Background on the Power Crisis in Havana

Havana, the capital city of Cuba with a population of approximately 2.1 million, has been grappling with frequent scheduled power outages of about four hours daily. However, some provinces face extended blackouts lasting up to 20 hours or even over a day. These power cuts are due to the deteriorating state of Cuba’s thermoelectric plants, fuel shortages, and a compromised national electricity grid.

Impact on Daily Life

The ongoing electricity crisis has severely affected water supply and gas services. Between October and March, Cuba experienced four widespread power outages, some lasting several days. The recent unexpected power outage on Monday morning disrupted the sleep of many Havana residents, who had to seek relief from the intense summer heat by standing on balconies or rooftops.

Details of the Unexpected Outage

The power outage on Monday was caused by a malfunction in four substations, leaving numerous zones without electricity across almost all of Havana’s municipalities. Empresa Eléctrica de La Habana, the city’s electricity company, reported the issue on their Facebook page.

Restoration of Power and Future Plans

Power was gradually restored across most municipalities a few hours after the outage, with priority given to essential water supply sources, hospitals, and socioeconomically significant centers.

Empresa Eléctrica de La Habana anticipates a peak demand of 3,700 MW during the day and predicts a shortfall of 1,862 MW at peak consumption hours.

In response to the crisis, the Cuban government initiated a large-scale solar energy generation project this year. So far, 24 photovoltaic parks using Chinese technology have been installed out of a planned total of 51 by the end of 2025.
