At least four western provinces, from Pinar del Rio to Mayabeque, lost power early on Wednesday, officials said, though all had been reconnected to the grid within hours of the outage. Even before Wednesday's incident, much of Cuba was already experiencing daily blackouts extending as much as 20 hours or more.
Havana, once protected from the brunt of outages, now regularly faces 10 hours or more without electricity each day. Officials warned a generation shortfall - today approximately two-thirds of demand even after repairing transmission lines - means regular blackouts will continue.
Top energy officials said a main transmission line connecting Havana with the country's largest power plant in Matanzas failed around 5 a.m. (1000 GMT), but that workers had restored power to approximately 40% of the capital city by midday.
