Cuba’s national power grid is expected to face a 1,975-megawatt shortfall in electricity service on Monday evening, as demand is forecast to exceed available generation capacity.
Cuba’s Ministry of Energy and Mines said electricity demand would reach 3,150 megawatts in the evening, while the National Electricity System’s generation capacity would stand at 1,215 megawatts. This points to a 1,935-megawatt generation gap and an expected 1,975-megawatt shortfall in electricity service.

Morning demand also exceeded generation
At 6 a.m. on Monday, available generation was recorded at 1,030 megawatts, while demand stood at 2,650 megawatts. Ministry data showed that 1,590 megawatts of electricity service were expected to be affected at that time.
The forecast came three days after Cuba’s national power grid completely collapsed. The grid was reconnected on Saturday evening, but generation capacity remained insufficient to meet electricity demand.

Breakdowns and maintenance limit generation
The collapse on September 18 was at least the sixth nationwide power outage reported in Cuba this year. The government said the problem began with failures in transmission lines and subsequently spread across the country.
Even after the grid was brought back online, numerous generating units remained out of service because of breakdowns and maintenance issues. This continued to constrain electricity generation.
Aging power infrastructure, fuel shortages, equipment failures and limited generation capacity are among the main causes of Cuba’s electricity shortfall. Restrictions on fuel supplies and access to equipment and spare parts are also deepening the energy crisis.
Havana blames measures imposed by the United States for the worsening crisis. Washington, meanwhile, attributes Cuba’s economic problems to the government’s policies.
Authorities expect supply to remain well below demand during the hours when daily consumption reaches its highest levels, with significant outages continuing nationwide. Planned power cuts remain widespread as Cuba works to stabilize the national grid and restore generation capacity.
