Millions lose power as Cuba hit by fifth blackout in less than a year | Energy News

The island of 10 million’s worsening energy and economic crisis has led to a series of ‘frustrating’ grid collapses.

Another total electricity blackout has struck Cuba, the latest in a string of grid collapses that have rocked the island of 10 million over the past year.

The island-wide outage, which hit just after 9am local time on Wednesday, is believed to be linked to a malfunction at one of Cuba’s largest thermoelectric plants, the Ministry of Energy and Mines said.

The ministry said crews had been dispatched to build a microsystem capable of providing basic services, and were prioritising the return of electricity to essential sites such as hospitals and food production plants.

Prime Minister Manuel Marrero also made an appearance on state TV at Cuba’s state-run power company, asking Cubans for their trust and promising that electricity would be restored gradually.

Cuba’s worsening economic and energy crisis has led to repeated daily blackouts and full grid outages. In March, a breakdown at a substation in the capital, Havana, led to rolling blackouts across the island, with three more blackouts occurring late last year.

Across Havana, traffic lights were down as people scurried around to buy groceries and basic goods before dark. Pumps supplying the capital’s apartments with water rely on electricity.

Havana resident Danai Hernandez told Al Jazeera she had left work to prepare her home for the blackout. “We just have to wait. There’s no other choice,” she said.

“We’re cooking with wood and charcoal, so we have to adjust our schedules,” resident Ernesto Gutierrez told Al Jazeera. “It’s complicated, stressful, and frustrating, too.”

Cuba’s energy supply crisis has deteriorated in recent years because of US sanctions, which prevent it from holding sufficient foreign currency to upgrade or repair fast-ageing plants that have been in use for more than three decades.

Havana has tried to fill the gap by renting floating Turkish power ships and installing Chinese-funded solar parks. Some wealthier families have installed rechargeable devices and solar panels in their homes.

Still, the blackouts have prompted rare protests, with crowds flooding the second-largest city of Santiago last year.
