all key services," Zelenskiy said.
Authorities have warned of power cuts that could affect millions of people to the end of March - the latest impact from Russia's nine-month invasion that has already killed tens of thousands, uprooted millions and pummelled the global economy.
