A substation failure in Havana disrupted Cuba’s national power grid, leaving large parts of the island without electricity as recovery efforts continue.
A malfunction at the Victoria de Girón substation in Havana caused widespread power outages across Cuba on July 3 after triggering a major oscillation in the National Electric System (SEN), according to Havana’s Electric Company.

The incident occurred at 20:08 local time, when the failure at the Havana substation destabilized the SEN and forced the sudden shutdown of the Renté 3 and Felton 1 generating units, two key sources of electricity for the country.
Recovery protocols were activated immediately following the disruption. The Felton unit has since been reconnected to the national grid, initially supplying 50 megawatts (MW) while gradually increasing its output. Generating units from the Energas thermal power plant have also been incorporated into the base load to help stabilize the system.
Despite these measures, Havana’s Electric Company reported that the SEN continues to operate with limited generation capacity, and power shortages remain significant across the country.

Utility crews continue restoration efforts
Electric utility crews remain deployed in multiple locations to accelerate the full restoration of service. Current operations are focused on restoring stability to the national grid while reducing the impact of the outages on the population.
Authorities expect conditions to improve over the coming hours as additional generating units are brought back online. They said updates on the recovery process will continue to be issued through official channels.
U.S. blockade compounds energy challenges
The latest power failure occurred amid Cuba’s ongoing energy constraints, which the country attributes to the tightening of the United States’ economic, commercial and financial blockade.
According to the Cuban government, the sanctions restrict access to fuel, spare parts and technology required to maintain and operate thermoelectric power plants, directly affecting the country’s capacity to provide essential public services, with the electricity sector among the hardest hit.
