Cuba Starts Restoring Power After Partial Grid Collapse Darkens Havana

A transmission line failure underscores a fuel-starved, fragile power system that has produced marathon blackouts for months.

Overview

  • Top energy official Lazaro Guerra said a main line linking Havana to the Matanzas power plant failed around 5 a.m. local time.
  • Power began coming back by mid-morning in parts of Havana and Mayabeque as crews worked to raise generation and reconnect customers.
  • At least four western provinces from Pinar del Rio to Mayabeque lost electricity, with hospitals and some hotels operating on generators.
  • Mobile service was intermittent and street and traffic lights were out across the capital during the outage.
  • Crude and fuel imports in January through October 2025 fell by more than one-third from a year earlier as Mexico and Venezuela reduced shipments, worsening shortages tied to aging plants and hurricane damage.
