Jorge Piñón, a renowned researcher at the Texas Energy Institute, has dismissed the idea that the widespread blackout affecting 80% of Cuba—from Camagüey to Pinar del Río—is due to the feared "zero option" scenario.
Piñón explained in a statement to CiberCuba that similar situations in the past were caused by a technical failure, such as at the Guiteras plant, which triggered a domino effect throughout the system. "It's not a lack of fuel," he emphasized.
He elaborated that the use of Cuba's heavy crude oil, which is rich in sulfur and metals like vanadium, is causing significant corrosion to the components of the country's thermoelectric plants.
Despite having enough domestic crude oil to sustain base generation at these plants, Piñón's analysis indicates that this fuel is rapidly wearing down the facilities. "Using national crude oil creates a vicious cycle: they repair damaged components, and within months, the damage recurs," he noted.
Highlighting the technical aspects, Piñón clarified that a failure in one plant can cause a systemic collapse, likening it to a row of dominoes where one piece falling leads to the downfall of the entire setup. This scenario has been observed before with the Antonio Guiteras thermoelectric plant.
Beyond technical challenges, Piñón pointed out that the thermoelectric plants also face issues of resource scarcity. "The real challenge is securing funds and time for long-term solutions, rather than temporary fixes," he stated.
He further emphasized that the shortage of diesel fuel directly impacts distributed generation, which relies on this fuel for electricity production.
The massive blackout on March 4 left about 80% of Cuba in darkness, affecting around 7 million people across at least 10 provinces, including Havana. This was due to the unexpected shutdown of the Antonio Guiteras thermoelectric plant, the largest in the nation.
The malfunction at this plant led to a partial disconnection of the National Electroenergetic System (SEN), causing a chain reaction that disrupted the electrical grid. The regime claims efforts are underway to pinpoint the issue and restore service, a process anticipated to take up to 72 hours to complete.
Understanding Cuba's Electrical Challenges
What caused the widespread blackout in Cuba?
The blackout was primarily caused by a technical failure at the Antonio Guiteras thermoelectric plant, leading to a domino effect that affected the entire electrical system.
How does Cuba's crude oil affect its power plants?
Cuba's heavy crude oil contains high levels of sulfur and vanadium, which cause accelerated corrosion in thermoelectric plant components, leading to frequent breakdowns.
What is the main challenge facing Cuba's thermoelectric plants?
The primary challenge is securing the financial resources and time necessary for long-term, sustainable solutions rather than relying on temporary repairs.
