Cuba suffers second nationwide blackout, energy supply under severe strain

Cuba has recently experienced its second nationwide blackout, with two large‑scale outages occurring within a span of five days. The Cuban National Electricity Company (UNE) said that fuel shortages, aging power plants, and ongoing power rationing were the main reasons for the grid’s collapse.

Cuba is an island nation in the Caribbean that includes the main island and 4,195 smaller islands, coral reefs, and islets. It lies at the junction of the Caribbean Sea, the Gulf of Mexico, and the Atlantic Ocean. To the east it borders the Yucatán Peninsula; to the south it is adjacent to Florida and the Bahamas; to the west it faces Hispaniola Island; and to the north it neighbors Jamaica and the Cayman Islands. Havana, with a population of about 11 million, is Cuba’s largest city and capital. It is the third‑largest population in the Caribbean after Haiti and the Dominican Republic, and it is also the largest country by area in the region.

Cuba’s history dates back to around 4,000 BC, when the Hatabé and Taíno peoples inhabited the land. In the 15th century Spanish colonists arrived, and the population was primarily composed of indigenous peoples, Spanish settlers, and African slaves. Cuba remained part of the Spanish Empire until the Spanish‑American War of 1898, after which it declared independence.

In recent years, Cuba’s economy has faced numerous challenges, including fuel shortages, aging infrastructure, and U.S. economic sanctions. The government has been working to improve the economy and infrastructure, but progress has been slow. The recent power outages have highlighted the country’s energy difficulties, underscoring the need for new solutions to ensure a stable supply.

The blackouts have also affected Cuba’s medical and transportation systems, with many hospitals and transit networks disrupted. In response, the government has activated emergency measures, mobilizing backup power sources and repairing damaged grid facilities. Nevertheless, long‑term solutions are required, including upgrading infrastructure and diversifying energy sources.

For Taiwan, Cuba’s experience underscores the importance of energy security. As an island nation, Taiwan’s economic and social development depends on a reliable energy supply. Cuba’s lessons could serve as a reference for Taiwan, which must continue to upgrade its energy infrastructure, diversify its supply, and guarantee stability. Moreover, the outages remind us that regional energy challenges demand international cooperation and support, an area where Taiwan could play a constructive role.
