Cuba has restored electricity nationwide, state-owned utility Union Electrica said in a social media post on Sunday, following a second island-wide blackout in a week on Friday.
The recent power outage occurred two days after authorities reconnected the system following Monday's nationwide blackout.
Fuel shortages and aging infrastructure have reportedly resulted in frequent blackouts on the island, particularly after US President Donald Trump imposed an oil blockade in January to disrupt shipments.
The US cut off Venezuela's oil exports to Cuba after the arrest of Venezuelan President Nicolas Maduro on Jan. 3, and has warned of punitive tariffs on countries shipping crude to Cuba.
"The new outage of the SEN (National Electric System), with just a few days' difference, adds tensions to the recovery but the electricians don't give up... A very complex process, under the genocidal oil blockade," according to Cuban President Miguel Diaz-Canel's translated statement on X on Sunday.
Prime Minister Manuel Marrero echoed the same sentiment about the oil blockade.
"It has been another very tough week under the impact of the energy blockade: two SEN disconnections, almost no fuel to power the plants, and several units out of service," he said in his translated post on X.
In March, 100,000 tons of Russian crude oil arrived in Cuba after the US authorized a humanitarian shipment in January, according to media outlets. However, reports indicate this volume has already been depleted.
