Cuba's power grid collapses, leaving it without electricity for the third time in March

Cuba’s power grid collapsed on March 21, leaving the country without electricity for a third time in March as the communist government battles with a decaying infrastructure and a US-imposed oil blockade.

The state-owned Cuban Electric Union reported a total blackout across the island without giving a cause for the outage.

Authorities said they were working to restore power.
Power outages, whether nationwide or regional, have become relatively common in the last two years due to breakdowns in the aging infrastructure. The breakdowns are compounded by daily blackouts of up to 12 hours caused by fuel shortages, which also destabilise the system.
The last nationwide blackout occurred on March 16. The March 21 outage was the second in the past week and the third in March.

The blackouts have a significant impact on the population, whose lives are disrupted by reduced work hours, lack of electricity for cooking, and food spoilage when refrigerators stop working, among many other consequences.

President Miguel Díaz-Canel has said the island has not received oil from foreign suppliers for three months. Cuba produces barely 40% of the fuel it needs to power its economy.

Cuba’s aging grid has drastically eroded in recent years, leading to daily outages and an increase in islandwide blackouts. But the government also has blamed its woes on a US energy blockade after US President Donald Trump in January warned of tariffs on any country that sells or provides oil to Cuba. The Trump administration is demanding that Cuba release political prisoners and move toward political and economic liberalisation in return for lifting sanctions. Trump has raised the possibility of a “friendly takeover of Cuba”.

Cuba’s Ministry of Energy and Mines said a total disconnection of the National Electric System took place, the second nationwide blackout reported in a week, according to a statement posted on social media on March 21.

The ministry says protocols to restore electricity service across the country were being implemented.
