Cuba’s energy crisis reached critical levels this week after the unexpected exit of the National Electrical System (SEN) by the Antonio Guiteras Thermal Power Plant (CTE), the most important single generation unit in the country. This new failure has caused a dramatic surge in blackouts, leaving more than half of the island without power simultaneously.

The Impact of Guiteras’ Departure

Located in the Matanzas province, the Antonio Guiteras plant is vital for the stability of Cuba’s electrical grid. Its failure and subsequent disconnection, attributed to an unforeseen technical fault, has generated a deficit of more than 1,800 MW during peak demand hours. According to reports from the state-run Unión Eléctrica (UNE), power outages have reached up to 53% of the national territory.

This scenario adds to a precarious situation characterized by fuel shortages and several other generating units that are currently offline for maintenance or chronic breakdowns.

Compromised Stability and Fuel Scarcity

In addition to mechanical failures in ancient thermoelectric plants, a lack of fuel, including diesel and fuel oil for distributed generation units, exacerbates the massive disconnections. In rural provinces, residents report power cuts exceeding 15 hours a day, affecting essential services like water supply and food preservation.

Authorities have stated that work is being done “uninterruptedly” to return the Matanzas unit to the system, though no exact timeline for total restoration has been provided.

Frequently Asked Questions (FAQ)

1. Why did the Antonio Guiteras thermal plant go offline? The plant suffered an unexpected mechanical failure that forced its immediate disconnection to prevent further damage, according to official UNE notes.

2. How large is the current electrical deficit in Cuba? The deficit has exceeded 1,800 MW, representing a massive impact affecting more than 50% of the country’s consumers simultaneously.

3. Which provinces are most affected by the blackouts? While the deficit is nationwide, central and eastern provinces typically experience the longest outages due to the grid’s configuration.

4. When is an improvement in the electricity situation expected? Improvements depend on Guiteras returning to service and the arrival of new fuel shipments, though the crisis remains structural and persistent.
