Cuba Restores Power After 29-Hour Blackout Amid US Oil Blockade

On March 17, 2026, Cuba successfully restored its power grid, which had suffered a nationwide blackout lasting over 29 hours. This disruption affected the approximately 10 million inhabitants on the island, forcing many to rely on portable lighting and causing widespread discomfort as daily life was interrupted.

The blackout was attributed to a collapse of the national electricity system, reported as a "total disconnection" by the Ministry of Energy and Mines. Officials worked diligently to restore power, successfully bringing the Antonio Guiteras power plant, Cuba's largest oil-fired facility, back online by 6:11 PM local time (2211 GMT). However, energy officials cautioned that generation remains insufficient, suggesting that power shortages may persist despite the restoration efforts.

The situation has been compounded by the U.S. oil blockade, which has resulted in severe constraints on Cuba's fuel supply, particularly following U.S. sanctions that targeted oil shipments from Venezuela, Cuba’s primary oil supplier. President Donald Trump recently intensified rhetoric against Cuba, declaring he could "do anything" regarding the island, while U.S. officials criticized the Cuban government's handling of the energy crisis, labeling the blackouts as a result of the regime's incompetence.

Cuban President Miguel Díaz-Canel responded strongly, denouncing U.S. threats and reaffirming the nation's resilience against external pressures. He asserted that the ongoing blockade attempts to undermine Cuba's sovereignty and economic stability.

Many residents, including those in Havana, reported daily blackouts lasting 16 hours or more even before the latest crisis, highlighting a worsening energy situation that has led to frustration and unrest. Local individuals have expressed the impact of these outages on basic needs such as food preservation and access to clean water, emphasizing the stress caused by such instability.

Efforts to enhance energy generation are ongoing, with discussions involving the U.S. aimed at negotiating a resolution to the crisis, marking some of the most acute tensions between the two nations since 1959. However, despite these diplomatic attempts, the fundamental challenges of energy production and lack of sufficient fuel continue to threaten the stability of everyday life for Cubans.
