On a Tuesday morning in Havana, a single substation failure at Apollo set off a cascade of blackouts across Cuba's capital, touching seven substations and silencing generation units at two major thermal power plants. Cuba's national electric utility moved with urgency to restore order, bringing nearly all affected substations back online through careful, sequenced recovery. The incident did not collapse the grid entirely — the national system's interconnection held — but it laid bare the quiet fragility of infrastructure long strained by age and chronic shortage.
