Cuba's National Power Grid Partially Restored Amid Public Outcry...

Qué pasó

Cuba's National Electrical System (SEN) has been partially reconnected, spanning from Pinar del Río to Nuevitas. This announcement came while many citizens reported still being without electricity for over a day following a widespread blackout.

Several power facilities, including the Boca Jaruco combined cycle plant and units at the Mariel and Santa Cruz thermal power plants, had begun stable electricity generation. Two units at the Carlos Manuel de Céspedes plant were in the process of starting up.

Dónde y cuándo

The nation experienced a total blackout on Friday, September 18, 2026. The emergency began when two 220-kilovolt transmission lines, Matanzas-Cienfuegos and Matanzas-Santa Clara, successively went out of service.

Unstable weather conditions were also cited as a factor during the incident. The subsequent loss of these lines led to the total disconnection of the SEN. The recovery efforts focused on creating micro-systems and gradually bringing generating units back online, prioritizing essential services.

Por qué es importante

The partial reconnection signals a step towards normalizing power supply, but the continued outages highlight the fragility of Cuba's energy infrastructure. This is the eighth total disconnection of the SEN in Cuba during 2026, indicating ongoing systemic issues with electricity supply stability.

The discrepancy between official announcements of restoration and the reality on the ground fuels public dissatisfaction and underscores the daily challenges faced by residents. It affects communication, services, and general quality of life across the island.

Qué dicen las partes

The Ministry of Energy and Mines (MINEM) announced the partial SEN interconnection on Saturday, September 19, 2026, listing the facilities contributing to the recovery. This announcement was made via social media, including a tweet from the official @EnergiaMinasCub account.

However, citizens on social media expressed skepticism and frustration, with reports from Santa Clara and Baire indicating a continued lack of electricity. The Unión Eléctrica (UNE) noted that unstable weather contributed to the initial failure.

Qué viene ahora

The recovery process is ongoing, with gradual incorporation of generating units. A further complication arose from a new breakdown at the Antonio Guiteras thermoelectric plant in Matanzas, where a boiler economizer issue could require up to 72 hours for inspection and cooling.

Citizens will be observing further updates on the full restoration of power and the resolution of the new issue at the Guiteras plant. The recurring nature of these blackouts suggests continued monitoring of Cuba's energy sector is warranted.
