Special "invincibility" centres will be set up around Ukraine to provide electricity, heat, water, medicines, and internet and mobile phone connections free of charge and around the clock, Zelensky said in a video address late on Tuesday.
"If massive Russian strikes take place again and if there is an understanding that the electricity supply cannot be restored within hours, the work of 'points of invincibility' will be activated," Zelensky said, as cited by the ukrinform.net website.
He added that "all basic services will be there, including electricity, mobile communications and the internet, heat, water, and a first-aid kit. Absolutely free and 24/7."
Zelensky said last week that about 10 million people were without power across the country, with emergency blackouts ordered in some areas after days of heavy Russian bombardment of civilian infrastructure.
Ukraine's Prime Minister Denys Shmyhal said this week that some 8,500 power generator sets were being imported to Ukraine daily, the Reuters news agency reported.
The World Health Organization warned this week that hundreds of Ukrainian hospitals and healthcare facilities lacked fuel, water and electricity, according to Reuters.
"Ukraine's health system is facing its darkest days in the war so far," Hans Kluge, the WHO regional director for Europe, said in a statement after visiting Ukraine.
"Having endured more than 700 attacks, it is now also a victim of the energy crisis," Kluge added, as quoted by Reuters.
