Cuba is experiencing a quiet energy revolution, one powered by the sun and bolstered by significant investment from China. In February 2026, the island nation achieved a record-breaking 900 megawatts (MW) of solar power generation, a milestone that underscores a dramatic shift in its energy policy and a growing reliance on renewable sources. This achievement is particularly notable given Cuba’s long-standing dependence on expensive imported fossil fuels, a situation exacerbated by decades of U.S. Sanctions.
The surge in solar energy isn’t happening in a vacuum. China has emerged as a key partner in Cuba’s renewable energy ambitions, providing not only the technology but also the financial backing to construct dozens of new solar parks. Cuba currently aims to build a total of 92 solar parks with Chinese assistance by 2028, a project that represents a substantial investment in the country’s energy infrastructure.
A Rapid Transition to Solar Power
The scale of Cuba’s recent progress is striking. In January 2025, solar power accounted for just 5.8% of the country’s total energy generation. By February 2026, that figure had jumped to 20%, according to reports. The record-breaking generation of over 800MW, followed by 900MW the next day, prompted a celebratory tweet from Cuba’s Ministry of Energy and Mines.
Beyond Large-Scale Parks: Empowering Communities
China’s support extends beyond large-scale solar farms. Recognizing the challenges of intermittency – the fact that solar power is only available during daylight hours – and the peak energy demand in Cuba (typically between 7 and 8 p.m.), China is also providing battery storage solutions. This is crucial for ensuring a reliable power supply when the sun isn’t shining.
China is supplying standalone solar power kits designed for homes and institutions not yet connected to the national grid. More than 10,000 of these kits, capable of powering basic appliances like refrigerators, fans, and televisions, have already been installed across Cuba. These kits represent a significant improvement in quality of life for many Cubans, offering access to electricity where it was previously unavailable.
Expanding Renewable Energy Sources
China’s involvement isn’t limited to solar. The country is also investing in Cuba’s wind energy potential, with wind farms already preventing several tons of carbon dioxide emissions. This broader commitment to renewable energy sources signals a long-term partnership aimed at transforming Cuba’s energy landscape.
The collaboration between Cuba and China highlights a growing trend of South-South cooperation in the realm of renewable energy. As countries around the world seek to reduce their reliance on fossil fuels and transition to cleaner energy sources, partnerships like this one will likely become increasingly common.
Looking ahead, Cuba’s success in expanding its solar capacity will depend on continued investment in battery storage and grid infrastructure. The country’s ambitious goal of constructing 92 solar parks by 2028 remains a key focus, and progress will be closely monitored by energy experts and policymakers alike. The next update on the progress of these projects is expected from the Cuban Ministry of Energy and Mines in the latter half of 2026.
