Cuba's electric grid collapses again as government tries to resolve previous day's blackout

Cuba's Power Grid Collapses Again, Triggering Nationwide Blackout

Cuba's national electricity grid collapsed late on Sunday, plunging the entire island of about 10 million people into darkness, according to multiple reports. The state-run utility Unión Eléctrica (UNE) announced a "total disconnection" of the national electricity system on social media, but did not immediately provide details on the cause or the expected duration of the outage, as reported by Al Jazeera and Deutsche Welle.

The collapse is the latest in a series of major failures. Cuba experienced three nationwide blackouts in July, including two within the same week, which left millions without power and highlighted the country's ongoing energy crisis, as noted by Al Jazeera and the Jerusalem Post. Sunday's outage came just a day after the western part of the country went dark, according to France 24.

Residents in Havana, who had been sitting outside to escape the summer heat, audibly groaned as the lights went out, France 24 reported. In other areas, people expressed frustration by setting trash on fire and banging pots and pans. The outages have disrupted transport, water supplies, communications, and medical services, making daily life increasingly difficult, as Al Jazeera and France 24 noted.

Causes and Contributing Factors

Reports uniformly attribute the crisis to a combination of aging infrastructure, fuel shortages, and the US embargo. Cuba relies largely on old oil-fired power plants, and the system has deteriorated due to a lack of replacement parts and repeated breakdowns, according to Al Jazeera and Deutsche Welle.

A key factor, as described by several outlets, is the loss of fuel supplies from Venezuela, which had long been Cuba's primary oil supplier. The US, under President Donald Trump, imposed an oil blockade after Washington deposed Venezuelan President Nicolás Maduro in January, according to Deutsche Welle and the Jerusalem Post. Subsequently, fuel imports from Mexico, which had become Cuba's key supplier, also ceased under US pressure.

Washington authorized the arrival of only one Russian tanker carrying 100,000 tons of crude, which arrived in March, but those reserves have since been exhausted, as reported by Deutsche Welle and France 24.

Beyond the oil blockade, US sanctions against Cuban state-owned businesses have led many foreign companies to suspend operations on the island, further straining the economy, according to Deutsche Welle and France 24.

Differing Interpretations

The causes of Cuba's energy woes are a matter of contrasting viewpoints. Havana blames the decades-old US trade embargo for its failing infrastructure, a position echoed in reporting by the Jerusalem Post. On the other hand, Washington contends that the blackouts stem from the mismanagement of Cuba's state-run economy, as noted in the same Jerusalem Post report. This division reflects the broader political tensions between the two countries.

Government Response

The Ministry of Energy said that protocols to reactivate the grid were underway, as reported by Deutsche Welle and France 24. Authorities typically attempt to restore power by creating small, isolated networks to supply hospitals and water systems before reconnecting larger plants, according to Al Jazeera. However, in past incidents, the country struggled to meet demand even after the network was reconnected.

As the crisis continues, Cuba has seen a cautious opening of its energy sector, with Havana recently authorizing its first foreign-backed fuel import venture, according to the Jerusalem Post. The situation remains fluid, with further outages possible as the government works to stabilize the grid.
