Havana<\/strong>.- The process of restoring Cuba’s National Electric Power System (SEN) has begun with the contribution of energy from several generating units, following the new collapse it suffered this Friday, the second this week, as reported by the Ministry of Energy and Mines (Minem).<\/p>\n\n\n\n

The total disconnection of the SEN occurred at 16:30 local time (20:30 GMT) due to a failure in the 220-kilovolt line connecting the cities of Santa Clara and Sancti Sp\u00edritus (center), which “caused the division of the SEN, the shutdown of several thermal units, and an oscillation in the System’s parameters,” according to the Minem.<\/p>\n\n\n\n

Regarding the causes of the new SEN collapse, the general director of Electricity of the Minem, L\u00e1zaro Guerra, explained -to state television- that the shutdown of several generating units occurred “basically as a consequence of electrical storms<\/strong>“.<\/p>\n\n\n\n

However, the official considered it “positive<\/strong>” that there are generating units available to energize the System, which “will be entering into operation in the shortest possible time to reconnect the SEN<\/strong>“.<\/p>\n\n\n\n

Guerra also pointed out that “there are fuel limitations that make the process of recovering the vitality of the SEN more difficult<\/strong>“.<\/p>\n\n\n\n

According to previous experiences, the restoration of the SEN is a slow and laborious procedure that can take days, as it involves starting to generate energy with simple start-up sources (solar, hydroelectric, generation engines) to gradually provide service to small areas that are then interconnected.<\/p>\n\n\n\n

The goal of this process is to get enough energy to the country’s thermoelectric power plants, the pillar of electricity generation in Cuba, as soon as possible, so that they can restart and produce energy in large quantities to try to meet the demand.<\/p>\n\n\n\n

The situation of the SEN is “critical<\/strong>“, as acknowledged by the Cuban Government itself, with power outages in Havana lasting more than 35 consecutive hours and in other regions of the island with up to three days in a row without service.<\/p>\n\n\n\n

Last Monday, another total collapse of the System was recorded, and after that process, it gradually recovered until Wednesday, some 36 hours after the national blackout, the state-owned company Uni\u00f3n El\u00e9ctrica (UNE), which reports to the Ministry of Energy and Mines (Minem), announced that all provinces were connected to the National Electric System (SEN).<\/p>\n\n\n\n

Cuba has been mired in a deep energy crisis since mid-2024, a situation that has worsened over the last several months due to the oil blockade imposed by the U.S., which has pushed power outages to record highs. Last March, the island suffered two national blackouts due to a total disconnection of the SEN in less than a week.<\/p>\n\n\n\n

In recent weeks, record power outages have been reported, with 70% to 72% of the country being disconnected simultaneously during the peak energy demand periods of the longest blackouts.<\/p>\n\n\n\n

On this day, the UNE reported eleven of the country’s sixteen thermoelectric generation units out of operation due to breakdowns or <\/a>maintenance work.<\/p>\n\n\n\n

This situation is explained by the obsolescence of the thermoelectric plants on the island, with decades of operation and without the necessary investments, which causes most of the country’s generation units to suffer breakdowns.<\/p>\n\n\n\n

According to various estimates, the Caribbean island requires a little over 100,000 barrels of oil per day to meet its energy needs, of which the island obtains about 40,000 from its national production. The rest should be obtained from abroad.<\/p>\n\n\n\n

The energy crisis in Cuba has almost completely paralyzed the state economy, which is estimated to contract by at least 6.5% this year (following a cumulative drop of more than 15% in the previous five years).<\/p>\n\n\n\n
