Cuba's Nationwide Blackout Amid China's Pledge for Solar Energy Projects

Tuesday, March 17, 2026 by Edward Lopez

In the wake of a severe nationwide blackout that has further strained Cuba's crumbling electrical infrastructure, China's ambassador to Havana, Hua Xin, has vowed to expand his country's collaboration with Cuba in critical sectors such as energy, food, and technology.

During a press briefing reported by the state-run Caribe channel, the Chinese diplomat emphasized that Beijing will continue to support energy projects in Cuba, focusing on the development of renewable energies like solar photovoltaics. This initiative aims to alleviate the dire electrical situation plaguing the island.

The announcement comes at an especially challenging time. On Monday, Cuba experienced a complete disconnection from the National Electric System (SEN), confirmed by the Unión Eléctrica (UNE), plunging the island into widespread darkness following days of severe service disruptions.

China's Renewable Energy Projects

Ambassador Hua explained that China intends to accelerate the implementation of energy cooperation projects, including solar parks and photovoltaic systems aimed at bolstering electric generation. He highlighted initiatives involving projects of tens of megawatts and thousands of solar systems, indicating that this collaboration will continue to grow.

“More will come,” he assured in response to journalists' inquiries about potential new investments in Cuba's energy sector.

China's Commitment and Political Support

The Chinese representative also pointed out his country's leadership in clean energy generation and energy storage technology development, noting that these capabilities are part of the projects Beijing is eager to share with Cuba.

In his remarks, Hua reiterated China's political support for the Cuban government and condemned U.S. sanctions, declaring that China "firmly opposes" coercive measures against the island and will continue cooperation in fields like biotechnology, telecommunications, and food production.

Ongoing Energy Crisis in Cuba

The internal energy crisis in Cuba continues to worsen. Before the complete blackout, the system was already under immense pressure: as of 6:00 a.m. on Monday, the available electricity was a mere 1,140 megawatts against a demand of 2,347, according to official UNE data.

This collapse of the SEN occurred amid the structural fragility of the electrical system, beset by aging thermoelectric plants, fuel shortages, and frequent breakdowns.

Though the Cuban government has recently aimed to expand solar generation with new photovoltaic parks, these efforts have not prevented the daily blackouts affecting much of the country. With the electrical system once again on the brink, authorities hope the energy projects undertaken with China can help stabilize a grid that many Cubans feel is teetering on the edge of collapse.

FAQs on Cuba's Energy Crisis and China's Involvement

What is the current state of Cuba's energy crisis?

Cuba's energy crisis is severe, with aging infrastructure, fuel shortages, and frequent power outages. The recent complete blackout of the National Electric System highlights the system's fragility.

How is China supporting Cuba's energy sector?

China is expanding its cooperation with Cuba by implementing renewable energy projects, particularly solar photovoltaic systems, to enhance the island's electricity generation capacity.

What are the potential benefits of China's solar projects in Cuba?

The solar projects could help stabilize Cuba's electrical grid, reduce reliance on aging thermoelectric plants, and mitigate the frequency of blackouts.
