Cuba’s electricity system has come under intense pressure in recent years, shaped by decades of US sanctions, an ageing oil-based grid, and chronic fuel shortages due to restrictions on imports from Russia and Venezuela – a function of the US’s illegal and suffocating blockade. With peak demand reaching 2,500 MW and shortfalls of up to 1,300 MW, widespread daytime power cuts have caused significant disruptions to daily life, from water pumping to refrigeration. While emergency repairs and energy-efficiency measures—supported partly by Russian engineering—have stabilised around 850 MW, the fundamental solution being pursued is based on restructuring Cuba’s energy matrix toward renewable sources.
In this project, China has emerged as Cuba’s most vital partner. In 2024–25, China helped launch an ambitious programme of 55 solar farms capable of supplying 1,200 MW by the end of the year, with 37 more planned by 2028. This collaboration directly addresses Cuba’s shortfalls and reduces its dependence on imported fossil fuels. Chinese assistance also includes refurbishing wind turbines and supplying distributed-generation equipment, spare parts, and thousands of photovoltaic systems for isolated homes.
A recent landmark inauguration in Guanajay of the Mártires de Barbados II solar park symbolises this deepening partnership. The project, part of a Chinese donation that will add 120 MW to Cuba’s grid, was completed in record time thanks to tight coordination between Chinese and Cuban companies. The second phase, already underway, will add another 85 MW plus battery storage. Addressing the inauguration, Chinese Ambassador Hua Xin stated that these efforts embody China’s commitment to Cuba’s sustainable development and to building a China–Cuba community with a shared future. Cuban officials echoed this sentiment, emphasising that the new solar parks will save tens of thousands of tons of imported fuel annually, cut nearly 50,000 tons of CO₂ emissions, and significantly reduce service disruptions.
Against a backdrop of US hostility and sanctions, China’s steady, practical support is helping Cuba advance toward energy sovereignty, economic resilience, and a cleaner, more secure future.

China’s cooperation with Cuba in the energy sector remains strong and steady
Guanajay, Artemisa.– “China’s cooperation with Cuba in the energy sector remains strong and steady, from ongoing projects, such as equipment and spare parts for distributed generation, the 5,000 photovoltaic systems for isolated homes, and the installation of other solar photovoltaic parks (PSFV) with a total capacity of 85 MW, to the next project to install another 200 MW and the new 5,000 photovoltaic systems for isolated homes.”
