Following a partial disconnection of the National Electric System (SEN) occurring at 6:09 a.m. today, the province of Santiago de Cuba has implemented a strategic workflow based on the operation of electrical microsystems. The primary objective of this measure is to ensure the continuity of service for essential installations throughout the region.

According to reports from the Electric Company’s Telegram channel in this southeastern territory, a microsystem was established through the Santiago Este Substation. This configuration provides power to sectionalized circuit 15 and circuit 16, where several vital centers are located.

Additionally, another microsystem is currently operational via the Héctor Pavón substation, servicing circuit seven and reaching the South Children's Hospital "La Colonia." Technical teams are also working on circuit 18, which supplies power to the Provincial Hospital, the Cardiology Center, the Northern Maternal Hospital, and the Northern Children's Hospital.

"Microsystems consist of several interconnected generation sites that operate independently of the SEN to serve a specific load," providing electricity to critical centers during complex situations such as total or partial grid collapses. These systems are also utilized to facilitate the startup of thermal power units.

It should be noted that operations within these microsystems can be unstable. When instability occurs, the circuit may lose power again, a frequent occurrence until the situation is fully normalized.

At the Antonio Maceo Thermoelectric Plant, located in this city, Unit 5 is currently reported as damaged, Unit 6 is undergoing maintenance, and Unit 3 remains out of service due to the partial failure of the National Electric System.
