Havana reports 168 circuits affected by blackouts at the close of the evening on October 31

As of 18:05 on Saturday, October 31, the Electric Company of Havana reported 168 affected distribution circuits due to a generation deficit in the capital, with an impact of 385 MW, according to records from the CiberCuba Outage Observatory.

That afternoon balance does not represent the most critical point of the day: in the early hours of the same day, the capital had reached 460 MW and 195 affected circuits, and by 9:32 in the morning, the figure was 234 MW and 102 circuits.

Among the longest documented cases at the same cutoff, the circuits R461 and R464 in the municipality of Regla each accumulated 25 hours and 16 minutes of disruption, attributed to a generation deficit according to the electric company itself.

The R461 covers areas of Maceo Street and 27 de Noviembre Street in Regla, while the R464 encompasses Reparto Modelo, Alturas de Vía Blanca, Habana Nueva, La Cotorra, and Villa 1, also extending to Guanabacoa.

The Observatory's records note the accumulated duration at the time of the cut, without specifying whether there were any intermediate restorations or if the circuits were still out of service at the time of publication.

The report from Saturday comes against the backdrop of a week marked by ongoing electrical crises. On Friday, October 30, Havana had recorded 173 affected circuits and 355 MW at 6:00 AM, with the VC100 circuit in Arroyo Naranjo experiencing 64 hours and six minutes without electricity.

Nationwide, the week recorded provincial disconnections from the National Electric Power System: Santiago de Cuba and Guantánamo on October 25, Granma on October 26, Pinar del Río on the 27 for 46 minutes, and Guantánamo again on the 30th.

The Antonio Guiteras thermoelectric plant —the largest in the country, located in Matanzas— went offline on October 27 due to low vacuum in the condenser; an inspection detected three simultaneous failures in the boiler. The Union Eléctrica report from October 31 noted 668 MW of limitations in thermoelectric generation, with several units out of service at different plants across the country.

For the peak consumption period on Saturday, the Electric Union forecasted only 1,020 MW available against a demand of 2,800 MW, with an estimated shortfall of 1,810 MW, although that figure was a forecast and not a confirmed result at the available cut.

The CiberCuba Blackout Observatory documents what is reported by state electricity companies and does not provide an independent verification of the data. As noted in the context of the day on October 31, Cuba reached the last day of the month facing a crisis that combines several days of blackouts, breakdowns at thermoelectric plants, and failures in provincial interconnection lines.
