The Electric Company of Santiago de Cuba issued an official statement this Tuesday warning the public that, when restoring electric service, they should connect their devices gradually and avoid turning on high-consumption equipment simultaneously, as the microsystems operating in the province are fragile and may collapse under any overload.
«Once the electricity service reaches your home, connect the devices gradually. Avoid connecting high-consumption devices simultaneously to maintain the stability of these isolated systems,» stated the Electric Company in its official statement.
The warning not to connect all the equipment is due to a specific technical risk: when dozens of users turn on air conditioners, refrigerators, and televisions at the same time, the peak demand can exceed the capacity of the microsystem and cause a new cascading disconnection.
"It is crucial for our clients to understand that these are isolated and vulnerable systems, which makes them prone to failures or sudden interruptions during the contingency," the entity added.
The notice comes as the country attempts to recover from the fifth total blackout of the National Electric System in 2026, which occurred due to "a fluctuation in the system parameters with a sudden change in frequency" at the Feltón thermoelectric plant.
The entity reported that, after activating microsystems throughout Cuba, in Santiago de Cuba, circuits 7, 15, 10, and 18 are already operating in a sectionalized mode, prioritizing in the first instance the areas where hospitals and other vital centers are located.
The microsystems operating in Santiago de Cuba run on engines from the Santiago del Este and Pavón plants, and also serve a technical function: to supply the Renté thermoelectric plant to synchronize its unit 3 and, eventually, reconnect the province to the national grid.
