Following three days of nationwide blackouts caused by the collapse of Cuba’s electrical system, power was restored to most of Havana on Monday, after Cuban authorities gave up efforts to restore the entire grid for now and opted to try to hook up individual regions around the country.

School is out and all non-essential work places ordered closed until Thursday after the island’s power grid collapsed.

By Monday afternoon, around 89 percent of customers in the capital had power again, however many residents outside Havana remained without electricity, according to the authorities.
