Mass blackout: The electrical microsystem created in Santiago de Cuba has collapsed

A massive blackout in Santiago de Cuba left the province without electricity after the microsystem established in response to the crisis of the National Electro-Energy System failed.


Santiago de Cuba is entirely without electric service this Saturday, following the disconnection of the microsystem that had been created to generate some energy after the collapse of the National Electric System (SEN) this Friday.

According to the report from the Electric Company of Santiago de Cuba on Telegram, all circuits in the province are currently without electrical service.

The General Director of Electricity at the Ministry of Energy and Mines, Lázaro Guerra Hernández, confirmed in a television appearance and explained that the microsystem of Santiago de Cuba would supply the Renté thermoelectric plant for the synchronization of unit 3, which was in the startup process on the morning of this Saturday.

In the east, the Camagüey microsystem was also ready to supply power to the Nuevitas thermoelectric plant, which was in the process of starting up.

This Friday night, the country experienced a nationwide blackout due to a failure at the Diezmero substation in Havana.

Guerra Hernández reported that currently 225 MW are being supplied from the microsystems that have been created, which are serving vital centers.

He also clarified that the western microsystem, the largest in the country, is awaiting the startup of the Energás plant, which will enable energy to be supplied to several substations in Havana, as well as the thermoelectric plants in Mariel and Santa Cruz, along with the barges.

Until these units are operational, energy cannot be distributed through the various circuits.

The authorities assure that they are working tirelessly to try to reconnect the National Electric System (SEN), amid the frustration, indignation, and distrust of millions of Cubans.

A video shared by journalist Mario Herrera from Canal Habana revealed details about the outage that occurred on Friday at 8:15 PM at the Diezmero electrical substation, located in the San Miguel del Padrón municipality, which caused the system to go down.

Ariel Mas Castellanos, director of substations at the Electric Company of the capital, reported that there was a failure in the insulation of a line component due to many years of operation. "It is aged," he acknowledged.

The specialist reported that due to the conditions of the system in Cuba, they have not been able to replace that device as it is so old that there are no similar ones available in the international market, and it is impossible to find another to replace it.
