The Provincial Electric Company of Guantánamo informed this Thursday that the shutdown of the 110 kV line connecting Santiago de Cuba to Guantánamo left the entire province without electricity supply, with the cause not being known at the time of the official notification.

The statement, published on Facebook in the usual institutional notice format, briefly mentioned: "Interruption of the 110kv line that supplies the province, Santiago–Guantánamo connection. We are without power in the province. The cause is unknown."

According to neighbors who commented on the post, the outage occurred around 5:20 PM, and the company took a while to provide official information. "That was at 5:20, and they're only now reporting it," wrote one of the users.

The citizens' reaction was one of frustration and irony. "What a coincidence that it's always Guantánamo, the province that gets screwed over, and since we don't matter much, let's just let it happen," published Yasmin Pacheco Rivera.

Another comment pointed directly to the futility of the solutions announced by the regime: "Look at all the panels in Gtmo, I don't know what the hell they're for."

Felipe Adriano Catalá Balón summed up the general sentiment: "The information is fine, but... where is the solution?"

The cut on Thursday occurs on an already severely deteriorated infrastructure.

On June 7th, the Electric Union acknowledged that eight transformers were damaged in the province — three in Baracoa, two in Maisí, two in El Salvador, and one in Manuel Tames — with no physical equipment available to repair them.

In those days, municipalities such as Imías, San Antonio del Sur, Jamal, and Maisí were experiencing up to 20 continuous hours without electricity, a situation that has become routine in eastern Cuba.

The contrast between institutional communication and reality did not go unnoticed. Just the day before, the same provincial electric company had published a text titled "Voices that Illuminate: Call Center 18888", which sparked massive mockery on social media due to the gap between the message and the actual situation.

Guantánamo relies on a single high-voltage line to receive energy from the National Electroenergetic System, which makes it particularly vulnerable to total outages when that line fails. This structural dependence is worsened by the worst electrical crisis Cuba has faced in years.

The national electricity deficit exceeded 2,010 MW during the peak hours on Wednesday, with the country generating barely a third of the electricity it requires. The eastern provinces—Holguín, Granma, Santiago de Cuba, and Guantánamo—are the most severely impacted on a recurring basis, experiencing outages that in some cases exceed 45 consecutive hours.

In March, Cuba experienced a total disconnection of the National Electric System, and in February, the eastern region was completely disconnected due to failures at the Holguín substation.
