Tuesday was a shock for the electrical generation in Cuba: Over 1,300 MW of blackouts.

With over 1,300 MW of blackouts in Cuba, Tuesday turned out to be a stressful day for customers of the Unión Eléctrica de Cuba (UNE), which had forecasted impacts of 1,030 MW during peak hours.

Awaiting the publication of its daily information note with the data handled by the state-owned company, social media is buzzing with complaints and comments from users reporting massive blackouts of up to 16 hours in various locations across the country.

"From the Telegram Channel of the Mayabeque Electric Company, they report that the country has more than 1,300 MW offline due to a deficit around 9 PM," reported pro-government journalist Lázaro Manuel Alonso on Facebook, where he shared a screenshot with the information provided.

On Telegram, the aforementioned company specified that Mayabeque had "an impact due to a generation capacity deficit of 85 MW" and revealed that "the country has an impact due to a generation capacity deficit of 1,336 MW."

A deficit of that magnitude (1,336 MW) means that the UNE was unable to supply 41.75% of the electricity demanded by its customers, considering that the company itself indicated this Tuesday that the maximum demand would reach 3,200 MW during peak hours.

Almost half of the electricity demand went unmet this Tuesday in Cuba, which could have translated into almost 12 hours of blackout across all circuits connected to the national electro-energy system, or fewer hours in some areas (Havana, for example) and more hours of blackout in the rest (provinces).

At the time of writing this note, the UNE reports that on Tuesday night 1,347 MW were shut down in Cuba, as noted by Alonso on his social media.
