Four provinces remain disconnected from the National Electric System.

Four Cuban provinces remain disconnected from the Cuban Electrical System, three of them in a state of cyclone alert due to the proximity and imminent passage of Hurricane Oscar through their territories.

Guantánamo, Santiago de Cuba, Granma, and Pinar del Río continue without electricity, according to a graph shared by the state-run media Cubadebate.

At one in the afternoon this Sunday, the national electrical system (SEN) was connected from Mariel to Holguín, with a relief after the entry of the Antonio Guiteras Thermoelectric Power Plant, as well as a turbine from Energás Boca de Jaruco and the two floating power plants in Havana, said the Electric Company in a message on Facebook.

In Santiago de Cuba, hours after the enthusiastic announcement of the commissioning of generation block No. 3 of the CTE Antonio Maceo, also known as Rente, the situation took an unexpected turn due to a malfunction in the unit that led to the collapse of the system. As a consequence, there was a failure of a microsystem that affected the provinces of Santiago de Cuba and Guantánamo, leaving them without electric service.

However, this entity assured that "the electrical grid is more intact and there is more reliability at this moment," although many Cuban families still remain without electricity, accumulating up to 72 hours without the service.

In Havana, the capital of the country, it was reported that more than 216,000 customers, belonging to 67 circuits, have electrical service.

While in other provinces they continue to take alternatives to address the electrical collapse on the island, a situation that has been occurring for years due to the lack of an investment process in the thermoelectric units.

The situation worsens with the impending impact of Hurricane Oscar in eastern Cuba, as a category one cyclone on the Saffir-Simpson scale.

According to a statement from the Cuban Civil Defense, precipitation accumulations are expected to reach between 100 and 200 millimeters in the next 24 hours, while the strength of the winds will gradually increase.

Oscar's entry into Cuban territory is expected at some point in the provinces of Holguín and Guantánamo, which is why the authorities are cautious regarding the improvement of electrical service.
