The Japanese government has committed $6.5 million to implement solar energy systems in hospitals across various Cuban provinces. This initiative aims to ensure medical services remain operational during the frequent power outages plaguing the island, as announced by the United Nations Development Program (UNDP) on May 5th.
An official ceremony in Havana sealed the agreement, with representatives from Cuba, Japan, and the UN present to mark the occasion.
Solar Solutions for Healthcare Challenges
This two-year project will involve the installation of solar panels, power conditioners, and storage batteries tailored to meet the critical needs of each healthcare facility.
The Cuban Ministry of Public Health (MINSAP) will spearhead the efforts in collaboration with the UNDP, the Ministry of Energy and Mines, the Electric Union, and local authorities.
Addressing an Urgent Power Crisis
The UNDP bluntly addressed the severity of the issue at hand: “Hospitals are among the most affected facilities, with disruptions threatening the continuity of essential medical services, the operation of life-saving equipment, and the preservation of medications and vaccines.”
Cuba is grappling with an unprecedented energy crisis. The National Electric System has experienced at least seven total breakdowns in the past 18 months, including two within the same week in March 2026: on March 16, lasting 29 hours and 29 minutes, and again on March 21.
In April 2026, the generation deficit reached a staggering 1,945 MW, leaving over 55% of the nation without power simultaneously.
Impact on Healthcare Services
The consequences for healthcare have been dire. In April, Santiago de Cuba's Provincial Hospital evacuated 12 ICU patients due to a blackout, and by March 31, more than 96,000 patients, including 11,193 children, were awaiting surgery throughout the island.
Japan's collaboration with Cuba in energy and healthcare is not new. Through the Japan International Cooperation Agency (JICA), Japan funded a 10 MW lithium-ion battery system in the Isle of Youth, completed in August 2025, which enabled the municipality to achieve 20% renewable energy generation.
In 2023, JICA also donated medical equipment worth five million dollars to Cuban hospitals, including 13 mobile X-ray units, 44 ultrasound machines, and 1,000 aspirators.
The root cause of this emergency is the collapse of an aging electrical infrastructure, deteriorated over decades of dictatorial rule, with outdated thermoelectric plants and a heavy reliance on Venezuelan oil that has gradually diminished.
The UNDP, overseeing more than 40 cooperative projects in Cuba, anticipates that the photovoltaic systems will ultimately benefit 2.6 million patients and 27,500 healthcare workers once the project is completed.
