Cuba Faces Sixth Nationwide Blackout This Year as Power Grid Collapses Again

Ongoing Energy Crisis Hits Cuba

According to Рубрика — Суспільство: On September 18, Cuba experienced yet another failure in its power grid, plunging millions into darkness for at least the sixth time since the start of 2026. The Ministry of Energy and Mines reported a major outage caused by damage to electrical transmission lines in the western part of the island. This disruption primarily affected Matanzas province and eastern regions of Cuba. In Havana, where approximately 862,000 customers reside, only 5% had their electricity restored before nightfall.

External Pressures Exacerbate Power Shortages

The island’s energy woes have worsened due to U.S. restrictions on oil imports imposed earlier this year. The United States effectively halted oil shipments to Cuba by imposing additional tariffs on countries supplying the island. In late January 2026, then-President Donald Trump declared a national emergency concerning Cuba, accusing the government of collaborating with Russia, China, Iran, Hamas, and Hezbollah. Following this, Cuba condemned U.S. operations in Venezuela and endured blackouts lasting over 30 continuous hours.

In response, local microgrids were established in the provinces of Camagüey, Pinar del Río, and Granma to partially restore power. Electricity was also selectively reinstated for hospitals and other critical facilities. Cuban President Miguel Díaz-Canel acknowledged the growing instability, stating,

“the energy situation on the island is becoming increasingly precarious.”

These developments highlight the severe challenges Cuba faces amid restricted energy supplies and mounting international pressure. The power outages stem not only from internal infrastructure weaknesses but also from economic sanctions that severely limit the country’s access to vital resources.

The escalating energy instability threatens Cuba’s economy and the well-being of its population, as consistent electricity is essential for key services like healthcare. Moreover, this crisis reflects the heightened tensions between Cuba and the United States, with potential implications for the nation’s political and social stability.

The ongoing energy crisis in Cuba is not isolated, as evidenced by a recent massive blackout that left millions without power. This situation underscores the dire implications of the country's failing energy infrastructure and the exacerbating effects of external pressures, further complicating the daily lives of Cubans grappling with frequent outages.
