The Antonio Guiteras Thermoelectric Power Plant, Cuba's largest electricity generator, reconnected with the National Electric System this past Sunday, boasting an output exceeding 100 MW. This news was shared on Facebook by José Miguel Solís, a journalist with Radio 26 who frequently covers updates on the Matanzas-based plant.
According to the state-run agency ACN, the plant was synchronized at 9:33 AM, with later updates indicating it was contributing over 100 MW to the system. While this might sound promising, the reality is less so. The plant has a nominal installed capacity exceeding 300 MW, and due to the lack of significant maintenance since 2010, each restart is a gamble.
Cubans' skepticism is not unfounded. On September 27, the Guiteras managed to sync with around 150 MW only to be knocked offline hours later due to a reheater failure. By September 30, it remained out of commission with a reconnection planned for October 2 that failed to materialize.
Social media reactions to news about the Guiteras are typically a blend of dark humor and resignation. "Let's see for how long," one user commented, encapsulating the widespread doubt in four words. Others turned to faith, with comments like "Solís, may God hear you," "May God keep it running, amen," and "Our Father, who art in heaven... Amen." Another user, with less mysticism and more practicality, simply hoped, "Don't jinx it."
The sharpest irony came from those experiencing the contradiction firsthand: the plant is operational, yet their homes remain in darkness. One netizen lamented, "The Guiteras is running, but the power is gone, just 5 hours in Las Guásimas, what a frustration." From Santa Marta, someone questioned, "For whom? In Santa Marta, it's over 35 hours of blackout and only two of electricity." Meanwhile, a user in La Lisa reported just three hours of power for the entire day.
The broader context explains the cautious reception of the news. Cuba has faced frequent generation deficits exceeding 2,000 MW in recent months, with eight total system failures this year alone, the latest occurring on September 18. The Guiteras plant itself has experienced at least 17 unscheduled outages in 2026, plagued by recurring issues with its economizer, boiler, and reheater.
Even with the plant online on Sunday, several provinces were still experiencing power disruptions. The Guiteras' contribution remains insufficient to meet the country's actual demand.
"Power plants break down, get fixed, and we remain in the same situation: a few hours of electricity, and then you know the rest," summarized one netizen, capturing the cycle that Cubans have endured for years. It's a fitting description of Cuba's electrical grid status in 2026.
Understanding the Challenges of Cuba's Power Grid
Why is the Antonio Guiteras plant important to Cuba's power supply?
The Antonio Guiteras plant is significant because it is the largest power generator in Cuba, with a nominal capacity of over 300 MW. Its operation is crucial for meeting the country's electricity demand.
What are the main issues facing the Guiteras power plant?
The main issues include frequent unscheduled outages and recurring technical problems with its economizer, boiler, and reheater. The lack of major maintenance since 2010 exacerbates these problems.
How do Cubans typically react to news about the power plant?
Cubans often respond with skepticism, humor, and resignation. Many have lost faith in the plant's reliability due to its history of frequent failures and outages.
