The Cuban National Electric System (SEN) experienced a total collapse on Monday, as the state-run utility La Unión Eléctrica (UNE) confirmed a new island-wide blackout. This follows the sixth total system failure of the year, which occurred late Sunday evening, leaving millions without power as the country struggles to restore a fragile electrical grid.
Causes of the Latest National Blackout
La Unión Eléctrica attributed the latest disconnection to adverse meteorological conditions. In a statement posted to its official Facebook account, the company reported that, during the restoration process, weather-related events caused damage to the network, which directly affected power-generating units already connected to the grid. The company stated it is working to reverse the situation and restore the system as soon as possible.
Prior to the official announcement, Lázaro Manuel Alonso, a journalist, reported that the system had experienced an “oscillation” that led to the collapse. This occurred despite efforts made throughout the day to bring units back online.
Did you know?
The Antonio Guiteras thermoelectric plant, the largest plant in the country, had initiated a “cold start” at 10:17 a.m. on Monday, with expectations to synchronize it with the national grid by nightfall before the latest collapse occurred.
Fragility of the Recovery Process
The failure highlights the instability of the Cuban energy sector. As of Monday morning, only 14% of the electrical supply had been restored in Havana. According to official figures, this recovery provided approximately 78.51 MW to 87,480 customers. Efforts were concentrated on critical infrastructure, including 19 hospitals and two water pumping stations, as the government prioritized essential services while the rest of the nation remained in the dark.
Impact on Telecommunications and Connectivity
The electrical crisis has extended beyond lighting and appliances, significantly affecting communication networks. The Empresa de Telecomunicaciones de Cuba (ETECSA) issued a notice on Monday confirming nationwide service disruptions for mobile telephony. The company attributed these issues to the breakage of the generator set providing backup power to one of its primary centers. The impact is primarily affecting users with phone numbers starting with the prefixes 52, 509, 598, and 599.
